Hello Dr Rassman
Do you think if I use Ketoconazole 2% lotion ( 60% isopropyl alcohol , 38% water ) it can have bad effect on my skin (not hair loss)?!?!! I mean is isopropyl alcohol bad for your skin? I want to use .5ml per day or every other day on my vertex area! Thank you
Ketoconazole 2% is an antifungal medication that is prescription for those in the United State, although some countries allow it to be sold over-the-counter. Are you treating a fungus on your scalp? Otherwise, why would you want to use a antifungal medication on your scalp? I hope you do not think it may grow hair, because it will not. I would discuss your desires with your physician, particularly if the medication was prescribed to you.
I do not believe isopropyl alcohol (also known as rubbing alcohol) is necessarily bad for your skin when used in a medication like that, but unnecessary use of a medication would be more harmful and it may dry the skin. Many topical products use alcohol as an additive, like Rogaine. You can read the health hazard information here.
