How often should you wash your hair? Once a day? After a workout? Once a week? Every two weeks? When your co-workers start moving away from you? Today, Kim Kardashian West noted on her website that she only shampoos twice a week to avoid excess hair damage. While it sounds unappetizing, she’s not alone. Many people believe that washing your hair every day can cause more harm than good. It turns out that the frequency of your shower routine depends on the texture, moisture, and length of your hair, there isn’t a set rule. “Everybody’s sebaceous glands vary,” Manhattan-based colorist Lucille Javier of Sally Hershberger Downtown tells Yahoo Beauty. “In the winter, they’re more dry. In the summer, your sebaceous glands are more active because you’re sweating more.” It also depends on how often you chemically treat your hair; Javier notes that those with 100 percent natural hair shouldn’t worry about washing too often. But Kardashian West, who has dyed her hair platinum blonde before and frequently styles it for public appearance, may be wary of frequent washing. Some products that she recommended on her website to use in conjunction with low-frequency shampooing include Rodin by Recine Luxury Hair Oil ($70), Frédéric Fekkai Fekkai Brilliant Glossing Crème ($20), Olaplex No 3 Hair Perfector, Carol’s Daughter Monoi Repairing Hair Mask ($32), and Oribe Supershine Moisturizing Cream ($49).
