Close Up of Cylinder Hair Extension Bond

fully customisable bonds

The Tips are made of a completely safe keratin designed specifically for hair. The strands have the bond already attached eliminating the need for messy glue guns.

Each bond can be custom sized to match the weight of the natural hair it is being applied to. 

Different colours can be fused together to create a perfect, tailored colour blend & match.

The bonds can be customised into a Cylinder Bond or a Flat bond. The cylinder bonds shown here resemble a tiny grain of rice.

The Flat Bond lies entirely flat & cant be felt even when running a flat palm down the back of the head.  Flat bonds have a slightly less life span than a Cylinder Bond.

how are fusion bonds fitted?

A small section of the natural hair is selected. The keratin tip is placed under the hair.  A heat application tool which resembles a very small thin pair of hair straighteners is used to melt the keratin through the hair. . Then the bond is hand formed and sealed.  Fusion Bonds are applied in neat rows 1.5cm from the scalp to allow the natural hair to move freely without tension.

during wear / hair growth

Your natural hair will continue to grow whilst wearing Fusion Bonds.  The rate of growth will vary client to client.  Your hair will also continue its natural shedding cycle.  The hairs which would usually be found in your hair brush or plughole will remain trapped inside the lock. These shed hairs can be recognised as loose unmatched sprouts of hair with little white dots on them.

This is NORMAL and no cause for alarm. 

We strongly recommend a maintenance appointment to trim away shed hair to prevent matting as bonds are worn longer due to their customisable weight & size.

Fusion Bonds take longer to remove.  The bond is broken down by crushing with a set of special removal pliers and an alcohol based removal solution. Once the bond has been broken down The extension can be gently guided out.

The build up of natural shed hair is gently teased apart & brushed out.  (Some will remain fused inside the removed strands)

The amount of shed hair will vary person to person. It can appear to be a large amount but this is 12 -20 weeks worth of hair which would have naturally fallen. If collected the hair from your hair brush over the same period you would be surprised at the amount. 

Your hair may feel thinner as you will have become accustomed to the extra volume & weight of the added extension hair., so may take a little while to adjust. This is also normal & it will be exactly as it was prior to extension wear .  We monitor the natural hair at refits to ensure there are no adverse changes.

All hair we use is completely reusable (with the exception of our lower priced range which is more cost effective to replace)  

The Fusion bonds require new bonds before they can be refitted.  We outsource our retipping so the hair is sent away and cant be refitted the same day.

Some clients prefer to have a second set to rotate so there is always hair to refit on the same day. 

The Fusion Bonds are worn for up to 3 months in very fine hair, 5-6 months for classic cylinder bonds and 4-5 months for flat bonds.
