Collistar Pure Active Filler Phyto Keratin Intensive Restructuring for Damaged Hair 100ml

Why use a pre-shampoo?
In addition to the high concentration of active ingredients present in this type of formulation, the use of a filler before shampooing on damp hair allows the actives to penetrate deeply.
Wetting the hair before applying the treatment allows the cuticles to lift, favoring the penetration of the actives, and a 10-minute exposure time allows the actives to act effectively.
The exposure time and frequency of use of this type of treatment also depend on the type of damage the hair has suffered.
