TikTok users are participating in a new trend called 'hair training'.
The trend involves going 30 days without washing hair to achieve healthier locks.
Some people claim that this method helps to balance the scalp's natural oils and improve hair health
However, experts warn that going too long without washing hair can lead to buildup of dirt, oil, and bacteria
It's important to find a hair washing routine that works for your hair type and lifestyle.
Other factors such as diet, stress, and genetics also play a role in hair health.
Overall, while the 'hair training' trend may work for some people, it's not a one-size-fits-all solution for healthy hair.
