I have a very popular beauty salon. I started waxing "down there" for clients a few years ago, really because DD had a bad waxing experience and I figured I could to a better job myself! My regulars are very attached to me - they say nice things like "I couldn't imagine anyone else doing my bikini now" and I have rave online reviews.
What I'd like you to know -
A bikini (inner thigh and high leg knicker line area) wax is the same as an armpit from a therapist perspective - wear stretchy comfy pants which can be yanked sideways a bit (or your bikini) and you're sorted.
Expect to lie on your side, faced away from your therapist with one knee bent for "round the back" nether regions. Pull your knickers in a bit so your therapist can see without foraging.
Dry skin doesn't like being waxed, and the area is prone to dryness, so moisturise diligently after every shower for a few days and on the day of your wax. It saves the wax sticking you as grippily as a plaster.
Regular waxing makes the hair disappear - like over plucked eyebrows
An experienced therapist makes the experience much less uncomfortable and embarrassing than you might imagine AND successive waxes are increasingly less painful as the skin and nerve endings adjust and the hair regrows finer and less sparse.
A good waxing therapist is hard to find, Google is your friend.
Hardly anyone goes for a Brazilian or Hollywood over the age of 45. It's a generation thing. However if you've built up a regular waxing relationship with the same therapist I'd recommend asking for a "almost Brazilian" clearing most of the labia hair. Most women much prefer it after they've tried it which is worth a thought.
