If you want to keep hair loss at a minimal level and cycle steroids, avoid such strong androgens, as winstrol, trenbolone and deca. The above mentioned N2Shampoo is really good as well. If the hairloss has already started, a product called Vichy Decros Neogenic is extremely helpful to recover hair growth. Regarding the Biotin - never heard of it as an efficient way of reducing hairloss.
