Minoxidil temporary use?
Im curious about whether minoxidil hair always regresses to the baseline after stopping in the case of transfeminine HRT. Most people would say "YES" But couldn't it be possible in theory for one's DHT levels to not be low enough to permit regrowth BUT also not cause loss? (e.g. someone who had male hormone ranges for a while and no longer does)
Obviously someone with female ranges of hormones shouldn't get much hair loss at temples. But sometimes, temples regrowth for MtF doesn't always happen. When it comes to beard growth, for example, the minoxidil *can* be stopped because the beard follicles just needed a jump start but now can have plenty of DHT to keep themselves alive (i guess it's intracrine/paracrine produced)
So maybe minoxidil can be used temporarily to bring hairs "up to speed" without them all falling out again when stopping, in the case of an MtF scalp? I'm not sure.
On one hand, if it's right that minoxified beard follicles survive post-treatment by making their own DHT, afaik there are no growth factors that scalp hair follicles in an estrogenic/low-androgenic environment could intra/paracrinely induce.
On the other hand, women less often lose temple hair for SOME reason. So if the hair is brought back through minoxidil, why would it disappear again if the hormonal environment is female?
