A Stylist's Guide to Coloring Hair Extensions

Coloring hair extensions opens up endless creative possibilities for your clients, allowing you to achieve custom looks that perfectly match their vision. However, working with extensions requires a different approach than natural hair. When done correctly, coloring hair extensions can elevate your artistry to offer personalized experiences to your client, but improper techniques can lead to uneven results, damage, or client dissatisfaction.

This comprehensive guide will walk you through the essential steps for successfully coloring hair extensions, from preparation to finishing touches. You'll learn the best practices that ensure vibrant, long-lasting color while maintaining the integrity of high-quality extensions like those from Prolonged Hair.

Preparing Hair Extensions for Coloring

Proper preparation is the foundation of successful extension coloring. Quality extensions like Prolonged Hair's ethically sourced human hair require specific preparation steps to achieve optimal color absorption.

Start by gently detangling the extensions using a wide-tooth comb or extension-safe detangling brush. Work from the ends toward the root to prevent unnecessary stress on the hair fibers. This step prevents tangling during the coloring process and ensures even product distribution.

Next, wash the extensions with a sulfate-free, pH-balanced clarifying shampoo. This removes manufacturing residue, oils, or any buildup that could interfere with color penetration. Prepare a lukewarm water bath in a clean basin, adding a small amount of clarifying shampoo. Submerge the wefts and gently agitate without rubbing or creating friction.

Rinse thoroughly with cool to lukewarm water until the water runs completely clear. Use distilled or filtered water if you're working in an area with hard water, as mineral deposits can affect color results. Blot the extensions dry with a soft microfiber towel—never wring or twist the hair, as this can cause matting and damage.

Allow the extensions to air dry until they reach 80-90% dryness before applying color. You can also use a blow dryer on cool or low heat settings to speed up the process while maintaining hair integrity.

Step-by-Step Coloring Process

The coloring process for hair extensions requires precision and attention to detail.

 Before applying color to blonde shades, prime the hair extensions by applying 20-volume clear developer for five minutes to lift any protective treatments and create an optimal base for color absorption. The clear format saturates more effectively than cream, ensuring even application throughout each strand.

PRO•TIP: Use a toner brush to apply the developer to the hair, as it provides superior saturation and will result in vibrant, more even results.

When formulating for hair extensions, mix your demi-permanent color and developer in a 1:1 ratio by volume.  For best results, use professional lines like Redken Shades EQ, which provide consistent, predictable results on extension hair.

Lay the extensions flat on a clean, color-safe surface. Apply the color mixture using a tint brush, starting from the mid-shaft and working toward the ends before addressing the root area. This technique prevents oversaturation near attachment points and ensures even color distribution. Work in thin, manageable sections and massage the color through gently with gloved hands.

Process the color for 20 minutes at room temperature for standard results, or up to 30 minutes for deeper tone penetration. Never exceed 40 minutes total processing time, as this can compromise the hair's integrity.

Best Practices for Coloring Hair Extensions

Several key practices will elevate your extension coloring results. Always perform a strand test before full application, as extension processing history can vary even within the same batch. This test reveals how the hair will react to your chosen formula and processing time.

Monitor the color development closely throughout the process. Some color lines process more quickly than others and can darken beyond your selected level if left unchecked. Keep detailed notes of your formulations and timing for future reference and consistency.

Avoid applying color directly to bonds, tape tabs, or attachment points, as pigments and developer can weaken adhesives or keratin bonds. When working with clip-ins or temporary extensions, pay special attention to the attachment hardware to prevent damage.

Never ball up or twist extensions during processing. This creates matting and prevents even coverage. Instead, keep the hair laid flat and organized throughout the entire process.

Color Selection and Correction Techniques

Understanding color theory is essential for successful extension work. The color wheel serves as your guide for both creating custom shades and correcting unwanted tones. Primary colors (red, yellow, blue) cannot be separated into other colors, while secondary colors (orange, green, violet) are created by mixing primaries.

When correcting unwanted tones, identify the unwanted undertone and select its complementary color from the color wheel. For example, if you're dealing with orange tones at a level 6, use blue-based toners at the same level to neutralize effectively. Using lighter colors won't fully neutralize, while darker colors may over-correct and create muddy results.

Consider your client's skin tone when selecting colors. Cool undertones pair beautifully with ash blondes, true reds, and silver tones. Warm undertones are enhanced by golden blondes, copper shades, and rich browns. Neutral undertones offer the most flexibility, working well with both cool and warm color families.

For clients requiring dramatic color changes, Prolonged Hair extensions can be safely bleached using products like Redken Flash Lift with Bonder Inside. Test results show that quality extensions can be lightened from level 5 to level 9 through two careful bleaching sessions while maintaining hair integrity.

Finishing and Aftercare

The final steps of your coloring process are crucial for locking in color and ensuring client satisfaction. Rinse the extensions thoroughly under cool to lukewarm water until the water runs completely clear. Apply an acidic pH-balancing conditioner or dedicated post-color sealer to restore the cuticle and lock in the color molecules.

Leave the conditioning treatment on for 5-10 minutes, then rinse again with cool water to close the cuticle and enhance shine. This step is essential for color longevity and overall hair health.

Gently blot the extensions dry with a microfiber towel, then allow them to air dry on an extension rack or blow dry using low heat with a diffuser attachment. Avoid using flat irons or curling tools for at least 24 hours after coloring to allow the color to fully stabilize within the hair shaft.
