Take out the colouring powder in a plastic bowl and add 6-7 tablespoons or approx. 35 cc. water in it to make the paste. Make the paste so thick that it can be easily and gently applied on hair. Apply this paste on hair with a brush. Comb the hair after five minutes so that the paste should reach in the roots of hair. If any whiteness is observed apply more paste on that portion. Ensure that the paste is completely applied on hair. Wash the hair after 30 minutes of application with water. Later on wash with soap or shampoo, as you like.
There are two tests, viz. - strand test & hypersensitivity that can be done to check the particular shade of colour and whether the colour is suitable for a particular skin or not. The details of these tests are given below -
Strand Test should be performed as to preview the actual effect of a particular shade. Select some area of grey (white) hair. Prepare a small quantity of mixture, apply it and wash after 30 minutes to see the result. As per results you may leave the colourant for more than 30 minutes to get darker shade of a particular colour.
Clean and wash a small area of the skin behind the ear or upon the inner surface of the forearm using soap and water. Prepare a small quantity of paste, apply to the area and allow it to dry. After 24 hours wash the area with water. If no irritation, itching, reddening, swelling or inflammation is experienced in or around the test area, it may be assumed that no hypersensitivity to the colourant exists.
While using herbal hair colours, we advise our clients to follow certain safety instructions that are mentioned below -
- colour should be kept away from direct sunlight & preferably in a dark place.
- The packet of colour should be opened only when ready to use.
- The colour should be mixed only in a plastic or glass bowl and not metal bowl.
- The paste should be applied with the application brush.
- Paste should be used immediately after preparation, (within 4-5 minutes) other wise it may not be effective
- Take proper care to ensure that colour solution does not go into your eyes.
- The preparation should not be used for dying eyebrows or eyelashes as severe inflammation of eye may result. In case the paste gets into eyes, the same should be rinsed immediately.
