KÉRASTASE Genesis Hair Serum — Lightweight Anti-Breakage Scalp Treatment, 3.04 fl oz (Ginger & Caffeine)

KÉRASTASE Genesis Hair Serum is a lightweight, silicone-free daily scalp serum formulated to anchor hair and reduce hair fall from brushing while strengthening fragile strands.

This concentrated fortifying serum from the KÉRASTASE Genesis line is designed to reinforce weakened hair from the root and lower the amount of hair lost during brushing. Enriched with ginger extract, caffeine, and arginine, the non-greasy formula absorbs quickly without residue and can be applied directly where density is thinner. Clinical testing with users reported up to 97% less hair fall from breakage due to brushing when used as directed.

How does this serum reduce hair fall from brushing?

The serum targets the scalp and hair fiber to strengthen strands at the root and along the shaft, which decreases breakage when hair is combed or brushed. Key actives work together to help reinforce the bond between hair and scalp without weighing hair down.

• Ginger extract and caffeine help energize and support scalp microenvironment.
• Arginine supports local circulation to nourish hair roots.
• Lightweight, silicone-free texture avoids buildup that can make hair break more easily.

When and how should I apply the serum for best results?

Apply daily in the morning or evening to dry or towel-dried scalp, focusing by sections for even coverage. A minimum regimen of six weeks is recommended to see measurable reduction in breakage from brushing.

• Use four doses per application, sectioning hair for direct scalp placement.
• Massage gently to distribute product and improve absorption; do not rinse.
• For spot treatment, target areas that appear less dense to strengthen locally.

Will this serum feel heavy or leave residue on my hair?

No — the Genesis Hair Serum is formulated to be lightweight and non-greasy so it won’t leave a heavy film. It’s designed to fortify strands while maintaining natural movement and texture.

• Silicone-free formulation reduces buildup risk.
• Fast-absorbing base leaves hair touchable and natural-looking.
• Works under styling products and heat protection without interference.

Can I use this with other KÉRASTASE Genesis products?

Yes. For a comprehensive approach to reduced breakage and healthier-looking hair, combine the serum with Genesis Bain Nutri-Fortifiant shampoo, Fondant Renforcateur conditioner, and Defense Thermique primer. Together they target both scalp strength and fiber resistance.

• Cleanse with Bain Nutri-Fortifiant to prepare the scalp and fiber.
• Condition with Fondant Renforcateur to detangle and reinforce strands.
• Use Defense Thermique before heat styling to protect fragile hair.

Who is this product for? The KÉRASTASE Genesis Hair Serum is aimed at people with normal to dry, weakened hair that tends to break during brushing. It’s suitable for anyone seeking a targeted, easy-to-use daily treatment to strengthen hair from the scalp outward, especially where density feels reduced. If you want a light, non-sticky serum to anchor strands and help lower breakage without changing your styling routine, this formula is geared toward that purpose.
