"My biggest hair mistake is when I was younger and I was figuring out how to use a flat-iron," Sel said to ET.
"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."
LOL, we've all been there. Oh, and she still totally rocks scrunchies. Glad we aren't the only ones!
"My favorite hair accessory is a scrunchie," she added. "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."
Growing up in the business has given Sel the opportunity to pick up many hair tricks, too, and she revealed her favorite. "Dry shampoo," she said simply. "I think it's awesome."
All of this hair-talk makes sense coming from Selena. She was just signed on as a spokesperson for Pantene hair products. #GetItGirl
