If you want to tone down the brassy-yellow tone of your hair, you can choose to apply a purple toner, bleach it to lose pigment, or apply a darker dye. If you want to tone down a blonde, almost white hair, what you have to do is apply a darker dye or a gray toner.

Try baking soda. Mix equal parts baking soda and shampoo. Wash your hair with this mixture each day until the color fades. Usually, a one-to-one mixture works fine. However, if you have very thick hair, try adding slightly more baking soda than shampoo.

Fade Your Dye With Shampoo Tish and Snooky say that the easiest way to fade too-bright hair color is with shampoo, particularly a clarifying shampoo (or something equally strong). If you go that route, both Demelo and Aronson suggest lathering up with a sulfate-free shampoo.

A toner can be used when lightening hair to tone down brassiness or orange tones, or a toner can be used to slightly darken and deepen too-blonde hair color. If you’ve dyed your hair and it’s way too blonde, mix a toner that’s one shade darker than your current color.

It’s definitely doable, and gentler than dyeing it. But there are a few things to keep in mind, otherwise you might end up with a green or orange hue – and that’s probably not what you want. Generally speaking, the darker you want to tint your blond hair, the more delicately you need to tread.

To tone down bleached hair that’s too light, you should use a dye that’s two colors darker than your current shade. And you should always do so at least three days after you bleached it.

Toner can be applied in-salon, where a professional colorist can apply a toner tailored to your hair shade. But when you can’t make it to the salon, you can try at-home products that help tone blonde hair at home.

When it comes to how to apply purple shampoo on dry hair you want to thoroughly work the product into your dry strands. Then leave it on from between 5 to 30 minutes depending the health of your hair.

The short answer: No! People have been trying this technique because your hair will absorb more of the purple pigment when it’s dry.

Even though purple shampoo isn’t a dye, but a neutralizer to get rid of the yellow in your hair, if you let your hair be exposed to its formula for too long, the only thing that’s going to happen is the violet pigments of the shampoo will leave a horrible blue or green tint in her hair depending on your hair color.

What happens if you leave purple shampoo in your hair for an hour or more? Your hair will end up an intense and beautiful color like you’ve never seen before. Your hair will start to fall out until you are completely bald. Your hair will end up with horrible blues and purples leftover.

It becomes too much and can lead to an ashy tone if you over do it with both shampoo and conditioner. Purple shampoo followed by a good condtioner is more than enough. If, by chance, you ever over-do it and take it one purple shampoo too far, don’t worry.

While that is perfectly fine, there are times that the outcomes are just too extreme and irreversible. For blondes, especially with platinum hair, overusing purple shampoo can lead to severe staining. Obviously, shampooing the hair too much can also lead to more damage.

Some blondes swear by locking in the purple toning with a purple conditioner. However, as the purple shampoo does most of the work, we think it’s OK to use any conditioner you like. After rinsing, try a deep moisturizing hair mask to soften your hair, and smooth frizz.
