Can I use minoxidil every alternate day along with finasteride every day. I suffer from seborrheic dermatitis?

I think your doctor is doing a good job managing your problem and would strongly suggest you contact his/her office with your question. 

yes  you can  alternate the use of minoxidil every other day and anti dandruff lotion every other day.your doctor recipee and treatment way is true. dont forget that salicylic acid and anti dandruff lotion works for seborreic derm.

Minoxidil will make your seborrheic dermatitis worse as it drys your skin and makes your scalp flake more
