It’s a terrible feeling to think you “can’t” fix something because you don’t have the right product.

Although the color lines we use try to make things easy for us by providing a product for every scenario, it’s good to understand the complex issues your clients will commonly come in with so you can be educated enough to alter your formulas easily with even the most limited materials available.

Here’s what you’ll learn:

    • How to use Pure Tone Mix-In’s
    • How to Removing Color Buildup
    • The Protocol for Filling Hair
    • Simple Adjustments for Resistant Hair
    • Lightener and Minerals DO NOT MIX
    • Fixing an “over-toning” situation
    • Prepping for haircolor corrections
    • How to fix over toned hair
    • Blonde color correction

This lesson is all about the “when and why’s” of haircolor corrections. We will discuss the three ways to make a “Decolorizing Shampoo”, we will discuss the three ways to make permanent color stronger, and most importantly:

We will discuss why Minerals and Lightener Do Not Mix! It’s entirely possible that you will have a situation on your hands one day like this:

    • Boiling Foil Packets
    • Strong Sulfur Smell
    • Lightener turning to liquid when it touches hair

I’m going to tell you how to avoid this horrific chemical reaction by being able to spot the clients with the signs of heavy minerals or metal buildup. This whole lesson is critical, it can be reduced to one theme: When you are thoughtful about your formulations, and begin giving clients exactly what they need, they will never leave you! That’s real client retention.

After purchasing this lesson, my biggest piece of advice is to watch the video first, and then watch it again while answering the workbook questions. It’s important that you actually understand your answers so you can remember this information while working behind the chair.

This Single Lesson Purchase Includes 1 video lesson (45 minutes) and 1 workbook.

I’m a hairstylist and a haircolor curriculum creator. I know first hand that none of us receives the haircolor education we thought we would get in Beauty School, no matter how much we paid for it. When I graduated and passed my State Boards I knew virtually nothing about haircolor formulation.


Yet still 15 years later, newly licensed hairstylists continue to struggle like I once did with haircolor formulation because they are not being taught how to formulate haircolor, consult with a client, or build a loyal following.


I am bridging the gap between the Beauty School education you received, and all the things you need to know about haircolor formulation to help you thrive behind the chair quickly.


Every hairstylist deserves the chance to have a profitable career, regardless of the salon they work in or the brand of products they use. If you want to make more money, feel more confident with haircolor formulation, and get so popular with clients you have no choice but to keep raising your prices, you’re in the right place.

How can color education be brand-neutral?

It’s simple, color theory is just science and rules. Every color line will have their own nuances, but this is all the real information you need to get you up to speed and formulating confidently.


How to fix over toned hair?

If you have a client with over toned hair (maybe you were the one that did it) you cannot add another toner on top of it to fix it.  What that will do is make the combination of those colors darker, and less desirable than the initial desired end result.  In order to fix it, you can do a very quick decolorizing shampoo and pull out the undesired tones and then maybe you will need to re-tone it properly.


What is a hair color correction?

Technically every single hair color client you have is a color correction, you should always be assessing changes to the whole hair strand, not just the root.  However, some appointments are very specifically set up as a corrective appointment because the desired end result is so far away from the starting point.  Oftentimes you will need to do double or triple processing, and maybe multiple appointments.


How to fix patchy hair color?
Patchy hair color occurs for two reasons:  Improper application, or a formula that wasn’t thoroughly mixed so the color molecules didn’t develop evenly. The only way to fix it is to re-apply a new formula.
