I need an answer from someone that knows alot about hair coloring!

I am on the fence about going back to the hair salon to get my hair colored again.

What I am curious about is if I use hair color products that you can use at home, will my hair turn green or a funky colour? Will the salon hair color treatment affect the home color treatment (if the two are combined)?

I had my hair colored twice in the last week and a half (both at a salon). So, now that some time has passed and I have washed my hair regularly since...is it SAFE to try home coloring products? If yes, what brands would you recommend?

I am so worried that if I try to color my hair at home that my hair will either fall out or become a strange color to the point I'll have to wear a hat and go back to the salon.
