Damage Rescue Kit

Where should I start if my hair is damaged?
Start with a shampoo and conditioner or mask from one repair range, then add a leave-in. For lightened, fragile hair, L'Oréal Absolut Repair Molecular is a strong base. For brittle, snapping lengths, try Kérastase Résistance. Our damaged ends guide explains what products can and can't fix, and when a trim is the better call.

Can I mix brands in a damage routine?
Yes. We do it in the salon all the time. A common combination is a repair shampoo and mask from one range, plus a heat protector or leave-in from another, like Kérastase Ciment Thermique before blow-drying. The thing to avoid is stacking too many heavy products at once, which can leave hair limp.

What's the best option for damaged blonde hair?
Pureology Strength Cure Blonde Purple Shampoo and Strength Cure Blonde Conditioner repair and tone together, so they suit lightened hair that's both brassy and fragile. Use the purple shampoo every second or third wash with the regular Strength Cure Shampoo in between. Our damaged and bleached hair guide has more options.

What does Kérastase Nutritive 8HR Night Repair do?
It's an overnight treatment. Apply it to dry or towel-dried lengths before bed and leave it in, so your hair gets conditioning while you sleep without having to wash it out. It suits dry, damaged ends that need more than a daily leave-in. Keep it away from the roots if your hair is fine.

Do I need a heat protector if my hair is damaged?
Yes. Damaged hair has less protection of its own, so heat from dryers and straighteners does more harm. Kérastase Resistance Ciment Thermique goes on damp hair before blow-drying. Use a temperature you can work with rather than the highest setting. If you style daily, protector every time makes a real difference.
