I applied the brightener to dark brown hair. The brightener has not burnt on my scalp, at most a little tingled. Unfortunately I had a light red tone in the hair. At the edges where the red tone reside, my hair became bright orange, but at the beginnings it became very blond, even brighter than on the product picture. The one with the orange was not bad, because I wanted to go anyway with dark red color over it.
Conclusion: I would definitely recommend the brightener, if you want to lighten your natural hair color.
