Kérastase Hair Serums FAQs

Which Kérastase Serum should I use

Kérastase offers a range of serums tailored to different hair needs. For dry or damaged hair, the Nutritive range provides deep nourishment and hydration. If you’re dealing with hair fall or breakage, the Genesis serum strengthens and fortifies your strands. For dandruff-prone scalps, the Symbiose serum soothes and reduces flakes. Consider your hair type and concerns to find the perfect match for healthier, stronger hair.

How to apply a Kérastase Hair Serum

Apply your chosen serum to clean, towel-dried hair or directly onto your scalp, depending on the product’s instructions. Use a small amount and distribute evenly through your strands or massage gently into your scalp. Leave it in without rinsing to let it work its magic. For best results, use consistently as part of your routine and follow with heat styling if required for added protection.
