Most of what determines how a wax goes is decided before you arrive. Hair length, where you are in your cycle, what you did to your skin in the previous 48 hours, and what you took beforehand.
None of it is complicated and almost none of it is explained when you book.

Hair length: the one non-negotiable
About a quarter of an inch, roughly two to three weeks of growth from a shave.
Too short and the wax cannot grip. Your therapist has to go over the same area repeatedly, which means more passes, more skin trauma, and a worse result. Too short is the single most common reason an appointment goes badly.
Too long is a smaller problem but it hurts more and can be messier. If your hair is well over half an inch, trim to about a quarter rather than shaving.
Do not shave in the two weeks before. This is the mistake people make when they feel self-conscious about arriving with growth, and it defeats the appointment.
Timing it with your cycle
Pain sensitivity varies through the menstrual cycle, and skin is generally more sensitive in the days immediately before and during a period.
The comfortable window is usually the week after your period ends.
The week before your period is typically the most sensitive.
During a period, most salons will still see you if you are wearing a tampon or cup, but check when booking. It is a normal question and they are asked it constantly.
Forty-eight hours before
Exfoliate gently, once. This lifts dead skin so hair releases more cleanly and reduces trapped regrowth afterwards. Gently is the operative word, and 48 hours before rather than the same day. Exfoliating immediately before means arriving with skin already abraded.
Keep the skin moisturised up to the day before. Supple skin releases hair more easily.
Do not use retinoids or acids on the area for at least three to five days beforehand, longer if your skin is sensitive to them. They thin the outer layer, and wax on skin prepared that way can lift more than hair.
Avoid sunburn. Waxing sunburnt or recently sunburnt skin is asking for lifting and pigmentation.
The day of
Shower beforehand, warm rather than hot, and use water or something gentle rather than soap. Clean skin is easier to work with and lowers the bacterial load on follicles that are about to open.
Do not apply anything to the area. No oils, no moisturiser, no powder. Wax needs to grip hair, and a film of product interferes with that.
Consider a painkiller. An over-the-counter analgesic taken about half an hour beforehand takes the edge off for many people. Avoid aspirin, which affects bleeding.
Skip the caffeine. It increases sensitivity for some people.
No alcohol. It thins blood and does not do what people hope it does.
Wear loose cotton underwear, because you will be putting it back on immediately afterwards onto skin you want to keep friction off. The reasoning is in after a Brazilian wax.
What to skip entirely
- Shaving in the two weeks before. The single most common preparation error.
- Retinoids and acids on the area in the days beforehand.
- Tanning, real or spray, in the 24 to 48 hours before.
- Exfoliating the same day.
- Applying oil or moisturiser the morning of.
- Going in with sunburn or broken skin.
If it is your first time
It will hurt, and less than you expect. The first pass is the worst and it is over in seconds.
Say it is your first time. A good therapist will work in smaller sections and talk you through it.
You will be more exposed than you expect and your therapist has done this thousands of times. Say what you are and are not comfortable with.
Expect more redness than a regular would get. First waxes remove hair that has never been pulled and the response is stronger.
Book the next one before you leave, three to four weeks out. Consistency is what makes waxing progressively easier, because hair grows back finer and less densely when the cycle is maintained.
And know the alternative. If pain is the barrier, shaving properly with the right technique is a legitimate choice, and the full comparison is worth reading before you commit to a routine.
Medications and conditions to mention
Tell your therapist, at booking rather than on the table, if you are:
- using retinoids, topical or oral, including isotretinoin, which is usually a firm no for waxing
- using topical steroids on the area
- taking antibiotics that increase photosensitivity or skin fragility
- pregnant, since sensitivity is higher and some salons have their own policies
- managing eczema, psoriasis or lichen sclerosus on the area
- prone to cold sores or folliculitis
- diabetic, since healing and infection risk differ
None of these are automatically disqualifying, and all of them change how a careful therapist works.
What to bring and wear
Loose cotton. A dress or a loose skirt is ideal because you are not pulling anything tight over the area afterwards.
Bring a spare pair of underwear if you are going somewhere afterwards.
Do not plan a gym session, a swim or a hot bath for the rest of the day.
Frequently asked questions
How long should my hair be for a Brazilian wax?
About a quarter of an inch, roughly two to three weeks of growth after shaving. Shorter than that and the wax cannot grip, which means repeated passes over the same skin and a more traumatic appointment for a worse result.
Should I shave before a Brazilian wax?
No. Shaving in the two weeks before is the most common preparation mistake. The hair needs enough length to be gripped, and arriving freshly shaved usually means the appointment cannot be done properly.
Does it hurt less at a certain time of the month?
For most people yes. Skin sensitivity is generally higher in the days immediately before and during a period, and the more comfortable window is usually the week after it ends.
Can I get waxed on my period?
Most salons will see you if you are wearing a tampon or menstrual cup, though policies vary so it is worth asking at booking. Be aware you are likely to find it more painful than usual.
Should I exfoliate before waxing?
Yes, gently, about 48 hours beforehand rather than the same day. That lifts dead skin so hair releases cleanly. Exfoliating on the day means arriving with already abraded skin, which increases irritation.
Can I take a painkiller before a wax?
An over-the-counter analgesic taken around thirty minutes beforehand helps many people. Avoid aspirin, which affects bleeding, and avoid alcohol, which does the same and does not reduce pain.
