Can you use minoxidil on wet hair or will it effect its potency?

Minoxidil  can be used on slightly wet hair. The concept is that you don't want to dilute the minoxidil and have it on the hair shaft itself rather than the scalp. An alternative is to use compounded oral minoxidil.Jeff Rapaport MD FAADRealself All-star

It may affect absorption when your hair or your scalp is wet. It is recommended that the hair be dried and treated with this drug to avoid affecting the effect.

Hello and thank you for your question. Ideally your hair and scalp should be dry. However you can apply Minoxidil if your hair is slightly damp and you scalp is pretty dry. I hope this helps. Good luck to you.

Yes, I generally tell my patients to use minoxidil after a hot shower.  The hair can be moist when you use it. The liquid is better than the foam because it gets more on the scalp.
