Women can use Strands also. For scalp application .. Instead of the usual 7 sprays per application, just use 2 sprays per application. Effectively, that will result in a 2% minoxidil application.
For men, the recommended minoxidil dosage is 6% (7 sprays).
And for women, the recommended minoxidil dosage is 2% (2 sprays). If 2% is not effective, then women can try higher dosage of minoxidil (3 to 7 sprays of Strands).
