thats not very nice. WNT signaling DOES show effectiveness in humans. what the f*** are you talking about. 10% increase in density is better than finasteride do you not understand that? finasteride has 9% increase in hair count after 6 months lol.. androgens are the problem in so far as they cause downstream reactions, nothing more.

you are one level too high.
"Changes in hair follicle and hair size are believed to involve signalling between the hair follicle components via paracrine factors. It is believed that androgens exert their effects on hair follicles via the mesenchyme-derived dermal papilla cells by altering the regulatory paracrine factors produced by the dermal papilla itself and affect the other follicular components.
"
they enter the dermal papilla cells, cause transcription of certain genes which trigger see signaling effect. growth factors are absolutely included in thsi. we don't know much about it but to say androgens are the problem is ridiculous. cell signaling is the answer. they also enter dermal sheath cells which are responsible for repopulating the dermal papilla with DP cells that themselves induce hair growth. so you have two types of cells as a target and the androgens are not the direct issue, they just trigger something in people who are prone to it.
" The mesenchyme-derived dermal papilla in the center of the hair bulb (
Fig. 1F) (
4,–
6,
25) initiates and regulates much follicular growth activity
via paracrine signaling (
26). Androgens are believed to act
via androgen receptors in dermal papilla cells that form hormone-receptor complexes that act as gene switches, which activate cell-specific gene transcription and alter dermal papilla production of short-distance paracrine signals that influence other follicular cells. This closely resembles androgen action
via the mesenchyme/stroma in developing and cancerous prostates (
2,
27)."
