I got a sample of John Frieda Go Blonder Lightening Spray with a recent ULTA order, and thought I'd give it a quick google before trying it. Check out these scary ass reviews on Makeup Alley. Holy shit! I think I'll put this one directly in the garbage.
(On other sites there are some good reviews alongside the terrible ones, but that's enough to warn me off. Even a small chance that my hair will shrivel up and fall out is enough.)
