BLEACHING

Understand the Process: Bleaching powder is mixed with h2o2, the strength of the hydrogen peroxide (H2O2) concentration determines the lightening. Never use stronger H2O2 than necessary. A 12% is the strongest and is only recommended for dark, healthy hair that needs to be lightened significantly.

Selection of Percentage and Duration: Choose a lower percentage with a longer exposure time (up to 60 min) rather than a higher percentage with a shorter exposure time. Available options include 1.5%, 3%, 6%, 7.5%, 9%, and 12%.

Mixing ratio: The standard is 45g bleaching powder to 90ml H2O2. For a milder effect on lengths and ends, you can add up to 40ml water to a full mixture.

Efficiency: 1.5% lightens about 1-2 tones, while 12% can lighten up to 7-8 tones. For Scandinavian hair, 6%, 7.5%, and 9% are usually sufficient, as thinner hair strands contain less pigment.

HAIR STRUCTURE

Pitch scale: Hair is made up of the primary colors red, yellow and blue. The amount of these determines the pitch of the hair. Our pitch scale ranges from 1 (black) to 10 (platinum blonde).

Substrate table: This table shows the underlying warm pigments in hair. When hair is lightened, the blue pigment disappears first, and the warm pigments (yellow, orange, red) become more visible. This explains the changes in hair color after exposure to sunlight or lightening treatments. When transitioning from dark to light hair, you will observe all of these shades.

NEUTRALIZATION WITH THE COLOR STARS:

💜Purple neutralizes yellow💛

💙Blue neutralizes orange🧡

💚Green neutralizes❤️

Primary and Secondary Colors: Yellow, red, and blue are the primary colors. Secondary colors, such as orange, violet, and green, are combinations of two primary colors. Complementary colors, which are opposite each other on the color wheel, are used for neutralization for a more neutral result.

Hair Zones
Hot Zone: Starts from the scalp and extends 2-3 cm outward. Lightens the most and attracts warm pigments the most.

Cold Zone: Starts after warm zone and lightens less. Attracts both warm and cool pigments.

Porous Zone: Includes dry lengths and ends. Attracts more pigment, especially cool shades, and can turn blue/purple with overuse of silver shampoo.

Tips for Even Color: Use a cooler color in the warm zone, and a warmer, lighter color in the cold zone for an even result.
