In the TikTok social network, some strange, sometimes even dangerous, "challenges" often appear.
But the latest challenge has left many speechless. A large group of social network users have started a challenge not to wash their hair for a full 30 days.
They have filmed their hair after 30 days without washing it, claiming that in this way the scalp is strengthened and the hair becomes more beautiful but also more resistant.
The hashtag #hairtraining has already received over 164.3 million views, with many videos showing TikTokers going weeks without washing their hair. Here's an example:
@kaitmoritz I went 18 days without washing my hair! My secrets to hair training are brushing and oiling your hair daily, Redken dry shampoo, and crimping your hair so it looks less oily. #GetCrackin #hairtraining #hairwashday #hairtrainingtips #hairtraining101 #hairwashingroutine #hairwashing #hairwashroutine #hairtok ♬ original sound - Kait
But is this hair training practice actually backed by any scientific evidence?
Unfortunately it is the opposite! There are reasons why you should wash your hair more often than once a month, besides the desire to have friends, successful dates and people willing to share your hats.
If you don't wash your head regularly every day things like dirt, dust, insects, oils, chips and various pollutants fall on your head. Every day, your scalp produces oil and other particles as well. All this can lead to irritation, itching, inflammation and burning of the skin. If it gets bad enough, you may start losing your hair.
