Help Please!

Hello this is my first post on here and I just wanted to get some help for my hair, I recently just started growing my hair out for the first time and it is a little past my ears. When ever I take a shower and I come out and i dry my hair (i use shampoo and conditioner) it is all dry and kind of frizzly and then my hair naturually curls kind of towards the bottom and I do not like it. The other day I did not put shampoo in it and my hair got greesy so it had weight to it and it would bunch together and it actually looked really good for me but the thing is I can not do that cause my hair will smell and be gross so I was wondering what could i put in my hair to add weight so it will not curl and so it will bunch together instead of single hairs everywhere please help
