Look HERE for the precise step-by-step application ritual.
Wait at least 48 hours before shampooing; this gives the pigments time to react with air and attach to your hair. The color will reach its final shade within two days

It naturally sets thanks to the reaction with the air, with a definitive result within a few days.

Just with clear water. Be careful not to dry hair at too high a temperature so as not to 'burn' the color

Nous recommandons d’utiliser des produits et soins capillaires bio, sans silicones ni parabènes.

We recommend using organic products and hair care, without silicones or parabens.

The vegetable coloring coats the hair, makes it stronger, and can in some cases make it drier. If you notice that your hair is drier with each application, we recommend that you apply an after-shampoo treatment.

In the case of a maintenance plant color (roots), you can apply it only on the regrowth (while respecting the application time)

The application time varies depending on the color chosen. To color your hair with plants, you must be patient, because natural pigments have a long release time. Respect the application time, the success of the coloring depends on it.

The natural plant pigments react naturally with your hair, and the final color result depends on your hair’s structure, nature, characteristics, current color and ability to absorb color.
Results from plant-based dyes can’t be standardized. Any chemical modifications, such as chemical dyes, bleaching, balayage or highlights, increase the intensity of plant-based colors. When hair has been made more sensitive and the cuticles opened up, color can be different and more intense, since the hair “drinks” the color.
Take the time to conduct a test on a strand of hair to be sure of the results on your hair.
If you’ve had a conventional dyeing process, bleaching, highlights, balayage, a permanent blowout or straightening, wait four weeks before using Tresse and do a test on a lock of hair.
If you have more than 40% gray hair, the overall color result may be less intense.

It has a very specific smell (spinach/wood fire), which will also fade after 3 to 4 shampoos.

It can take 3 to 4 shampoos for the color to bleed through, while the excess pigment is being washed out. Be sure to dry your hair well before getting dressed, to avoid any colored halo on light clothes.

You have two options: Either give it time to work - plant-based color will gradually fade after 6 to 9 weeks. Or use a natural mask (e.g. white clay and coconut oil) to lighten a nuance that is too dark for your taste. This will not lighten the basic color of your hair but will rectify the shade a little.

Plant-based hair color is tenacious. If you respected the application time and the instructions, your hair color will "take".

When a formula contains indigo, we often notice on light hair (white/grey/blonde) right after application a tint that pulls towards green/khaki. Don’t be afraid, it will change. In a few hours, the indigo pigments will oxidize in contact with the air and will naturally return the desired brown shade.

We have designed our colorings to not 'turn'. It is possible that if you pre-pigment white hair, you may get very slight red highlights, which will also fade.
