Anyone using DUT as a topical?

Topicals for hair loss
1

Hi- I know a couple of guys here are using or used DUT topically…Any success for anyone? If you have feedback, please advise…My main questions are:
Is it worth using it as a topical? Will the side effects be less than taking it orally?
What would be the best way to apply it? I may use progesterone topically so I was thinking on mixing with that? or with the rogaine foam I will use alternating with progesterone.

Thank you guys!
