I see that the concentration for male dosage is twice that for females. Both are to be used twice a day. Could a female use the male strength but only once a day. It would produce the same dose over a 24 hour period.
Studies have shown that minoxidil 5% foam just needs to be used once daily for women. I have included a 2011 reference below for interest:
Blume-Peytavi et al. A randomized, single-blind trial of 5% minoxidil foam once daily versus 2% minoxidil solution twice daily in the treatment of androgenetic alopecia in women. J Am Acad Dermatol. 2011 Dec;65(6):1126-1134.
