The color that counters and neutralizes unwanted yellow tones in hair is purple (violet). This is based on the color theory principle that colors opposite each other on the color wheel cancel each other out.
Leaning into the color wheel, blue cancels out orange tones, and purple (or violet) cancels out yellow tones. I've incorporated both products into my hair maintenance routine.
Red tones work great over yellow or darker hair in my experience. I also had pink hair that wasn't bleached very light, it faded to a coral color, so that would probably be a good bet as well. Just keep in mind that pastels need very light hair to work, so darker color is better.
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.
The hardest hair colors to remove are typically black and vivid reds, due to their dense pigment load and strong staining power, often requiring multiple bleaching sessions; while vivid blues and purples are also very difficult, especially cool-toned ones, because their small dye molecules deeply bond to porous hair, making them stubborn to lift.
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.
Your hairdresser likely advised against purple shampoo to prevent dryness, dulling, uneven color (ashy/muddy), or over-toning (purple/blue tint), as it's a temporary fix not for everyday cleaning, and can interfere with future coloring by creating buildup, especially if your hair is very porous or already a bright, cool blonde. They might prefer professional toners, moisturizing treatments, or detox shampoos for better, healthier results.
4. Let it sit in your hair
There's no single "ugliest" hair color, as beauty is subjective, but natural red hair is often cited as least popular in attractiveness studies due to rarity and stereotypes, while some find unnaturally dyed colors (like harsh yellow blonde from bleaching, flat coal black, or certain aggressive fashion shades) less appealing, or simply, a color that clashes with a person's skin tone.
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.
Dish Soap
Fortunately, if you go through the effort of using this drying soap on your dyed hair, it can help remove unwanted color. You'll need to do many washes to fade it out, but it is a step in the right direction if you want to remove a color. Some people throw baking soda into their dish soap for an extra boost.
The hardest colors to maintain are typically reds as a fade out the fastest. I recommend color refresh in between appointments to keep the color vibrant. Also, trying to maintain a blue black color is very difficult as a blue tone tends to leave hair the fastest as it's the biggest molecule.
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.
Purple is yellow's opposite on the color wheel, which means it neutralizes those brassy tones like magic. Choose the right purple product based on your specific yellow situation: Periwinkle: Our pastel blue with purple undertone hair dye is perfect for darker yellow tones that lean orange.
Odds are your hair wasn't lightened enough when you had it professionally done. You need a toner applied and processed for at least 15-20 minutes. Keep using the purple shampoo and leave it on longer than you have before. Make sure you condition well afterwards as these toning shampoos can dry out your hair.
What are the worst shampoos for hair loss?
Brassy tones in dyed or bleached hair can fade over time, but they often persist as the underlying warm natural pigments re-emerge with the fading of the dye or toning treatments.
How to get rid of yellow and orange tones in your hair
Toners help you achieve the initial colour, while purple shampoo helps you maintain it. In the battle of toners vs. purple shampoo, there's no one-size-fits-all answer. The choice depends on your hair goals, maintenance routine, and personal preferences.
A bleach bath typically lifts hair 1 to 3 levels, offering a gentler lift than traditional bleaching by diluting bleach with shampoo and applying it to wet hair, making it great for removing toner, correcting color, or subtle lightening, though results vary based on your starting hair color, porosity, and developer strength.
There's no single "ugliest" hair color, as beauty is subjective, but natural red hair is often cited as least popular in attractiveness studies due to rarity and stereotypes, while some find unnaturally dyed colors (like harsh yellow blonde from bleaching, flat coal black, or certain aggressive fashion shades) less appealing, or simply, a color that clashes with a person's skin tone.
In relation to food: Blue is actually known to suppress appetite and reduces hunger. Simply put: the most unappetizing colour.
The "Big 3" hair loss treatments, popular in forums, are Minoxidil, Finasteride, and Ketoconazole shampoo, often combined to tackle hereditary hair loss (androgenetic alopecia) by boosting growth, blocking hormones, and reducing inflammation. Minoxidil (Rogaine) widens blood vessels, Finasteride (Propecia) blocks DHT, and Ketoconazole fights scalp fungus and inflammation, with microneedling sometimes considered a fourth addition.
