Rhapontic

The Centifolia dye powders have been rigorously selected to provide you with powders exceptionally rich in pigments. Rhapontic, or wild Rhubarb, revives the natural highlights of blond to light-brown hair and adds strawberry blond tones.

This powder is pure and additive-free.

Ingredient : Rheum Rhaponticum L.

100% pure and plant-based powder.

Preparation instructions :
In a large bowl, gradually add warm water (<50°C) to the powder until you have a relatively thick paste. Do not use metal utensils. Before applying, cover the mixture with plastic film and let sit for one to two hours so the colour can develop. Except for indigo, which must be added at the last moment, and mixtures containing indigo. After two hours, indigo no longer develops its natural pigments.

Approximate quantities to be used :
For short hair : 50 to 100g of powder
For medium-length (shoulder-length) hair : 150 to 200g of powder
For long hair (mid-back) : 200 to 250g of powder
For very long hair (hip-length) : 300 to 500g of powder

How to apply:
Apply a thick layer of the mixture preferably to clean hair, strand by strand. When hair is thoroughly coated, wrap it all in plastic film and let set. Keep your head warm using a towel. The leave-on time will vary considerably depending on your hair’s porosity and colour and the desired result (from 1 to 12 hours).
Rinse hair thoroughly until all residues have been removed. The final colour result will appear two to three days after application, which is the time required for the colour to oxidise. Do not use shampoo for 24 to 48 hours after the leave-on period to guarantee optimal colour.

Beauty tip:
We suggest using our no-rinse detangling lotion with raspberry vinegar that will close the hair’s cuticle to set colour better while also adding shine and suppleness. We then recommend using an organic, sulphate-free shampoo that will not dry out your hair so that the colour lasts longer.

Precautions for use:
• Do not apply henna or dye powder to hair that has been permed or chemically colour-treated in the last two months.
• Before colouring your hair, apply a detox mask.
• Protect areas of your skin likely to be coloured by henna or dye powder by applying a thick layer of a moisturising cream or vegetable oil (top of forehead, ear contour).
• Wear gloves when preparing and applying the mixture so as to not colour your hands.
• Do not use metal utensils to mix the henna so as to not alter the quality of the powder. Warning: the material used could remain coloured.
• Test on a hidden strand of hair before colouring your whole head. Wait for 24 hours to view the definitive result.
• Do not perm or chemically colour-treat hair if you have coloured it with natural henna in the last two months.
