If before HRT, most your hairs on your face are terminal, electrolysis is worthwhile as it will permanently kill those terminal hairs despite high T levels. T cannot do anything to stem cells deep inside hair follicles because they are destroyed. In regards to hairs that have not become terminal yet, HRT may revert the process but there is no guarantee while electrolysis is guaranteed. Glad it worked out for you but it may not be the same for everyone. I personally think starting electrolysis ASAP is best and it hurts less before HRT, a plus!
