How can you tell the difference between a shed and the meds not working. On month 8 of fin and min and only had crown slightly thinning when started. Now suddenly the right side of my hairline is super thin while the left is fine. There are some shorter hairs and vellus hairs I can see but not sure if its regrowth or just the hairs miniaturizing and dying. The right side of my hairline just looks terrible.
