The chemistry behind the green tint: Why does it occur in the first place?
The dreaded green tint when dyeing hair black is a common problem that frustrates many home dyeers. But what is actually behind it? To understand this phenomenon, we need to take a look at the chemistry of hair dye.
The Role of Pigments
Black hair dye contains a mixture of different pigments, including blue, red and yellow tones. In the ideal combination, these produce a rich, deep black. But sometimes the delicate balance of these pigments can be disturbed.
If the red and yellow pigments fade faster than the blue, this can lead to an undesirable green tint. This happens especially often with pre-bleached or highly porous hair, as it loses the color pigments at different rates.
influence of pH value
Another important factor is the pH value. Hair dyes with a pH value that is too high can open the hair cuticle too much. This means that the color pigments penetrate more easily, but can also be washed out more quickly - often unevenly, which promotes a green tint.
External factors
External influences can also play a role:
- Hard, chlorinated water
- UV radiation
- Frequent washing with aggressive shampoos
- heat exposure from styling tools
These factors can attack the color pigments in the hair and lead to uneven fading, which increases the green tint.
If you understand the chemistry behind the green tint, you are already a big step closer to avoiding it. In the next section, we will show you how to optimally prepare your hair for coloring in order to create the best conditions for a long-lasting, deep black right from the start.
Preparation is everything: How to prepare your hair optimally
Thorough preparation is the key to a perfect coloring result without a green tint. With the right steps, you create the ideal basis for a radiant, long-lasting black.
perform hair analysis
Before you start coloring, it is important to know the condition of your hair. Check the following:
- Porosity: How quickly does your hair absorb moisture?
- Texture: Is your hair fine, medium or thick?
- History: Has it been dyed or chemically treated before?
These factors influence how your hair reacts to the color and help you choose the right color formula and exposure time.
perform deep cleaning
A thorough cleanse removes product buildup and opens the cuticle slightly to allow color to penetrate better. Use a clarifying shampoo to do this, but be careful not to overdo it—you don't want to completely strip the natural oils.
Conditioning hair
Well-conditioned hair absorbs color more evenly. Use a light conditioner that doesn't weigh your hair down. Focus on the lengths and ends, as these areas are often drier and more porous.
pH balance
To ensure optimal color absorption, it is helpful to slightly raise the pH value of your hair. You can achieve this with a mild baking soda and water solution. To do this, mix a teaspoon of baking soda with 500 ml of water and rinse your hair with it after cleansing.
take protective measures
Protect your skin from discoloration by applying a thin layer of Vaseline along your hairline and on your ears. Wear old clothes and prepare your bathroom with towels to avoid stains.
With this careful preparation, you create the perfect basis for an intense, even black without a green tint. In the next section, you will learn how to make the right color choice to minimize the risk of a green tint right from the start.
The right choice of color: Which shades prevent green tint
Choosing the right shade of black is crucial to avoid a green tint. Not all black is the same, and the subtle differences can make the difference between a brilliant result and a disappointing one.
Understanding Different Shades of Black
Black is not just black. There are different undertones that you should know:
- Blue-tinged black: Cool tones that often tend to have a green tint
- Violet-tinted black: Neutralizes yellow and green tones
- Warm black: With reddish undertones for more depth
Making the ideal choice
For a deep, shiny black without a green tint, experts often recommend violet or warm blacks. These shades help balance out unwanted green and yellow tones and give the hair a rich, multidimensional color.
use color additives
Some professional hair dyes offer the option of adding color additives. These can help minimize the risk of a green tint:
| color additive | Effect |
|---|---|
| Red | Neutralizes green tones |
| Violet | Prevents yellowing |
| Gold | Adds warmth and depth |
natural hair color
Your natural hair color plays an important role in choosing the right shade of black:
- For light or grey hair: Choose a warmer black with reddish undertones
- For medium to dark brown tones: A neutral to slightly violet-tinted black works well
- For already dark hair: A cool black can be suitable, but be careful with tones that are too blue
Get professional advice
If you are unsure about which shade is best for you, do not hesitate to consult a color expert. Professional colorists can analyze your hair structure and color and recommend the perfect shade of black that matches your skin tone while minimizing the risk of a green tint.
By choosing the right color, you have laid the foundation for a brilliant black. In the next section, you will learn how to apply the color professionally to achieve an even and long-lasting result.
Application tricks from the pros: Exact techniques for perfect black
The right application technique is crucial for an even, deep black without a green tint. With these professional tricks, you can achieve results like those from the hairdresser.
Sectioning for precise application
Divide your hair into four to six sections, starting at the back of your head and working your way forward. This method ensures that each section is dyed evenly and no spots are missed.
The right application technique
Apply the color in thin layers using a coloring brush. Start about one centimeter from the roots and work your way to the ends. Gently comb the color through to ensure even distribution.
Timing is everything
Pay close attention to the recommended exposure time. Do not exceed it, as this can lead to excessive pigment absorption and possible green tint. In general:
- Roots: Apply the color here last as they develop faster
- Lengths and ends: Often take a little longer, especially with porous hair
Check the temperature
Heat can speed up the color development. Wrap your hair in plastic wrap to maintain an even temperature, but avoid additional heat sources as these can lead to uneven results.
perfecting dishwashing technology
Rinsing out the paint is just as important as applying it:
- Rinse first with lukewarm water until it runs clear
- Then use a color-protecting conditioner
- Finally, rinse with cool water to close the cuticle
Professional color sealing
For a long-lasting result, experts recommend a color sealant:
| method | Effect |
|---|---|
| acid flushing | Closes the cuticle, fixes the color |
| oil treatment | Nourishes the hair, prevents dryness |
| protein treatment | Strengthens the hair structure, extends color durability |
Don't forget aftercare
Immediately after coloring, your hair is particularly receptive to care. Use this time for an intensive moisturizing mask or oil treatment to nourish and protect freshly colored hair.
With these professional application techniques, you lay the foundation for a long-lasting, deep black without a green tint. In the last section, you will learn how to care for your new hair color and maintain its shine for as long as possible.
