So this is something that I experience every time I use Mast or Winni. I no longer use winni but with Mast, it's almost a week or two and then I start shedding, scares the shit out of me honestly. I've joked on here multiple times before that I style my hair like movie actor. So that being said, when I know I'm going to use mast, I'll usually start out about 3 months out and use a DHT inhibiting shampoo. The problem with this is is these shampoos and after shower treatments are more effective in long term use. But for me, I can for some reason only use this stuff for about 4-5 months before I get tired of it. I'm getting ready to use mast, actually I'm starting this monday and I use DS Laboratories Spectral-DNC along with there shampoo and hair conditioner. It seems to stop shedding by about 50-60%. So I'll take that over nothing...
