Different things can cause armpit hair to grow back into the skin.

Poor shaving techniques, curly hair (type of hair), some cancers and even deodorants are known to cause armpit razor burn and bumps. Below are the main causes.

1. Shaving or waxing underarms

Do you get razor bumps underarms when you shave? Shaving is a delicate issue especially for sensitive skin underarms. If you use old and blunt razors and shave in the wrong direction, you are likely to get razor bumps and ingrown hairs.

Hair removal techniques such a waxing need to be gentle too. According to SkinAcea, when you pull hair completely out of the follicles in your armpits, you are likely to change the direction of hair growth.

Epilation, waxing, tweezing and rough shaving can lead to ingrown underarm hair. To prevent them, you should change your armpit hair removal methods. Here’s how to prevent ingrown under arm hair when shaving or waxing to remove hair.

  • Shave in the direction of hair growth.
  • Do gentle waxing or epilation. Forceful removal of hair will cause boils and even infections.
  • Lather the skin well before shaving to prevent ingrown armpit hair.

2. Curly hair grows back into the skin

Studies have shown that Latinos or Hispanic and African American people have curly hair. This type of hair, especially when thick, is prone to forming ingrown hair, also called pseudofolliculitis.

This explains why razor bumps are prevalent in African American men – on the neck, jaw area, face and underarms. In summary, genetic makeup can determine whether you will be getting armpit hairs more often or not.

3. Clogged hair follicles

If you are not used to exfoliating your skin, you are likely to get ingrown armpit hair. Dead skin cells and dirt, excess sebum and other debris can clog pores and block hair follicles. This forces hair to grow back into the skin or sideways.

To prevent ingrown underarm hair from clogged pores, exfoliate your skin a few days after shaving to help the follicles to grow straight out of your skin. Here’s how to do it.

  1. Soak in warm water to allow the skin to soften
  2. Apply antibacterial soap onto a soft piece of cloth
  3. Scrub the underarm skin gently, especially the areas where you removed hair and where the underarm bumps and ingrown hair are notoriously recurring.
  4. Rinse the skin with clean lukewarm water.
  5. Pat the skin dry.
  6. Apply a good moisturizer on your skin. You can use bikini balm, which works for pubic ingrown hairs and bumps.

While exfoliating, ensure that you do not strain the skin or cause it trauma. It will worsen the bumps rather than getting rid of the ingrown hair.

4. Tight clothing and scratching

Tight clothes can also obstruct the growth of hair in your underarms. The same thing happens when you scratch underarms, especially if you are suffering from itchy armpits from razor burn. Some types of clothing such as synthetic and nylon fabrics are known to cause ingrown hair under armpit.

In order to avoid this, allow your underarms, bikini area, legs, face or any other part of your body that you shave to get free circulation of air. Clothing should not cause any friction on your underarms.

Constant deep ingrown underarm hair

Ingrown armpit hairs that won’t go away can cause discomfort and make you fear shaving. It is expected that your hairs should go away on their own, but when they remain constant, it is important to seek medical attention as the skin can remain with scars in the armpit.

Fox News, in Dec 2014, reported of the longest ingrown hair being shown in a video posted on Reddit. Sometimes, such hairs can be difficult to remove especially if you do not have the right tools such as tweezers.

In some cases, deep ingrown hair in armpit can remain in the skin for years without coming out, and may grow and curl deeper and horizontally.

These bumps look like pimples and may end up forming an abscess that is fluid-filled. If left untreated, these abscesses can form boils.
