Customer feedback highlights ease of use and perceived effectiveness, but reports vary on gray coverage, shade, scent, value, and how long color lasts. Some describe a natural black result while others find it too dark or say gray hairs remain. For buyers considering the listed 10–20 minute shampoo-style process, results appear unpredictable, and reports of scalp irritation make the advised pre-use skin test particularly important.

Mixed feedback
