Follow the instructions included with the product for precise mixing ratios and development times. Mix the colourant and developer immediately before application, apply to dry, unwashed or lightly damp hair as indicated by the provided instructions, and ensure even saturation from root to tip. Monitor development time according to the initial hair colour and desired outcome, then rinse thoroughly and apply any neutralising or after-treatment recommended in the leaflet. Perform an allergy test 48 hours prior to use if you have not used oxidative hair dyes before.
Usage recommendations
For optimal and consistent colour results, perform a strand test to confirm the final shade and adjust development time as needed. Use appropriate protective gloves and follow safety guidance included with the product. If hair is heavily damaged or chemically treated, consider a consult with a professional colourist to select the correct developer strength and pre-treatment routines.
