How do you use this stuff???

Anyone got any knowledge on the use of topical spironolactone. I put up a post before but no one had any info. For those who have used, how do you apply the topical spiro? How long do you leave it in? Do you wash it out? I dont know WTF to do with this shit. There is no directions or anything. I dont want to burn the shit outta my scalp if ya huurrr me. Any advice would be sweet. Thanx

you need to call the local pharmacy and see if they know how it is used you might have to call a few different ones
