With argan oil and natural keratin: argan oil and natural keratin moisturize the deepest layers of the hair and effectively protect the hair against damage. Oat extract is rich in vitamins B and trace minerals, which form a protective film and give the hair noticeably more strength and elasticity. | Free of: ammonia, PPD, resorcinol, silicone, paraben, and mineral oil. Hair dyes are also suitable for vegans, dermatologically tested, and cruelty-free. | "PIGMENT-LOCK" TECHNOLOGY: through a controlled oxidation mechanism and without the use of ammonia, the color pigments penetrate to the innermost layers of the hair and remain there. The hair shines for a long time in intense shades that do not fade. | CHOOSE THE CORRECT COLOR TONE: The final result depends on the original hair color. Natural tones provide ideal coverage for gray hair and allow for a natural result without red shine. Color tones should always be chosen, which are at most two shades lighter or darker than the natural hair color. | Instructions for use: Do not use coloring if the hair has recently been treated with henna or metallic dyes. Wait until the color has grown out. The exposure time for 100% gray coverage is 35-45 minutes depending on the strength of the hair.
