A hairdresser is warning people that an extremely common hairstyle could seriously damage hair, even leading to it falling out.
TikTok user Rachel Valentine often shares hair tips and tricks with her followers, and one video has now amassed more than 50,000 likes and thousands of comments.
While many of us are guilty of "throwing our hair up" in a messy bun to get it out of our faces, Rachel has warned it is "probably the most damaging way you can wear your hair".
