The answer is yes and no Probably not what you want to hear. If you plan well enough then it can be managed, assuming you’re still light and not tanned.
Here’s the deal, waxing of course is a no no, so while doing laser you can forget that. You need to wait at least 6 weeks since you last waxed before laser as well. You’ll have to shave the area then go for treatment. Now this is where you have to plan, because for at least 2 weeks I’d say, the hair will look like you shaved it and that it’s growing back, but around day 7-10 up until even day 20 it will be falling out. After 3 weeks though, you’ll be totally smooth, and you should remain smooth like that for around 6-7 weeks then it starts to grow back. It will grow back finer and thinner so it will look more natural. The dark coarse hair will go first so shaving it when it comes back probably won’t look too too bad. That’s why I say you have to time it though because it’s those first 3 weeks when it will look iffy. After that it should look completely smooth for weeks. When it does start to grow back though, you can’t wax it, you’ll have to keep shaving it until your next treatment so that’s where it can be a bit tricky.
Summer is hard to start laser especially if you want it to look completely normal. Like for me on my forearms, I shave then do treatments and I find it doesn’t look that bad growing back then it falls out and I’m completely smooth for at least 2 months. It grows back very slowly and only a few hairs at a time, so it looks pretty natural, like as if I just don’t have a lot of hair. But if you don’t want it to look like you have ANY hair, then that will be an issue since you’ll definitely see it when it grows back. For me, yeah I like them to be smooth but it doesn’t look unnatural when it grows back, so your back may be different…
