How to use flat iron: Selena Gomez's hair mistake

Singer Selena Gomez says her "biggest hair mistake" was learning to use straightening tongs when she was in the sixth grade.

"My biggest hair mistake is when I was younger and I was figuring out how to use a flat-iron.

"I used to think that just because visually I could see that this hair was straight that the back didn't necessarily have to be straight, so for the entire 6th grade I only straightened the front of my hair. That wasn't really my proudest moment," reports etonline.com.

Gomez also says her favourite hair accessory is a "scrunchie", which she likes to wear with a few strands of hair left untied.

"My favourite hair accessory is a scrunchie. I know it's kind of old school but it's really cute when you put your hair up and you let a few pieces come down. It's nice," she said.
