MEIDU Black Hair Dye Shampoo for Gray Hair — 500ml (16.9oz) 3-in-1 Color, Conditioner & Gentle Herbal Formula

MEIDU Black Hair Dye Shampoo is an all‑in‑one herbal formula that gently colors gray hair black while cleansing and conditioning in a single 15–20 minute treatment.

This 500ml (16.9oz) 3‑in‑1 shampoo from MEIDU combines hair dye, shampoo and conditioner with plant extracts designed to darken gray strands and restore a glossy, uniform shade. Formulated for use by both women and men, the product promises quick coverage with minimal odor and includes disposable gloves for neat application. Results typically last several weeks, and the formula emphasizes nourishment and softness alongside color enhancement.

How quickly will I see color and how long does it last?

Color develops during the 15–20 minute application and is visible immediately after rinsing. Expect the shade to remain for around 3–4 weeks, depending on hair type, washing frequency, and exposure to sun or chemicals.

• Application time: 15–20 minutes
• Visible color: right after rinse
• Typical duration: 3–4 weeks
• Longevity factors: shampooing frequency, sun exposure, hair porosity

Is the formula safe for sensitive scalps and damaged hair?

MEIDU uses a plant‑based blend intended to be gentler than strong permanent dyes, with no strong chemical odor. A patch test before first use is recommended to check for individual sensitivity; avoid use on broken or irritated skin.

• Herbal extracts for milder treatment
• No harsh chemical smell advertised
• Patch test recommended before first application
• Not for use on broken or inflamed scalp

How do I apply the 3‑in‑1 shampoo for best results?

Apply evenly with the included gloves, massage into hair to coat gray areas, leave for 15–20 minutes, then rinse thoroughly. The combined shampoo and conditioner step saves time and helps deliver color with softer texture immediately after use.

• Wear gloves provided to avoid staining hands
• Work product into roots and gray zones for even coverage
• Rinse well after 15–20 minutes for consistent shade
• Use weekly or as needed to maintain color depth

Will the shampoo change hair texture or add shine?

The herbal ingredients are chosen to nourish and strengthen hair, improving smoothness and shine while depositing color. Many users report softer, more manageable hair post‑treatment, as the conditioner component helps detangle and reduce frizz.

• Contains plant extracts for nourishment
• Conditions hair during coloring process
• Enhances shine and manageability
• Suitable for most hair types including treated hair

Who is this for: MEIDU Black Hair Dye Shampoo is aimed at adults seeking a convenient, all‑in‑one way to cover gray roots and refresh natural black tones without a multi‑step dyeing routine. It's a practical option for busy people, those who prefer gentler plant‑based formulations, and anyone wanting faster touch‑ups at home.
