Thank you my friend Bryan but, can I turn my face blue holding the breath?. I see, it must be a contagious agent around us.
I recommended the same for Mr. Foote now because he is trying to find out gender differences in lymphatic system in order to explain the huge different incidence of alopecia.
But, please Bryan, don't put words in my mouth. Sebum don't produce common baldness, but it is necessarily implicated in the earliest steps of this multifactorial process.
Regarding androgens concentration in hair follicles, please, do you know if they are constant in all phases of hair cycle?...,. Possibly don't, then it is very important the local effects of them, letting the asinchronicity of humans hairs.
Bryan you know very well that current androgenetic theory have a lot of problems, by example one of them: don't explain why in common alopecia the baldness begin in the front and crown (Ref. Hamilton scale) when androgens affect at the same time to ALL hairs. So the hair loss should be uniform pattern. My theory explain easily a lot of things.
On the other hand, can a scientist detect gender differences in scalp hairs?..., Possibly don't, then why don't affect equally at both sexes?.
Finally, if anyone says: "I have a dinosaurian in my garage", he must have strong evidence. My theory is based in the equality of all scalp hairs, so the androgenetic theory must probe very well that I am wrong. Occam razzor.
