There is a subreddit dedicated to hair loss and techniques. I think one of the highly rated posts discusses use of weekly dermarolling, massaging the scalp, in combination with the regular things like finasteride, minoxidil, and ketoconazole shampoo. Anyways, this isn't exactly science. I think one mode of action to explore is increased blood flow helping with hair growth.

We know massaging an area increases blood flow to that area, in turn promoting better cellular metabolic processes. Dermarolling seems to do this through inflicted trauma/irritation to said area. I know one of the actions of minoxidil is a vasodilator.

Checks out. Worst case you just have really clean hair and developed a new daily mindfulness technique.
