Completely agree.

I think the value of male semen for the health and growth of female hair is totally undermined and underutilised.

Any idea how long semen should be kept in a female's hair for the maximum benefit? Overnight?

And coming back to what you said in your message - is it the sperm itself in male semen that carries the benefit? Does this mean female cum and juices would not have the same impact? I was thinking of some known squirters out there (Adriana Chechik immediately comes to mind) who could easily drench a female partner to the roots when she orgasms.
