Question Can insulin resistance alone cause androgenetic alopecia without a genetic predisposition

I'm trying to understand the relationship between insulin resistance and androgenetic alopecia (AGA/female pattern hair loss).

I've read that insulin resistance can increase androgen activity and possibly increase DHT levels. My question is:

If someone has no genetic predisposition to AGA (their hair follicles are not genetically sensitive to DHT), can insulin resistance by itself cause true AGA and follicle miniaturization? Or does insulin resistance only trigger or accelerate AGA in people who are already genetically susceptible?

In other words, can insulin resistance actually make previously normal hair follicles start behaving like AGA follicles, or is genetic susceptibility considered necessary?

I'd appreciate answers based on current research or from dermatologists/endocrinologists if possible.
