Did foil highlights on myself with this – turned out awesome! Let the packets sit until I saw they were light enough and then rinsed thoroughly. That way it doesn’t turn orange/yellow because the bleach gets enough time to work. And it definitely should, since this bleach has 6 percent hydrogen peroxide. It’s not mentioned here in the description, I did some research before buying (and it’s on the bottle when you get it home). Totally satisfied. I don’t get this blonde at the hairdresser at all.
