I really love this shampoo from Phyto. I can truly say it has helped my hair become stronger and it doesn't break off as it use to. I have my hair colored on a regular basis and it is very long so it is trimmed quite often. My stylist has noticed a difference so I am very happy. I use mostly Phyto products and my hair is in pretty good shape for my 66 years. The shampoo is kind of pricey but it seems to last me as I don't shampoo every day. I would totally recommend this.
