Color & Blonding

Beautiful color begins with understanding your hair.

The Addendum Approach

From bright blondes and dimensional lived in color to rich brunettes, vibrant reds, gray coverage, and corrective color, our team specializes in creating customized color for every hair goal.

Beautiful color starts with healthy hair. Before we ever mix a formula, we take the time to understand your hair history, your lifestyle, your maintenance routine, and your long term goals. Every formula, placement, and recommendation is made with intention to create beautiful, dimensional color while protecting the integrity of your hair.

We work with multiple professional color lines, allowing us to customize every formula based on your individual needs, including ammonia free options for clients with sensitive scalps. Our lighteners contain built in bond protection technology to help strengthen and protect the hair during the lightening process while minimizing damage.

When appropriate, we may also recommend extensions as part of your color plan to create additional brightness, fullness, or dimension without unnecessarily overprocessing your natural hair. Because beautiful color isn’t just about the formula. It’s about creating the healthiest path to the result you’re after.

Most Requested

Our most requested color services include lived-in blondes, dimensional brunettes, balayage, highlights, root retouches and gray coverage, glossing services, and blonding transformations.

Most guests come to us looking for soft, dimensional color that enhances their natural features rather than dramatically changing them. Whether they’re maintaining gray coverage, brightening around the face, adding dimension, refreshing faded color, or transforming their overall look, every service is customized to achieve the most natural-looking result for their hair and lifestyle.

Root Retouch & Gray Coverage

One area we pay particular attention to is root retouches and gray coverage. Many people think a root touch-up is one of the simplest color services, but we believe it’s one of the most important. Rather than relying on a single color formula, we often blend multiple shades and reflective tones to recreate the depth, dimension, and natural variation that’s naturally lost as hair turns gray. The result is softer, richer, more natural-looking coverage instead of color that appears flat or muddy.

One of our favorite recommendations is pairing a Root Retouch with a Clear Gloss. While the root retouch refreshes new growth and gray coverage, the clear gloss restores incredible shine throughout the mid-lengths and ends, leaving the hair looking healthier, more vibrant, and beautifully refreshed.

Color for Extension Guests

For our extension guests, color is an essential part of maintaining a seamless result. Because extension hair is real human hair, it naturally fades over time, just like your own hair. We custom color and re-tone both the natural hair and the extensions whenever needed to keep everything looking seamless, dimensional, and beautifully blended. Since we developed Addendum Hair and work with it every day behind the chair, we understand exactly how our extensions respond to color and how to maintain them throughout their lifespan.

No. 09

Vibrant Reds & Coppers

Creating beautiful reds and coppers requires precision formulation and thoughtful maintenance. Our team specializes in creating customized copper and red tones that complement your complexion while maintaining richness, vibrancy, and shine. Because red pigments naturally fade more quickly than other shades, we typically recommend maintenance appointments every 4 to 6 weeks to keep your color looking its best. Between appointments, a Color Gloss is a great way to refresh tone, restore shine, and extend the life of your color.

Best For

  • Copper transformations
  • Rich reds
  • Dimensional auburns
  • Guests looking for bold, customized color

Clear Gloss

A Clear Gloss is perfect for anyone wanting healthier, shinier hair, even if you’ve never colored your hair. This zero damage treatment enhances shine, smooths the cuticle, seals the hair, and leaves it looking healthier and more polished without changing your natural color.

No. 11

Color Gloss (Toner)

A Color Gloss refreshes your tone between major color appointments. As your color naturally fades, unwanted warmth or brassiness can begin to appear. A Color Gloss restores your desired tone, revives shine, extends the life of your color, and keeps your hair looking fresh until your next appointment.

Best For

  • Eliminating brassiness
  • Refreshing blonde or brunette tones
  • Extending the life of your color
  • Adding shine between appointments

Recommended

4 to 6 weeks after your color appointment

NextNo. 12Root Touch Up→
No. 12

Root Touch Up

A Root Touch Up refreshes your new growth by covering gray and maintaining fresh, consistent color at the root. Most guests return every 4 to 6 weeks, depending on their rate of hair growth, gray coverage, and personal preference.

Our Recommendation

One of our favorite recommendations is pairing your Root Touch Up with a Clear Gloss. While your Root Touch Up refreshes your new growth, a Clear Gloss brings the rest of your hair back to life. It restores shine, smooths the cuticle, and revives the mids and ends without changing your color.

The result is hair that looks healthier, glossier, richer, and freshly colored from root to tip. It’s one of our most recommended combinations because it creates a polished, finished look without the need for a full color appointment.

Color Correction

We offer advanced color correction services, with every correction beginning with a thorough consultation.

Every guest’s hair history is different. Whether we’re correcting uneven color, banding, unwanted warmth, over-processed blonding, previous at-home color, or simply helping someone achieve a result they haven’t been able to elsewhere, we first evaluate the condition of the hair, its history, and what’s realistically achievable while maintaining the integrity of the hair.

Some corrections can be completed in a single appointment, while others require a more gradual approach. We’ll always create a plan based on what’s healthiest for the hair rather than rushing the process.

One specialty that sets Addendum apart is our ability to incorporate extensions into corrective color work. Extensions aren’t just used to add length. They can also become part of the solution. They can restore fullness to hair that’s experienced breakage, add density where hair has become compromised, and introduce brightness or dimension in areas that can no longer be safely lightened. By combining corrective color with customized extension placement, we’re often able to achieve results that color alone simply can’t.
