Yellow and orange hair

I wanted it white can the pro do it asap or do I have to wait???

you might want to wait a little while so your jair doesn't fry

I meant hair, obviously. I hate when I make typo's.

well you should probably wait, cause it will definately fry.
but while your watiing you shouild you either a toning shampoo or conditioner, it will take out the orangy tones and make it more blonde, I have white hair now. and that keeps it a good color.
I would suggest using a shampoo called shimer lights, and then a deep conditioning mask 3 times a week.
this will keep it healthy and take out some of the orange. then in a bout a week I would go to a pro and have them bleach it. and continue to use that shampoo and conditioner that I mentioned.
:]
hope this helps
