While there aren't specific shampoos that cause acne, there are some common ingredients that do, the biggest culprits being sodium lauryl sulfate, petroleum byproducts and many commonly used moisturizing oils such as olive oil, coconut oil and jojoba oil. Teen Vogue suggests using hair products that are as natural as possible with very minimal ingredients, and experiment with different shampoos to see how they might affect your individual skin type.
Along with sodium lauryl sulfate, other common harsh detergents to avoid include sodium laureth sulfate and ammonium lauryl sulfate, as these can irritate sensitive skin. Shop for a sulfate-free shampoo or one that contains the much milder cleansers sodium lauryl sulfoacetate and sodium lauryl sulfosuccinate. Try to avoid oils in hair care products as well. Eliminating the harsh sulfate detergents allows your scalp to create the natural oils your hair needs for moisture and shine. Additionally, wash hair only two to three times a week, but do not go to bed with dirty or greasy hair. Keep pillowcases clean, switching them out often or even investing in a silk pillowcase. Women should keep their hair in a bun or ponytail at night or during workouts, and they should style their hair prior to applying makeup. Men and women should wash their hair after heavy sports or outdoor activities.
