Kerastase Chronologiste Revitalizing Youth Shampoo/Baine brings your hair back to life! It helps to strengthen hair that's been weakened by signs of aging. Revitalizing hair by strengthening, nourishing and moisturizing. Lathers super well while gently removing any and all impurities from scalp. Has an amazing scent that I can only identify as maybe a warm amber. I have long hair and it didn't take much to cover the entirety of it. This is the type of luxurious shampoo you'd get at a salon except this is in the luxury of your own shower! Definitely worth the price after you see and feel the drastic difference in your hair and scalp!
