I a 53 yyrs old man and I didn't have hair on top of my head

I've been using this shampoo for about two months now. I have very fine hair. After the first use I could tell the texture of my hair had definitely changed. The hair seems much thicker and has more body. Overall this was the most dramatic change I've seen with a shampoo which claimed to thicken hair. I can see myself using this shampoo for the long run.
