How to treat itchy underarms

There’s a good reason armpits are ticklish and sensitive; the skin under your arm is delicate, so it can easily become irritated and itchy. Whether it’s an armpit rash from sweating, or itchy underarms caused by sensitive skin, itchy armpits can be prickly, tingly and can stop us from getting the best out of our day. 

The great news is that there are as many solutions to this common problem as there are causes, so read on to find out how to stop itchy armpits.


How to stop itchy armpits – fast

Discovering the cause of your itchy armpits is key to itchy-underarm prevention, but first, find out how to stop itchy armpits fast with these quick fixes. 

  • Cool down. No matter what the cause of your itchy armpits is, a cool compress will help soothe the irritation. Press a cold, damp towel, an ice pack or even an emergency bag of frozen peas against your itchy underarms, sit down and relax for a couple of minutes. 
  • Resist the urge to scratch. Scratching an itch might be one of life’s great temptations, but it is likely to make the situation worse by breaking the skin and spreading bacteria. 
  • Wear loose clothes. Tight-fitting clothes that rub on the skin can aggravate itchy underarms. Choose a baggy, airy cotton t-shirt to give your armpits plenty of breathing space. 


Armpit rash from sweating

If armpits aren’t washed thoroughly every day, sweat and dirt can combine to form bacteria, which can result in a tingly itch. Preventing itchy underarms from sweating is as easy as 1, 2, 3. 

  1. Wash your armpits. It might sound obvious, but washing your armpits thoroughly (and gently) every day is important to avoid build-up of itchy-armpit-causing sweat and bacteria. 
  2. Dry gently. Dry your armpits by patting with a clean towel, rather than rubbing, to avoid irritating the skin. 
  3. Apply a powerful antiperspirant. If you’re exercising, choose an antiperspirant that works as hard as you do, like Degree MotionSense™. The MotionSense capsules sit on the surface of the skin, ready to burst with fragrance as soon as you move keeping you fresh, dry and comfortable. 


Itchy armpit rash from sensitive skin

If you have ruled out an armpit rash from sweating, you might have an itchy armpit rash from sensitive skin. Sensitive skin is prone to rashes, burning sensations and dryness, which can be particularly itchy in the armpit area, where it can rub and become irritated. Follow these steps to help relieve your itchy underarms caused by sensitive skin, so you can feel ready to take on the day. 

  • Use a gentle antiperspirant. Some ingredients can irritate delicate underarms and cause itchy armpits. Deodorant that has a mild formula is best for sensitive skin, so opt for one such as Degree Dry Spray.
  • Be smart when it comes to hair removal. The delicate surface of sensitives skin can become irritated by hair removal, so go easy on your armpits. Always use a (preferably fragrance-free) moisturizing shaving cream and be sure to wax carefully, avoiding skin contact with the product.  
  • Choose your detergent carefully. If you have sensitive skin, certain laundry detergents can make itchy underarms worse. Use a detergent that’s low in fragrance, and ensure that your clothes are rinsed out thoroughly.  

If you have persistent redness, swelling or itchiness in the underarm area, seek treatment advice from your GP.
