Oily Hair Shampoo

Oily hair shampoo is formulated to cleanse excess sebum, sweat and styling-product buildup from the scalp. The category can include lightweight daily shampoos, balancing formulas and deeper-cleansing or clarifying products, with different options for fine, straight, coloured or sensitive hair. Concentrate shampoo on the scalp rather than repeatedly coating the full hair length, then apply conditioner mainly to the ends if they feel dry. Washing frequency should follow how quickly the scalp becomes oily; the American Academy of Dermatology notes that people with straight hair and an oily scalp may need to shampoo daily. Persistent oily flakes, itching, redness, sores or sudden hair changes should be assessed professionally.
