why doesn't my hair stay curly?

After I wash my hair I have beautiful curls, but when it dries a lot of that goes away. especially if I put it in a ponytail. it just all straightens out by itself! I haven't had a perm since I was about 8/9 so I just don't understand why I can't maintain them.

Does your hair just become straight? Is the ponytail pulling the curl out? What products are you using? 
Do you let it air dry? 
If you don't put a product on your hair especially if you have 3b hair then it'll dry & become frizzy & brittle looking .. Use a good product that works for your hair. Maybe a good leave in conditoner
