Bleaching gone bad... Did it?

Okay well I have clip in extensions. And I used Beyond the Zone bleaching formula 40 to bleach them. They were already stripped with bleach, and the rest was dark blonde. And well, I followed all the instructions and laid them out on newspaper, put the stuff on them, and then rinsed and washed with warm water. But they still look exactly the same. What did I do wrong?

You might not have left the bleach on long enough. If you have extensions, you want to be sure that they match the hair color you already have, so you might want to go to a professional hair salon for help.
Reply:If your extensions are synthetic hair you will not be able to change their colour. You can only change the ones that are 100% human hair.
