I'm no help in the typing department but my hair does the same thing!

I think it's because it's getting longer(mine is currently about shoulder length) and it's pulled/weighed down a little straighter through the length but curls on the end.

I think it also might have to do with products and how they're applied. I think if I used gel which encourages curl and did some scrunching it would all curl up more into ringlets instead of waves ending in curls.

Anyway, pretty ringlet!
