Just mix bleach powder with some shampoo (some people use bleach powder with the developer and then shampoo, but it's up to you) and wash your hair with the mix. Leave it on for a few minutes, and the color will disappear like Houdini.
Opposite colors, or complementary colors, have the power to cancel each other out. This principle is the cornerstone of effective color correction in hair coloring.
For natural colors, red fades the fastest. It's some science-y stuff about the size of the color molecules, but red is very hard to keep. Black is the most stubborn and hard to get rid of, even if you use a demi/semi dye.
Water exposure, sun exposure, hard water and pollution all contribute to color fading. And sulfate shampoo, besides being terrible for planet, will fade color too as will warm and especially hot water. All of these factors contribute to fading no matter what the color formula may be. And it also depends on the shade.
Baking Soda Paste
Baking soda can be an effective way to remove permanent hair dye naturally because of its lightening properties. Try mixing baking soda with lemon juice, which is acidic, to create a paste. Then, work the paste through your hair, allow it to sit for five minutes, and rinse thoroughly.
There are some sulfates included in shampoos that can be quite strong and inadvertently cause your color to fade. They do this by penetrating the hair's cuticle, which strips natural oils and dries out your hair.
Generally, reds, blues, and yellows are more susceptible to fading, with red pigments often being the most vulnerable. This is because these colors absorb more light, leading to quicker breakdown and fading.
The length of time that permanent hair dye will last depends on a few different factors, including the health of your hair, how often you wash it, what shampoo you use, and the type of hair dye you use. Generally speaking, though, you can expect permanent hair dye to last anywhere from 6 to 12 weeks.
It could be that your hair is resistant to tint, especially when the hair texture has changed as a result of going white. But also it could be that by going lighter, either all over, or by introducing (subtle) highlights you would not see the regrowth strip quite as quickly as if it were lighter.
Use a clarifying shampoo
If you need to remove hair dye fast, reach for a clarifying or anti-dandruff shampoo. These are like a deep cleanse for your hair. The harsh chemicals in these shampoos will strip your hair of color. They work by stripping away not just dirt and oil, but also any unwanted hair dye.
Dish Soap and Shampoo
Take about 5 drops of dish soap and add it to a quarter-sized amount of your shampoo. Use this concoction for 2-3 days to slowly remove the hair dye and see some results. Consider these methods if you are trying to wash out hair dye at home!
You can try washing with Dawn dish soap. It may remove some of the new dye If done quick enough. If you can't afford to go to a salon or there are none open for you to go to, you can try using a toner that will help tone down the new hair dye color.
Sulphate-rich shampoos are ideal for stripping hair since they help to release the colour - especially with dark or vibrant colours. These include clarifying or deep cleansing shampoo or anti-dandruff shampoo.
“A big trick is always using hot water when you shower, because it's opening up the cuticle and getting that dye to fade quicker,” she says. “Most brands and professionals will recommend cold water to keep the color vibrant, but for fading definitely use warm [or] hot water.”
Using a Clarifying Shampoo to Remove Hair Dye
Dieda says if your hair was dyed with permanent dye or you're in a rush to get the color out faster, try using a safe color stripper like Malibu C Professional's CPR (color pigment remover).
That's right: One of the biggest reasons for faded hair color is hard water. The same hard minerals that cause limescale around your home can also strip away hair dye. The more you wash your hair with hard water, the worse the problem will get.
Another thing to consider when choosing a shade is that warm colors (pink, red, orange, yellow) fade better and quicker, while cool colors (blue, green, violet) will stick around longer. While it's natural to feel apprehension, don't be afraid.
Fantasy Colors (Think Unicorn-Inspired): These audacious and vibrant shades, like neon pinks, blues, and purples, often exhibit the fastest fade. Their pigments come in larger molecules that wrestle with the task of penetrating the hair shaft, rendering them more susceptible to swift erosion.
As a general rule of thumb, darker colors tend to stay on the hair for longer. So, if you're adding lowlights, a root shadow or all-over depth, the shade will offer more mileage than, for example, light blondes, light browns or light reds. The same goes for pastel colors versus rainbow colors.
Avoid shampoos that contain sodium lauryl sulfate, sodium laureth sulfate, and sodium chloride. Sulfate in shampoo can cause hair color to fade.
The best way to banish unwanted lingering pigment is to wash, wash, wash! Use a nourishing cleanser like Beer Shampoo for this. Pigment will be washed away with every shampoo so the more you do this, the quicker the colour will fade.
Purple and blue shampoos help neutralize brassy tones in your hair, helping to lighten dyed hair and create a more desired shade.
