Conditioner. It has more added nutrients and oil tends to make hair greasy. Conditioner has just the right amount of oil to make hair healthy, but when you condition make sure to focus on the ends and avoid the roots. And use a leave in conditioner after every wash.
Leave in conditioners can be found in just about any beauty store, drug store, hair supply store. You may have to go through several until you find one that works with your hair. Or you can make your own leave in with your favorite conditioner!

no, using conditioner makes it soft after you use the shampoo, but if you want your hair straight i advise you to straighten it.
