I dyed my hair with arctic fox hair dye a few weeks ago, will my hair be okay if i put henna hair dye on my hair?

I bought henna hair dye from the company Almas Henna on amazon a few days ago. I probably should’ve done more research into the company but I wasn’t thinking and just ordered it. I’ve been dying my hair different colors for the last eight months and I’m tired of maintaining it. I just want to dye it jet black while damaging it as less as possible. Is my hair going to melt off if I put it on my hair?
