Ingrown hairs on the backside are one of those things nobody talks about — but nearly everyone deals with. The skin here is thicker, often folded, and almost never exfoliated, which makes it prime territory for hairs to curl back under the surface after shaving. The good news: this is a solvable problem, not a permanent condition.
Here's a straightforward, dermatology-informed routine that addresses both active ingrowns and future prevention.
Why Ingrown Hairs Happen Here
The gluteal area combines several factors that make ingrowns more likely than elsewhere on the body. Friction from clothing and sitting compresses the skin constantly, pushing freshly cut hairs sideways. The skin tends to be drier than other zones because sebaceous glands are less dense. And because most people don't exfoliate this area, dead skin cells build up and block the follicle opening.
According to guidance from the American Academy of Dermatology (AAD), ingrown hairs occur when a hair curves back or grows sideways into the skin — and the risk increases with coarser, curlier hair and insufficient skin prep before shaving. The AAD also notes that removing dead skin cells through regular exfoliation is one of the most effective prevention strategies.
Step 1: Don't Shave Over Active, Inflamed Ingrowns
If you have bumps that are red, raised, or tender right now, shaving directly over them will cause irritation and can introduce bacteria into already-compromised follicles. Give active ingrowns a few days to resolve first.
To help them along:
- Apply a warm compress for 5–10 minutes twice a day to soften the skin and encourage the hair to surface
- Use a product containing salicylic acid or glycolic acid (a 2% salicylic acid toner works well) to dissolve dead skin around the trapped hair
- Do not pick, squeeze, or dig — this pushes bacteria deeper and increases the risk of scarring or infection
Once the bump has flattened and the hair is near the surface, you can gently remove it with sterilized tweezers. If a bump is deeply infected, painful, or growing larger, see a healthcare provider — it may need professional treatment.
Step 2: Prep the Skin Before Every Shave
This is where most ingrown-prone shaving routines fall apart. Rushing the prep step means shaving dry, taut, or unexfoliated skin — all of which increase the chance of the hair catching and curling back.
Shower first. Warm water hydrates the hair and softens the follicle opening. Shave at the end of your shower, not the beginning, so the skin has had time to warm up fully.
Exfoliate the area 2–3 times per week (not on shave day itself, which would irritate freshly shaved skin). A gentle body scrub or an exfoliating mitt removes the dead cell layer blocking follicles. Physical exfoliation here is fine; just avoid over-scrubbing. Chemical exfoliation with lactic acid or urea is also effective and tends to be gentler on skin that flares easily.
Apply a proper shave lubricant — a shaving cream, gel, or balm, not just soap. You want enough slip that the razor glides rather than drags. This matters enormously on uneven skin surfaces like the gluteal fold.
Step 3: Choose the Right Razor
Multi-blade cartridge razors are a significant contributor to ingrown hairs in this zone. Each additional blade lifts the hair slightly before cutting it, leaving the tip fractionally below the skin surface — exactly where an ingrown starts. The AAD specifically recommends single-blade razors or electric razors for people who are prone to ingrown hairs.
A quality safety razor changes the dynamic. A single sharp blade cuts at skin level without the subsurface tug, reducing the mechanical cause of ingrowns significantly. A dull blade of any type is worse than a sharp one — you apply more pressure, get more drag, and create more micro-trauma. Replace or change your blade regularly.
Step 4: Shave Technique for the Gluteal Area
The contours here are awkward to navigate. Go slowly, and keep these principles in mind:
Shave with the grain first. Identify which direction your hair grows (usually downward on the buttocks, but it varies) and shave in that direction. Against-the-grain passes cut closer but dramatically increase ingrown risk in a prone area. If you want a closer result, do a second pass across the grain — never start against it.
Use light, short strokes. Don't press down. The weight of the razor should do most of the work, especially with a safety razor. Rinse the blade frequently to clear trapped hair and product.
Navigate folds carefully. Gently stretch the skin taut with your free hand to create a flat surface before each stroke. This prevents the blade from catching in creases.
Rinse with cool water when done. Cool water helps close the follicle opening slightly, which reduces the window for bacteria to enter.
Step 5: Post-Shave Care That Actually Prevents Ingrowns
What you do in the 24–48 hours after shaving matters as much as the shave itself.
- Apply a fragrance-free, alcohol-free moisturizer immediately after patting skin dry. Hydrated skin is more supple and less likely to trap hairs
- Use a chemical exfoliant (glycolic acid or salicylic acid lotion) on non-shave days to keep the follicle opening clear — this is the single most effective prevention habit
- Wear breathable underwear and clothing for a day or two after shaving to reduce friction while the follicles are still open
- Avoid tight synthetic fabrics that trap heat and bacteria

When to See a Doctor
Most ingrown hairs resolve with good routine. But seek medical advice if:
- A bump becomes significantly swollen, fills with pus, or is extremely painful (signs of folliculitis or abscess)
- You develop recurring ingrowns that don't improve with consistent prevention
- The area has persistent dark spots or scarring after ingrowns clear
Post-inflammatory hyperpigmentation (dark marks left after ingrowns heal) is common and usually fades on its own, but dermatologist-prescribed topicals can speed the process.
The Short Version
Clear any active ingrowns before shaving. Prep with heat and exfoliation. Use a sharp, single-blade safety razor. Shave with the grain. Follow up with moisture and a chemical exfoliant on off-days. Repeat consistently, and most people see a significant reduction in ingrowns within 4–6 weeks.
Frequently Asked Questions
Can I shave my butt if I already have ingrown hairs?
Avoid shaving directly over active, inflamed ingrown bumps — this can worsen irritation and introduce bacteria. Treat the ingrowns first with warm compresses and a salicylic acid exfoliant until they flatten, then resume shaving with improved technique and prep.
What type of razor is best for preventing ingrown hairs on the butt?
A single-blade safety razor is widely recommended for ingrown-prone skin, including by the American Academy of Dermatology. Multi-blade cartridges cut hair slightly below the skin surface, which increases the chance of the hair curling back inward. A sharp, single blade at skin level reduces that risk.
How often should I exfoliate my butt to prevent ingrown hairs?
Aim for 2–3 times per week, but not on the same day you shave. Physical exfoliation with a scrub or mitt, or chemical exfoliation with glycolic or salicylic acid, removes the dead skin buildup that traps hairs inside the follicle.
Should I shave with or against the grain on my butt?
Shave with the grain (in the direction hair grows) to minimize ingrown risk. Against-the-grain passes cut closer but dramatically increase the likelihood of hairs curling back under the skin, especially in an area already prone to friction and follicle blockage.
How long does it take for ingrown hairs on the butt to clear up?
Most individual ingrown hairs resolve within 1–2 weeks with consistent warm compresses and gentle chemical exfoliation. With an improved shaving routine, recurring ingrowns typically reduce noticeably within 4–6 weeks. Persistent or painful bumps should be assessed by a healthcare provider.
