Different bleaches?

Right, so I posted a thread on here ages ago about dying my hair Blonde. I was worried it would go orangy yellow as it had done before because Im a natural dark brunette. But when 3 of my friends who are naturally strawberry blonde went to the same hair salon, each of there's went a yellowy orange colour Blonde. So is it the bleach that my salon uses thats making my hair go gingery or what?
Thanks.

If the salon made your friends hair go strawberry blonde, then they might not be as good at coloring as another salon. Try getting a recommendation from another friend or person in your area that's had a successful bleaching before using them. As I understand it, colorists are people, and can mess up sometimes..perhaps the colorist at that salon isn't as good as one you can find elsewhere.

Good luck
