MY HAIR IS STILL ORANGE!! HELP!!

If you are doing this yourself, you will have to dye it more than once before you get white blonde. Are you using a 30 or 40 volume developer? Use a highlift (level 10) dye with a blue base right now, and once all of your hair is yellow, switch to a highlift (level 10) dye with a violet base. This will more quickly counter the yellow to get it white. If you're using Clairol, there are instructions on how to get higher lift quicker on the bottle (I believe you increase the amount of developer in the proportion suggested). Leave the dye on for a maximum of 45 minutes (after 45 minutes, it's lost a lot of it's processing power, and it's better to start again with fresh stuff).

First of all, if you can afford it, your best option is to go to a knowledgeable professional colourist.

If that's not an option, here's my advice. Keep in mind that I'm an amateur. I'm just drawing on my own personal experience and research --

Sometimes it can take three bleach applications to get to pale yellow. I wouldn't recommend bleaching to white, though. When hair is bleached to white it's very close to breaking. You can get a very pale "white" blonde by bleaching to pale yellow and using a platinum or ivory toner. 40 vol. developer won't get your hair any lighter than 30 vol. when it comes to lightening your hair with bleach. When you're bleaching, the lightening power comes from the bleach not the developer. Upping the peroxide may speed up the bleaching process a bit, but bleaching slowly is less damaging to your hair. (40 vol. can also be really irritating to your scalp. It's usually necessary for a high-lift tint, but if you're bleaching, the peroxide isn't serving as the lightening agent.) If your hair still looks and feels healthy, you could probably do one more application of bleach to get to pale yellow. You may have to do a bit of spot bleaching to get an even tone since you have some darker areas. Applying the bleach to those areas first may help even out your tone. Getting a friend to help you is a good idea.

If your hair looks and feels damaged, though, you may want to tone your hair at its current level with a medium ash blonde demi-permanent. Level 7 healthy hair looks a lot better than fried level 10 hair.

Something else that may help if you decide to bleach one more time -- Bleach is only active as long as it is moist. Some bleaches can continue lightening your hair for up to 90 minutes, but not if they dry out first. Misting dry spots with a bit of water and wrapping a plastic bag around your hair while the bleach is processing can help improve its efficacy.

You might find this link informative. It explains how the bleaching process works and what it actually does to your hair.: http://scott.k12.va.us/scctc/Cosmetology/hairandcolor.htm

Best of luck

P.S. It's a good idea to do a test strand before bleaching again to make sure your hair can handle it. Apply the bleach to a 1/2" wide section of hair. Wrap it in tinfoil and let it process until it reaches your desired level -- or for 90 minutes (whichever comes first). Then wait 3 days and check that area for breakage. (It can take up to 3 days after processing for the full extent of damage to appear.) If it feels fragile or spongey when it's wet or it snaps, you'll know that your hair would be destroyed by one more bleach application. It's just not worth the risk.
