causes of hair loss 


what is hair loss?

Hair Loss can occur at any time and can be very distressing & worrying.

It could present itself as shedding & thinning throughout, thinning in specific arrears, patches of complete hair loss or total hair loss all over the head.

When searching for a resolution with either hair extensions or a hair replacement system it is extremely important to establish the cause.

Applying additional weight to any hair in the resting phase or actively shedding can accelerate the process, leading to further loss.

Many hair loss conditions can improve once you know the underlying cause and can be tackled with the correct treatment plan. 

Hair Extensions or predominantly a Hair Replacement System can be worn whilst the hair is in recovery , they can actually help improve some conditions / causes & support you along the way as a temporary measure..

Unfortunately some hair loss conditions are progressive and will not improve with treatments.  Hair Replacement Systems will become an ongoing commitment both financially, emotionally & time allocated for regular appointments. 

Differing conditions will progress at different rates, with some you may see noticeable progressive loss at each of your refit appointments & for others the loss rate is much slower and may not be noticeable for several years. 

Some clients may have experienced hair loss & their hair has never grown back to its previous state, yet it is stable, no losses, no improvements. 

Wearing a Hair Replacement System or Hair Extensions should not have an adverse effect nor should you expect improvement.  


the hair growth cycle

It is also important to know that our hair goes through 4 stages of the growth cycle and each individual hair will be at different stages throughout the head. When the cycle is interrupted / altered by a change this will not see an immediate effect. You may not notice any change until many months later due to the timescale of each cycle.

This is the same for treatment plans, you will not notice any improvements until many months later, so you must have faith and persevere. 



Anagen is the active growth phase during which the root of the hair is dividing rapidly and adding to the hair shaft.  The hair grows approximately 1cm every 28 days during this phase. 

INTERESTING FACT: Hair grows faster during summer than in winter.


The transitional phase is where hair growth stops. This lasts approximately 10 days.  The hair follicle shrinks and detaches from the Dermal Papilla. (The Dermal Papilla are a collection of finger - like   cells which are responsible for the cycling portion of the hair follicle and generation of the  hair shaft.)


This is the resting phase which lasts approximately three months. The hair is no longer growing and the hair follicle is completely at rest and  completely cut off from the nourishing blood supply. A club hair is formed.  Club hair is the end product of final hair growth and features a bulb of keratin (protein) at the root of the hair shaft. 

The bulb remains within the follicle until it sheds .

Whilst the old hair is resting a new hair begins to form and grow beneath.

Hair can remain in the resting phase between 2 - 4 months.


This is the active shedding phase where the resting hairs are expelled from the head. 

This can last between 2 - 5 months. On average we naturally shed between  50 - 150 club hairs a day. and is considered normal hair shedding.  

*The club hairs are what is contained within the hair extension attachments as they have been unable to fall. The white bulbs are clearly visible and no cause for concern.


New hair is already formed within the follicle and as it grows it softens the anchor point of the hair shaft. holding the old club hair in place. The hair base will break free from the root and the old hair will shed.  And the hair growth cycle begins again.


genetic factors

Genetics play a huge part in hair loss. 

These are inherited age - related conditions that can trigger hair loss and can be inherited by either your Mother or your Father.


Andrgenetic Alopecia is otherwise known as Male / Female Pattern Baldness the amount of time the hair is actively growing. is reduced. This is caused by a reaction and change to the hormone Testosterone  which converts into the sex hormone Dihydrotestosterone (DHT).

DHT can link to the receptors in the hair follicle. This shortens the hair cycle, so it spends less time growing before it falls out. The new hairs replacing it are finer due to the shrinkage of the hair follicle.

Eventually the follicle shuts down entirely.


Women with Polycystic Ovary Syndrome produce higher levels of testosterone so are at higher risk of developing Androgenic Alopecia. 


 A genetic disorder that effects the production & function of Hemoglobin causing red blood cells to break down more easily than normal, which can lead to Anaemia. Red blood cells transport oxygen to the cells including the hair follicles which also deliver vital nutrients. delivering vital nutrients.


