I used Schwarzkopf for my blonde with great results, but tried to switch to a Sally brand for the ease of local purchasing. Mistake! The so-called comparable Sally products left my hair with a neon-orange sheen and really dried my hair out, a lot. They also turned my scalp red for a day, which wasn't painful, but obviously very irritated. Switched back to Schwarzkopf, and not only am I icy-white, it was significantly more gentle on my hair and no irritation to my scalp .
