Why Is Minoxidil Foam Not FDA Approved for Women?

Why are certain minoxidil products approved only for men and not women?

Do minoxidil products work on the frontal part of the scalp as well as on the vertex?

I have a 21 yr old daughter who has hair loss. The thinning is most noticeable on the front of her scalp so I want to apply there, as well as on vertex. I would like to try the new Pfizer foam product because the topical solution is difficult to apply and makes her hair look greasy. It seems more goes on her hair than her scalp. But the Pfizer web site for the foam product says the foam is for men only and only for the vertex of the scalp. If minoxidil topical solutions work on the frontal part of scalp, why doesn’t the foam? Is it just that Pfizer’s studies on this product submitted and approved by the FDA only looked at application to the vertex?

You guessed it. The drug company can only claim what they can prove. By not making any statements about frontal use or women’s use, it does not mean that it is not safe nor effective. The risk (minimal) is yours for making the decision.
