best way to use wash-in bleach for your hair (results may varry depending on color of hair)

One way to fix a toner or hair coloring gone wrong is by giving your hair a bleach wash. Sometimes referred to as 'soap capping' or 'bleach bathing', bleach washing is a gentler way to remove color from your hair. Here's how to do it.

Pour shampoo into a mixing bowl. However much shampoo you normally use on your hair is how much you want to pour in the bowl.

• Remember, any shampoo is fine so long as it's not a toning shampoo.

Mix 1oz of bleach and 1oz developer into the second bowl. There are many different types of bleach - creme, oil, liquid, or power- but it really doesn't matter what kind you use. They all do the same thing in the end.

Pour everything into one bowl and mix together thoroughly. The shampoo - if a clear clarifying one - should turn a sky blue color after mixing together with the bleach.

• Add conditioner. This step is optional, but recommended to keep hair healthy.

Wet your hair with regular water. It helps to let it run under the shower for a bit and then give it a quick towel rub so it's wet but not dripping.

Apply bleach wash to semi wet hair. Starting at the ends, apply the mixture, work your way up your hair then give the whole lot a good rub, like shampooing your hair. Spray on some water to get it bubbling.

• It's okay to apply the mix only to spots where the hair didn't color quite right. If it's all over, though, feel free apply the solution all over.

Leave the bleach wash in for 10-15 minutes. You can put on a shower cap in order make sure your hair doesn't touch clothes or clothing. Scrape off a bit of bleach every few minutes to keep an eye on how much it's lightening.

• For already bleached hair, you may only need 7 - 10 minutes.
• For removing a dark dye, you may want to process it longer than 10-15 minutes, though it should only be 30 minutes maximum.
• If you do decide to use 30 or 40 vol - for extra lift or speed - don't let it process longer than 7-10mins (depending on your hair color and condition).
• Be careful to keep a close watch on your hair's progress throughout!

Wash out the solution. While doing so, use a deep conditioner. Wash your hair out as thoroughly as you can.

• If you're trying to remove hair dye, your hair should look orange or yellowish.
• If you're trying to remove a toner, it should leave the hair yellow.
