Can You Get a Brazilian Wax While Pregnant? What Happens If You Go Ahead

Yes. In a pregnancy with no complications, a Brazilian wax is a cosmetic decision rather than a medical one. Wax acts on the outer layer of skin and on the hair follicle, and no published study links pubic waxing to contractions, preterm birth, or any effect on the baby; no professional obstetric body has issued guidance on it either way. Three things do change. Skin carries more blood and marks more easily, lying flat stops being neutral after about 20 weeks, and a skin infection that you would have ignored before your pregnancy now gets handled by someone who is also watching a fetus. The US Food and Drug Administration regulates wax as a cosmetic, leaves professional hair removal to state and local authorities, and says of waxing only that it may cause skin irritation and infection.

I answered a helpline for nine years for people whose drug coverage had just ended. I am not qualified to tell you whether any of this is safe for your pregnancy, and I said a version of that sentence most days. What I know is the shape of the call that comes after someone has already gone ahead, and the order those calls should be made in. That is most of what follows.

The appointment, in numbers

European Wax Center, one of the larger US chains, puts a Brazilian at roughly 15 minutes on average, longer on a first visit because of the consultation, and quicker for clients who keep to a schedule of every three to four weeks. Wax manufacturers including ItalWax set the minimum hair length at about a quarter of an inch, near 6 mm, which is two to three weeks of regrowth from shaved skin. Most studios will not rebook a Brazilian inside four weeks of the last one, because shorter regrowth snaps at the surface instead of lifting from the follicle.

Hold onto the 15 minutes. It is the only figure in the appointment that interacts with your pregnancy, because it is 15 minutes flat on your back with your knees apart.

The patch test is the second number worth knowing. ItalWax's own instruction is to put a small amount of the same wax on the inner forearm or behind the ear at least 24 hours before the service, then watch that spot for redness, itching or swelling across the following 24 hours. Habia, the UK hair and beauty industry authority, recommends patch testing for waxing in its code of practice. I could find no jurisdiction that makes it law. Where the manufacturer instructs a test, salon insurers generally hold the therapist to the instruction, which is why a studio that skips it is telling you something about its paperwork. If you have never been waxed, pregnancy is a poor moment to find out how you react to pine resin.

The position is the part to plan around

ACOG Committee Opinion No. 804, published April 2020, advises against a persistent supine position during exercise beyond 20 weeks of gestation, because the weight of the uterus compresses the aorta and vena cava and reduces the blood returning to the heart. StatPearls, the clinical reference used across US residency training, puts the same threshold on aortocaval compression syndrome: it occurs in patients with gestational age greater than 20 weeks, and it resolves when the woman is turned onto her side.

Nobody publishes a maximum number of minutes; the threshold is written in weeks. ACOG's sentence is about exercise, and a wax is not exercise, so a 15-minute service sits in a gap the guidance does not address. In practice, the number of minutes you tolerate on your back is something you discover on the table, usually as light-headedness or nausea partway through.

Two things help. Ask before you undress whether the therapist can wedge your right hip or tilt you toward your left, which most treatment couches allow. And say something at the first wave rather than the third; the person most likely to stay quiet out of politeness is you.

Booking at 37 weeks

At 37 weeks you are early term. ACOG Committee Opinion No. 579, which adopted the Defining "Term" Pregnancy Workgroup's categories in 2013, sets early term at 37 0/7 through 38 6/7 weeks, full term at 39 0/7 through 40 6/7, and late term from 41 0/7. Thirty-seven weeks feels like the end and is categorised as the start of it. Nothing about waxing changes at that boundary.

What changes is reach and policy. You cannot see the area or check the result, and the therapist works around a bump that limits how far your knees open, so sessions run longer and push against the positioning problem above.

Salon policy gets misread constantly. Many chains ask for written sign-off from a doctor or midwife past a certain week. That form is a liability document for the salon's insurer. A clinician who signs it is confirming they know of no reason you should not have a cosmetic service, not certifying that it is medically beneficial. A salon that books you without asking anything has not cleared you either.

Hair removal before delivery: what the evidence actually says

Removing pubic hair before a vaginal birth has been studied, and the trials found no benefit. The World Health Organization's 2018 intrapartum care recommendations state that routine perineal or pubic shaving prior to giving vaginal birth is not recommended, a conditional recommendation resting on very low quality evidence drawn from a Cochrane review of three randomised trials in 1,039 women. WHO adds two qualifiers people rarely hear: the decision should be left to the woman rather than her caregiver, and the recommendation does not apply to women being prepared for caesarean section.

For caesarean, the clinical picture is specific and it is not yours to manage. NICE guideline NG125 says not to use hair removal routinely, and that where hair must come off, it should be done with electric clippers with a single-use head on the day of surgery, never a razor. The CDC's 2017 surgical site infection guideline reaches the same place. In caesarean data, razor removal carries roughly twice the surgical site infection risk of clipping.

The comparison that matters: a Brazilian wax at 38 weeks is a comfort and preference decision with no demonstrated obstetric benefit, while clinical hair removal before a caesarean is a timed, clipper-based step performed by the surgical team on the day of the operation. Being waxed does not spare you the second and does not interfere with it. If you are hoping a wax means the hospital will not touch you, that is not what it buys.

Does it hurt more?

Possibly. The research pulls both ways, which is more interesting than the confident answer most salons give.

Researchers testing 76 first-time mothers in 2012 found heat pain thresholds climbed by about a degree Celsius between 32 to 33 weeks and 39 to 40 weeks, and climbed again in early labour. A 2016 study of 33 women found no significant change in conditioned pain modulation, p = 0.83. A 2024 PLOS One study found thresholds fell across pregnancy while tolerance held flat.

