Deep restorative effects

• Hair is genuinely repaired from the inside out, thanks to a complex of active ingredients that start working at the heart of the hair fibre to restore the bonds between keratin chains. The hair fibre is strengthened and restored, for stronger, more resistant, healthier hair.

• On the outside: the complex of active ingredients seals the scales, sheathes the hair fibre and prevents the appearance of split ends.

• Hair is immediately, lastingly and deeply moisturised thanks to hyaluronic acid.

Result: an overall improvement in the appearance of the hair

• Your hair is restored right down to the tips, split ends are reduced and each strand of hair is sheathed.

• Hair is shinier, glossier, softer and silkier.

• All hair types are improved.

• Ideal for looking after long hair.

The shaft consists of 3 layers:

The cuticle: the cuticle is the name given to the outer layer of the hair. It is made up of flat, scale-like cells that overlap to form a protective covering for the hair shaft. A healthy cuticle has sealed scales and is smooth to the touch. It is the cuticle that gives hair its shine. It also helps lock optimal moisture into the hair.

The cortex: this is the intermediate layer and main component of the hair shaft. The cortex contains long cells made up of helical chains of keratin. These chains are joined by thousands of bonds called 'disulphide bridges'. These capillary connections between keratin fibres give hair its texture, suppleness and strength. It is also in the cortex that the melanin pigments responsible for hair colour are found.

The medulla: at the core of the hair we find the medulla. There is keratin here in the form of loosely packed cells forming an amorphous, soft, greasy substance. The medulla contains amino acids and sugars, such as glycogen.
