Brand New
Kerastase Extentioniste

With any training program, the goals are strength, stamina and speed. Hair goals aren’t much different. Start your program to your hair in the best shape of your life. Watch as it grows longer in better shape with the right at-home routine and powerful salon boosters.

Day 1: The Warm-Up

Jumpstart your progress! Visit your Kérastase stylist (a.k.a. your hair coach) for the Extentioniste Treatment Service, an intensive treatment that will provide 99% less breakage* and 78% less split ends*. Request Serum Extentioniste for scalp activation. Strength begins at the root, and you want to set yourself up for success.

**After one application of the routine: Bain Extentioniste + Soin N°1 + Soin N°2 + Sérum Thérapiste vs. non-conditioning shampoo.

Weeks 1-4: Game On

It’s go time… repeat your daily mantra: long and strong. Continue your growth program with the Extentioniste at-home routine: Cleanse with Bain Extentioniste and condition with Fondant Extentioniste or Masque Extentioniste, based on your stylist’s recommendation.

These formulas contain Creatine R, an amino acid that strengthens the fibers from within. Add your own dose of Serum Extentioniste once or twice a week to re-activate the scalp and aid in fortifying the fibers. You’re on your way to your strongest, most beautiful hair ever!

3 Months: Your Moment of Glory

Hardcore dedication pays off! After three months of training, your hair exhibits up to 4cm more length and is stronger and healthier than ever. Keep going! With exceptional care, there is no limit to the length you can achieve.
