So far, this is my new favorite shampoo. I was using Head and Shoulders Thickening shampoo before but after reading a lot of positive remarks about this PATRICKS SH1 Daily Thickening Shampoo, I decided to purchase and try it for myself. I have an oily and thinning hair. It's maybe due to hair rebonds and straighteners that used in my hair. And this shampoo cleans my hair thoroughly and really improves the thickening appearance of my hair. I can really say that it works and there's a big difference between before and my current hair condition. I recommend it to people who have thinning hair too. Try it and you will really notice the difference. You will also like it like I do! :-)
