So, you decided that red was going to be your new hair color, but once your hair was dyed, it turned out a little too red! What can you do?
When it comes to fixing a red that is too red, there are a few things we need to do first. First, we need to ascertain what level the red is actually on.
Fixing Hair Color That’s Too Red
Hairdressing industry standards mean that all hair colors are measured on a scale of 1 to 10, with 1 being black and 10 being white blonde. Reds are no different. They generally range from a very pastel rose gold at level 10 to black with underlying red at level 1. But to fix the red, we need to work out what shade of red it actually is.
Level 6 Red
To explain it in simple terms, there are 3 ways to fix your overly red hair. The first, and probably the easiest, is to color over the red with another slightly darker ash or matte brown color to neutralize and eliminate many of the red tones.
A darker shade can hide the red at first, but it is usually a quick fix. After a week or two, the new color can fade. Then, the warm tones show again, and the hair can look clearly red.
The second choice is to neutralize some of the red tones with green or anti-red tones.
This is where you need to work out what your base color is because, if you decide to tone or neutralize some of the red, the new color will need to be at the same level or darker.
The anti-red or green tones, which are on the opposite side of the color wheel, will not work if the level you are toning with is lighter than the current color of the hair. For example, if your hair is a vibrant level 6, you need to use a level 6, 5, or below with either a green color corrector or an anti-red tone to help neutralize the red.
If you are trying to neutralize the rose tones in your very light, level 9 rose-gold hair, you need to use a level 9, 8, or below with a fraction of green or anti-red in it to neutralize the “rose or red tones” in the hair. If you use a level 8 green or anti-red formula on level 6 hair, it won’t do anything!
If you have looked at your red and it’s really too red, but you really do not want to go any darker, another option is a gentle bleach bath, also called a soap cap. Mix equal parts: 30 g of bleach powder, 30 g of low-volume developer, such as 5-volume or 1.5%, and 30 g of mild sulfate-free shampoo. Because bleach reacts unpredictably on color-treated hair, this step is safest when done by a licensed colorist, especially if your hair has been previously colored, lightened, or relaxed.
⚠️ Safety Warning: Never apply a bleach bath directly to the scalp. Keep the mixture at least half an inch away from the root area to prevent contact dermatitis or chemical burns. Do not attempt this process if your hair is already brittle, highly porous, or previously chemically relaxed, as it will cause irreversible structural breakage. Always perform a strand test first.
Keep in mind that a bleach bath is only a transitional step. It will effectively strip the red, but it will leave behind a raw, brassy orange or yellow-orange canvas. You must follow up by applying a demi-permanent color or toner to neutralize those warm underlying pigments and achieve your final desired shade.
Level 5 Red
You then have the opportunity to apply a new color at the desired level, taking into account the underlying reflect and pigment that will come back through the red.
The other option is to add some anti-red or green to the new color mix to balance out the red overload in the new color.
Pro tip: Whenever you have to perform a ‘color correction‘ like any of these options, first, it takes a couple of days to ‘settle in,’ and second, it usually takes 2–3 coloring sessions after a color correction for the color to be perfect again!
Third and most importantly, if you have used box colors to try to achieve your perfect color, I apologize in advance, but your color will rarely be the desired outcome.
Box colors use a one-size-fits-all formula, so the same ammonia and peroxide levels are applied to everyone’s hair. A custom salon formula can be adjusted to your hair, which may make it gentler on the mid-lengths and ends.
For example, most colors use 20-volume peroxide or 6% to cover gray. For the mid-lengths and ends, we actually only need a semi-activator or 1.5%. When 6% is pulled through rather than the correct formula of only 1.5%, it causes cumulative damage, excessive dryness, and porosity over time. It can leave a dull, matte look to the hair, and it does not feel nice at all!
When the correct salon color is used, it can leave the hair healthy and shiny. Well-hydrated hair, due to the silk proteins and nutrients in the semi-permanent colors, also feels like it has substance and helps prevent breakage, allowing you to retain your length!
So, now that we have the red we love, it’s super important to be kind to your tresses. This means using a salon-quality shampoo, conditioner, and mask once a week. It also means protecting your gorgeous locks from the sun and chlorine if you are a swimmer!
Red dye molecules are larger than most other dye molecules. Because of this, they do not sink deep into the hair cortex. They stay closer to the cuticle surface. That is why red can fade quickly, especially if the cuticle stays open. Common causes include too little conditioning, dry hair, and frequent heat styling. Now you have the ultimate red—GO AND ROCK IT!
