Hair growth

I had a hair cut today and the stylist did not do what I wanted. I walked in with my hair almost touching my butt, I asked for a trim and for my dead ends to be gone. She cut off 8 inches of my hair and I am absolutely devastated. Does anyone have any recommendations for shampoo, conditioners, hair masks, supplements, anything that will help my hair grow.

The last time my hair was short was 8 years ago and it took me this long to get to the length it was. My hair grows extremely slow.