Is an inherited genetic disorder in which there aren't enough healthy red blood cells to transport oxygen through the body. This disease causes red blood cells to be distorted or misshapen. 

*ANAEMIA is discussed further in our the DIET & NUTRITION section


 is a rare disorder (non genetic) which is characterised by hair that can be very easily & painlessly  pulled out. Hair density may be reduced in localised areas of the scalp or diffusely. Completely bald areas are not a characteristic of this syndrome.  the most frequently found areas of hair loss will be in the vertex and occipital scalp. The occipital area can be rough and sticky and wont lie flat. The hair may lack shine and the ends of the hair all uneven lengths. 

Although the majority of the hair will be in the Anogen Phase loose Anogen Syndrome is believed to be caused by defective anchoring between the hair shaft and inner root sheath.  Also in some patients the lack of an external epithelial sheath (The outermost layer of the root bulb) leading to defective anchoring of the outer root sheath & the inner root sheath.

The hair grows back quickly. and generally the condition usually improves with age. (Usually after puberty)  It predominantly effects blond females in childhood.


Is a recently recognised non genetic, congenital condition where the hair does not grow very long due to an abnormally short Anogen phase.. It is characterised by persistently short hair since birth and  commonly noticed in children from the ages of 2-4 . 

It is commonly also accompanied with Telogen Effluvium. 

The hair shaft is normal apart from its short length, hair density is normal, the hair is not fragile and does not break easily. A 'Pull Test" is often normal.  

Most reported cases of Short Anogen Syndrome persist into adulthood.

There is no 'cure' for hereditary hair loss as this is in your genetic code but there are treatments available. 

These may be products taken orally or topical solutions directly applied to the scalp by either in pure form or combination solutions or as an ingredient in shampoos & conditioners.

BLOCKERS - prevent DHT binding to the receptors in the hair follicle preventing shrinkage.

INHIBITORS - reduce the production of DHT.


Finasteride (Proscar, Propecia) is a prescription - only oral medication. 

Finasteride binds to 5-AR proteins to block DHT from binding with them. This helps to stop DHT from binding to the receptors in the hair follicles & helps to prevent them from shrinking.


Minoxidil (Regaine) is a peripheral vasodilator which helps widen and loosen blood vessels so that blood can pass through more easily.  Typically a blood pressure medication but can help promote hair growth when topically applied to the scalp.


Ketoconazole is an anti - fungal medication. It is commonly used to reduce dandruff and is believed to also block DHT & promote hair growth. Studies have suggested that topical use of Ketoconazole in conjunction with Minoxidil stimulate more hair growth than Minoxidil alone. 


Biotin is Vitamin H and is a natural B vitamin that helps to turn some food & liquids into energy.

Biotin helps to boost and maintain levels of keratin the protein found in your hair, nails & skin.  It is not scientifically proven why keratin improves keratin levels however a 2015 study suggested that it supports hair regrowth and keeps hair in the growth stage for longer.


Pygeum is a herb extracted from the bark of the African Cherry Tree.  It is a herbal supplement & taken orally.

It is well known for its benefits as a DHT blocker used in the treatment of enlarged prostates and prostatitis. 


Pumpkin seed oil is natural supplement and taken orally. It is a known DHT blocker. A study of 76 men in 2014 showed taking a therapeutic dose of 400milligrams a day saw a 40% increase in average scalp hair over 24 weeks


Saw Palmetto is derived from a small palm tree native to Florida. It is a DHT blocker. The most potent form of Saw Palmetto is the extract.


Nettle Root acts as a DHT blocker by inhibiting 5 - alpha reductase.


Lycopene is a pigment compound known as Carotenoid. It is a powerful antioxidant which neutralises free radicals that cause damage to cells & DNA.

It is understood that Lyposene inhibits the effects of DHT by modulating insulin - like growth factor (IGF) This means it promotes & supports hair follicle growth.

