same thing happens to me. Are you prone to hairloss by any chance? After a heavy androgen cycle, around 2-3 weeks after last doseage... I just shed like crazy. Don't worry, the shedding stops after around 3-4 months. I made myself crazy getting every hair supplement I can find and nothing worked. Finally I researched it and found out what was causing my hairloss. It was from Telogen Effluvium. I let it happen, showered with nioxin and nizoral 1 and 2% EOD. Well, today I don't shed a single hair... Not even one visable in the shower. The hair shedding test (one where you rub your head on top of a white piece of paper and count the hairs that land on it) passes every time I do it, 1 or 2 hairs at most.
All i'm trying to convey here is... if you weren't shedding before cycle and during it.. there's a GREAT chance that its Telogen Effluvium and it WILL grow back.
