You scrub your scalp with your fingernails
A good scalp scrub can feel refreshing, but you’re actually doing more harm than good if you use your fingernails. “Your fingernails can scratch the scalp and even cause flaking,” says Sandy Johnson, MD, of Johnson Dermatology in Fort Smith, Arkansas. Instead, use your fingertips to work up a lather. It’s also important to avoid aggressively rubbing strands of hair between your hands, which can damage it and cause split ends, she says. Be sure to stop these other hair washing mistakes you didn’t know you were making.
Your soap doesn’t contain any moisturizer
“Bar soap without any moisturizing agent, like many antibacterial deodorant soaps, can really dry out your skin,” says Mona Gohara, MD, of Advanced Dermcare in Danbury, Connecticut. Look for bars with stearic acid in the ingredient list or “moisturizing” advertised below the name, says Dr. Gohara. (She uses Dove White Beauty Bar).
