Tips to prevent oily hair or to decrease hair oil at the roots?

What are some good products that can decrease hair oil or prevent oily hair? I don't want it to clog my scalp pores and cause hair loss or thinning cause of it. I believe it played a factor in my change in texture over the years plus genetics. Is there a way to unclog those follicle pores so that hair can grow out better and thicker again? Any good shampoos or any lifestyle changes I can make to decrease the amount of oil production in my scalp?
