While it may not be pleasant, itchy underarms are an unfortunately common condition to have. Medically, having itchy armpits is known as pruritus. When you experience itching, you may also have symptoms like swelling, scarring, soreness, redness or flaking.
Initially, you will probably want to scratch your itchy armpits, but this will only make it worse. When you itch your skin, you form scratches on the skin’s surface that can become infected. While you may feel the urge to itch your underarms, you should avoid doing so. Instead, try to find out the cause of your itchiness, get an accurate diagnosis and treat it. The best way to stop the itching is to allow your underarms to heal, so no more scratching.
What Are the Potential Causes of Itchy Underarms?
While you see infomercials and media coverage about major medical problems like heart attacks and diabetes, you probably do not see anyone discussing the underlying causes of itchy underarms. You want to know why your armpits itch, but it is not always easy to find the cause. There are many potential medical conditions or lifestyle factors that can cause this condition. By figuring out what is causing your itchy armpits, you can begin to figure out the right treatment or preventative measures to take.
Your hygiene is the most common cause of itchy armpits. Bacteria loves to live in dirt and sweat, and you normally have bacteria on your skin. If you have skipped showering or spent a lot of time exercising recently, the bacteria have had the perfect environment to flourish in. Start taking regular showers every day and shower after each workout to make sure that you do not suffer from itchy armpits.
If you are female, your bra could be causing your problem. Often, there are materials in bras that you could be allergic to. Try switching to natural materials to see if it helps. You could potentially be allergic to the rubber, nickel, elastic or latex in your bra.
3. Miliaria Rubra
This medical condition is a very common disease. It is colloquially known as a heat rash. A heat rash can occur if you are in a heated, humid environment for a long time. It can also happen if you are overweight or are on bed rest. Known for being particularly common in the tropics, milliaria rubra can cause the sweat glands to become blocked so that perspiration is trapped beneath your skin. As a result, you may develop red bumps, a prickling heat sensation and itchiness.
4. Shaving Problems
One of the most common reasons for itchy underarms is how you shave. If you do not use shaving cream or have a dull razor, then your armpits may become dry and irritation. To prevent the itchiness, use shaving cream when you shave and make sure to change your razor on a regular basis.
5. Laundry Detergent
A surprising number of people are allergic to certain types of laundry detergents. If your allergy is fairly mild, you may not even notice it. Try switching to a different laundry detergent to see if the change helps your itchiness.
This common condition is essentially a rash. It happens in areas where you have skin folds like the groin, the stomach, underneath the breasts or the underarms. When you develop this condition, it can cause itchiness and redness. In severe cases, it can cause the skin to crack, ooze pus and become crusty. When the condition is left untreated, it can lead to a fungal infection or a bacterial infection. While anyone can develop this condition, it is more likely if you have diabetes, are exposed to high humidity or heat, are obese or practice poor hygiene habits.

This will also help to prevent infected or ingrown hair follicles. Practice good hygiene and make sure to avoid any allergens.
