Really good work! I wanted to ask has anyone considered looking at women with traction alopecia for similar histological markers as men with AGA? This would be a good comparison and would add some extra weight towards the scalp tension hypothesis.

Thanks Benjamin! I haven’t seen Brian Dye’s video, but I’ve read his paper on malocclusion and AGA. I think there’s merit to some sort of anatomical component acting as a driver (or accelerator) of AGA, even if it doesn’t explain all AGA cases. The botox studies on intramuscular injections (in my opinion) are the most compelling evidence we have on this. But we need more results replication across larger numbers of participants. I hope Brian Dye makes more of an effort to flush out his hypothesis (for example, using radioactive dye to track blood flow differences in balding versus non-balding scalps in relation to the artery in question).

His hypothesis for the cause of hair loss is IMO flawed and outdated (as his field of education isn’t hair loss disorders), but what’s interesting are his observations about the relation between the jaw and the superficial temporal artery.

I have read some theories regarding this, and if I understand them correctly (I’m simplifying), occlusion of the artery cause inflammation, which irrigates in the scalp. Due to this inflammation, androgen receptors become upregulated, causing DHT to miniaturize the follicles.

You and your team are no doubt more updated on this than me, although I hope this is stirring up some new ideas.

Cheers
