I had brown hair and I got this dye that was made to dye blonde hair brown. I dyed it the first time I I didn't Like it so I dyed it again and I'm still not happy. I want to just dye it back brown but I don't want my hair to fall out. Do you think it will be okay if I deep condition and moisturize? I don't plan on putting heat on my hair for the next couple weeks so I thought it would be okay but I want to make sure!

Yeah of course it will be okay, along as you don't do it all in the same day. There's people that bleach their hair 5 times without much damage, so a box dye will do barely any damage, especially if its brown
