"I found a shampoo I like so much, I'm telling everybody I know about it. It's called "Thicker Fuller Hair", and it's probably the first "thickening" shampoo I've ever used that really worked. My hair is probably medium thin, but it's kind of limp. This shampoo really gave me body, I could see the difference as soon as I blow dried my hair. The label says it expands the hair shaft, but whatever it does, it makes my hair look a lot better. I've paid way more for shampoos in the beauty supply stores and gotten no results. Try it and tell me what you think."
