What causes itchy underarms?
Itchy underarms or armpit rashes can develop due to a lot of reasons, these can range from daily lifestyle habits to medical conditions. You may constantly feel like scratching your skin, this will only make the condition worse. Trying to understand the cause of the itching will help you prevent it.
While spraying deodorant before going out will help you stay fresh and smelling good for a long time, it is also the number one cause of an armpit rash. If your underarm area gets particularly itchy after applying deodorant, you may be allergic to the product or an ingredient in it. Try switching to a different brand or range, deodorants that contain alcohol can be harsh on the skin and cause itching. Therefore, it is recommended to use an alcohol-free deodorant to keep itchy underarms at bay.
Using a razor to get rid of underarm hair seems like the most convenient method. But razors may cause itching and armpit rashes. Especially if you use an old razor or your skin is sensitive and if it’s not been cleaned properly before shaving. Dry shaving can also irritate the underarm area and lead to itchy underarms. Therefore, avoid using a razor if possible and if you have to, then apply some conditioner on the area before shaving. Don’t forget to moisturise the skin afterward.
Regular soaps contain harsh chemicals and artificial fragrances, both can make the underarm area dry and flaky. In some cases, it may even cause itching and rashes. Using a pH-balanced soap or shower gel with mild and moisturising ingredients can help relieve the problem.
Sometimes internal issues may also cause a physical reaction. If you are stressed or anxious, your nervous system gets affected and this can cause itching in any part of your body. Since the underarm area is sensitive and delicate, an armpit rash may develop.
5. Poor hygiene
It is necessary to keep the underarm area clean and fresh. Apart from showering every day, it is also important to change your undergarments and clothes especially after working out. Keeping sweaty clothes on your body for a long time can cause both itchy underarms as well as armpit rash.
Types of armpit rashes
There are different types of armpit rashes that can develop in the underarms area and cause it to itch. Knowing which type of rash it is will help address the condition better. Let’s take a look at all the different types of armpit rashes below:
1. Atopic dermatitis
One type of armpit rash is atopic dermatitis also known as eczema. It usually begins during childhood and commonly develops in skin folds such as the back of the knee, inside of the elbows and the armpits. Atopic dermatitis can be very itchy and leads to red rashes that can also bleed due to excessive scratching.
2. Contact dermatitis
As the name suggests, contact dermatitis appears when your skin comes in contact with an allergen. Certain ingredients in your deodorant or body lotion may cause an allergic reaction on the underarm area. At times, certain fabrics or detergents can also trigger contact dermatitis.
3. Seborrheic dermatitis
Unlike atopic dermatitis which occurs due to dryness, seborrheic dermatitis is a result of excessive sebum production or oil secretion. It may turn your armpit area into yellow oily patches.
Candidiasis is a type of fungal infection that occurs due to poor hygiene, tight clothing and hot weather. It develops on the moist areas of the body such as the underarm area. This type of armpit rash appears in the form of red and scaly skin.
