If it's one or the other, I would definitely go for HRT. Both will help a ton with your appearance but HRT has the added affect of making you feel better (for most/many) and their affect on your outward appearance happens a bit faster too. Well idk abt laser, maybe that's faster, I am blonde and stuck with electroysis. Never discount how big of a deal removing facial hair is though, it's major.
Another thing, for what it's worth (nothing) my electrologist told me that once I got on hormones I would see faster and more permanent results, but in reality that did NOT happen from what i could tell.
