I started finasteride a week ago exactly. I took only 1/2 dose the first 4 days and then I began with 1mg thereafter... I'm starting to notice some shedding right now... last month I underwent DRASTIC shedding and thinning which prompted me to take action. Can the shedding I'm experiencing now be due to finasteride or is it still probably my natural hairloss advancing itself even more??? Also I think the sides and back are shedding hair too if that matters... I feel like the sides and back of my hair have also thinned compared to my younger days, though not bald-level thinning.
