Bio Keratin Thinckening Shampoo 33.8 fl oz

This shampoo makes my usually limp hair have body and hold together very well. It is rather expensive, but my last bottle lasted much longer than I could have expected. So in the long run it is a good buy. It does much better than I would expect a shampoo to do, especially with the use of the BioKeratin conditioner. I would not purchase the shampoo by itself, because I'm afraid I wouldn't get the same results. I get both and I'm well satisfied.
