Its the same with using purple hair dye on green hair……. a little or light pigmented purple will make it more of a ugly blue green that might have a slight brown tone as any yellow in the green would go a dark blonde/light brown from the purple toning it……
Purple or Burgundy: Go Bold and Cover Green with Style
Purple or burgundy shades are great for both masking green and giving your hair depth.
Does purple toner on green hair work? No, purple toners do not correct green tones in the hair. To cancel green, you need a red toner or shampoo.
Red or Copper: Since green is opposite red on the color wheel, using a red or copper dye can help neutralize the green. A deep red or a vibrant copper can provide good coverage.
Purple is used because, if you take a look at the color wheel, it's the direct opposite color of yellow. Does purple cancel out yellow? The answer is yes. So when using purple pigment on brassy, yellow tones it color corrects your hair's hue, restoring it to its former brighter, cooler color.
On the color wheel purple and green only have blue between them. So depending on the color of purple you use would decide the results. But to give you a average result the hair should go blue.
Purple & Yellow
When examining a color wheel we see that purple is opposite to yellow, meaning purple can counteract yellow.
If you're trying to neutralize or tone out a shade, use the one directly opposite on the color wheel! In this case, pink and red tones will tone green. Pink Toning Conditioner is a red-leaning pink designed to take care of green and even teal tints!
A baking soda wash can be a first line of defense against green hues. Simply create a paste by mixing baking soda with water. Apply this mixture to wet hair, concentrating on the green-tinted areas. Let it sit for about 5-10 minutes but not longer as it can be drying.
Hack admits that red hair is his favorite to color, but that she's noticed many women don't realize the extent of after-care that's needed. “Red is the hardest color to keep lustrous and the hardest color to remove,” she adds.
But can you believe it: IT WORKED! I generously smeared and combed the ketchup into my ends, wound my hair into a bun, gave my girls their bath for 20 minutes or so, then shampooed/conditioned, and just like that, the green slime was gone. My blond streaks were back and intact.
Dyeing dark brown hair purple
We'll get the bad out of the way first; unlike our blonde and redhead sisters, chestnut shades are typically more stubborn to shift in colour. This means you'll have to lighten your hair a lot if a pastel lilac shade is your desired look.
Purple shampoo contains purple pigments, which help to neutralize the green tones and restore your hair's natural color. To use purple shampoo for this purpose, simply apply it to wet hair and concentrate on the areas with the most visible greenish tint. Allow it to sit for a few minutes before rinsing thoroughly.
If you bleached your hair blonde, chances are your purple hair dye will fade to an ashy silver with purple hues. For many people whose hair was slightly warmer, their hair faded into a purple-pink or purple-blue shade until the brown or dirty blonde underneath began to show through.
So what are the colours that compliment purple? Yellow, orange, and green are the most obvious ones. However, contrasting colours aren't the only ones that matter. Colours right beside each other on the wheel also complement each other.
The green should be neutralized with the color that is opposite it on the color wheel—red.
If green tones have already appeared in your hair, there are several color correction techniques you can try. One effective method is using a red-based color to neutralize the green. Applying a warm-toned dye can counteract the unwanted hue and restore your hair to a more natural shade.
Baking Soda Paste: Baking soda is a versatile ingredient that can help remove green tones from blonde hair. Mix 1/4 to 1/2 cup of baking soda with just enough water to form a paste. Apply this mixture to the affected areas, let it sit for 10 minutes, then rinse thoroughly.
Cool skin tones, such as those with a blue or pink undertones, look best with green hair colours that have blue undertones, such as emerald or turquoise. On the other hand, warm skin tones, with yellow or golden undertones, look best with green hair colours that have yellow undertones, such as lime or olive.
So, how to dye your blonde hair brown without it going green? You've got two options: Fill your hair: filling means nothing more than pre-dyeing your hair before putting on the brown hair color. Opt for copper red colors, such as Vesuvius Red, or golden shades.
If you leave purple shampoo in your hair for 30 minutes, the risk of over-toning increases significantly. While purple shampoo is designed to neutralize brassy or yellow tones, leaving it on for an extended period can lead to overly cool or even purple-tinted hair, especially for those with light or porous hair.
It's not your imagination — red hair dye does fade faster than other hair color shades.
