Why doesn't the back of my hair curl like the sides of my hair?

This is actually common among women with naturally curly hair. I think we know sometimes with naturally curly hair comes frizziness. I don't think layers will help you could try Ion from Sally's it's a spray on styler it's an alcohol free gel you could scrunch the back of your hair with your hands. Or you could try Sprunch from Aussie I heard it's really good. Hope I helped God bless u and have a nice day :)