Lycopene can be found in:

  • Grapefruit
  • Apricot
  • Pink Guava
  • Watermelon
  • Tomatoes 


Green Tea is packed with vitamins & nutrients. It contains a group of water - soluble polyphenols known as Catechins.  Catechins prevent buildup of fats in your arteries promoting healthy function of your blood vessels. Healthy blood flow will ensure delivery of nutrients to the hair follicles. 

The major polyphenol in green tea is epigallocatechin - 3 gallate (EGCG). 

ECGC is a direct androgen antagonist and helps blunt DHT receptors and inhibits 5 - alpha reductase promoting hair growth.


Fenugreek acts by inhibiting 5 - alpha reductase.


Soy contains many compounds which promote healthy hair growth. It contains the following 5 - alpha reductase inhibitors:

  • Biochanin A
  • Equol
  • Genistein


Flaxseeds & sesame seeds are a natural DHT blocker and inhibit  5 - alpha reductase. They can be easily incorporated into the diet either milled into a powder or sprinkled. 


Tea Tree Oil interacts with and blocks the DHT receptors at the hair follicle. Applied topically to the scalp.


Lavender oil applied topically to the scalp can promote healthy hair growth by increasing the number of hair follicles, hair follicle depth & dermal layer thickness which all contribute to increased hair growth


Rosemary Oil & Rosemary Oil Extract is an analgesic with anti fungal, anti bacterial and anti inflammatory properties. It is found in many hair loss products. Topical application of rosemary oil inhibits 5 - alpha reductase by blocking the DHT from connecting to the receptors in the follicles preventing hair loss and follicle miniaturisation.


Caffeine has been found to stimulate hair follicle growth and keeps the hair in the active growth cycle for longer when applied topically.  Whilst further research is necessary it is also thought it has the ability to block 5 - AR receptors.




psychological disorders

Stress, which can lead to depression and anxiety have a physiological and psychological effect. These factors can  trigger the most recognised psychological hair loss disorder, Trichotillomania.




trick-o-till-o-may-nee -ahh

Trichotillomania (self hair pulling) is a complex psychological disorder in which the sufferer has an irresistible urge to pull out their hair. (This can be from the scalp or any part of the body)

It is a very distressing mental health disorder classified under Obsessive - Compulsive & Related Disorders. 

Hair pulling is triggered or accompanied by several emotional states.

Stress, depression, anxiety, trauma, tension and boredom can trigger the urge which is followed by feelings of relief, gratification or pleasure. These can then be followed by feelings of disgust, self loathing, disappointment which lead to further stress, anxiety, depression and tension, creating a continuous cycle.


Engaging in focused hair pulling with the intension of experiencing tension relief. This can include specific rituals and certain types of hair.

The sufferer is fully aware of the pulling.


This can occur during boredom, tiredness, watching TV. The sufferer engages in hair pulling without fully realising .


Many trichotillomania sufferers engage in both behavioural traits.


Treatment for trichotillomania can be complex . It is a mental health disorder and requires professional intervention.

It won't go away on its own. It will require time, patience and practice and several strategies may be used to help cope with the urges.


Learning how to recognise situations where pulling is likely to occur and substituting with other behaviours.

This can be using a journal, alerts and strategies to increase awareness of triggers. Replacing hair pulling with other behaviours such as clenching fists, clicking fingers, snapping an elastic band on the wrist, turning a ring on the finger, turning a bangle on the wrist, playing with a fidget spinner or fiddle toy.


This is a talking therapy based on the concept that your thoughts, feelings, physical sensations and actions are interconnected and negative thoughts and feelings can lead to being trapped in a cycle. 

Cognitive behavioural therapy examines  your thoughts with a behaviour approach ( looking at the things you do) as both influence each other. The aim is to break down overwhelming problems into smaller segments making them easier to manage.

The idea behind CBT is to change negative thought patterns and distorted beliefs and connected behaviours and changing them into positives.


Learning to become aware of hair pulling patterns, tracking and documenting when it occurs and detailing emotions and relevant information.


