Male facial hair is structurally different from normal female facial hair. Most female facial hair is vellus hair, very very fine, short, very thin.
Male facial hair is thick and heavy and requires a deeper anchor than female hair. Testosterone helps in this regard by making male facial skin thicker to support these heavier hairs. Thus getting on HRT and the facial skin may begin to thin as T-production falls and estrogen levels soar.
This, in turn, may make hairs easier to identify and extract for electrology purposes. But... the downside is that the face no longer properly supports these thick heavy hairs either. In my own case, the areas still having significant male facial hair, like the lower chin and jawline, actually become irritated and sore the last 10 days or so leading up to my next facial hair removal session. Those areas of my face also become very unsightly as I approach the next session because the male facial hairs cause the surrounding skin to thicken, creating "bumps" where each hair is, almost looking like folliculitis but not the same. Within 24 hours of the hairs being removed at my next session, the entire face settles again, into a very comfortable mode for the next two weeks, then two to three weeks as hair begins to show again gradually thickening then one to two weeks of heaviest growth and the most irritation.
As I've removed hair, more of the face stays quiet and without problems, but the areas where hair was thickest is also where regrowth has been thickest, so have taken the longest to begin to really thin out.
