Hi everyone. Long story short, went from NW1-ish to what looks like NW2-2,5 in a year or two. Currently 22 going into 23. Need advice concerning finasteride. Started it 4 months ago. No sides. Shedding went from 4-5 hairs to litterally hair everywhere, 10-15 in the shower, 15-20 when shaking hair, hair on pillow. Had what seems like vellus before but cannot seem to know if it has gotten better or worse. Also, head started itching about a month after staring, while it never itched before. So, what should I do?
