IIIMEIDU Black Hair Dye Shampoo 3-in-1 for Gray Hair — 500ml Herbal Color, Cleanses & Conditions

How quickly will I see gray coverage with this shampoo?

Most users notice an initial darkening effect after a single 15–20 minute application. Full coverage and richer tone develop immediately, with color deepening over the first few washes. Results vary by hair porosity and the amount of gray present.

• Apply on dry hair, lather in your hands, and distribute for even contact.
• Leave for 15–20 minutes for initial coverage.
• Color tends to hold for roughly three weeks before gradual fading.

Is the shampoo safe for sensitive skin and daily use?

The formula emphasizes herbal ingredients and aims to be gentler than traditional oxidative dyes, reducing irritation risk for many users. A patch test is recommended before first use to check skin compatibility. It’s intended for occasional color touch-ups rather than daily dyeing.

• Contains botanical components designed to clean and condition while depositing color.
• Patch test recommended before first full application to confirm tolerance.
• Suitable for both men and women when used as directed; not formulated for daily permanent dyeing.

How do I use IIIMEIDU shampoo for best, even results?

For consistent color, pump the product onto dry hair and work into a light foam on your hands before applying. Make sure strands are thoroughly coated and leave the shampoo on for the recommended 15–20 minutes. Rinse and style as usual.

• Start with dry hair for full coverage and easier distribution.
• Massage into roots and lengths to avoid patchy results.
• Rinse after 15–20 minutes; repeat use as needed for maintenance.

How long does the color last, and how should I maintain it?

Color typically remains noticeable for about three weeks, then gradually fades with washing and sun exposure. To extend vibrancy, use color-safe shampoos, limit hot-water washes, and avoid prolonged UV exposure. Repeat applications keep tone consistent between shampoos.

• Expect around three weeks of visible color before noticeable fading.
• Use gentle, sulfate-free cleansers to prolong shade retention.
• Touch up as needed; avoid overuse to maintain scalp comfort.
