Ingrown hairs are a common and often painful skin condition that occurs when hair curls back or grows sideways into the skin instead of rising through the surface. This condition can lead to inflammation, redness, and sometimes infection. Ingrown hairs most frequently appear in areas where hair is shaved, tweezed, or waxed, such as the face, legs, armpits, and bikini line. While ingrown hairs are not usually a serious medical issue, they can cause discomfort, irritation, and even scarring if not properly managed. Understanding the causes of ingrown hairs, as well as effective prevention and treatment strategies, is essential for maintaining healthy skin and preventing complications.
Causes of Ingrown Hairs
Ingrown hairs occur when hair follicles become blocked, trapping the hair beneath the skin’s surface. Several aspects can contribute to this problem:
- Improper Hair Removal Techniques
Shaving, waxing, and tweezing are the most common methods of hair removal, but when done incorrectly, they can increase the risk of ingrown hairs. Shaving too closely or using a dull razor can cause the hair to be cut at an angle, making it more likely to curl back into the skin as it grows. Similarly, waxing or tweezing can cause hair to break off below the skin’s surface, leading to ingrowth. - Curly or Coarse Hair
This type of hair naturally tends to curve as it grows, increasing the likelihood that it will re-enter the skin. This is why ingrown hairs are more common in people of African, Latino, or Middle Eastern descent, whose hair is often curly or coarse. - Clogged Pores and Dead Skin Cells
When pores become clogged with dead skin cells, oil, and debris, hair follicles may be obstructed, making it difficult for new hair to grow outward. Instead, the hair becomes trapped beneath the surface, leading to ingrown hairs. - Tight Clothing
Wearing tight clothing, especially around areas prone to ingrown hairs (such as the legs, bikini area, or neck), can contribute to ingrown hairs by pressing the hair against the skin. This pressure can force the hair to grow sideways into the skin rather than upward.

Symptoms of Ingrown Hairs
Ingrown hairs can cause a variety of symptoms, including:
- Small, round bumps on the skin (also known as razor bumps or pseudofolliculitis barbae).
- Redness and inflammation around the affected area.
- Pain, tenderness, or itching.
- Pustules or pimples filled with pus, which may indicate infection.
- Darkened skin (hyperpigmentation) around the ingrown hair, especially in people with darker skin tones.
While most ingrown hairs resolve on their own, some may become infected and form painful, pus-filled lesions. In severe cases, untreated ingrown hairs can lead to scarring or permanent changes in skin texture.
Prevention of Ingrown Hairs
Preventing ingrown hairs involves proper hair removal techniques, skincare, and hygiene practices. Here are some real tactics to decrease the risk:
- Exfoliate Regularly
Exfoliating the skin helps remove dead skin cells that can clog pores and trap hairs. Use a gentle exfoliating scrub or brush to slough off dead skin cells before shaving or waxing. This will ensure that the hair can grow outward more easily. For sensitive areas, consider using a chemical exfoliant containing alpha-hydroxy acids (AHAs) or beta-hydroxy acids (BHAs) to avoid irritation. - Use Proper Shaving Techniques
When shaving, always use a sharp, clean razor and avoid shaving too closely to the skin. Shave in the direction of hair growth, rather than against it, to minimize irritation and prevent the hair from being cut at an angle. Applying a moisturizing shaving cream or gel can also help reduce friction and protect the skin during shaving. - Moisturize the Skin
Keeping the skin hydrated and moisturized can help prevent ingrown hairs by softening both the hair and the skin. After shaving or waxing, apply a gentle, alcohol-free moisturizer or lotion to soothe the skin and reduce irritation. Products containing ingredients like aloe vera or tea tree oil can help calm inflammation and prevent infection. - Consider Alternative Hair Removal Methods
If you frequently experience ingrown hairs, you may want to explore alternative hair removal methods that reduce the risk. For example, using a depilatory cream (a chemical hair remover) can dissolve the hair at the skin’s surface without causing trauma to the follicles. Laser hair removal and electrolysis are longer-term options that permanently reduce hair growth and are less likely to cause ingrown hairs over time. - Avoid Tight Clothing
Wearing loose-fitting clothing, especially after shaving or waxing, can help prevent ingrown hairs by reducing friction and irritation. Tight clothing can trap sweat, oil, and bacteria against the skin, increasing the risk of clogged pores and ingrown hairs.
Treatment Strategies for Ingrown Hairs
If you do develop ingrown hairs, there are several effective treatment strategies to reduce discomfort and promote healing:
- Gently Exfoliate the Affected Area
Once an ingrown hair develops, gently exfoliate the area to encourage the hair to emerge from beneath the skin. Use a soft washcloth or an exfoliating brush to massage the skin in circular motions, which can help loosen the trapped hair and clear away dead skin cells. - Warm Compresses
Applying a warm compress to the affected area can soften the skin and reduce inflammation, making it easier for the trapped hair to rise to the surface. Soak a clean cloth in warm water and hold it against the ingrown hair for several minutes. Repeat this process a few times a day until the hair is visible. - Tweezing or Removing the Hair
Once the hair has emerged from the skin, you can use sterilized tweezers to gently pull the hair free. Be careful not to pluck the hair entirely, as this can further irritate the follicle and lead to recurrence. Never dig into the skin to remove an ingrown hair, as this can cause infection or scarring. - Topical Treatments
Over-the-counter creams containing salicylic acid, glycolic acid, or hydrocortisone can help reduce inflammation and promote healing. These ingredients work by exfoliating the skin and reducing redness and swelling. In cases where the ingrown hair becomes infected, an antibiotic ointment may be necessary to prevent the spread of bacteria. - Medical Intervention
In more severe cases of ingrown hairs, where the hair has become deeply embedded or infected, a dermatologist may need to intervene. They may prescribe a stronger topical or oral antibiotic to treat an infection or use a sterile needle to remove the trapped hair.

Long-Term Care and Prevention
For individuals who are prone to frequent ingrown hairs, taking consistent preventive measures is key to minimizing their recurrence. Regular exfoliation, proper shaving techniques, and keeping the skin moisturized are essential components of long-term care. Additionally, exploring alternative hair removal methods like laser treatment can provide a more permanent solution for those who struggle with chronic ingrown hairs.
In Brief:
Ingrown hairs are a common skin issue that can cause discomfort and frustration, but with proper care and prevention strategies, they can be effectively managed. By adopting good skin care habits, using appropriate hair removal techniques, and being mindful of skin hygiene, you can significantly reduce the occurrence of ingrown hairs. If ingrown hairs become painful or persistent, seeking advice from a dermatologist can help ensure that you receive the right treatment and care to keep your skin healthy and smooth.
