Hey guys...I'm considering using a concealer for minor hair loss....I like the idea of courve, or the toppik hair thickening spray...basically painting the scalp...I usually only use my Nizoral 2-3x a week, but I was wondering if I will have to wash this stuff out daily, in order for my minoxidil treatment to be effective...like if the concealer (scalp paint lol) is on, would this make minoxidil application entirely useless? If so, this could be ridiculously expensive :/
