How to Get Rid of Armpit Rash

An armpit rash (or underarm rash) is often unpleasant. There might be pain, burning and itching of the affected skin, which is already tender. The rash can also be embarrassing in certain situations. There are many causes of armpit rash and different treatments for each cause. Armpit rash can be the result of a perfume or deodorant you are wearing, excessive heat, sweat and grime, a soap product you are using, or even the clothes that you wear.

In most cases it might be difficult to determine or diagnose the exact reason causing the armpit rash, but in the absence of any underlying medical condition, the most common cause for a typical armpit rash is usually lifestyle alterations.

Symptoms of armpit rash might include itching, rash, dark underarms, flakiness, pain and increased odor. If you experience armpit rash, learn how to recognize and heal the condition.

You can heal armpit rash with home remedies if you are confident as to its cause, but it should be checked out by a doctor if symptoms persist or worsen over time. Read on to learn how to get rid of armpit rash.

How to Get Rid of Armpit Rash

Help Soothe the Rash

If you’ve developed armpit rash, it’s time to help soothe the rash, first and foremost. Follow these steps to help soothe the rash.

  • Wear loose fitting clothing made of natural materials such as cotton, jute and linen. These materials will help your skin breathe easier, cutting down on the chance of folliculitis.
  • Wash under your arms with mild, fragrance-free soap. Allow the area to dry thoroughly.
  • Apply a hot, moist compress to the area. The moist compress should help promote drainage. Once washcloth has been used, substitute it for another clean compress the next time you apply it.
  • Use an over-the-counter anti-fungal cream or lotion. These are the same products used for fungal infections in other areas of the body such as the feet and groin.
Stop Using Products That Irritate Your Skin

Deodorants often contain aluminum, fragrances, alcohol and parabens, all of which can trigger a rash. This is one of the easiest causes of itching or redness to eliminate.

Experiment with hygiene products by trial and error. Try switching to a fragrance-free deodorant first. If this doesn’t heal armpit rash, switch to different, preferably fragrance-free soap.

Avoid Scratching

Skin abrasions caused by scratching can lead to fungal or bacterial infection. Use a topical ointment, such as hydrocortisone, if the itching becomes unbearable.

Stop Folliculitis

Folliculitis starts when hair follicles get damaged for whatever reason, becoming infected. Luckily, this irritating condition can be avoided and treated.

  • Wash your clothes in non-irritating detergent. Refrain from using any fabric softeners.
  • Be sure that you aren’t sensitive or allergic to any certain type of material, such as wool.
  • Wear clothing that allows your skin to breathe, especially if you live in a warm climate.
  • Wear clothing that isn’t too tight in the armpit area. Rubbing can cause irritation.

Shaving can also cause hair follicles to become ingrown and even infected. Stop shaving under your arms to see if that is the cause of your irritation. Try waxing or use a hair removal agent instead until you get rid of armpit rash.

Relieve Pain and Discomfort

Apply soothing oils or lotions to the affected area to relieve pain and discomfort. An oil containing vitamin E may help, although topical vitamin E may irritate the skin of some people.

  • A mild hydrocortisone cream applied to the irritated area to help heal your armpit rash while preventing irritation and itching.
  • Calamine lotion is also a popular anti-itch cream used on rashes.
Practice Good Hygiene

The underarm area is a perfect breeding ground for bacteria and fungus because it is dark and moist. Armpit rash can be attributable to poor hygiene, but it’s far more likely that the rash is a direct result of heat, friction or contact with allergens.

Other Remedies to Get Rid of Armpit Rash

Coconut Oil

Coconut oil has many amazing uses and health benefits. When applied topically, it can help heal armpit rash.

  • Mix coconut oil and baking soda to make a paste.
  • Apply the paste to the affected area and leave it on for around five minutes.
  • After five minutes, rinse it off with cold water.
  • Try this remedy daily until you see improvement.
Aloe Vera

When it comes to getting rid of armpit rash, applying aloe vera gel is one of the best treatments you can try.

  • Apply aloe vera gel to the rash and surrounding affected areas.
  • Leave it on for around five minutes and then rinse it off with cold water.
Tea Tree Oil and Water

This combo can kill the fungus and stop itchiness when applied to the armpit rash. Use a cotton ball when applying this blend to the affected area.

Baking Soda

You can use baking soda as an armpit rash treatment. Mix 1/4 teaspoon of baking soda with a little bit of water — don’t dissolve it — and rub it under your arms. If you wish, you can also dust a little bit of baking soda and cornstarch under your arms for a drier feel.

Olive Oil

Olive oil is known to have therapeutic properties. It will penetrate the skin and heal the rash effectively.

  • Soak a cotton ball in olive oil and apply it to the affected area.
Oatmeal Bath

Try a colloidal store-bought product, or make your own oatmeal bath by wrapping one cup of oatmeal in a cotton cloth or sock and boiling as you would to cook it. Let it cool down a little bit, and use the oatmeal poultice as a sponge to bathe in.

Neem Leaves

The antiseptic and anti-bacterial properties of neem leaves help soothe the itchiness and irritation.

  • Grind some neem leaves to make a paste.
  • Then apply the paste to the affected area.
  • After five minutes, rinse it off with cold water.

The citric acid in lemon juice also kills the bacteria underneath your arms. Take a slice of lemon and swipe it under your pits for a nice natural deodorant. Just be sure not to use lemon juice immediately after you shave.


  • Rashes caused by allergies can be life-threatening. If you have other symptoms besides your rash, see a doctor immediately. These symptoms include swelling of the face or throat, difficulty in breathing, or loss of consciousness. A purple rash can be a sign that something is seriously wrong.
