Sérum Extensioniste

Kérastase Paris Sérum Extensioniste is a strengthening scalp and hair serum. It is formulated with ceramides to help restore and protect the fibre’s cuticle as it grows. Use once or twice a week by applying two or three pipettes along the scalp on dry or wet hair, following the Bain and Fondant. Using finger tips, work the serum into the scalp using circular motions. Do not rinse.
