Curls at ends

Hey there, I'm new to this forum :P. What's up?
So I have quite long hair, My front hair reaches the end of my chin and I'm growing it out but a month and a half ago, I had a really light trim to remove some of my split ends but it almost regrown to just like it was before.. But Before AND After that trim, I don't know why, I have curls at the end of the back of my hair. My side bangs, My front hair and the back of my hair are like 80-90% Naturally straight and like 10% wavy. Again, I don't know why, But the ENDS at the back of my hair, (At the back, below my neck) There ends are a curly.. How and why does this happen? It doesn't have the curly ends after a shower but it does when the hair is dry from water.
Also, Will the curls be gone when my hair will grow more and weigh more down?

Thanks a lot for the help :)
