Yes, you can get ingrown hairs on your scalp. They’re especially common among people who shave their heads, but they can happen to anyone. The scalp is one of the more likely spots for ingrown hairs to develop, particularly if you have thick or curly hair that tends to curl back into the skin after it’s cut or broken off.
How Ingrown Hairs Form on the Scalp
An ingrown hair happens when a hair that’s been cut, shaved, or broken off grows back into the skin instead of rising straight out of the follicle. The tip of the hair curves and re-enters the surrounding skin, forming a small loop beneath the surface. Your body treats this re-entry like a foreign invader, triggering an inflammatory response around the trapped hair.
On the scalp, this process works the same way it does on the face or neck. When you shave your head, the blade creates a sharp tip on each hair. If that sharp tip curls as it regrows, it can pierce back into the skin. Waxing or tweezing can also cause ingrown hairs by breaking the hair below the surface, allowing it to grow at an odd angle on its way back out. Even without hair removal, follicle damage from tight hairstyles, hats, or helmets worn for long periods can redirect hair growth inward.
What a Scalp Ingrown Hair Looks and Feels Like
Scalp ingrown hairs typically show up as small, swollen bumps that may itch, sting, or feel tender to the touch. Because they’re hidden under your hair, you’ll often feel them before you see them. The bumps can look like tiny blisters or pus-filled spots, and the skin around them may appear darker than the surrounding area. In some cases, you can see the hair itself curving in a loop just beneath the surface.
If the bump becomes infected, it will grow larger, more painful, and may fill with pus. Infected ingrown hairs on the scalp can be easy to confuse with folliculitis (a bacterial infection of the hair follicle) or even acne. The key difference is that with an ingrown hair, the trapped hair is driving the inflammation. Without the hair being freed, the bump won’t resolve on its own.
Who Gets Them Most Often
People with thick or curly hair are significantly more prone to ingrown hairs because their hair’s natural curl pattern makes growth direction less predictable. The tighter the curl, the more likely the hair is to loop back into the skin after being cut. This is the same mechanism behind pseudofolliculitis barbae, a condition common on the face and neck that also affects the scalp in people who shave their heads regularly.
Your risk also increases if you frequently remove hair from your scalp by any method, or if you’ve had ingrown hairs before. People with a history of repeated ingrown hairs are more likely to develop ingrown hair cysts, which form deeper under the skin and can be more painful and harder to treat at home. The Cleveland Clinic lists the scalp as one of the more common locations for these cysts.
Treating Scalp Ingrown Hairs at Home
Most ingrown hairs on the scalp resolve with consistent home care over a week or two. The goal is to reduce inflammation, soften the skin, and help the trapped hair work its way to the surface.
- Warm compresses: Apply a warm, damp cloth to the bump for 10 to 15 minutes daily. This softens the skin and encourages the hair to emerge on its own.
- Chemical exfoliants: Products containing salicylic acid or benzoyl peroxide help dissolve dead skin cells sitting on top of the ingrown hair, giving it a path out. Dermatologists recommend using these as spot treatments twice a day.
- Hydrocortisone cream: Over-the-counter hydrocortisone (1% is the strongest available without a prescription) can reduce itching and inflammation while you wait for the hair to surface.
- First-aid ointment: If the area looks red and inflamed, a topical antibiotic ointment can help prevent or manage mild infection.
What you should not do is dig the hair out yourself. Even if you can clearly see it beneath the skin, attempting extraction with tweezers or a needle at home risks pushing bacteria deeper into the follicle and causing a worse infection. Dermatologists remove stubborn ingrown hairs in-office using sterile instruments for exactly this reason. Also skip DIY remedies like apple cider vinegar, rubbing alcohol, hydrogen peroxide, and abrasive scrubs. These can worsen irritation and slow healing.
Preventing Ingrown Hairs When Shaving Your Head
If you shave your head regularly, a few adjustments to your routine can make a noticeable difference. Always shave with a sharp, clean blade. Dull razors require more pressure and passes, which cuts hair at a sharper angle and increases the chance of it curling back in. Shave in the direction your hair grows rather than against it. Going against the grain gives a closer shave but leaves a sharper hair tip just below the skin surface.
Wet your scalp with warm water before shaving to soften the hair, and use a moisturizing shave gel or cream rather than dry-shaving. After shaving, rinse with cool water and apply a gentle, fragrance-free moisturizer. Regularly using a mild chemical exfoliant containing glycolic acid or salicylic acid between shaves helps keep dead skin from trapping new growth. If ingrown hairs are a recurring problem, consider switching to a trimmer that doesn’t cut as close to the skin, or spacing out your shaves to give your scalp more recovery time.
Possible Complications
Most scalp ingrown hairs are a temporary nuisance, but repeated or severe cases can lead to real problems. Infected ingrown hairs can cause scarring, especially if you pick at them or if the infection goes deep into the follicle. On the scalp, this scarring can damage hair follicles permanently. Research published in the journal Skin Appendage Disorders found that ingrown hairs are a recurring feature in several types of scarring alopecia, conditions where inflammation destroys follicles and causes permanent hair loss. The study noted ingrown hairs appearing alongside conditions like acne keloidalis nuchae (a scarring condition on the back of the scalp) and folliculitis decalvans.
This doesn’t mean every ingrown hair will cause permanent damage. But if you notice bumps on your scalp that keep coming back in the same area, are spreading, or haven’t improved after two weeks of home care, it’s worth having a dermatologist take a look. Seek care sooner if you develop a fever, notice rapidly spreading redness, or feel generally unwell, as these are signs of a more serious infection that needs medical treatment.