So any pregnancy analgesia in humans looks modality-specific and modest, and nobody has tested waxing. The stronger argument for more discomfort is anatomical. The vulva carries far more blood in late pregnancy, which is why vulvar varicose veins appear, and waxing over prominent varicosities is worth refusing outright; the pull can bruise vessels that are already distended.

Telling an ordinary reaction from one that needs a phone call

This is the table I wish someone had read to me on the phone.

| | Ordinary reaction to the wax | Infection in the waxed skin | Something obstetric | |---|---|---|---| | What you see | Flat redness, mild swelling, warmth, confined to where wax was applied | Clustered tender bumps or pustules, redness spreading past the waxed area | Fever, tightening, bleeding, leaking fluid, reduced fetal movement | | When it starts | During the wax and the hours after | Usually a few days later | Any time, and often unrelated to the wax | | How long it lasts | Settles within 24 to 48 hours | Runs past 48 hours and worsens; mild folliculitis takes 3 to 7 days | Does not settle on its own | | Who you call | The salon | GP or urgent care, plus the salon for the product record | Maternity or obstetric triage | | How soon | Next appointment | Within a day or two | Straight away |

Redness still there on day three, or spreading outside the waxed rectangle, has stopped being a waxing question. NSW Health's fact sheet names what contaminated wax transmits: staphylococcal and streptococcal infections, and folliculitis.

Fever is where the columns separate hardest, and it has a definition. ACOG Committee Opinion No. 712 documents intrapartum fever as a single oral temperature of 39.0°C (102.2°F) or higher, or one of 38.0 to 38.9°C (100.4 to 102.0°F) still there when you retake it 30 minutes later. That 30-minute repeat is the specific thing a triage clinician is trying to establish. You can hand it over already done.

Who to call first

Nine years of listening to people describe symptoms to the wrong department taught me that the order is most of the outcome.

1. Take your temperature, write down the reading and the clock time, and take it again 30 minutes later. Write that one down too.
2. If there is fever, tightening, bleeding, leaking fluid or reduced movement, call maternity or obstetric triage first. Not the salon, and not a friend who has had four children.
3. Open the call with gestational age in weeks and days, then both temperature readings with their times, then the date and time of the wax. In that order, because it is the order they are filling in a form in.
4. Before you hang up, get the name of who you spoke to and ask what the call-back window is, so you know when silence stops being normal.
5. Call the salon only for skin confined to the waxed area, and when you do, ask for the wax brand and your patch test record rather than reassurance.

Out of hours, skin-only problems go to urgent care or, in the UK, to NHS 111. Anything in that third column goes to the maternity line at any hour, and no maternity unit anywhere considers a 3 a.m. call about reduced movement a nuisance.

What to ask before you book

Hygiene rules for waxing are written by state, provincial and national regulators, so what your salon must legally do depends on where you are standing. Every version I read shares one principle. Nothing that has touched skin goes back into the pot.

NSW Health requires that wax and any instrument used to apply it be disposed of immediately after the procedure, with no double dipping, that enough single-use spatulas be available to prevent it, and that wax not be applied to broken skin or over an area where blood has been drawn. Texas puts it in one line at 16 TAC §83.105: no applicators may be left standing in the wax at any time, and wax may not be reused under any circumstances. Washington's WAC 308-20-110 is the instructive exception, permitting double dipping only from a quantity decanted into a single-client, single-use container.

So the useful question is not "do you double dip", which invites a yes-or-no from someone trained to say no. Ask what happens to the wax between clients, and whether they decant. Ask whether gloves stay on throughout. Then ask what brand of wax they use, and write it down, because that is the piece of information you will need if your skin reacts and you end up describing it to someone else.

Frequently asked questions

Can a Brazilian wax be done at 37 weeks of pregnancy?

Yes, if your pregnancy is uncomplicated and your clinician has no objection. At 37 weeks you are early term by ACOG's definition, not overdue. The practical limits are positioning, since lying flat is less comfortable after 20 weeks, and salon policy, which often requires written medical sign-off late in pregnancy.

Is a Brazilian wax before delivery considered safe?

It carries no known obstetric benefit and no documented obstetric harm. The World Health Organization's 2018 intrapartum guidance does not recommend routine perineal or pubic shaving before vaginal birth, and leaves the choice to the woman. Hospitals do not require you to be bare, and caesarean teams clip on the day.

How can pubic hair be removed during pregnancy?

Trimming with scissors or clippers is the lowest-risk option and needs no skin contact. Shaving works if the razor is clean and sharp; the FDA advises shaving wet and in the direction the hairs lie. Waxing and sugaring are options in a low-risk pregnancy. Laser is usually deferred until after birth.

Does Brazilian waxing hurt more during pregnancy?

Possibly, though the research points both ways. A 2012 study of 76 first-time mothers found heat pain thresholds rose about a degree between 32 and 40 weeks, while a 2016 study found no change in pain modulation and a 2024 study found thresholds fell. Nobody has tested waxing specifically.

What should I ask a waxing salon about hygiene?

Ask whether applicators are ever re-dipped, whether wax is decanted into a single-client container, and whether gloves stay on throughout. NSW Health's waxing fact sheet requires single-use spatulas and immediate disposal of used wax. Ask what brand of wax they use, so you can name it later if your skin reacts.

When should I ask my prenatal clinician before booking?

Ask before booking if your pregnancy is high risk, if you take blood thinners or have a clotting disorder, if you have gestational diabetes, vulvar varicose veins, or any rash, cut or skin condition in the area. Ask too whether your salon demands written sign-off past a certain week, since many do.
