Itchy flaky scalp hair loss

[PatriotKid]

I have had a really itchy scalp for about a month now. During work and in the middle of the night. Eversince i started using Biotene Shampoo (biotin) I think that's the cause. My hair falls out when I shower, on my pillow, and work desk. But no more than 50 all together. Any suggestions on how to cure my itchy flaky scalp? And yes I'm thinning/balding at the top but hairline is deccent. Help.

Hey yeah I just realize that I stop running on the treadmill and power walk instead that's when the itchiness happen. I'm lifting a lot more weights because I'm trying to build mass and was suggested by my muscular friend to power walk instead. So me running wont happen on a daily basis, maybe once every other week because I can easily drop pounds. I might have to try some natural remedies to cure the itchy and flaky scalp of mines