Learning to focus and remain calm to help control the response to stress triggers.

Deep Breathing, Yoga, Reiki, Mindfullness, Massage & reflexology are all examples of relaxation therapies.


There are no specific medications to treat trichotillomania but some anti depressants can be used to treat depression & anxiety which can be triggers.


Connecting with others and sharing experiences can help with feelings of isolation and offers support to yourself and others


Alopecia is a complex hair loss condition and is recognised as a psychological and an autoimmune disorder. 

The psychological factors of stress , anxiety and depression can be a trigger which raises cortisol levels. The immune system is lowered due to chronic stress and an autoimmune response is triggered resulting in the onset of Alopecia.

This returns to the psychological effect as the change in appearance due to the hair loss can trigger other psychological disorders such as major depression, anti social personality disorder, obsessive compulsive disorder, social phobia, panic disorder. 

Many people who experience alopecia become withdrawn and relationships and self esteem suffer. 

Many medical approaches to psychological disorders are the prescription of anti depression medications. Whilst theses are beneficial for the disorder, many have hair loss listed as a side effect. 


hormonal changes

(inc pregnancy & menopause)

Hormonal changes have a huge impact on the hair. 

The most common hormonal changes in women are during pregnancy and post birth and later during menopause. 

Hormonal changes can also occur with underlying thyroid conditions.


Normally during pregnancy the hair remains in the growing phase for longer due to the increase in Oestrogen. However for some women pregnancy leads to low iron levels (anaemia).

The body relies on the iron in red blood cells to carry oxygen to all it's other cells.  When a decrease in the red blood cells occurs the vital organs to work twice as hard to deliver oxygen around the body leading to fatigue, shortness of breath, difficulty concentrating, restless legs, pale skin, leg cramps. Vital nutrients are also unable to reach the hair follicles. As the body views hair as a non essential protein it can enter the resting phase and shed excessively

The body also stores iron in a protein known as ferritin. Ferritin is released when your body needs it. It lives within the cells with very little circulating in the blood. 

Healthy ferratin stores are within a typical range of 12 to 150 nanograms per millilitre in women & 12 - 300 nanograms per millilitre in men.

The normal haemoglobin iron level (abc) is 12.0 - 15.5 grams per decilitre for women and 13.5 - 17.5 grams per decilitres for men.

During pregnancy some women experience Hyperemesis Gravidarum (severe morning sickness) This means the body may not be absorbing enough nutrients. This can cause a disruption to the hair growth cycle and cause diffuse shedding.


During pregnancy the oestrogen levels rise over the course of 40+ plus weeks.

Rapidly during the first trimester (which can cause morning sickness) 

During the second trimester it is fundamental to the development of the milk ducts and enlargement of the breasts to produce breast milk. 

Oestrogen keep the hair in the growing cycle for longer. Post birth the oestrogen levels drop rapidly which can interrupt the hair growth cycle. The additional hair which remained growing for a longer period will enter the resting then shedding phase. 

If a woman continues to breast feed the oestrogen levels will remain higher, so the hair will remain in the growth phase for longer. Once breast feeding stops or reduces the levels drop and the hair will enter the resting then shedding phase. 

This can happen for up to a year post partum or the end of breastfeeding. 

Hair growth will return to normal when the hormone levels have regulated.


During menopause the levels of oestrogen and progesterone are lowered. Both hormones keep the hair in the growth phase for longer, with lower levels the hair can enter a faster shedding phase and grow much slower causing the hair to thin.


Some hormonal based contraceptives can cause Telogen Effluvium by a hormone change, interrupting the hair growth cycle. 

Birth control pills prevent the surge in oestrogen which cause the ovaries to release an egg.  or some women who are sensitive to these hormonal changes may  experience excessive shedding due to the lower oestrogen levels. 

Hormone injections such as Depo - Provera,  skin patches such as Xulane, progestin implants such as Nexplanon and the Mirena coil can cause or worsen hair loss.

