A 10 fold reduction in shedding is amazing!! I've yet to find anything that reduces my shedding that dramatically.
May I ask which niacin brand & dosage you are using?
A week ago, I started taking Life Extension No-flush Niacin 640mg (Niacin activity without the characteristic flush) but I'm guessing it's too soon to notice any shedding reduction. I'm curious how many weeks before you started to notice reduced shedding with Niacin? Did shedding reduce all at once or did it kind of slowly ramp down?
