This flies in the face of absolutely everything we safely know about the effects of hormones on hair growth.

Sperm should naturally be full of male hormones that usually prevent hair growth or even cause hair loss on the scalp (as with me).

Why would a woman with a declining estrogene level use the very substance (which ever way you apply it) that is sure to make things worse if what she really wants is to keep long and healthy hair? This actually only makes sense if she wants to grow a beard instead.
