The details, at your own pace

This kit containsBase + Colour and accessories
  • 100 g of pre-pigmenting Base + 100 g of Deep Chestnut Colour.
  • Two pairs of gloves and two caps.
  • A thermometer and an instruction leaflet.

You will need: a non-metallic bowl, a brush and a towel. The brush is sold separately. The quantity to prepare depends on hair length and density: 30 g for short hair, 50 g for shoulder-length hair, 100 g for long hair.

Application and precautionsChoose the application suited to your hair

Before any application, read the leaflet and carry out the preliminary sensitivity and colour tests. The colour cannot lighten hair.

1. Prepare your hair and your mixture

Wash without conditioner or treatment, detangle and towel-dry. Apply to damp hair. In a non-metallic bowl, gradually add water at 60 °C, checked with the thermometer: 100 g of powder for 300 ml of water. Wear the gloves and use the cap during processing.

2. Follow the case that applies to you

Light blond hair or more than 10 % white hair
Base 1 h, then rinse. Deep Chestnut Colour 1 h 30, then rinse. That is 2 h 30 of processing, plus preparation, application and rinsing.
Only with less than 10 % white hair, excluding light blond bases
Mix 50 % Base + 50 % Colour in a single 1 h 30 application. This is not applying the Colour on its own.

Around 10 % white hair or unsure? Ask for advice before choosing your application.

3. Rinse and let the colour develop

Rinse thoroughly with clean water. Avoid drying at high temperature. Wait at least 48 h before the next shampoo; the final tone develops after two days.

Precautions to read

Use on a healthy scalp and non-irritated skin. Do not use on eyelashes or eyebrows; do not inhale or swallow the powder. Avoid contact with eyes and stop if irritation occurs. Do not carry out a chemical treatment immediately after colouring. Do not colour after chemical straightening. Keep out of reach of children; not for use on children. Once opened, use the sachet within 12 months.
