To use henna, it is recommended to wait 6-8 weeks after chemically treated hair. Usually the colour becomes more intense 2-3 days after dyeing. Apply as a mask: mix with hot water until it has the consistency of yoghurt, approx. Leave for 30 minutes, apply plenty to clean dry hair, wrap the head with plastic film and roll around an old towel; leave for up to 3 hours; rinse well with water. Improves the appearance of hair. Can be mixed with other plant powders. Pure henna gives the hair copper red tones or different shades of red, depending on the natural hair colour and method of application.
