Genesis Anti-Breakage Fortifying Hair Serum
The Kerastase Genesis Anti-Breakage Fortifying Hair Serum is meticulously formulated to combat hair fall and breakage, especially during brushing. This serum is an ideal choice for those with weakened hair prone to falling, providing a robust defence against the common woes of hair breakage. Enriched with a potent blend of Aminexil, Edelweiss Native Cells, and Ginger Root, the serum's jelly-like texture ensures easy application and absorption.
A standout feature of this fortifying serum is its ability to re-anchor hair fibres at the root. This process not only strengthens the hair but also enhances scalp resistance, thereby significantly reducing hair fall and shedding. The serum's efficacy is most notable over a 6-week period, during which it works to bolster resistance at the scalp level. This prolonged application results in visibly stronger, healthier hair, with reduced incidents of hair fall.
How To Use Kerastase Genesis Anti-Breakage Fortifying Hair Serum
Apply four doses of the anti-breakage hair serum to dry or towel-dried hair section by section (one dose is equivalent to one pipette). Massage gently into the scalp and leave in, no need to rinse. Repeat application once daily for 6 weeks, using the fortifying serum morning or night. Follow with the Genesis Anti-Hair Fall Heat Protectant Spray and style as desired.
