Toner / Gloss

Formula: Toner from level 9 to level 10

Toning from level 9 (Very light blonde) to level 10 (Extra light blonde) is the final step that transforms a technical lightening into a refined, professional color. Here, the goal is to tone with slight lift, working on a light yellow underlying pigment base. The pale yellow underlying pigment at the target level is key to choosing the right toner family. A well-executed toner neutralizes unwanted warm tones and delivers the final reflect the client is looking for. The difference between a "correct" result and an exceptional one lies in understanding the interaction between the underlying pigment and the tone you deposit. We explain how to do it with precision.

Process steps

Underlying pigment evaluation

Examine the hair wet and dry. The starting level (9, Very light blonde) has a light yellow underlying pigment. Identify if the unwanted tone is uniform or has warmer zones. This will determine if you need a single formulation or zonal mixes.

Toner selection

To neutralize the light yellow background and reach level 10, you need Touch of violet to neutralize pale yellow. Mix the toner with 20vol (6%) developer in a 1:2 ratio. The low volume ensures pigment deposit without aggressive lifting.

Quick, even application

Apply on towel-dried damp hair from roots to ends. Work quickly: the toner starts acting immediately and you need uniform application to avoid patchiness. Use a wide-tooth comb to distribute the product evenly.

Visual time control

Process 15-25 minutes. Check visually every 5 minutes: the toner should deposit the desired tone without over-darkening. When the hair shows the target reflect, remove immediately. One extra minute can significantly change the final result.

Professional tips

Apply toner on damp hair, not soaking wet. Excess water dilutes the product and produces uneven deposit.
Timing is critical: check every 5 minutes. An over-processed toner can darken the result by 1-2 tones.
For a cooler finish at level 10, mix 2/3 desired tone + 1/3 ash violet.

Frequently asked questions

About this specific formula

How long does a toner from level 9 to 10 last?

A professional toner from level 9 to 10 lasts between 4 and 8 weeks, depending on hair porosity, wash frequency, and maintenance products used. Using sulfate-free shampoo and lukewarm water (not hot) significantly extends durability.

Is bleaching necessary before applying toner from level 9 to 10?

If the hair is not previously at level 9, you need to reach that lightening level before toning. Toner is designed to deposit tone, not to lighten significantly. Its main function is to neutralize and refine.

What to do if the toner comes out too dark?

If the toner darkened more than desired, wash immediately with a clarifying shampoo 2-3 times. Most semi-permanent toners lighten with washes. If it persists, a gloss bath with 10vol peroxide and shampoo (1:1:1) can remove the excess without damage. Never use bleach to remove a toner.
