If you think your hair is so damaged, the only option is to chop it all off, then Kérastase Résistance Thérapiste might just be the lifesaver you're looking for. Designed to give over-processed hair a second life, think of this as an emergency resuscitation. The range uses a powerful complex called Fibre-KAP to replace the missing Keratin Associate Proteins (KAP) that your hair structure needs to be healthy and strong. 

The Résistance Thérapiste line is elegant but effective. Start your routine with Soin Premier Thérapiste a pre-shampoo conditioning treatment, before moving on to the Bain Thérapiste, a balm-like shampoo that repairs the hair while you cleanse. If you have thick hair that needs extra help, indulge in the Masque Thérapiste which is dubbed a bandage for voluminous tresses. Finally, make sure you treat your locks with the Sérum Thérapiste. Designed for both fine and thick hair, this consists of a repairing cream and binding serum that protects against heat damage and helps seal split ends.
