Ingrown Hairs: Causes, Prevention, and Treatment

Ingrown hair is more than just an occasional skin irritation for many people. It can become a recurring issue that causes pain, bumps, redness, itching, dark spots, and, in some cases, scarring. Ingrown hairs often appear after shaving, waxing, threading, plucking, or other hair removal methods, which can make regular grooming uncomfortable instead of simple.

Although occasional ingrown hairs may heal on their own, regular flare-ups often point to certain hair removal habits, hair texture, skin sensitivity, friction, or dead skin buildup around the follicle. Learning what causes ingrown hairs and how to prevent them can help reduce irritation, protect the skin, and lower the risk of future bumps.

In Dubai, where regular shaving, waxing, beachwear, gym routines, swimming, and frequent salon grooming are common parts of daily life, recurring ingrown hairs can become especially frustrating in areas such as the face, neck, underarms, bikini line, legs, chest, and back.

In this blog, we will explain what causes ingrown hairs, why some people experience them more often than others, how to prevent them safely, and when professional treatment may be helpful.

Quick Answer: Why Do Ingrown Hairs Happen?

Ingrown hairs happen when a hair curls, grows sideways, or re-enters the skin instead of growing outward. They are more common after shaving, waxing, threading, or plucking, especially in people with curly, coarse, or thick hair.

They can usually be reduced by improving hair removal technique, exfoliating gently, moisturising the skin, avoiding repeated friction, and considering longer-term hair reduction options when ingrown hairs keep returning.

Why Do Ingrown Hairs Develop in the First Place?

Ingrown hairs occur when hair grows back into the skin instead of pushing through the surface. This usually happens after cutting or removing hair, especially when the regrowing hair has a sharp edge or naturally curls back toward the skin.

Instead of growing outward, the hair may bend sideways within the follicle or re-enter the skin. The body then reacts with inflammation around the follicle.

This usually creates a small raised bump that may feel tender, itchy, or painful. In some cases, the hair may remain beneath the skin. In other cases, redness, swelling, or pus may develop if bacteria enter the irritated follicle.

Although ingrown hairs can appear anywhere on the body, they are most common in areas that undergo regular hair removal, such as the face, neck, underarms, bikini line, chest, legs, and pubic area.

Who Is Most Likely to Experience Ingrown Hairs?

Anyone can develop ingrown hairs, but some people are more likely to experience them because of hair texture, grooming habits, or skin conditions.

One of the most important factors is hair texture. Curly, coarse, thick, or tightly coiled hair is more likely to bend as it grows, making it easier for the hair to become trapped under the skin.

Frequent hair removal also increases the chance of ingrown hairs. Daily shaving, waxing at short intervals, threading, plucking, or repeatedly removing hair from sensitive areas can place ongoing stress on the hair follicles. Over time, this irritation may make ingrown hairs more frequent.

Skin condition also plays an important role. Dead skin buildup around the follicle can block the hair opening and force the hair to grow under the skin rather than through it. Tight clothing after shaving or waxing can add friction and press the hair back toward the skin.

In some cases, frequent ingrown hairs can develop into a condition called pseudofolliculitis barbae. This is most often seen around the beard and neck area, but similar follicle irritation can occur in other areas of the body.

The Everyday Habits That Make Ingrown Hairs Worse

Small grooming habits can increase the risk of ingrown hairs, especially when they irritate the follicle or cut hair too close to the skin.

One of the most common mistakes is shaving too closely. Although a very close shave may feel smoother, cutting hair below or very near the skin surface can make it easier for the new hair to become trapped when it grows back.

Dull razors can also create problems. A blunt blade may pull the hair or cut it unevenly instead of making a clean cut. Dry shaving or shaving without enough gel, cream, or water can increase friction and irritation.

Doing multiple passes with the razor over the same area can further weaken the skin barrier and increase follicle irritation. Shaving against the direction of hair growth may also increase the risk, especially for people with curly or coarse hair.

Another common error is picking, squeezing, or digging at ingrown hairs. Although this may seem like the quickest way to remove the hair, it can push bacteria deeper into the skin, increase inflammation, and raise the risk of infection, dark marks, or scarring.

How to Prevent Ingrown Hairs Before They Start

Preventing ingrown hairs starts with reducing friction, keeping the follicle opening clear, and avoiding hair removal methods that repeatedly irritate the skin.

Before shaving, wash the area with warm water to soften both the skin and the hair shaft. Applying a moisturising shaving gel or cream allows the blade to glide more easily and reduces friction against the skin.

During shaving, move the razor in the direction of natural hair growth rather than against it. This may not create the closest shave, but it can significantly lower the risk of hair curling back into the skin.

