Itchy Armpits

Itchy armpits are a common irritation that happens when you have the urge to scratch your skin. Itchy armpits have a variety of causes. Treatment could include taking medications, changing deodorants, managing any underlying conditions or maintaining proper hygiene.


What are itchy armpits?

Itchy armpits occur when you have the urge to scratch the skin of your underarms (axilla). It’s common for your armpits to itch. The most common reasons why your armpits itch include:

  • Sweat: Your armpits contain a large concentration of sweat glands, which makes it a place where you’ll experience sweating. Lingering sweat mingled with dead skin cells can lead to inflammation and eventually itchy armpits. Your armpits are also one of the warmest parts of your body. The combination of a warm and moist environment makes your underarms a place where bacteria and fungus like to grow. Bacteria and fungi growth cause itchiness.
  • Hair: Armpit hair begins growing during puberty. Another term for armpit hair is axillary hair. Hair growth can irritate your skin and cause it to feel itchy.
  • Frequent contact: The skin of your underarms frequently touches the skin on the side of your body when you have your arms down. When you wear a shirt, the material makes contact with your underarms. Frequent contact between your skin and clothing can irritate and make you feel itchy.

With itchy armpits, you may experience additional symptoms like a rash on your skin or you might not have any other symptoms. Some people experience itchy armpits during certain activities or when they’re resting at night. Everyone’s body is different. If you have itchy armpits and you’re unsure what’s causing your symptom, contact a healthcare provider.
