A new trend on TikTok, called “hair training,” is causing concern among experts. Influencers are encouraging their followers to wash their hair infrequently, in some cases even going weeks without washing, with the promise that it will improve the health of their hair and scalp over time. However, this practice is not supported by science and could lead to scalp issues such as itchiness, irritation, inflammation, and even hair loss due to buildup of oil, dirt, and hair care products.
While daily hair washing may be necessary for those with oily hair, others with dry hair may benefit from washing only once or twice a week. The frequency of hair washing should depend on several factors, including hair type, ethnicity, age, and level of physical activity.
It is important to note that there is no one-size-fits-all solution when it comes to hair care, and individuals should determine their hair care routine based on their unique needs. Experts caution against blindly following popular trends, especially those that promote habits that could potentially harm hair and scalp health.
