By looking at color theory and choosing the opposite color of your hair in the color wheel, such as purple or blue shades, you can neutralize the yellow and orange.
PURPLE/VIOLET PRODUCTS
Purple is the exact opposite colour to yellow on the colour wheel, so when mixed together they essentially cancel eachother out.
If you're seeing yellow more than you' are seeing Orange, use a violet-based shampoo. Violet is light purple and purple neutralizes yellow. These types of shampoos have direct dyes in them that stain over the top of the hair. The more often you use them the more direct dye is overlaid on the hair shaft.
Blue! Purple cancels out yellow, blue cancels out orange!
During the lifting process, a mixture of ammonia and bleach, along with peroxide, is applied to the hair and allowed to process until the existing color is either diluted or removed. Then tones are added back into the now bleached hair in order to give it the desired color.
For warmer undertones (think hints of yellow or orange), your ideal hair color should give your skin a healthy, natural-looking flush. Go for hair colors that are cool, ashy, or have reddish tones, like honey or strawberry blonde hair, golden copper, cool beige brunette, and rich golden brown.
I would try a purple/blue shampoo first. Use it a few times a week for a couple weeks. It won't fix it overnight, but you should notice a nice gradual change without damaging your hair more. If that doesn't work, a toner would be your next least damaging option.
Recommended Colors for Neutralization
For unwanted yellow tones, purple-hued products are recommended. Orange or brassy tones are best neutralized with blue, while red tones find their match in green.
One option is to re-bleach the roots to lift them to a lighter level before toning again. You need to get them to that very pale yellow - think the inside of a banana. This will help to ensure that your favourite toner can effectively neutralize any remaining yellow tones and match the rest of your hair perfectly.
Yellow hair is also known as blonde hair..
chemical oxidation from synthetic ingredients is one way hair turns yellow. The other is “staining”, and that is where natural ingredients come into play in a big way. According to Dr. Joe, “natural” ingredients, which most of us assume to be safe and gentle in every regard, can really do a number on your hair color.
As a 2nd step, I use L'Oreal Excellance - 9A shade - light Ash Blonde to achieve platinum hair color. Ash cancels the yellow. But make sure to only apply the ash product on the hair that you bleached that are yellow. The ends of your hair are usually much light and will absorb the ash color much quicker than the roots.
Purple shampoo adds tiny deposits of color to your hair to counteract yellow and orange shades. If you use it once a week in place of your normal shampoo, it may keep the yellow out of your hair. Choose a darker purple if you have blond hair or a light violet for silver or white hair.
The best toner for orange brassy hair will be one that is very cool toned (think ashy) and one that has a blue base to it. When I say a blue base think of that as like the main pigment in the colour so you want to find a toner that has a lot of blue pigments to it.
By looking at color theory and choosing the opposite color of your hair in the color wheel, such as purple or blue shades, you can neutralize the yellow and orange. This method gives the impression of cooler tones without affecting the pigments in a permanent way.
When deciding how to tone yellow hair to ash, try using a violet shampoo first. As purple is the opposite of yellow on the colour spectrum, the shampoo's purple pigment draws out the yellow brassiness from your blonde, neutralises those unwanted tones, and makes your colour look cooler, healthier and more vibrant.
In the salon, your stylist can apply a low-ammonia toner formula to your hair after it is lightened. For example, if the goal is a pearly blonde shade, your stylist will use a lightener first, then apply a violet toner to cancel out the yellow tones that are exposed when your hair color is lifted.
Demipermanent hair color is a versatile option that can effectively neutralize yellow or unwanted tones. It contains a low level of peroxide, which helps to open the** hair cuticle** and deposit color molecules into the hair shaft.
