Keratin , the main constituent of hair, is a filamentous protein composed of chains of amino acids.

His fame as  powerful rebuilder  It is due to a sulfur-containing amino acid: cystine.

With his  sulfur atoms , gives the keratin chains a tight cohesion, allowing them to wrap around the hair with a structure similar to a helix. It is precisely these bonds, called sulfide bridges, that ensure the  stiffness and solidity to the hair .

There  Keratin strength  of our hair, is threatened daily by  Chemicals  (aggressive shampoos, colouring, bleaching, perms), heat (straighteners, curling irons, hair dryers) and  atmospheric agents  (UV, sea, smog). 

Even the  stress , some drugs and a long list of pathologies can lead to the degradation of the keratin structure of the hair which, once weakened, loses shine, elasticity and resistance.  Since the  hair fiber  It cannot regenerate itself on its own  (it does not have DNA), damage repair can only occur from the outside.

In these cases, it is essential to reconstruct the degraded keratin structures with a keratin bath once or twice a month, depending on the needs: the Reconstruction  HAIR MED with  Keratin R3 .

The reconstruction  HAIR MED, exploiting the repairing properties of collagen and keratin  R3 , restores body, volume and shine to the hair, with effects that last up to  3 weeks .

Try it and you'll never be able to do without it again!
