So does anyone out there wax ALL the hair down there? Is this what a Brazilian wax is? If not, how does it differ from a regular bikini wax.
Can you have ALL the hair down there waxed? Even those ones in the REALLY sensitive region? If so, how?
In answer to your questions, a Brazilian wax does involve removing all the hair down there. Meaning removing your “V” of hair in the front, plus everything around your your vaginal lips, even your butt-hole. A bikini wax, on the other hand, just kind of shapes up your triangle so you don’t have stragglers poking out the sides. You can “shape it up” more or less as much as you want - just removing the stuff on the sides that pokes out from under your underpants and any hair on your upper abdomen and thighs if you have any, or you can remove most of it so you have just a tiny strip in the middle.
I used to get bikini waxes on a regular basis. I like the look better - although I am not particularly hairy, I’d occasionally have a straggler, and bikini waxes versus shaving just makes the area less itchy and more tidy than shaving there. I have never, nor do I ever expect to get a Brazilian. I understand they’re really painful. I was curious and asked my waxer about them, and she said that most women who do it take several painkillers before and after. You can inflame some pretty sensitive skin. I’m not sure entirely how they do it, though I suspect they do it exactly the same as a bikini wax - by spreading warm wax on the area with the hair, applying a strip and ripping it off. Some places don’t do anything beyond bikini waxes and waxes on other regions that aren’t as sensitive because if your skin is really sensitive, Brazilians can be very, very painful and may take off some skin.
Brazilian waxing is the full, complete, and total treatment. Think Telly Savalas down under.
