Not very knowledgeable on all this, but, the best method is to one day get laser.

That's probably not within your reach if you're asking so, let me say, from my experience with really visible, high contrast and dense body hair, any method of uprooting (plucking or waxing), both gives a pretty good result of hairlessness if you get all of them, and, after 2-3 cycles of growing and uprooting again, that hair is permanently 10-15% less visible (primarily thinner, also straighter). If you know where to look, my arm hair has a transition line between the side I plucked, and the side I haven't yet. It's unassuming, but still there, after plucking them 3 times, more than 4 months ago.

The disadvantage of that is that you need to let them grow a bit, in order to have something to grab on to.

Laser is #1, electrolysis as well but it takes longer and is more painful. From what I hear a lot of trans girls, including myself, try to get laser first then electrolysis to clean up a bit.

Until then get a good foundation and concealer and put it on after shaving. This should cover up 90% of the shadow.

I shave with specific brands of disposable twin-blade safety razor (Dorco, BIC, whatever gets you closest without cutting the skin) and shave gel. Gel seems to work a lot better than Barbasol cream.

You can also use hair removal cream for touch-ups, though my facial hair is unfortunately a lot tougher than hair removal cream alone can handle.

I hear that epilators (basically like an electric razor that goes a little deeper) work well, at least for body hair, though I haven't tried one yet.

I hear that an epigenetic medication (not HRT) reduces the thickness of non-scalp hair to the genetic level you would have without androgens, but other factors like a history of shaving and your specific ethnicity may reduce the de-hairing effect. Many cis women shave.

You need a color correction cream to put on prior to your foundation. Orange is the best if you are pale skinned with dark facial hair. Don't be afraid to go with a true orange color - that's how you get it to cancel out the (typically) blue shadow you are seeing.
