TLDR 5% minoxidil foam used once daily is as effective as 2% minoxidil solution used twice daily for hair loss in women, but with fewer side effects like itching and dandruff.

In this study, researchers compared the effectiveness of 5% minoxidil foam used once daily versus 2% minoxidil solution used twice daily in the treatment of androgenetic alopecia in women. They found that the 5% minoxidil foam showed similar effectiveness to the 2% minoxidil solution, but with lower rates of side effects such as itching and dandruff. This is significant because it provides evidence that female patients can use the low-irritation foam-type minoxidil.
