Singing Carole King's "I Feel the Earth Move", the Iowa native may not have sounded like King, but her curly locks sure did resemble the 70s singer/songwriter.
Judge Randy Jackson commented on how Katelyn looked like King and even Simon Cowell said, "I like your hair." If you ask us, we have to agree with Cowell. Don't worry about what else the judges had to say -- you've locked down our vote!
Want to rock out your own curly locks? It's all in the product, celebrity hairstylist, Danielle Caputo told StyleList in an earlier interview. By starting with a spray-in conditioner and adding a good curl cream with your fingers (not a comb), you can get your hair ready for the scrunching and diffusing that comes next. The trick is to dry from roots to the ends, getting your hair right up to the diffuser.
When your hair is dry, if you decide you want more volume at the roots, just spray a little water there to reactivate the products and diffuse a bit longer. Finishing off with a light wax will help to set everything and hold those waves in place.
