Curly on top, straight in the back.
I have some decent curls on the top of my head, but the back of my head is completely straight! What's going on here and how do I fix it?
I use a custom mix from Prose for shampoo and conditioner (sulfate free). Oribe Curl Gloss gel for styling and air dry after showers. For my routine, I typically wash my hair 2-3 times a week and I run my fingers through it with the conditioner on my hands to "brush" it while in the shower, but that's the only brushing I do.
I'm a pretty low maintenance person so for styling I just put some gel in my hands, flip my head upside down, and scrunch my hair (top and back). If I have the need to dress up, I will diffuse my hair, but that doesn't seem to help much with the back.
I don't wear any headbands or other hair accessories that may be flattening the hair at the back. I try to keep the hair at the back of my head short because it looks ridiculous having 2 different textures when I grow it out, but the length doesn't seem to impact the hair shape either.
