What is R3 keratin treatment? This is a specific treatment by HAIRMED based on the innovative R3 re-building fluid with a cherry fragrance. This element integrates and leads to the in-depth re-building of the hair, restoring body, thickness and brightness, with an immediate repair effect. Rich with elements beneficial to hair, such as keratin and collagen, it works on the keratin chains found within the hair structure. R3 keratin lends volume to the hair, also protecting it from chemical aggression (colouring, decolouring or perms), heat (irons or hair-dryers) and external and atmospheric agents. As demonstrated by the University of Modena, reconstructions of this type guarantee immediate fullness, softness and brightness, leading to an increase in thickness of 36%! R3 keratin fluid can be used on both fine and thick damaged hair as it does not alter the structure and fixes only the ingredients necessary: therefore, every hair absorbs what it needs, and any excess is removed with rinsing.
