My hair has always been thin, but it got a lot worse recently. Shedding tons right now. I shaved it all off and initially for the first 2-3 months my hairs were quite dark and thick (obviously because they were very short, too). Once they became a bit longer and I used shampoo more often, rapid shedding and thinning started. I also noticed i have very dry scalp and if I scratch a bit, there's scales and flakes coming off. Did you have that issue, too? When using Nizoral, my scalp gets even drier and my hair becomes brittle.
