The Extentioniste range from Kérastase extentioniste range is designed for beautiful lengths. Beautiful hair from root to tip requires special care and the right products. Over time, hair tends to lose its natural protection. It's because everything starts at the scalp that Kérastase has developed the Extentionist Serum, a concentrated treatment that acts on both lengths and hair growth.

Extentionist Serum activates hair growth and strengthens roots. With a healthy scalp, your hair grows stronger and more beautiful. 

Enriched with ceramides, the Extentionist Serum from Kérastase extentionist Serum cares for the hair fiber and restores the cuticle. Repaired, the fiber is stronger and can fight off external aggressions. Gone are the days of brittle, coarse lengths, and your hair is back in shape. 

Suitable for thick and fine hair alike, Extentionist Serum doesn't grease the roots. Its light texture is pleasant to apply and its pipette bottle makes it easy to dose the right amount of product.

The Extentioniste range from Kérastase extentioniste range offers a complete solution to the challenges faced by damaged, over-stressed hair. This customized hair care routine helps you achieve longer, more beautiful, stronger hair. For example, to nourish split or brittle ends, the Extensionist Bath and Extensionist Mask are ideal. They repair damaged hair and stimulate healthy regrowth. Combined with Extentionist Serum, they optimize results. Show less
