Are you asking how to make your hair different textures or different ways to wear your hair?
Depending on your type of hair, it may or may not be difficult to make it do what you want it to. If it’s pretty thick and wiry it will probably hold a style better than soft, fine hair. If you want curly or wavy, try scrunching your hair up with some gel and then drying it with a diffuser on a low setting. Curling irons can do the trick, too, it’s just a lot more effort, and sometimes it can come out looking pretty unnatural. To avoid that you can always comb your fingers through your hair and sort of muss it up to give it a more relaxed feel.
In terms of different ways to wear your hair, you have a lot of options with your hair as long as it is. Pony tails, braids, and all variations of these are at your disposal. Scroll through some rad hair blogs for inspiration. ;)
