MEIDU Black Hair Dye Shampoo 3-in-1 for Gray Hair, 500ml (Black) — Herbal, Gentle Conditioning

This 500ml bottle from MEIDU combines color, cleansing and conditioning into one easy step designed for both men and women. Formulated with plant extracts such as ginseng, the shampoo aims to darken gray strands while leaving hair softer and less brittle than traditional permanent dyes. It’s intended for temporary coverage that lasts several weeks and is meant to be simple enough for at-home application.

How quickly will I see results with MEIDU Black Hair Dye Shampoo?

Most users notice the new darker tone after a single 15–20 minute application, with full gray coverage visible when the product is spread evenly and rinsed. Results typically darken immediately and stabilize within a day or two.

• Apply evenly, leave on 15–20 minutes, then rinse.
• Coverage becomes most noticeable after the first wash.
• Color may deepen slightly over the following 24–48 hours.

How long does the color last and how does it fade?

The dye effect is semi-permanent: expect color retention for roughly 3–4 weeks depending on wash frequency and hair porosity. The shade will gradually lighten with repeated shampoos and exposure to sunlight, returning hair toward its natural tone.

• Typical wear: about 3–4 weeks under normal washing habits.
• Fades progressively; brighter shampoos and sun exposure accelerate fading.
• Touch-ups are quick—repeat the short application when regrowth appears.

Is the formula gentle on hair and scalp?

MEIDU’s formula emphasizes herbal extracts to minimize harsh sensations often associated with permanent dyes. It contains conditioning agents to help reduce breakage and leave hair feeling smoother, though an initial patch test is recommended for sensitive skin.

• Herbal ingredients like ginseng aim to nourish and add shine.
• No strong chemical odor reported compared with many permanent dyes.
• Includes gloves for safe at-home use; perform a skin sensitivity test before first application.

How do I use the 3-in-1 shampoo for best results?

Using this product is straightforward: wear the included gloves, apply evenly onto dry or slightly damp hair, wait 15–20 minutes, then rinse thoroughly. Treat it like a combined coloring and conditioning session to simplify your routine.

• Wear gloves, distribute product from roots to tips for uniform color.
• Allow the full 15–20 minute processing time before rinsing.
• Rinse until water runs clear; style as usual.

Who is this for? MEIDU Black Hair Dye Shampoo is intended for adults seeking an easy, low-commitment way to cover gray hair and darken hair without a multi-step salon process. It suits people who want a time-saving solution—combining dye, shampoo and conditioner—those with mild to moderate graying, and anyone preferring botanical-forward formulas. If you have a history of allergic reactions to hair colorants, are pregnant, or have recently chemically treated hair, consult a professional and perform a patch test before use.
