Actually from my personal experience fina and winny were very easy on my hair, while test was not. Of course when I last used test. I didn't use a 5-alpha reductase inhibitor like finasteride. But from my past winny and tren cycles I lost no hair at all. I do beleive though that each person is different in regard to what type of gear predisposes them most to hairloss, although nothing is worse for your hair than test. with no 5-alpha reductase inhibitor.
