Strengthen and protect & grow strands with the Kérastase Resistance Serum Extentioniste, a nourishing leave-in hair serum that helps to protect against breakage. The non-greasy formula uses a host of powerful ceramides to seal the hair cuticle whilst a blend of lipids creates a smooth surface, creating a fortifying effect from the inside out.
The highly concentrated serum forms a defensive barrier over the scalp to protect against damaging environmental aggressors, whilst also sweeping away impurities for a fresh appearance. Hair will be boosted, revitalised and given improved resistance.
 
 
 
 
Apply maximum 3 pipettes of Serum Extentioniste along all the scalp, once or twice a week. Using the tips of the fingers, work the Serum into the scalp, using circular motions. Use 2-3 times a week
