Stop shaving your armpits temporarily if they're itchy or inflamed. Give the skin time to heal.

Wet your underarms before shaving to help prevent cuts and rashes from developing. Avoid shaving armpits when they're dry. Always use shaving cream or gel.

Use a sharp, clean razor each time you shave. Dull razors are more likely to cause skin irritation. In general, it's best to replace a razor after two weeks of use.

Apply an over-the-counter hydrocortisone cream to the irritated skin. It will soothe itching, redness and rashes. Use the cream for up to five days or until the rash disappears.

Wait for at least 20 minutes after shaving before putting on antiperspirant or deodorant.

Use a fragrance- and alcohol-free antiperspirant to avoid causing further irritation. If your antiperspirant makes the itching worse, switch to another one that contains different active ingredients. Alternatively, try using antiperspirant-free deodorant or crystal deodorant. When you're at home, try to skip the antiperspirant unless you really need it.

Apply a dab of moisturizer to each underarm after shaving. Use a moisturizer that contains aloe for best results.

Wear breathable garments, such as cotton T-shirts, to allow fresh air to reach your skin. Constricting clothes may cause you to sweat, leading to more skin irritation. Breathable fabrics help prevent skin from sweating as much.