Regular exfoliation also plays an important role in prevention. Removing excess dead skin cells helps keep hair follicles clear and allows new hairs to grow through the skin instead of becoming trapped beneath it.

Chemical exfoliants containing ingredients such as salicylic acid or glycolic acid may help some people because they remove dead skin more evenly than aggressive scrubbing. They should be introduced carefully, especially for sensitive skin or areas prone to irritation.

Moisturising after hair removal helps maintain the skin barrier and reduces dryness that can contribute to irritation. Choosing breathable clothing after shaving or waxing also reduces friction while recently treated skin settles.

In Dubai’s hot weather, sweat and friction can make freshly shaved or waxed skin feel more irritated. Wearing loose, breathable clothing after hair removal and avoiding intense heat, heavy workouts, saunas, and swimming immediately after waxing or shaving may help reduce flare-ups.

What to Do When an Ingrown Hair Becomes Painful

When an ingrown hair becomes painful, the goal is to reduce inflammation and avoid further trauma to the skin.

Even with good prevention habits, ingrown hairs can still develop from time to time. Applying a warm compress several times a day can soften the surrounding skin and may encourage the trapped hair to move toward the surface.

Keeping the area clean also reduces the risk of bacterial infection while supporting the body’s natural healing process. Avoid shaving, waxing, or picking over the irritated area until the skin has settled.

Products containing salicylic acid or glycolic acid may help remove dead skin cells around the follicle in some cases. A dermatologist or skincare professional may also recommend topical retinoids, anti-inflammatory treatment, or antibiotics when appropriate.

Although it can be tempting to remove the hair immediately, digging beneath the skin with tweezers or needles can cause additional trauma. This may increase inflammation, delay healing, and raise the risk of pigmentation or scarring.

When Home Remedies Aren’t Enough

Most mild ingrown hairs improve with careful self-care, but persistent, painful, or infected bumps should be assessed professionally.

Pain that continues to worsen, spreading redness, increasing warmth, swelling, or pus may indicate an infection that requires medical evaluation. Repeated ingrown hairs in the same location may also signal ongoing follicle irritation that simple home care cannot resolve.

Some people develop firm cyst-like bumps beneath the skin or experience lingering dark marks after each flare-up. These complications may require professional treatment to reduce inflammation and minimise long-term skin changes.

You should consider professional advice if ingrown hairs:

• Keep returning in the same area
• Become increasingly painful
• Show pus, warmth, or spreading redness
• Leave dark marks or pigmentation
• Cause scarring or skin texture changes
• Interfere with shaving, waxing, clothing comfort, or daily routines
• Appear frequently after salon waxing or regular grooming

Seeking advice early can help prevent a minor skin concern from becoming a more persistent problem.

Can Laser Hair Removal Help Prevent Recurring Ingrown Hairs?

Laser hair removal may help reduce recurring ingrown hairs by reducing future hair growth from the follicle.

People who continue to develop ingrown hairs even after improving shaving technique, exfoliation, and aftercare may benefit from longer-term hair reduction. Instead of treating each bump one by one, laser hair removal targets the hair follicle to reduce regrowth over time.

With fewer active hairs growing back after shaving or waxing, there are fewer opportunities for hairs to curl into the skin. This is why laser hair removal is often considered for people who regularly develop ingrown hairs after shaving or waxing, especially when the hair is dark, coarse, or curly.

Results depend on several factors, including skin type, hair colour, hair thickness, body area, and consistency with treatment sessions. Most people need multiple sessions because hair grows in cycles.

Laser hair removal does not treat an active infection and may not be suitable for every skin or hair type without assessment. A professional consultation helps determine whether laser hair removal is appropriate and how treatment should be planned safely.

For patients in Dubai, laser hair removal may be especially useful when recurring ingrown hairs affect areas that are frequently shaved or waxed, such as the underarms, bikini line, legs, face, neck, chest, or back.

When Should Recurring Ingrown Hairs Be Professionally Assessed?

Recurring ingrown hairs should be assessed when they keep returning, leave dark marks, become painful, or affect regular grooming comfort.

Ingrown hairs are common, but they are not something you simply have to live with when they keep returning. Consistent exfoliation, proper shaving technique, moisturising, and thoughtful aftercare can reduce many cases, but repeated flare-ups may need a more structured plan.

A professional assessment can help identify whether the issue is linked to hair texture, shaving technique, waxing frequency, follicle inflammation, skin sensitivity, friction, or the hair removal method itself.

At The Nova Clinic in Dubai, patients with recurring ingrown hairs can be assessed for suitable treatment options, including skincare support and laser hair removal where appropriate.
