Because my older brother is suffering from thinning hair and hair loss, I wanted to buy some shampoo for him that would help his hair grow and get stronger. One of my fellow cosmetology students told me about this great shampoo that she had bought for her boyfriend and said that it worked really well. When I saw the bottle of the shampoo and read all about it I decided to get some for my brother and see if he liked it. After he used it for some time, he told me that he really liked it and thought that it was helping him. Now his hair looks fuller, softer, and healthier. I recommend REDKEN's densify shampoo for anyone that is suffering from hair loss or thinning hair. It works well and you will feel better about treating your hair well.
