A semi- or demi-permanent hair color with green or ash undertones can effectively neutralize red tones in hair. The color level should be as dark or slightly darker than the existing red to properly counteract it.
Understanding Color Correction
The principle behind "killing" red hair involves color theory. Red and green are opposite each other on the color wheel, making them complementary colors. When applied to hair, green-toned dyes cancel out the red, resulting in a more neutral or brown shade. Ash tones also help neutralize warmth and red.
How to Neutralize Red Hair
Here's a breakdown of the steps to neutralize red hair:
-
Assess the Level and Undertone of Your Current Red Hair: Determine how dark or light your red hair is and the specific shade of red (e.g., copper, auburn, strawberry blonde). This helps you select the appropriate color level of your neutralizing dye.
-
Choose the Right Hair Color: Select a semi- or demi-permanent hair color with green or ash undertones. The color level should be the same as or slightly darker than your current red. Consider these points:
- Semi-permanent Color: Washes out gradually over time (typically 6-8 washes). Good for temporary color correction or testing a new tone.
- Demi-permanent Color: Lasts longer than semi-permanent but still fades gradually (around 24-28 washes). Blends well and minimizes harsh lines as hair grows.
- Green-Toned Dye: Best for extremely vibrant or intense red tones.
- Ash-Toned Dye: Great for softer, more subtle red or copper tones.
-
Strand Test: Perform a strand test on a small, inconspicuous section of your hair to see how the neutralizing color interacts with your hair. This step is crucial to prevent unwanted results.
-
Application: Carefully apply the chosen color according to the manufacturer's instructions. Make sure to evenly coat all the red areas you want to neutralize.
-
Rinse and Condition: Thoroughly rinse the dye from your hair until the water runs clear. Apply a color-safe conditioner to help lock in moisture and maintain the new color.
Examples
- If you have a light, strawberry blonde with red undertones, you can use a light ash blonde demi-permanent color.
- For a dark, auburn red, consider a medium ash brown or green-based brown demi-permanent color.
Important Considerations
- Hair Porosity: Porous hair absorbs color more quickly, potentially leading to an uneven result. Make sure to do a strand test.
- Hair History: Chemically treated hair might react differently to color. A consultation with a professional is always a good idea.
- Professional Help: If you're unsure about the process or dealing with significant color correction, consult a professional hair colorist.
