Hair Colour Numbering System | L'Oréal Professionnel UK (2024)

FAQs

What is the Loreal color numbering system? ›

The level system is made up of 10 numbers which help determine the depth level of your natural hair. 1 is black, 5 is light brown, 6 is dark blonde, 7 is blonde and 10 is the lightest blonde. Your L'Oréal Professionnel colourist will analyse your hair and assess your natural base colour in-salon.

The decimal part of the hair color number is crucial for understanding the tone of the hair color. It indicates the warmth or coolness of the shade. Even numbers (e.g., 4.0, 6.0) are cool tones, often described as ashy or cool, while odd numbers (e.g., 4.1, 6.1) are warm tones, often described as golden or warm.

The first digits in hair dye codes are between 1 and 10. Each of the ten color levels is appropriately named to indicate a particular degree of lightness or darkness. The higher the first number, the brighter the tone of the hair. (e.g., 1-black, 10- lightest blonde).

If your hair is dark brown or black, you're probably a level 1 to 4. If your hair is medium brown, you're likely a level 5 or 6. If your hair is a darker blonde or light brown, you're probably a level 7 or 8. And, if you have light blonde hair, you're likely a level 9 or 10.

What are RGB color codes? RGB defines the values of red (the first number), green (the second number), or blue (the third number). The number 0 signifies no representation of the color and 255 signifies the highest possible concentration of the color.

Levels of Developer

The most common volumes of developer are 10, 20, 30, and 40 volume. The volume relates to the strength of the developer, meaning the higher the number, the stronger the volume. 10 volume developer is commonly used with toners, while 20 and 30 are two of the volumes recommended for at home use.

The higher the number, the lighter the base colour will be e.g. 1.0 is deep black and 9.0 is a light blonde. The second number of the shade is always related to the reflect. The higher the number is, the warmer the reflect will be e.g. 1.0 is a deep black with no reflect and 4.5 is a light brown with a warm reflect.

The second two letters or numbers refer to the reflects that a hair color has - see below. "N" means natural. This is base color. "NN" means extra coverage. "A" or .1 means "ash"

On each Naturtint box, you'll notice that there is a code (made up of a number and letter) that identifies each particular shade. But what exactly does that code mean? Well, simply put, the number refers to the shade's color level and the letter represents the shade's tone.

Types of hair coloring

The four most common classifications are permanent, demi-permanent (sometimes called deposit only), semi-permanent, and temporary.
