Bests & Worsts Reviews from Amazon

My daughter wanted to dye her hair a fun, bright color she found at Sally Beauty Supply. She purchased the only box of this bleach they had on the shelf so I purchased two more boxes of this bleach from Amazon to make sure we had enough for her thick hair. I applied the two Amazon boxes on the length of her hair and after nearly an hour with no noticeable lightening we were forced to apply the box from Sally Beauty to the roots so we could rinse her hair out ASAP to avoid damaging it. In under 15 minutes her roots were bright white (which is how this product is SUPPOSED to work). After rinsing completely we were left with an absolute MESS of pale roots and varying degrees of browns everywhere else on her head. I planned to share images of the results but my daughter is too devastated to sit for pictures. I called Sally Beauty to ask what could have caused such a thing to happen and she said the boxes we ordered were either very old or were kept in extreme temperatures. I am beyond angry and feel obligated to warn others NOT to order this product online because there’s no way to know if you’ll end up with the same mess.
