I started using minoxidil 4 days ago and today i started noticing black eye rings (not much but noticable more then before) under my eye. I apply minoxidil in the morning and just before going to sleep. I think it is possible that same of minoxidil get on my pillow and then absorb in the skin under eyes. I wonder if I buy a foam (i am using topical solution) and wash my hair maybe before going to sleep will help me prevent from this side effect? Or what could I do, I really dont want to stop using minoxidil? Maybe apply once a day? I am using spironolactone and nizoral too.
