How can i make my hair more beautiful?

i have a curly hair and i dont want to straighten it up! i gave up already with those treatments because it just worsen the dryness of my hair. now i love my hair as before BUT i want to improve it. i want to make my curves better coz it's quite dry, i think because of movea hair lotion that i'm using but so far this hair lotion is good coz i've tried many hair mousse before and i think this one's better. what do you think? should i try cellophane?hair spa?hot oil? or anything you would suggest regularly like every 3/6 months for my hair to make it more shiny and healthy and not dry so i could no longer use ponytail? thanks much!!!!
