Hesitant to buy bleach on eBay but too lazy and busy to go to the cosmetology store (closest one like 45 minutes away). I have tried wella, guy tang, and almost everything on the shelves at cosmoprof and NOTHING LIGHTENED MY HAIR LIKE THIS DID. new favorite bleach. Will be buying lots more!!! Thank you!!!
