Kerastase Genesis Hair Serum – Daily Strengthening Treatment

About this item

Kerastase Genesis Hair Serum is a daily scalp treatment made to cut down on hair fall from breakage during brushing. It's built with ginger, caffeine, and arginine to strengthen weak strands and support healthier-looking density at the roots. The lightweight texture absorbs fully without leaving any residue behind. Best used consistently for 6 weeks or more, and works well alongside the rest of the Genesis range for normal to dry, weakened hair.

• Daily leave-in serum that targets hair fall caused by brushing breakage
• Formulated with ginger and caffeine to boost strength in weak, brittle hair
• Arginine helps support blood flow to hair roots, encouraging fuller-looking density
• Lightweight, no-residue formula — apply to dry or towel-dried scalp in sections, then massage in, no rinse needed
• Use morning or night for at least 6 weeks for visible results
• Pairs with the Genesis line: Bain Nutri-Fortifiant Shampoo, Fondant Renforcateur Conditioner, and Defense Thermique Primer