(under active thyroid gland)



stress & trauma

Stress and Trauma have a physiological and psychological effect which can have a significant impact of hair growth and trigger hair loss.

Stress will not result in immediate hair loss and won't present itself until around 6 - 12 weeks or longer after a stressful event.  This is down to the hair growth cycle, 

This is why stress management is so important as stress levels can increase when hair loss occurs creating an ongoing cycle. 

When we are under stress we often neglect ourselves by not eating properly.  and the body is denied of nutrients and calories for energy. 

Hair is a non essential tissue so the body will use the little nutrients & energy it is receiving to survive. As hair is non essential it is often the first thing to be negatively impacted. 

Stress effects the body's immune system making us more prone to illness. Immune system disruption can trigger hair loss.

The types of hair loss most related to stress are:

  • Telogen Effluvium (excessive daily hair shedding)
  • Alopecia Areata (hair Loss in patches)
  • Trichotillomania (hair pulling)
  • Androgenic Alopecia


(Alternative name Hydrocortisone)

Cortisol is a steroid hormone that is vital in the regulation of a wide range of processes in the body such as metabolism, acts as an anti inflammatory & immune response, influences blood pressure and controls blood sugar levels and how the body responds to stress. 


Cortisol (known as the stress hormone) is made in the cortex of the adrenal glands. When the body perceives stress cortisol is released into the bloodstream.

The hormone triggers a flood of glucose that supplies an immediate energy source to your large muscles, but inhibits  insulin production so the glucose is not stored and available for immediate use. Cortisol narrows the arteries, whilst another hormone, epinephrine, increases the heart rate. Together they force your blood to pump harder and faster as you confront the 'threat'.

This is know as 'fight or flight' as a reaction to stressful situations.

During periods of high, chronic stress your body may constantly produce and pump out cortisol.

Almost every cell contains receptors for cortisol so it has many  different  actions depending on each cell type.  


These effects include  controlling  blood sugar levels therefore regulating metabolism,. Cortisol stimulates fat and carbohydrate metabolism to create fast, instant energy. This then stimulates insulin release & maintenance of blood sugar levels. As the cells cry out for energy these actions can increase appetite through false hunger signals & cause cravings for sweet, high fat, high calorie foods. These foods often have low nutrient values so will lacking nutrients vital to healthy hair growth and as the body view hair as non essential tissue it begins to suffer.

Unused glucose in the blood is stored as fat, resulting in weight gain.  Weight gain alone can cause additional stress and the cycle continues.


As the body reacts to a 'threat' it shuts down other critical functions. One being digestion. With constant stress levels the digestive tract cant digest or absorb food well, again the body is not receiving essential nutrients.


Fatigue is a very common symptom of high levels of cortisol. (Adrenal Fatigue)

It creates the feeling of overwhelming tiredness & lack of energy or motivation.

This is where lack self care and poor diet can occur.  A poor diet will lead to malnutrition denying the body of vital nutrients essential to healthy hair growth which can lead to hair loss.  Lack of nutrients also lower the immune system leaving the body more susceptible to illnesses such as virus'

Virus' can trigger autoimmune responses , causing autoimmune disorders. Some autoimmune disorders are contributory factors in hair loss. 


Sustained chronic stress with elevated cortisol can lead to decreases in serotonin and other neurotransmitters in the brain including dopamine which are all linked to depression. Depression causes fatigue which can lead to poor self care and poor diet either by over eating and craving high sugar, high calorie foods low in nutritional value and leading to weight gain or loss of appetite again causing nutrient deficiency which can lead to hair loss.

Depression is a mental health illness and can trigger eating disorders.

Anxiety can trigger the ' fight or flight' response which releases more cortisol into the blood stream. 

It is common for depression and anxiety to be treated with anti depressants. 

A side effect of some anti depressant medications can be hair loss.


Constricted arteries and high blood pressure can lead to blood vessel damage and plaque build up in the arteries. (Heart Disease) Constricted blood flow can restrict the delivery of vital nutrients to the hair follicles.


