TL;DR
- Chemical exfoliation with 2% BHA 2-3x a week is the single highest-impact habit
- Shave in the direction the hair grows so the regrowing tip points out of the skin
- Swap the blade every 5-7 shaves, the cadence the AAD recommends
- Moisturize daily with a ceramide lotion to keep follicle openings pliable
- For a bump you already have: warm compress, gentle acid, and no plucking
Here's how to prevent ingrown hairs with seven habits, ranked by how much each one helps. The first three do most of the work, so start there.
How To Prevent Ingrown Hairs: The Seven Habits, Ranked
The American Academy of Dermatology advice on razor bumps comes down to four ideas: clear the dead skin, shave the way the hair grows, use a sharp blade, and keep the hair soft. Every habit below serves one of them.
A light routine you run every week does more than one hard scrub on a Saturday. The table below maps it out by time of day.
Your Morning + Night Prevention Routine
| Time | Action | Product |
|---|---|---|
| AM (shower) | BHA body wash 2x/week, gentle cleanser other days | CeraVe SA Body Wash |
| AM (post-shower) | Body lotion on shaved zones | CeraVe Daily Moisturizing Lotion |
| Pre-shave | Warm water for 3 min, beard oil or body oil | Aveeno body oil |
| Shave | With the grain, sharp blade, short strokes | Fresh Gillette Venus cartridge |
| Post-shave | Alcohol-free, fragrance-free lotion | Gigi Slow Lotion |
| PM (instead of a BHA wash day) | Leave-on salicylic or glycolic toner | Paula's Choice 2% BHA Liquid |
| Weekly | Physical mitt + BHA wash stacked | Korean exfoliating mitt |

Habit 1: Chemical Exfoliation With A BHA (The Non-Negotiable)
Salicylic acid is oil-soluble, so it gets into the follicle and loosens the plug of dead skin trapping the hair. The AAD notes that removing dead skin cells reduces the number of hairs that curve back into the skin.
Paula's Choice 2% BHA Liquid is the famous leave-on pick for the face. For the body, where most ingrowns show up, the cheaper CeraVe SA Body Wash uses the same active and rinses off in the shower.
Daily acids on thin skin like the groin and underarms can irritate it enough to cause ingrowns. Two or three acid days a week, counting any post-shave toner, is the sweet spot.
Habit 2: Shave With The Grain, Every Single Time
Dermatologists agree on this one. Shaving against the grain can cut the hair below the skin line, so the regrowing tip points sideways into the follicle wall instead of straight up.

Direction varies by body zone. The butt shaving guide, the smoother thighs guide, and our inner-thigh ingrown hair guide map it out per area.
Habit 3: Replace Razor Blades Before They Tug
A dull blade pulls the hair before it cuts, which can snap it below skin level. The result looks the same as an against-the-grain shave: an angled tip that curls back in.
The AAD says to swap the blade or toss a disposable after 5 to 7 shaves. If you shave your whole body, you'll hit that number faster than you'd think.

Habit 4: Pre-Shave Softening (Warm Water Or Oil)
Warmth and moisture make hairs swell, and the AAD says that makes them less likely to curve back into the skin. Shave at the end of your shower, or hold a warm washcloth on the area for five minutes.
A pre-shave oil like pure jojoba oil, argan, or the Aveeno body oil adds a second layer. It softens the hair and helps the razor glide without tugging.

Habit 5: Moisturize Daily (Yes, Even On Non-Shave Days)
Dry, tight skin makes it harder for a regrowing hair to break through the surface. Moisturizing every day keeps the skin over each follicle soft enough to let the tip out.
CeraVe Daily Moisturizing Lotion has ceramides and hyaluronic acid and no fragrance. It's plain, it's cheap, and it doesn't fight the acids you use on other days.

Habit 6: Physical Exfoliation, Once A Week Max
Physical exfoliation adds to the acid, so keep the BHA wash going. The beginner exfoliation guide walks through the full texture ladder.
For ingrown prevention, a Korean exfoliating mitt used while the BHA wash is on your skin does both jobs at once. Skip the sugar scrub on that day, since the grains are abrasive enough on their own.
Mitt or sugar scrub?
Both exfoliate. One is better for ingrown prevention.
Habit 7: Post-Shave Tend-Skin Or Glycolic Toner
Tend Skin is the classic post-shave for razor bumps, with acetylsalicylic acid and alcohol. It works for a lot of people, but the alcohol stings on fresh groin skin.
A salicylic or glycolic toner without alcohol does a similar job more gently. Swipe it on with a cotton round after the shower, then moisturize once it dries.
Most guys shave, towel off, moisturize, and get dressed. A toner swipe between the towel and the moisturizer takes about 15 seconds. Count it as one of your 2-3 acid days that week.

How to Get Rid of an Ingrown Hair You Already Have
An ingrown hair is a small red bump where you shaved, waxed, or trimmed, sometimes with a dark hair visible under the skin. A pimple usually shows up where you normally break out, like the face, back, or shoulders.
Hold a warm, damp washcloth on the bump for five minutes, once or twice a day. The AAD notes that warmth helps loosen hairs that have curved back into the skin.

After the compress, a salicylic acid wash or toner on the area helps loosen the dead skin sitting over the hair. Keep moisturizing and give it a few days.
The AAD says never to pluck a hair that's trapped in a razor bump. Digging with tweezers can scar the skin. See a doctor if the bump turns hot, swollen, or very painful, since that can mean infection.
Bumps can leave a dark mark for weeks after they heal, especially on darker skin. Sunscreen on the spot and a niacinamide serum help it fade, and our exfoliating guide covers the gentle acids that speed things up.
When Ingrown Hair Prevention Isn't Enough
Some people, especially men with curly or coarse body hair, keep getting ingrowns even with a solid routine. The AAD notes that coarse, curly hairs cut short can curve back into the skin.
Two ways out: shave less, or remove the hair at the root. Our IPL hair removal guide covers the at-home option, and a dermatologist can talk you through laser.
If you'd rather skip the razor without going to laser, a body trimmer like the MANSCAPED Lawn Mower 3.0 Plus leaves a little length above the skin, so the tip can't curl back in as easily. It works well on the chest, stomach, and groin.

Frequently Asked Questions
Stack the habits: a salicylic acid (BHA) wash two or three times a week, shaving in the direction the hair grows, a fresh blade every 5-7 shaves, warm water before the razor, and daily moisturizer. If bumps keep coming after three months, laser or IPL removes the hair at the root.
Hold a warm, damp washcloth on it for five minutes, then apply a salicylic acid wash or toner. Repeat once or twice a day. Don't pluck or dig at it, and see a doctor if it turns hot, swollen, or very painful.
A salicylic acid body wash such as CeraVe SA Body Wash. Salicylic acid is oil-soluble, so it gets into the follicle and loosens the dead skin that traps regrowing hair. Use it two or three times a week, not daily.
Give a new routine about a month before judging it, since hair regrows on a cycle and older trapped hairs still surface. If you're still getting regular bumps after three months, change the method: trim instead of shaving, or look at laser or IPL.
