When the intention is to change the color of hair, women can count on many options in dye brands, in addition to the variety of formulas and textures: in gel, cream, shampoo, powder, paste. And to choose an ideal dye color, you need to know how to match the color of the hair to the skin tone. But to choose the right color, one must understand the numbering of hair dyes.
The colors of the dyes are identified by numbers, essential to define the desired shade, as they correspond to the colors and their variations of nuances / reflections. Regardless of the brand and name the color receives, numbering is what will determine the end result.
A very common mistake is to buy the tincture according to the picture of the box which, in most cases, can be extremely frustrating since the result is not as desired.
This is because each hair reacts differently to the dye and it is also worth remembering that the number on the package indicates the color you can expect from the dye, but the result depends a lot on the original color of your hair. Anyone who is used to coloring the yarn needs to consider the last color applied and take into account that dye does not lighten dye.
Colors / Tones
The first number represents the base color of the dye (also called pitch height), defined by an international range of shades ranging from black to ultra-light blonde.
- 1 ? Deep Black / Ultra Black
- 2 ? Natural black
- 3? Dark brown
- 4? Medium brown
- 5? Light brown
- 6? Dark blonde
- 7? Natural Blonde / Medium Blonde
- 8? Light Blonde
- 9? Very Light Blonde
- 10? Light Blonde
- 11? Super Light Blonde
- 12? Ultra Light Blonde
Nuances / Reflexes
The second tincture number? the one after the point? corresponds to the nuances / reflections that are combined with the base color and are most visible under sunlight. The first number after the dot represents the primary reflexes and the second number the secondary reflexes.
Dyes that have the number zero after the base color number, such as 2.0, represent the dyes with the "natural" color, that is, without pimper or secondary reflections.
- 0? No reflection / Natural
- 1 ? Greyish blue
- 2 ? Violet / Angry (or Mate on some brands)
- 3? Golden
- 4? Coppery
- 5? Acaju
- 6? Red
- 7? Brown / Chocolate
- 9? Green / Matte (or Violet on some brands)
Thus, tone 6 with a 6 shade results in a dye 6.6, a dark reddish blonde.
Some brands define this color as "Intense Red", others as "Cherry Red". However, any tincture with this numbering will always be a dark reddish blonde. When the nuance number repeats in the dye (eg 6.66), it means that the reflection is intense.
And when there are two or more numbers before the period? In these cases, it means that the base color is not pure and has other shades, which provide varied effects. A 42.5 tincture, for example, would be a medium brown to black with auburn highlights.
