What causes itchy armpits?

Many people suffer from the annoyance and discomfort of itchy armpits at some point in their lives. As this unsightly condition has many possible causes, it can sometimes be difficult to resolve. Understanding the most common causes of itchy armpits may be the key to avoiding or quickly relieving the condition in the future. Toiletries like deodorants and body washes are common underarm irritants, as are laundry detergents. Shaving can also cause irritation in the underarm area, as can certain bras and exposure to an allergen like poison ivy.

Toiletries such as deodorants and body washes are perhaps the most common cause of itchy armpits. Sometimes these products contain a fragrance or other ingredient that the skin is allergic to. In other cases, particular product formulations may simply be too harsh, especially for users with sensitive skin. Either way, the offending product can cause intense itching that is often accompanied by redness.

The best way to determine if a bath is causing itchy underarms is to stop using the product for several days. If the irritation subsides, it is likely caused by the product in question. The offending toiletries should be discarded, and a product formulated for sensitive skin should be used instead.

Laundry detergents can also cause itchy armpits. However, in most cases, this itching will not be limited to the underarm region, but will occur where the clothes washed with the irritating detergent touch the skin. Those who experience itchiness after switching to a new laundry detergent should substitute a different product.

Improper shaving technique can also lead to itchy armpits. Using a dull razor, as well as a lack of shaving cream, can lead to dry, irritated, and itchy underarms. To avoid shaving-related underarm itchiness, change razors frequently and always lather skin with shaving cream before waxing. Also, avoid applying deodorant or antiperspirant to your underarms immediately after shaving.

For some women, bras can cause itchy underarms. Bras often contain certain materials that some people are allergic to, such as elastic, rubber, latex, or nickel. Those who suspect that their underwear is causing their itchy armpits can try selecting bras made from natural materials.

Finally, exposure to an allergen like poison ivy can lead to itchy armpits. This irritation can be the result of direct contact with the allergen, or from contact with an object that has been exposed to the allergen. To prevent this type of underarm irritation, avoid wearing tank tops when participating in outdoor activities such as camping or hiking. Also, be sure to thoroughly wash all clothing worn during these activities to remove any lingering traces of allergens.
