I'm sick of my hair. I need advice on how to cut it/style it. I've also got quite a large forehead. What should I do? (17)

As the title says, I'm sort of sick of my hair. I've been endlessly searching around for new hairstyles, watching tutorials on how to style my hair, actually styling it and experimenting, researching hair products and seeing whether or not my forehead is large, especially how it goes quite far back in the corners.

I usually wash my hair every 3 days, and my hair is naturally wavy, but only very slightly. It's also very dry.

Finally, it would be a great help if you would say what product I should use for the style you are referring. I don't really like shiny, greasy looking hair, so a matte look is recommended.

Thanks :)
