Exceptional hair knows no limits. Extend your hair limits with our first 90 day hair program designed to optimise and reinforce the length of damaged hair.

Thanks to a new and unique understanding of the science of long hair, Kérastase recognises that long hair needs personalised training to go the distance. Resistance Extentioniste is a daily hair training program, which helps to strengthen hair from root to tip, to help you reach your hair goal.

For over 20 years, Kérastase Resistance has been helping to repair the irreparable. Offering a full range of customised products to rebuild weak and over-processed hair, including the iconic Resistance Force Architecte and Resistance Thérapiste rituals. Now, thanks to the exclusive Creatine R™ complex, Kérastase goes to new lengths, creating Resistance Extentioniste – a hair care range specifically designed to help solve long hair needs and provide the ultimate in hair endurance.
