After applying the plant hair colour my scalp itches, what is the cause?Updated 6 months ago

The itching can be caused by the increased blood circulation and the nourishing herbs in the color. It stimulates the metabolism, which can manifest itself as itching. In this case, it goes away with the first hair wash.

However, if you also experience redness, swelling or a rash, you may be allergic to one of the powders.

If you are unsure, you can carry out an allergy test. To do this, mix a small amount of your shade and apply it to the crook of your arm or to the area of skin behind your ear. Cover the area with foil, rinse the mixture off with clear water after 60 minutes and observe the area for a day or two. If there is no reaction as described above, there should be no allergic reaction. If a rash or redness occurs, you should always contact a doctor.
