Is a patch test required before using this permanent cream hair color, and how do I perform one safely?

Yes, a patch test is essential before using any permanent hair dye, including Fitocolor Cream Hair Color 4.0 Chestnut. The test checks for potential skin irritation, especially if you have a sensitive scalp or recent hair treatments. Mix a small amount of the cream (about a teaspoon) with the developer as instructed, then apply a thin line behind the ear or on the inner forearm.

Leave the mixture on for the full test duration specified in the package instructions, usually 48 hours. During this time, avoid getting the area wet and watch for any redness, itching, burning, or swelling. If any reaction occurs, do not use the product and consult a dermatologist. If no reaction appears, you can proceed with the full application.

Additional safety notes: if your scalp is particularly sensitive, if the hair has been recently lightened, or if you have used henna or other strong coloring agents, consider performing the patch test a few days earlier to monitor delayed responses. In case of doubt about compatibility with previous color treatments, a quick consultation with a professional hairdresser can prevent unexpected outcomes.
