How early should I start treatment?

As early as possible, but it’s never too late to try treatments for androgenetic alopecia. Reversing hair loss caused by androgenetic alopecia (AGA) becomes more challenging the longer it goes untreated. This is related to progressive miniaturization of the hair follicles, which is driven by genetics and a hormone called dihydrotestosterone (DHT). As the follicles get smaller, without intervention, the chance of growing a thick hair from that follicle decreases. Certain drugs have been known to slow down or even halt this miniaturization process. If the follicles are not fully miniaturized, there is a possibility that regrowth with new hairs can occur. This is why the earlier the treatment, the better chances of stabilizing further loss and possibly promoting new growth.
