1/2 head of curly hair? Perm?

[srslysarahcee]

I have naturally curly hair... except on my bottom layers. I have no idea why this is, my hair is healthy (ie. 'passes' float test), virtually no split ends either. It is just that the bottom layers of my hair, from about mid-high ear and down is absolutely pin straight while the rest is wavy/curly. Any ideas why this might be?

Also, partially because of this but also because I would love an even curl I was considering getting a loose body wavy perm (if that is possible?), have any curly haired girls tried this? How did you fair?

Thanks in advance!
