Tretinoin use with minoxodil anyone use with success?

I recently read an article regarding the use of tretinoin to increase the effectiveness of minoxidil. I’m wondering if anyone is using this and if you are seeing results?

I recently went for my derm check up and was prescribed Tretinoin for some problem ingrown hairs on my face that get hardened skin on top rather than coming out. I only need a little bit for this issue and I’m left with a lot in tube when I get another.

I’m wondering if I should try using it on my scalp because I am feeling the oral minoxidil and finasteride isn’t as effective as I’d hoped.

I also heard of ketoconazole topical for scalp use. Any thoughts?
