This strengthening hair mask intensely hydrates weakened hair to address hair fall caused by breakage from brushing. Recommended by professional stylists to fortify all hair types, its creamy formula moisturizes and softens hair. Fragrance Description: The bright, invigorating scent unfolds with top notes of bergamot zest, cedrat, and lime; base notes of basil, bergamot flower, and rose; and base notes of vetiver, musk, and tonka bean. Clinical Results: In a controlled study, vs. a non-conditioning shampoo, results showed: - 99% less hair fall due to breakage from brushing - 89% smoother, more conditioned hair.

  • Kerastase Shampoo and Conditioner
I’ve been using this shampoo and conditioner for a few weeks now, and I’m very impressed. My hair feels cleaner, softer, and much more manageable. It doesn’t leave my hair heavy or greasy, and the scent is light and pleasant. I’ve noticed less frizz and more shine since I started using it. Definitely a great product and I will continue to repurchase!💖💖💖💖 ... show more

  • Love this hair mask so much!
I bought the whole kerastase line for hair loss and breakage prevention. This works great! Need to leave it on for about 5 minutes and after that my hair feels smooth and healthy again. I use it about once a week or so. Smell great! Feels great and u can see a difference. Controls my frizziness and hair feels healthy. I know it tends to be more expensive but I think it’s totally worth it! ... show more

  • expensive but works
like butter to your hair (great for severely damaged dry hair with split ends from bleaching or frequent pool use) u just leave it in instead of your conditioner for 5' and then u wash it off. even better results when I don't use the hairdryer and let my hair air-dry.
