Rhapontic

Preparation instructions : 
In a large bowl, gradually add warm water to the powders until you have a relatively thick paste. Do not use metal utensils. Before applying to your hair, cover the mixture with plastic film and let sit for one to two hours so the colour can develop.

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 unwashed hair, strand by strand. When hair is thoroughly coated, wrap it all in plastic film and let set. The leave-on time will vary considerably depending on your hair's porosity and colour and the desired result (from one 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.

Beauty tip : 
For fine, sensitised or dry hair, you are advised to add 1 to 2 tablespoons of organic vegetable oil (castor, coconut, argan) or slightly melted shea butter to your mixture since henna can slightly dry out the hair fibre.
We recommend that you use the Centifolia no-rinse lotion with raspberry vinegar which, thanks to its acidity, "closes the hair cuticle" and adds shine.

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.

FAQ

As my hair grows, can I colour just my roots? Will there be a line as my hair grows?

Yes, it’s possible to colour just your roots. However, be careful: to prevent lines, you need to know the appropriate ratio of powder mixture that matches your colour, as well as the leave-on time, so you can reproduce it when you only want to colour your roots.

My scalp is sensitive and becomes itchy after using natural hair colour. What should I do? Try adding a spoonful of vegetable oil to the henna. You can also use a shorter leave-on time, since itching often occurs after leaving the product on for over 3 hours.

Henna tends to dry out my hair. What can I do to avoid this? Henna does tend to dry hair. When preparing the hair colour paste, add yoghurt (to make the paste more creamy) or a spoonful of vegetable oil (the best solution), honey, or vegetable glycerine. 

My hair colour is starting to become too red. What can I do to fix it? The more you use henna, the darker your hair will become. If you want to keep your hair lighter, once you’ve found your desired colour, mix the henna with neutral henna, or only colour your roots. 

How can I get the henna out of my hair? You’ll need to use a Detox mask to make the colour fade
