Great for HairMakes fine hair look thickersee above.Para mi es bueno como cualquier champú no vi ningún cambio en mi cabello como para diferenciar de otro champuThis product contains sodium laureth sulfate, which is never included in kerastase shampoos, harmful to scalp and hair...not likely it is indeed manufactured by kerastase,I googled the compound, please see below (copied from Nutrafol search on google)."Ammonium Lauryl Sulfate or Sodium Laureth Sulfate (SLES)What are sulfates? Sulfates are very strong detergents that work through a chemical reaction, in which they bind with the sebum on our scalp and with water. When you rinse out the shampoo, sulfates take all the oils and residue with them. But while cleansing, they can also damage the hair, make it brittle, and increase frizz".It is the best shampoo I have ever used in my lifeNot sure if I got a real one or not, but overall not impressed and didn't see or feel any difference almost a month in of using it. Will not buy againI have been buying this shampoo from Amazon for years. This bottle looked and feel different - but I thought “rebranding happens”. Then I tried it. Not the same shampoo. It came from Beautogen.Looking closer bottle color and texture is off - the lid detail is not uniform - in pic you can see on the left it is closer to top than rest of bottle. The label on prior was less obvious as a sticker or wasn’t a sticker at all.This is the best shampoo I've found for my fine hair. I don't need to use a conditioner and it doesn't irritate my scalp, where I've found others make it itch. Its a bit pricier than some but worth it.Definitely does volumise your hair, I was extremely surprised how big your hair actually gets. Only downside, I feel like I need to clean my more than twice a week which is more than when I used to use the orange top Kerastase shampoo.Good value I’ve oily prone hair and it’s the best kerastese I’ve used for it without drying or irritating my scalpProduct made my hair heavy and flat. Sorry, not for me.Nice gentle shampoo which has a lovely smell.
