A viral trend on TikTok dubbed “hair training” is gaining popularity, with individuals opting not to wash their hair for up to a month. Proponents of the trend argue that infrequent washing can train the scalp and hair to appear healthier and more attractive, asserting that it ultimately reduces the need for frequent washing.
Participants in the trend share various techniques, such as soaking roots in rosemary oil and using leave-in conditioner overnight before washing. A TikTok user, @cherries87, claimed to have abstained from washing her hair for over a month, citing the potential benefits of the practice.
While some praise the trend for purportedly promoting thick and luscious hair, skepticism abounds. Concerns are raised about the feasibility of washing hair only once a month, with comments noting greasiness and scalp itchiness after just a few days.
Experts caution against the trend, suggesting that it may lead to hair loss. Dr. Fariha Anwar, an aesthetic doctor at Euromed Clinic Dubai, warns that infrequent washing can result in the accumulation of excess sebum on the scalp, potentially leading to seborrheic dermatitis—an inflammatory skin condition. Anwar highlights that persistent scratching of an itchy scalp can contribute to hair loss.
A 2021 study published in the journal Skin Appendage Disorders adds weight to these concerns. The research, conducted by Surpriya Punyani et al. with a sample of 1,500 people in China, indicates that those who washed their hair more frequently (five to six times a week) had healthier scalps. The study suggests that infrequent washing can lead to scalp sensitivity and an increased risk of hair loss.
The American Academy of Dermatology Association emphasizes that the frequency of hair washing should be tailored to individual factors such as age, skin type, and hair texture. Recommendations range from once a week or every other week for individuals with curly and coily hair to daily washing for those with oily scalps and skin types.
This trend is not the first to spark debate over hygiene practices on social media. In 2021, TikTok users went viral for advocating showering only every two to three weeks, showcasing the ongoing divergence in opinions regarding personal care habits.
