I do the same thing as Pan. I play with my hair whenever it's down. I usually wear it up in a bun for this reason...and to protect it from other things, of course.
And I'll admit to another problem as well: my boyfriend.

As a construction worker who was raised by wolves, things like delicacy and gentleness are foreign concepts to him. He is
very rough with my hair, which all stems from carelessness and obliviousness.
On a daily basis, my hair will sometimes get pinned under his elbow when we're lying down together or caught between his arm & torso. He will often drag his arm heavily across my hair...not intentionally, of course. He is naturally just a bull in a china shop and sometimes I either forget to take precautions against him or just can't. It's quite frustrating!

But there isn't a whole lot I
can do, aside from wearing a slumber cap whenever we lay together.
I never EVER let him brush or handle my hair in any way, however. Partly because he has never offered or tried, but mostly because I'm terrified of the potential damage that he would doubtlessly cause.
I definitely have the wrong hair type for the boyfriend that I've got. Or maybe...I've got the wrong boyfriend for the hair type that was given to me. Either way, the 2 do not get along.
*chuckle* this all reminds me of something Sherlock Holmes said once about a delicate finesse usually being the product of higher education.
