Gotcha! I think tressless could still be a good resource then, but from what I recall it’s mostly men.

My mom and sister have both started using minox and have started to see some positive results, but I’m not sure of the biological process that would cause follicle dormancy/death in females, so I’m not sure what results you could expect. Also to note, minoxidil can cause some shedding at first, so your hair will look thinner for a few months until it starts to regrow more.

I am not a doctor, but have had some results using minoxidil and Foligain’s Minox&Triox spray. As was pointed out in the other comment, hair follicles will start to die as you age (assuming you’re male) this is caused by DHT which is a result of testosterone breaking down. First the follicle goes dormant, and then dies. Depending on how advanced your thinning is, you can likely reactivate and save between few and most of the follicles. I hate recommending Reddit, but r/tressless is a good resource, but they pass around a lot of lingo so be prepared for that.
