Spring Training for Long Hair

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.

With any training program, the goals are strength, stamina and speed. Hair goals aren’t much different. When you’re working on growing your hair long, you want to start off strong at the root and maintain peak form through the mid-lengths, all the way to the ends.

Hair gets longer, faster. It gets better and better every day. There may be times when you want to quit and cut it all off, but with patience and consistent effort, there is simply no limit to the lengths your hair can go.

Kerastase Resistance Extentioniste Healthy Hair

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.

Kerastase Resistance Extentioniste Shampoo + Hair Mask

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!

Repeat and Succeed

This is where the effort really counts. Keep up your at-home strengthening ritual—don’t give up! Consider adding Masque Extentioniste for extra power at the ends—they should match your roots in thickness. Visit your stylist up to once a month for further recommendations and a re-up of Protocole Extentioniste.
