Reader question: They say you shouldn’t wash your hair that often, but shouldn’t I wash it after a workout? How can I wash it less? — @lromance16 Washing your hair is a cyclical nightmare. OK, maybe nightmare is a bit strong, but it certainly takes away from your precious sleep time and is something you just can’t seem to escape. The not-so-funny irony is that we wash our hair because it gets oily, but washing produces more oil. As frustrating as this is, you can train your hair to be less greasy by spacing out your washes. So, why do stylists say you should wait as long as possible to wash your hair? Not only does it turn hair color, make strands brittle, and promote breakage, shampooing strips the scalp of its natural oils, causing it to make even more oil to compensate. The more you shampoo, the more it overcompensates. In order to break the cycle, you must be willing to put up with some oiliness until an equilibrium is eventually established. It’s worth noting that the grease won’t cease right away, so the first few weeks will be difficult. The key is to not give up here—your patience will pay off. Also, keep in mind that what is “normal” between washes will vary depending on your hair type and texture, but these steps can help extend that number—whether it be by a couple days or a week. It’s also worth paying attention to your shampoo’s pH, which should ideally be around 5.5. Think of it along the same lines of toners and pH-balancing skincare—having a slightly acidic pH is necessary for proper skin cell turnover and functioning of enzymes needed to maintain skin hydration. Simply put, it won’t be as dry. As for temperature, washing with very hot water can contribute to a dry scalp, says Covington-Bowers. “Resist the temptation to turn up the heat and keep the shower temperature moderate or cool to preserve your natural oils.” Styling products will build up and clog the scalp, weighing strands down and creating the appearance of more oil. Give your locks a deep clean by using a clarifying shampoo (this will help control oil and extend your wash) OR scalp exfoliator two to four times a month (depending on how often you wash it). An apple cider vinegar rinse can also sub in here—according to stylists, ACV is acidic enough to restore the scalp’s pH balance and eliminate buildup, yet mild enough that it won’t strip your strands of essential nutrients. (It will also make your hair super shiny!)
