Review on Purple Hair Mask - Keratin & Jojoba Oil for Blonde, Platinum & Silver Hair - Eliminate Brassiness & Yellows Instantly - Made in USA - Hair Toner for Bleached & Highlighted Hair - Sulfate Free - 8 oz by Amy Smith

We used this on long hair that was mostly previously bleached and with a 3 inch recently bleached root that was lemon yellow. We hoped to remove the yellowing in freshly stained areas. , but the effect was minimal. It still looked yellow, just a little less. We've tried several similar products and gotten similar results, so I'm guessing we're just dealing with hair that's difficult to color. We ended up with a semi-permanent coloring darker shade. However, this product had a good conditioning effect.