When high levels of cortisol are present the adrenal glands begin to produce fewer hormones that promote hair growth. Without the presence of those vital hormones then normal hair growth is interrupted. Interrupted hair growth is the cause of Telegen Effluvium.


Cortisol is an anti - inflammatory and contains the immune response. Chronic elevations can lead to the immune system becoming 'resistant'. The accumulation of stress hormones and increased production of inflammatory *cytokines further compromise the immune response. 

*Cytokines are a large group of proteins that are secreted by the specific cells of the immune system. They are signalling molecules that mediate & regulate immunity.

Stress also decreases the body's lymphocytes - the white blood cells that help fight infection..

Lets explore all four main hair loss conditions attributed to stress.


Telogen effluvium is diffuse hairloss throughout the scalp. Noticeable by the presence of excessive daily shedding.

It occurs when an internal disruption occurs within the body. More hairs in the Anagen phase (actively growing) are halted & growing stops. The hairs enter the catagen phase (resting) before rapidly moving into the telogen phase (shedding) 


Alopecia Areata is hair loss in areas. it causes bald patches, usually circular in appearance and they can differ in size.  

Alopecia areata is accepted as an autoimmune disorder. The body identifies certain hair cells as a foreign body and begins to attack the cells.

Autoimmune disorders are often triggered by a recent illness such as a viral infection.  


Androgenic alopecia is commonly referred  to as male / female pattern baldness. It is Is caused by the conversion of testosterone into dihydrotestosterone (DHT)

The hair follicles have receptors and in some people have inherited a sensitivity to DHT. DHT will cause the follicles to shrink (miniaturise) Hair will grow back thinner over time making the scalp visible and eventually follicles will shut down completely creating baldness.

Stress significantly accelerates androgenic alopecia. 

Cortisol increases testosterone levels & production leading to conversion of more DHT.

Please read section on Genetic Factors for further information on Androgenic Alopecia.


Trichotillomania (self hair pulling) is a complex psychological disorder in which the sufferer has an irresistible urge to pull out their hair. (This can be from the scalp or any part of the body)

It is a very distressing mental health disorder classified under Obsessive - Compulsive & Related Disorders. 

Hair pulling is triggered or accompanied by several emotional states.

Stress, depression, anxiety, trauma, tension and boredom can trigger the urge which is followed by feelings of relief, gratification or pleasure. These can then be followed by feelings of disgust, self loathing, disappointment which lead to further stress, anxiety, depression and tension, creating a continuous cycle.



Many medications can be attributed to hair loss.  Shedding an excessive amount of club hairs may be a result of  medications as some drugs can cause damage to hair follicles. or interupt the hair growth cycle. 

It is vitally important that if you notice any abnormal hair loss you must not stop taking your medication. Speak to your doctor who may be able to prescribe an alternative medication. 

Here is a list of some medications that are known to cause hair loss as a side effect.  Please read the leaflet included with your medicine which will list known side effects or contact your Health Care Professional for further advise

nutrition & diet


medical conditions

Medical conditions can be directly or indirectly linked to hair loss.

Hair Loss can be a side effect of medications taken to treat the condition or the result of the body unable to absorb vital nutrients necessary for healthy hair growth. 

Alopecia Areata is an autoimmune disease where the immume system mistakenly attacks the hair follicles.

 Autoimmune diseases. 


FRONTAL FIBROSING ALOPECIA (FFA) is  believed to be an auto immune disease although the exact underlying cause is unknown.  It is characterised by hair loss & scarring on the scalp near the forehead.

The area of hair loss on the front & sides is typically symmetrical and slowly progresses over time. 

RHEUMATOID ARTHRITIS Rheumatoid Arthritis 

Can cause body to destroy red blood cells

Medication Disease Modifying Anti Rheumatic Drug (DMARD) Methotrexate used to treat can cause hair loss to 1 in 3 people as it can inhibit cells from growing including the hair follicles.
