You can adjust frequency based on your desired shade intensity.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is this black hair dye shampoo safe for chemically treated or colored hair?\u003c\/h4\u003e\n\u003cp\u003eA: The DR.DAVEY coloring shampoo contains no high-concern chemicals and is CPNP certified, making it a gentle option for most hair types. However, if your hair has been recently permed, bleached, or chemically treated, we recommend doing a small patch test first to ensure compatibility.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How many washes does one box of 10 sachets provide?\u003c\/h4\u003e\n\u003cp\u003eA: Each box contains 10 individual 25ml sachets, with each sachet providing one full application.
