Please help me out!

I need to try a new brand of shampoo and conditioner! I have tried a lot and it just wasn’t feeling like it was properly cleaning my head and doing it’s job. My hair type is long, thin, and gets greasy fast. I also have a pretty bad hairline of that has any factors. I would like something that will clean my hair while leaving my scalp not dry and flaky. Also nothing over $100. Thanks in advance. Sorry i had to cross out my face and shirt

due to privacy concerns but here is an idea of what my hair looks like)

This is my hair line (i am only 16)
