Ok so I've been dying my hair every 2-4 months for the past two years and I've heard that if you keep dying your hair it will fall out. But my goal is to get back to my natural hair color by dying it because my hair grows extremely slow. I was wondering id it would be safe to strip it and dye ash brown over my black hair?

Stop playing around with your hair and dyeing it at home. Go to a professional hair salon to have this done correctly before all your hair falls out.

dying = near death
dyeing = changing hair color
