Liquid niacin used topically?

[Guest guest]

Hi All,

I once had a healthcare provider tell me that, when applied topically, niacin

has been proven to help increase the rate of hair growth since it increases

blood circulation to the scalp. As hair loss is a concern for me, I was

wondering if there was any truth to this, or if any harm could be done by

applying niacin topically to the scalp.

Thanks!
