Our brown hair concealer is carefully formulated with glycerin, dimethicone, and glyceryl stearate. It's specifically designed for effectively covering bald areas, instantly improving your appearance and restoring confidence. The design seamlessly blends with natural hair strands. The application method is extremely convenient: 1. Pre-dye test: Always perform a skin sensitivity test before use. If redness, itching, burning, or other symptoms occur, discontinue use immediately and wash off any residue. 2. Ensure hair is dry before use. 3. Wear protective gear during application and apply face cream to areas that may come into contact with skin (such as face, neck, behind ears, and arms). 4. Apply the hair dye evenly to the hair, ensuring every strand is covered. Wait 15-30 minutes for the dye to fully penetrate the hair. 5. Rinse hair with water and blow-dry. It can also precisely correct hairlines, fill in sparse areas, sculpt a perfect face shape, add fashionable charm, and its long-lasting waterproof and sweat-proof formula maintains its concealing effect all day long, unaffected by sweat or rain, and long-lasting without smudging.Ingredients: Glycerin, Dimethicone, Glyceryl Stearate
