Color correcting bleached hair typically involves neutralizing unwanted tones and, for hair that is too light, reintroducing pigment to achieve a desired, often darker, shade. This process focuses on balancing the underlying pigments that become exposed or stripped during the bleaching process.
Bleached hair can often end up with unwanted undertones like yellow, orange, or even green if not properly toned or if a previous color fades incorrectly. The goal of color correction is to neutralize these tones using the color wheel and to restore the hair's integrity and desired color.
Understanding the Color Wheel for Correction
The fundamental principle of color correction relies on the color wheel. To neutralize an unwanted shade, you use its opposing color:
- Yellow is neutralized by Violet/Purple
- Orange is neutralized by Blue
- Red is neutralized by Green
- Green (often from chlorine or ash tones on blonde) can be neutralized by Red/Warmth
Common Bleached Hair Color Correction Scenarios
Here's how to tackle common issues with bleached hair:
1. Neutralizing Unwanted Tones
This is the most frequent need for color correction after bleaching.
-
For Brassy Yellow Tones:
- Solution: Use purple-pigmented products.
- Products: Purple shampoos, conditioners, or toning masks are excellent for regular maintenance. For more intense correction, a stylist might apply a violet toner.
- Example: If your blonde looks too yellow, washing with a purple shampoo a few times a week can significantly reduce brassiness.
-
For Orange or Coppery Tones:
- Solution: Use blue-pigmented products.
- Products: Blue shampoos and conditioners are designed to neutralize orange. Professional blue toners are also used for more stubborn cases.
- Example: For clients with lightened brown hair that pulls orange, a blue toning treatment can create a cooler, more natural brown.
-
For Greenish Tones:
- Solution: Introduce red/warmth.
- Causes: Green can appear if a cool toner is applied to overly porous, yellow hair, or from environmental factors like chlorine.
- Products: A very diluted red or warm-gold pigment can counteract green. This is a delicate process best left to a professional to avoid turning hair pink or orange.
2. Correcting Overly Light or Patchy Bleached Hair
When bleached hair is too light, uneven, or has lost its natural depth, the most effective and often least damaging solution is to dye it darker. This approach restores pigment and can give the hair a more natural, healthy appearance.
The "Filling" Process for Darkening
A crucial step for a successful darker color correction, especially after significant bleaching, is a process called "filling." Bleached hair lacks the underlying warm pigments (red and orange) that natural hair possesses. If you apply a darker, cool-toned dye directly to bleached hair, the result can often be flat, muddy, or even greenish.
- What it is: Filling involves applying a warm-toned color (like a diluted red, orange, or gold shade) to the hair before applying the final desired darker color. This reintroduces the essential underlying pigments that were stripped away by the bleach.
- Why it's important:
- It gives the hair warmth and depth, preventing the final color from looking dull or hollow.
- It ensures the new darker shade adheres properly and doesn't grab a cool, ashy, or muddy tone.
- It provides a stable base for the final color, promoting longevity and vibrancy.
A good stylist will always consider filling your hair to insert pigment back into your strands and give them warmth, which prevents your end color from appearing flat and muddy when going darker.
3. Correcting Damaged or Porous Hair
Bleached hair is often more porous and delicate. Color correcting it requires a gentle approach.
- Protein Treatments: These can help rebuild the hair's structure before coloring, allowing for more even color absorption.
- Bonding Treatments: Products like Olaplex or K18 can be incorporated during or after the correction process to strengthen bonds within the hair.
- Low-Developer Formulas: Using lower volume developers with toners or dyes minimizes further damage.
Professional vs. DIY Color Correction
While purple shampoos and conditioners are safe for at-home use, complex color correction, especially for significant tone shifts, patchiness, or going darker, is best performed by a professional colorist.
A stylist has the expertise to:
- Accurately assess your hair's condition and porosity.
- Formulate custom color mixtures using professional-grade toners, fillers, and dyes.
- Execute the multi-step process (e.g., filling, toning, dyeing) correctly to avoid further damage or undesirable results.
- Provide advice on aftercare to maintain your new color.
Attempting complex corrections at home can lead to unpredictable results, further damage, or an uneven, splotchy color that then requires more extensive professional correction.
Maintaining Your Corrected Color
Once your bleached hair is color-corrected, proper aftercare is essential to maintain the new shade and hair health:
- Use Color-Safe Products: Shampoos and conditioners specifically formulated for color-treated hair help preserve pigment.
- Limit Washing: Wash your hair less frequently to extend the life of your color.
- Cool Water Rinses: Hot water can strip color; cooler water helps seal the cuticle.
- Heat Protection: Always use a heat protectant spray when styling with hot tools.
- UV Protection: Sun exposure can fade color; consider UV protectant sprays or hats.
- Regular Toning: Continue using purple or blue toning products as needed to prevent unwanted brassiness from returning.
By understanding the principles of color theory and, most importantly, by relying on professional expertise for complex corrections, you can successfully transform your bleached hair into a beautiful, desired shade.
