Best Shampoo for thinning hair????

[BubbaL]

Hi, guys im currently treating with my hair loss with minox, finasteride, and biotin. so for no improvement over a year. But possibly not any worse?? I really cant tell.

Anyways i was wondering if you guys know of any shampoos you had luck with. im thinking maybe i have a oily scalp and that may be a factor in my hair loss.
