My hair is between a 2C and a 3A and I wash it every day, but in the back of my hair about 4 inches from my roots to my curls, the hair is sraight. How can I get it to be curly like the rest of my hair? You should know I only just started allowing my hair to be curly about 4-6 months ago. I use aussie confidently clean shampoo and a conditioner by Great Clips.

Also, would it be good for me to get layers?

By the way I don't usually use product but I am open to suggestions.
