I'm bored of my hair. I've asked this before I know but I have forgotten the advice 
I'm growing it to donate so cannot cut it into styles at the moment. It's really heavy so doesn't hold other styles very easily and I need to have it up in a simple ponytail or bun for work as the kids just pull it out every half an hour.
What can I do with it otherwise? Any easy and simple styles that will keep it out of my face and also ones that don't encourage greasiness (it greases up very quickly). It's not yet long enough for a plait given how thick it is
It's bottom of shoulder blade length.
I am shite with the straighteners, have tried curling and following tutorials and cannot get it to work. I remember a babyliss device being recommended last time?
