bottom of My minoxidil bottle is 1-2 very small beard hair and some smal black dirt or something dont know really but its tiny Will it f*** upp My minoxidil?
Will not f*** it up.
Are your sure there is no powder at the bottom?
That powder could be minoxidil itself that has precipitated if the solution was not made very well.
If you are sure it is just dirt, it's OK.
