Kérastase Resistance Sérum Extentioniste is a highly concentrated serum with key active ingredients that stimulate the growth of strong healthy hair follicles. This energising leave-in treatment is a key step to reinforce roots and promote a healthy scalp environment. Its non-greasy formula harnesses the power of ceramides to protect the scalp from environmental aggressors while stimulating and energising roots. Applied with a gentle scalp massage, it is ideal to boost and activate the growth of healthy hair to achieve strong long hair.  


Give your hair a second life. Kérastase Résistance rebuilds the internal substance of hair weakened by chemical or mechanical agressions to restore its strength and solidity. Force Architecte is dedicated for damaged hair (erosion level 1-2), while Thérapiste (erosion level 3-4) is designed for very damaged and over-processed hair. Hair is restored and the quality of the fibre is like new.


Apply a maximum of 3 pipettes of Sérum Extentioniste along key sections of the scalp, once or twice a week. Using the pads of the fingers, work the Sérum into the scalp, using circular motions.

A skin patch test before use is recommended.
