I have fine hair, and I have been using Goldwell color definition shampoo light for fine hair until now, and it has really helped in making my hair manageable as well. However, recently when I went to the local store, the person out there didnât have the Goldwell shampoo, and asked me try shampoo from Phyto. I did not buy it yet, but when I checked the details of Phyto hair products, they seem to be quite nice. I wanted to know from somebody who has used both the brands to tell me the difference whether I should try Phyto hair products for my fine hair, or it would be better to look for Goldwell shampoo at some other store? Please help!
