How Many Times Should We Wash Our Hair Per Week?

The number of times we should wash our hair is a topic of ongoing debate. There are claims that frequent washing is important, especially after returning from the gym, if you want to avoid oily and weak hair strands. Others argue that it is essential to wash hair as little as possible to maintain its health. Amidst this debate, the concept of "hair training" has emerged on TikTok, where videos about this trend have garnered more than 160 million views on the app. Thus, "hair training" involves teaching hair strands to go without washing for as long as possible, with the goal of making them healthy and long. In response to this phenomenon, hair specialist Kate Holden told The Sun that spending long periods without washing hair "may not always be beneficial." She explained that "washing our hair with shampoo is vital for maintaining cleanliness and scalp health. It removes oils, dandruff, dirt, pollution, harmful microorganisms, and residues from hair care products that can cause irritation and promote the health of dull, straw-like hair."
