"My son has been using a combination of the shampoo and conditioner in an attempt to thicken his hair. It does appear thicker and healthier after four weeks of use. He is going to try it for a longer period to see how much thicker it can get." - Tami Qualls
"After the first couple of uses, I was happy to find it working: hair felt lighter and more voluminous. However, as is a common problem with fine hair, the 'cleansing' of the shampoo caused it to knot up terribly during washing. And the matching conditioner isn't conditioning enough to smooth it out. I had to stop after two weeks, the knotting got so bad. " - Carla Howe
"I will never use any other shampoo. I have long curly hair and, this Thin-to-Thick shampoo gives my hair a lot of volume. I also use their volumizing spray which I highly recommend. It's great. I LOVE IT." - Anonymous
"My husband says this look expensive. I told him it wasn't. I read a low review on this product was told it was not worth it. But I brought it right away because I like it at sight. The shampoo and conditioner feel light. Leaves my hair soft. The serum is not greasy. I am not expecting wonders because there are a lot of of hair products that claim they can make your hair grow but it does not mean the product is useless." - Carmanita Gonzales
