Ingrown Hair

Overview

Sometimes, a hair that's been removed, like when you shave, tweeze, or wax, can grow back and curve into the skin. This is called an ingrown hair. It creates small, irritated bumps on the skin that can be uncomfortable or even painful. Ingrown hairs are more common in people with curly hair, particularly Black individuals, who often shave.

Most ingrown hairs will clear up on their own. To prevent them, you could try not removing the hair at all, or shaving less closely. If you need to remove hair, there are other methods like waxing, sugaring, or laser hair removal that might be less likely to cause ingrown hairs. These methods can help to avoid the problem.

Symptoms

Ingrown hairs are small, irritated bumps that happen when a hair curls back into the skin instead of growing out. They often appear after shaving, tweezing, or waxing. Here's what to look for:

  • Visible bumps: You'll see small, raised areas where you removed hair. Sometimes these look like tiny blisters or are filled with a bit of white or yellow fluid (pus).

  • Changes in skin color: The bump might be a darker shade than the surrounding skin. This is called hyperpigmentation.

  • Discomfort: You might feel a burning or stinging sensation, or notice itching around the bump.

  • Hair loops: Sometimes, the hair isn't just growing straight out. The tip of the hair bends and grows back into the skin, creating a loop-like shape.

A single ingrown hair isn't usually a big deal. But if you have recurring ingrown hairs, or if the bumps and discomfort don't go away, it's a good idea to see a doctor. They can help figure out the cause and recommend the best way to treat it.

When to see a doctor

A single ingrown hair isn't usually a serious concern. If you get ingrown hairs frequently or if the problem doesn't go away on its own, it's a good idea to see a doctor.

Causes

Ingrown hairs happen when a hair that's been removed, like from shaving, tweezing, or waxing, grows back and gets trapped under the surface of your skin. It curves back into the skin instead of growing out.

This often happens because of how your hair grows. If your hair follicles are naturally curved or produce tightly curled hair, it's more likely that the hair will bend and go back into the skin after being cut. Shaving, in particular, gives the hair a sharp edge that can easily pierce the skin.

Other factors that can lead to ingrown hairs include:

  • Pulling the skin while shaving: If you pull on your skin too tightly when you shave, you can force the hair back into the skin.
  • Tweezing: Even when done carefully, tweezing can sometimes lead to ingrown hairs.

When a hair gets trapped under your skin, your body reacts to the foreign object by becoming irritated. This irritation can cause redness, swelling, and sometimes even a small bump or pimple.

Risk factors

One of the most common causes of ingrown hairs is tightly curled hair. This is because the hair often curls back into the skin instead of growing straight out. When this happens, the hair can become trapped beneath the surface, leading to irritation, redness, and sometimes infection. Other factors can contribute to ingrown hairs, but having tightly curled hair is a significant one.

Complications

Curly beards can sometimes cause a skin problem called razor bumps, or pseudofolliculitis barbae. This happens when shaved hairs curl back into the skin and get trapped. This trapped hair irritates the skin, causing inflammation.

If these razor bumps aren't treated, they can lead to several issues:

  • Infection: If you scratch the irritated areas, bacteria can get into the skin, causing an infection.
  • Darker skin patches: Inflammation can sometimes leave behind patches of skin that are darker than the surrounding skin. This is called post-inflammatory hyperpigmentation.
  • Raised scars: In some cases, the irritation can lead to raised scars that are darker than the surrounding skin. These are called keloids.
  • More razor bumps: Left untreated, razor bumps can worsen, leading to more bumps and continued irritation. This cycle can be difficult to break.
Prevention

Ingrown hairs are a common skin problem. Avoiding shaving, tweezing, and waxing can help, but if you must use these methods, here's how to minimize ingrown hairs:

Shaving:

  1. Prep your skin: Before shaving, wash your face with warm water and a gentle cleanser. This removes dirt and oil that can clog pores. A warm, damp cloth can also help soften the hair.

  2. Soften the hair: Apply shaving cream or gel a few minutes before shaving. This makes the hair more pliable and easier to cut. A warm, damp cloth can also help soften the hair.

  3. Use a sharp razor: A dull razor is more likely to pull and tug on the skin, leading to ingrown hairs. Make sure your razor is sharp and use a single-blade razor if possible.

  4. Gentle shaving: Avoid pulling the skin taut. It's important to shave gently.

  5. Shave with the grain: Shave in the direction your hair grows. This reduces the risk of cutting the hair at an angle that can cause it to curl back into the skin.

  6. Rinse often: Rinse the razor after each stroke to prevent buildup of shaving cream and hair.

  7. Cool and soothe: After shaving, rinse your skin and apply a cool, wet cloth for about five minutes. Then, use a soothing aftershave balm or a lotion containing glycolic acid. Glycolic acid helps exfoliate, removing dead skin cells that can block hair follicles.

Other Hair Removal Methods:

  • Electric razors or clippers: Use these tools to avoid the closest shave setting. Holding the razor or clippers a little further from your skin reduces the risk of irritation.

  • Chemical hair removers (depilatories): These products use chemicals to dissolve hair. Because these products can irritate the skin, always test a small area of skin first to check for any allergic reactions. Follow the product instructions carefully.

By following these tips, you can significantly reduce the likelihood of ingrown hairs, and enjoy a smoother, healthier-looking complexion.

Diagnosis

Doctors usually diagnose ingrown hairs by examining the affected skin and asking about how you remove hair.

Treatment

To manage ingrown hairs, avoid shaving, tweezing, or waxing for a period of one to six months. This allows the skin to heal. If you need to trim your beard, use scissors or an electric razor. Don't resume shaving until the skin is completely clear of ingrown hairs. These steps help control the problem, but they won't permanently get rid of it.

If you can't avoid hair removal methods for that long, or other home remedies aren't working, your doctor might suggest medicine, laser hair removal, or both.

Your doctor might prescribe medications to help. These can include:

  • Medications to remove dead skin cells: A nightly cream containing retinoids (like tretinoin, found in Renova or Retin-A) helps remove dead skin cells (exfoliate). You might notice improvement in a couple of months. Retinoids can also help reduce any dark spots that ingrown hairs might cause. A lotion containing glycolic acid can help straighten the hair follicles, reducing the chance of hairs growing into the skin.

  • Creams to soothe the skin: Steroid creams can help reduce redness, itching, and inflammation.

  • Creams or pills for infections: Antibiotic creams treat minor infections that might result from picking or scratching. More serious infections may require oral antibiotics.

  • Creams to slow hair growth: A prescription cream called eflornithine (Vaniqa) can decrease hair regrowth when used in combination with other hair removal methods, such as laser therapy. Using Vaniqa on its own won't make the hair disappear, but it can help reduce the rate at which it grows back.

Your doctor might also recommend laser hair removal. Laser treatments target hair follicles at a deeper level than traditional methods like shaving, waxing, or tweezing. This can lead to slower hair regrowth, providing a more long-term solution. However, laser treatment does have potential side effects. These can include blistering, scarring, and changes in skin color (like discoloration). Be sure to discuss these potential side effects with your doctor.
