Why do the ends of my hair curl up when I airdry?

[Tene]

I co was almost daily and when I airdry my hair half of my hair on down to my ends draws up and curls up when it drys. I thought that was strange especially since my hair is relaxed. Does anyone know what could this be?

Is your hair touching your shoulders? When my hair was shoulder length, it would curl up from touching my shoulders in to this "Marlo Thomas, That Girl" look!

It's not at shoulder yet, it's near it.
