Do my hair diagnostic
01. Know and understand your hair type 

How do I determine my hair type? 

Before choosing any product, observe your hair. The shape, thickness, texture (dry/oily), and porosity determine 80% of what will work for you.

Simple test of the natural shape

Wash your hair with a gentle shampoo, let it air dry without any product or manipulation. Observe :

 Smooth

 Roots-to-ends nourishment, naturally radiant. 

 Wavy 

 Slight to pronounced S-shape, prone to frizz. 

 Curly

 Defined, bouncy curls that are often lacking moisture.

 Curly/Coily

 Tight, very dense coils that shrink as they dry. 

 Quick test: fine, medium or thick hair? 

Take a clean, dry hair between your thumb and index finger, then gently slide it.

 Barely perceptible 

Fine hair

 Clear but flexible

Medium-length hair

Thick and durable 

Thick hair

 What is your hair type? 

Observe your roots and lengths a few days after washing.

Dry

Lack of shine, rough texture, split ends, quick drying. They need hydration and nourishment.

Normal

Supple, shiny, and generally trouble-free. They are well-balanced and easy to maintain.

Bold

Roots that quickly grow out again, loss of volume as early as the next day. Proper scalp cleansing is essential.

Mixed 

Oily roots + dry ends (a very common case).

All you need to know.

What is the difference between permanent and semi-permanent hair dye?

Permanent hair dye penetrates the hair shaft through an oxidation process. It permanently alters the natural color, covers gray hair, and can slightly lighten the natural base depending on the developer used.

Semi-permanent hair dye deposits pigments without significantly altering the hair's structure. It gradually fades with each shampoo and can refresh color, add highlights, or slightly darken the hair. It generally cannot lighten the hair.

How to choose the right oxidant?

The choice of developer depends on the desired result, the color used, and the condition of the hair.

  • 10 volumes (3%): color deposits, darkening, and certain demi-permanent techniques.
  • 20 volumes (6%): standard coloring, gray coverage, and limited lightening.
  • 30 volumes (9%): more significant lightening.
  • 40 volumes (12%): powerful lightening, reserved for products and techniques that allow it.

It is essential to follow the manufacturer's recommendations, as each brand has its own formulations and dosages.

Can you lighten hair that has already been colored?

Yes, but it requires special attention!

An important rule in hairdressing: a dye generally does not lighten another artificial color.

To lighten already colored hair, it may be necessary to use a bleaching product or a suitable color correction product.

Before any technique, a diagnosis must be carried out:

  • Check the coloring history.
  • Assess the condition and resistance of the hair.
  • Identify the artificial pigments present.
  • Determine the desired result.

A professional diagnosis makes it possible to choose the most suitable technique while preserving the hair fiber.

How to make your color last longer?

To maintain a bright and vibrant color, it is important to adopt a suitable routine.

A few essential tips:

  • Use a shampoo specially designed for color-treated hair.
  • Space out shampoos whenever possible.
  • Opt for lukewarm water rather than very hot water.
  • Regularly apply a nourishing mask.
  • Limit the excessive use of heat styling tools.
  • Use a heat protectant before blow-drying.
  • Protect your hair from UV rays.

A little professional tip: well-maintained hair retains its shine, softness, and color intensity better.
