── holiday aftercare ──


At home or abroad

Hair Extensions are a commitment and require additional time dedicated to aftercare. This will ensure your natural hair also remains in healthy condition during wear.  

Following our recommended guidelines will ensure problem free wear and help maintain  the lifespan of your hair extensions and protect & preserve your natural hair.

Firstly you need to understand the elements in water, not solely if you are travelling abroad but also here in the UK and how chemicals and products which react to those elements can cause your extensions to change colour, become dry & brittle, create matting or cause your attachments to break down. 

In a hotter climate or holiday your hair is likely to be exposed to sun & heat, chlorinated pool, sea salt and minerals in the water as well as ingredients in some products you may be using, particularly sunscreens.


aftercare procedure

Here are the guidelines & products we recommend  for trouble free extension wear whilst on holiday or live in a hard water area.

Use the following procedure in addition to your regular aftercare routine:

  • For swimming If possible secure all hair inside a swim cap or:
  • Brush hair thoroughly.  On dry hair spray leave in conditioner or a diluted version of the Malibu C Hard Water Wellness Conditioner into mid lengths & ends avoiding roots & attachments.  
  • Plait hair into one or two plaits as this keeps the hair neatly contained. Pin to the top of the head for swimming.
  • ASAP wash hair using the MalibuC Hard Water Shampoo followed by the Malibu C Hard Water Conditioner.
  • Continue to use all the aftercare techniques specific to your application method 
  • Apply the leave in conditioner & hair oil from your usual aftercare routine
  • Ensure hair is brushed thoroughly
  • Do not tie hair up when wet and leave to dry
  • If leaving to dry naturally always dry the attachments 
  • Once a week use the MalibuC Hard Water Wellness Remedy Sachet
  • Once a week use the MalibuC Miracle Repair or your usual deep conditioning treatment


attachment breakdown

Your attachments are also at higher risk of breakdown due to hard water & chemical exposure, hotter climate and prolonged wet / damp hair and daily washing.


  • Can soften
  • Turn white making them noticeable
  • Crumble
  • Hair can shed from the bond
  • Higher strand loss
  • Applies to - Fusion Bonds / Mini Tips / Nano Rings


  • Green build up from copper oxidisation
  • Paint can peel revealing copper underneath making the attachments noticeable
  • Silicone linings can deteriorate resulting in slippage / strand loss


  • Stitched thread can become brittle and snap
  • Adhesive seal on some weft top designs can break down leading to shedding
  • Weft tops can rot leading to shedding
  • Copper Rings can be effected as above


Tape Extensions are not suitable for clients who regularly swim or exposed to high humidity, hotter climates.

  • Heat can warm the adhesive and lead to slippage.
  • Tapes Extensions should not be shampooed more than 3 times a week
  • Chemicals will cause the Tapes to open
  • Water can penetrate between the Tapes causing slippage 
  • Steam from Hot Tubs & Jacuzzis can cause the Tapes to begin opening
  • Sweat on the scalp can cause the Tapes to open causing slippage.

Hard Water has a higher pH level which can attribute to attachment breakdown. 

Hair Extensions which have an adhesive bond are at the most risk.  

This can be combatted by ensuring the recommended  pH balancing shampoo and conditioner are used to neutralise the effects. 



One of the main causes of matting is hair being tied up when wet or sleeping with wet / damp hair.

The presence of heavy mineral deposits will weigh the hair down, cause it to bunch together when wet, making it tangled and difficult to brush.

It is so important that the hair is thoroughly brushed before putting up and when taken down and washed & dried ASAP after contact with pool / sea water or heavy head sweating. 


hard water

Is your hair being exposed to hard water and other elements causing issues with your hair? 

If you are in the UK you can check the hardness of your water by looking at our Water Hardness Map.

IYou can also purchase water testing kits to use at home or f you are travelling abroad to determine whats hidden in the water your hair will be exposed to.

Hard water contains hidden natural minerals which can be absorbed into the hair through a chemical reaction known as 'Oxidation'

Oxidation put simply is 'the addition of oxygen'

Almost all elements (water, sun or air) react with oxygen to form compounds called Oxides.

A typical example of oxidation is the rusting and corrosion of iron.

In moderate amounts oxidisers can cause discolouration or loss of hair colour. Great amounts will cause it damage and breakage

Oxygen in air & water coupled with heat & light from sun exposure (UVA & UVB light) can accelerate oxidation.

Minerals enter the water by ground or surface water.


Ground water comes from under the ground. Both domestic & community wells derive their water from rain passing through aquifers which are layers of minerals.


Surface water comes from rivers or lakes & usually contains fewer minerals because the water has not filtered down through mineral layers. Unfortunately increasing populations are polluting the water which causes additional bacterial growth. This growth is controlled at treatment facilities by adding Chlorine to kill bacteria & then adding Lime (a claim compound to help control chlorine levels.

The following lists the natural minerals found in Hard Water and what effect they have on the hair when oxidised.

