As i mentioned, when waxing the regrowth is almost non-existent after all these years.
I used to use something called Magic Shave (get the "platinum" one) that is basically a powder that you mix with water and then apply to the desired area. after a few minutes you rub gently with a washcloth and all the hair is gone. Honestly I did that until i got up the nerve to wax.
I'm sure i've been shaving/waxing/magic-ing longer than most, if not all, of you. If you want it slick that's a good choice.
If you just want to trim that's fine too and the Phillips OneBlade does a great job for that.
