Redken Principles are the foundation of everything we teach and are at the heart of our commitment to helping salon professionals learn, earn and live better.

PRINCIPLES OF HAIRCOLOUR REDKEN PRINCIPLES

- Redken Principles govern everything we do—they’re fundamental truths or laws with natural consequences.
- Principles apply to haircolour, design, finishing, texture and business building.
- In haircolour, we use principles to explain science, formulation, placement and application.
- Principles are natural and become second nature once learned
Redken Artist Chiala Marvici takes you through hair: the canvas you work with, the science behind it and how it reacts chemically. It's a great resource if you encounter a challenge while colouring, or if you just want a quick refresher.

PRINCIPLES OF HAIRCOLOUR: WHAT IS HAIR?

- Hair is a canvas composed of a mixture of protein, moisture, lipids, pigment, minerals and carbohydrates in various proportions.
- The hair’s structure is divided into 3 areas: the cuticle, the cortex and the medulla.
- There are two types of natural pigment: pheomelanin and eumelanin. Everyone has a combination of both.
- The physical properties of hair are texture, density and condition. All are important to consider when formulating haircolour.
Want to understand how to better analyze hair before a haircolour service? Redken Artist Justin Isaac explains visual values, how to work with them and how they affect the hair’s natural level.

PRINCIPLES OF HAIRCOLOUR VISUAL VALUES AND THE LEVEL SYSTEM

- When analyzing hair for a haircolour service, it’s important to determine the hair’s natural level or its visual value, ranging from light to dark. - This is always the starting point for achieving desired haircolour results.
- Redken’s visual values chart is divided into 5 value ranges: lightest, light, medium, dark and darkest.
- Undertones are the warmth created during the lifting process. This is caused by the fragmenting of the natural pigment."
When formulating haircolour, Redken has principles in place to ensure your formulas deliver the results you want. Redken Artist George Garcia discusses best practices to lead you to successful formulations every time

PRINCIPLES OF HAIRCOLOUR PRINCIPLE BASED FORMULATION

- As part of your consultation, determine the natural level, or starting level, of the hair.
- Then determine the target level, desired level, percentage of gray and desired tonal result.
- Look for the undertone at the desired level to help determine the end result.
Gray hair requires a balance of brown and added warmth to maintain a natural look.
Select a developer based on your Redken haircolour brand, shade and level. 
Make adjustments based on the hair’s physical properties. If the hair is questionable in any way, it’s important to perform one or more pre-treatments prior to the haircolour service."