Avobenzone is an ingredient used in most sunscreen products for its ability to absorb full spectrum UVA rays.

It is also found in many other products offering UVA protection such as moisturisers, shampoos, conditioners, foundation, concealers, lip balm, sun protection spray for hair and its even found in perfume. 

Avobenzone in suncream causes discolouration of clothing. White clothes in particular you will notice that horrible pink / orange staining.

When hair comes into contact with Avobenzone and hard water a chemical reaction occurs which causes iron to bind to the hair. 

This will turn blonde hair an orange / pink tone or dark hair duller and darker.

Due to the way hair extensions are processed they are naturally more porous, so the colour change will be visible quicker than in the natural hair.

The reaction will depend on the level of iron present and the amount of exposure, so discolouration may happen gradually over time or instantly. 

It will only occur in the areas that have come into contact with Avobenzone so explains why only the tips of a ponytail experience change as the ends are what brush the shoulders.

Or around the hair line or face where moisturisers, foundations or suncream are applied. Or sunscreens are sprayed on the face.

This image credit to Victoria Lynch, MD of Remi Cachet. The results of physical testing of hair extensions coated in different brand & factor sunscreens and exposed to water from various locations globally. The colour change is distinct between the original colour and the exposed bundle. 

Always check the products you use on your hair do not contain Avobenzone

Avobenzone is also known as:

  • Methoxylphenyl
  • Butylphenylpropane
  • Butylmethoxydibenzolmethane
  • Methoxydibenzoylmethane
  • Parsol1789
  • Milestab 1789
  • Eusolex 9020
  • Escallop  517
  • NeoHelipan 357
  • Dibenzoylmethane 
  • 4-tert-butyl-4-methoxydibenzoylmethane
  • BMDBM cod
  • 70356-09-1
  • 1-(4-tert-butylphenyl)-3-(4-methoxyphenyl)propane-1,3-dione
  • 4-tert-Butyl-4'-methoxy-dibenzoylmethane
  • 1,3-Propanedione, 1-(4-(1,1-dimethylethyl)phenyl)-3-( 4-methoxyphenyl)-
  • DB094595


This is also used in sunscreens and usually paired with Avobenzone. 

It is also a major factor in discolouration of hair extensions due  to a chemical process that occurs when it absorbs UV rays. It is only safe for use if there is less than 10% in the sunscreen formula.

The higher the amount in sunscreen the  higher a chance of discolouration through iron absorption.

Octocryline is also known as:

  • Octorilene
  • Uvinul N - 539


scientific study

In 2015 Abigail and Victoria Lynch, (Managing Director of Remi Cachet) flew to Las Vegas to a trade show.

Discolouration of blonde hair extensions was widely reported by hair extension professionals around the world. It was occurring with several different brands.

Determined to establish the exact cause and to find a remedy,  hair testing and a long academic study began. 

It was here the connection to sunscreen and the presence of Avobenzone was made.

Abigail began the theory and study of the scientific causes through chemical processes.

She also began testing hair in which discolouration had occurred for ways to treat & effectively remove the pink / orange tone.

In early 2016 their early findings were released and the recommendation of the MalibuC products was launched as an effective product in the prevention and rectification of discoloured hair extensions.

This is now common knowledge throughout the industry.

In continuation of this study, Victoria took bundles of blonde extensions and began exposing them to elements associated with holidays. 

These physical tests continued in several locations worldwide.

She documented each exposure, the brands of sunscreen used &  their SPF ratings.

These were exposed to different water sources and the water was tested for the elements it contained.

The degree of discolouration, the timescale it took to occur etc were all documented and the results relayed to Abigail to establish all the links.

In 2019 Abigail wrote a Harvard referenced scientific study which established the exact cause & chemical processes attributed to the discolouration of blonde extensions.

It was revealed to all Remi Cachet SuperStylists.  Each signed a Non Disclosure Agreement and the report has never been released to the public.



Iron is usually found in well water and in areas that have concentrations of iron in the ground.

Iron will slowly cause hair to tint darker, add weight to the hair & prevent proper chemical processing (hair colouring, perming & relaxing)

Heavy amounts of iron will tint light coloured hair orange and cause darker hair to become darker with red highlights.

In this image (sideways view) you can see the discolouration through the mid lengths and ends of the hair. This is a common area for hair discolouration. When the hair is tied up it brushes the shoulders coming into contact with sunscreen on the shoulders and back of the neck. When exposed to hard water the chemical reaction occurs resulting in the iron deposits reflecting their colour (orange)



Copperl bonds strongly to the hair and originates from either ground water, particles from copper pipes or most commonly copper sulphates added to pool & drinking water to control algae growth. Oxidised copper discolours light hair, producing a green tint and causes dark hair to tint darker.  

Our Ultra Locks, Mini Locks, Nano rings & Micro Rings are all made from copper and coated in paint.

When these are regularly left  in a damp environment a green reside begins to form on the lock / ring. This is a perfect physical example of oxidation. The constant moisture over a prolonged period of time, once in contact with the oxygen in the air causes oxidation to occur.

