Mixing hair dyes to cover highlights is a common question for those looking to achieve a uniform hair color. Yes, you can mix hair dyes to cover highlights, but it requires careful consideration of color theory and hair condition. Understanding how different shades interact is crucial to avoid unexpected results.

How to Mix Hair Dyes to Cover Highlights

When blending hair dyes to cover highlights, it’s essential to choose the right shades and follow a strategic approach. Here’s a step-by-step guide to help you achieve the best results.

Step 1: Assess Your Current Hair Color

Before mixing dyes, evaluate your current hair color:

  • Base Color: Determine the dominant color of your hair.
  • Highlight Shade: Identify the tone of your highlights (e.g., blonde, caramel, or red).

Step 2: Choose the Right Hair Dyes

Selecting the appropriate dyes is crucial. Here are some tips:

  • Complementary Shades: Choose a dye that complements both your base color and highlights. For example, if you have blonde highlights on brown hair, a medium brown dye can help blend the colors.
  • Permanent vs. Semi-Permanent: Decide between permanent and semi-permanent dyes. Permanent dyes offer long-lasting results, while semi-permanent options are less damaging and easier to adjust.

Step 3: Mix the Hair Dyes

Mixing hair dyes involves:

  1. Proportion: Use equal parts of each dye for consistency, unless a specific shade requires more dominance.
  2. Developer: Mix the dyes with the appropriate developer strength (usually 10 or 20 volume for subtle changes).

Step 4: Apply the Dye

Apply the dye mixture evenly:

  • Sectioning: Divide your hair into sections for even application.
  • Application: Start from the roots and work towards the ends, ensuring all highlights are covered.

Step 5: Rinse and Condition

After the recommended processing time:

  • Rinse Thoroughly: Use lukewarm water to rinse out the dye.
  • Condition: Apply a deep conditioner to restore moisture and shine.

Tips for Successful Hair Dye Mixing

  • Strand Test: Always perform a strand test to predict the final color.
  • Avoid Overlapping: Be cautious not to overlap dye on already processed hair to prevent damage.
  • Color Maintenance: Use color-safe shampoos and conditioners to maintain your new shade.

Common Mistakes to Avoid

  • Ignoring Undertones: Overlooking the undertones of your natural and highlighted hair can lead to clashing colors.
  • Skipping Strand Test: Omitting this step can result in unexpected color outcomes.
  • Using Incompatible Dyes: Mixing incompatible dye brands or types can lead to uneven results.
