A. The natural form of minoxidil crystals that are used in formulating 2% – 5% minoxidil solutions are white, coarse and hard, similar to table salt. Costly precision equipment at Regrowth’s compounding lab is used to pulverize these crystals so they are less than 25 micron in size (similar to talcum powder). Micronization results in improved dissolution, and in a smooth lotion, which, because it is heat activated, is better, absorbed as evidenced by an almost total lack of residue where it is applied.
