SERUM EXTENTIONISTE



The Serum Extentioniste by Kerastase is a strengthening scalp and hair serum for damaged hair that promotes healthy hair growth. This energizing leave-in treatment reinforces the hair by strengthening the hair fiber from roots to ends. 

Apply 2-4 drops directly to the scalp on washed, towel-dried hair. To ensure proper distribution of the serum, section the hair while applying the drops. Massage the scalp and the roots gently, then comb the hair through. Follow with your favorite leave-in product, blow dry, style and enjoy the results!

Together with the Bain, Fondant and Mask Extenioniste, the Resistance Extentioniste line by Kerastase promotes hair growth for damaged hair.
