HAIR DYES: THE DIFFERENT TYPES OF HAIR COLORS AND DYES

Highlights or Balayage can lighten the face but also fix certain issues: color gradation can give the impression of thicker, denser - or the opposite - lighter hair.

It is also possible to opt for semi-permanent hair dyes for temporary results and which allow hair to quickly restore its natural color. This type of dye can be a good option when looking to try out a new color and can help you make a definite decision, before moving on to a permanent hair dye.

It is important to fully understand the benefits and disadvantages of each color treatment so you can make an informed decision.

How do I know if my dye will change my hair or make it more sensitive?

If the dye is called " permanent", " ton tone on tone ", or " ammonia-free ", it uses a chemical process called oxidation that opens up the hair to color it.

This alters the nature of the hair, but also allows a long-lasting and intense color to be applied.

If you're looking for a temporary hair dye or better yet a plant-based hair dye, then your hair has less to worry about. By covering the surface of the hair, these oxidation-free hair dyes do not alter the hair. Nevertheless, you should continue to care for your it as you would colored hair!

Why choose a permanent hair dye?

Although more damaging to hair, permanent hair dye is the most common as it is the only one that applies the biggest changes: dramatically changing your hair’s natural color, whether that be making you hair darker or lighter, covering up to 100% gray hair, ensuring long-lasting color for up to several months.

But it has its disadvantages: the color is permanent, damaged hair is sensitive and  roots can appears from the hair regrowth.

Is ammonia-free hair dye more gentle?

Ammonia-free hair dye remains an oxidative dye that works by penetrating into the heart of the hair fiber so as to change its pigmentation.

However, the absence of ammonia means the color treatments are more gentle as the colorants are not as aggressive on the hair.

On the other hand, ammonia-free coloring allows for less of a dramatic color change: hair cannot be made lighter, can gray hair be completely covered.

It’s a great option if you are looking to add bold tones to your hair’s natural color, or blurring the  roots between two permanent hair dyes.

What does the tone-on-tone hair dye change?

With its low oxidation power, tone-on-tone hair dye causes less damage compared to traditional permanent hair dyes, but also provides less change: the desired shade depends on the natural color, but it can be used to subtly darken hair or hide the first gray hairs.

Its biggest advantage: the tone-on-tone color will fade when washed, avoiding the appearance of ' roots'.

How do I choose a gentler hair dye for my hair?

Oxidation-free hair dyes are gentler on the hair as they do not change its condition nor pigmentation. They simply cover the hair on the surface or diffuse pigments without absorbing or aggravating the hair fiber.

To dye your hair without damaging it, you can start with a temporary hair dye: oxidant- and ammonia-free, it works on the hair’s surface and blends quickly without streaks.

It does not change your natural color but allows you to add a temporary boost of radiance or to correct unwanted tones.

Gentle on the skin, plant-based hair dye does not contain any chemicals, only plant-based powders. It colors the hair by coating it on the surface and reveals its original color.

Its biggest advantage: it enhances and strengthens the hair, adds shine and vitality.

What hair dye should I use to cover gray hair?

Hair dye is often used to hide gray hair.

Up to 20% gray hair: the appearance of the first gray hairs found all over the head. Tone-on-tone hair dye or plant-based hair dye can be used to cover gray hairs at this point.

Between 20% and 50% of hair is gray: to hide them, permanent or plant-based hair dye is a good solution, applying the treatments for a longer application time.

Between 50% and 100% of hair is gray: permanent hair dye is the only coloring treatment option that covers a large number of gray hairs. But you can also decide to embrace your hair and embrace the silver trend!
