From hair stylists to dermatologists, experts now agree that hair does not need to be shampooed everyday. However, a recent movement in hair care has taken this to the extreme. The theory behind the ‘No Poo’ (no shampoo) Method is that the synthetic chemicals found in traditional shampoos damage hair by removing natural sebum. Sebum is the oily secretions from the scalp that protects and moisturizes the skin. It makes hair feel greasy.
Your scalp responds to frequent shampooing by producing excess sebum, making hair feel even greasier. Then you need more shampoo for hair to feel clean, and the cycle continues. Proponents of the ‘No Poo’ Method believe they can break this cycle by using gentler options, including baking soda, apple cider vinegar, and even water alone. These alternatives purportedly have the same effect as shampoo, but are much milder. The idea is that persistent use can result in your scalp producing less sebum and hair will become less greasy.
Although some believe that the ‘No Poo’ Method is a better alternative to shampoo, outside of testimonials from celebrities like Kim Kardashian, there is no evidence to support this belief. That being said, the ‘No Poo’ Method isn’t detrimental. How you choose to wash your hair is a personal choice, as neither choice will drastically affect your health. Frequency of hair washing is also largely preferential, but people who sweat a lot, have very fine hair, or a naturally oily scalp might consider daily washing if it helps to limit itchiness, dandruff, and head acne
