Résistance Sérum Extentioniste by Kérastase is a highly concentrated scalp serum with selected ingredients that stimulate hair follicle growth. The non-greasy formula of the leave-in serum harnesses the power of ceramides to protect the scalp from environmental factors. Applied with an invigorating scalp massage, it stimulates hair growth at the root for stronger and longer hair.

How to use

  1. After washing your hair, apply 2–3 pipettes of Sérum Extentioniste to the scalp 1–2 times a week.
  2. Massage the hair roots in circular motions with your fingertips to distribute the serum and ensure its deep penetration.

The slow, circular, and gentle movements have a relaxing effect, while fast and vigorous massage imparts energy.
