As rogaine is intended for hair regrowth and not to combat hair loss, can it be effective on regrowing hair lost from anything other than male pattern baldness, i.e. traction alopecia, or even a mature hairline?
I wouldn’t expect Rogaine (minoxidil) to regrow either frontal hairlines or hair loss caused by traction alopecia. It’s possible that it could cause hair growth in areas where there wasn’t significant hair previously, though.