Oxidation of copper produces 'Verdigris' 

a natural patina that forms. This can be seen on the copper water pipes throughout your home. Perfect example is all over The Statue of Liberty.



Calcium is the mineral in most all water but is greatly found throughout the United States.

Mineralised calcium is also naturally found in the ground, especially where limestone is present.

Calcium will build up on the hair leaving it feeling dry and weighted down. 

Calcium salts build up on the scalp & cause flaking, often recognised as dandruff.. These deposits are much like the ring that forms around the bath associated with hard water & soap.

Hard water makes shampoo less effective (remember the bottle image) Leaving build up and residue on the scalp. 

A build up of calcium on the scalp can clog the hair follicle causing hair to break off, Heavy clogging can inhibit hair growth.


Desalinated water is used in many places of the world but is most common in the Middle East & the Arabian Gulf. (Saudis Arabia, Kuwait, United Arab Emirates, Qatar & Bahrain) 

Desalination is the procedure of of eliminating salt from seawater to produce drinking water.

Sea pollution causes contamination and additional bacterial growth.

The processing plants purify the water by adding higher levels of chlorine to kill the bacteria & then add lime (which is a calcium compound) to assist with controlling the chlorine levels.

So if you are travelling to any location that uses desalinated water bare in mind the water you are washing your hair with will have higher levels of chlorine and if you are also swimming in pool water this will have additional chlorine.

Magnesium is abundant in the soil.

Calcium and Magnesium are the two most common minerals that make water "hard"   Water hardness becomes greater when the level of Calcium and Magnesium content increases.  The effect on the hair is due to to the concentration of positively charged ions allowing it to attach to the hair.leaving it dry and weighted down.

Further information on the effects of Magnesium can be found our EXCLUSIVE ACCESS page



Chlorine is the main chemical additive which is added to water. Primarily these which are designed to purify the water & kill bacteria.

  • Chlorine is an active bleach which is used to remove pigment in colour.
  • Will damage the cuticle & internal proteins creating an oxidising effect on elements in the hair
  • Chlorine alters the electric charge on minerals causing them  bond to the hair
  • Can change colour of certain minerals
  • Highly charged minerals damage  & discolour the hair, usually and commonly green, particularly noticeable on blonde hair
  • When Chlorine comes into contact with copper in the water it creates a chemical reaction called *Oxidation'  which causes the metal to bond to the hair. Depending on the level of copper colour change made be rapid or gradual build up over time.
  • Active chlorine will leave the hair feeling 'gummy' when wet & straw like when dry
  • Regular exposure will leave the hair dry, brittle and prone to breakage


Bromine is sometimes used as a substitute for Chlorine. This will react with the cuticle,  the natural layer protecting the internal proteins within the hair, leaving it exposed to mineral absorption 



Salt is highly present in sea water, the most prominent is Sodium Chloride (which is table salt)  chlorine, suphur, magnesium, potassium  & calcium.

The water content of your hair its what makes it stretchy and moisturised. 

Salt (Sodium) is osmotic , which means it will draw the moisture from your hair leaving it dry & brittle. 

Sweat is mainly made of water & electrolytes (sodium & choride) 

In hotter climates your body will sweat more naturally.

Salt leads to the breakdown of keratin hair extension bonds if excessively exposed.

Salt is Hygroscopic.  It attracts water to your hair creating salt crystals, this in turn draws moisture from inside the hair strand. causing dehydration.  making it more fragile and prone to breakage. 

Further Information on the effects of salt can be found on our  EXCLUSIVE ACCESS page



Silica is a sand like substance found in areas of volcanic or desert like areas. It is usually bound to calcium & magnesium & forms very hard, virtually insoluble deposits on surfaces. 

Waterborne Silica can build up on the hair causing the same effects as calcium. - dryness, stiffness, dandruff weigh the hair down. 

Further information on Silica can be found on our EXCLUSIVE ACCESS page


ph levels

The pH balance of the hair and the water it is exposed to will have a great impact. 

If the products used or water is too alkaline this will cause the cuticle (the outer layer) to open. This will enable mineral deposits to easily penetrate and be absorbed. 

If products used following mineral exposure are too acidic the cuticle will close, sealing the mineral deposits making them difficult to remove.

Hard water is high in pH alkaline.

Hard Water discolouration due to mineral deposits is different to colour fade.

The high pH imbalance causes the cuticle to raise, thus resulting in faster colour fade allowing the colour to stripped from the hair faster.

Also the use of '"No Tears" formula childrens / baby shampoo will accelerate colour fade as these have a higher pH level . This will accelerate colour fade as these have a high pH 

A raised cuticle due to high pH will be roughened and also prone to matting.

Further information on the effects of pH levels can be found on our EXCLUSIVE ACCESS page


water softeners

Water softeners remove calcium, magnesium, iron and metals present in hard water. As well as removing positively charged ions.

There are many shower head filters on the market which are a great investment for very little cost. We recommend one that filters Chlorine & Heavy Metals.
