If saw palmetto works for hair loss, would it work better topically rubbed into the scalp? I read an article online that mentioned that and said it might be more effective that way.
I have no idea if saw palmetto even works when taken orally to treat hair loss, as there is much controversy on this. Going through the skin is even less scientific and so really, your guess is as good as mine. In fact, I’m probably the wrong person to ask about this. Perhaps an herbal specialist would be able to tackle it better, though even then, take that advice with a grain of salt.
