MEIDU Black Hair Dye Shampoo 500ml – 3-in-1 Gray Coverage, Conditioning Herbal Formula (Black)

MEIDU Black Hair Dye Shampoo is a 3-in-1 herbal formula that gently colors gray hair black while cleansing and conditioning in one 15–20 minute treatment.

MEIDU's 500ml (16.9oz) black hair dye shampoo combines plant-based extracts with a convenient shampoo-conditioner-dye action to restore a darker, more uniform tone without a complex multi-step routine. Designed for both men and women, the product aims to conceal gray strands temporarily for about 3–4 weeks while leaving hair feeling softer and looking shinier. A quick skin patch test is recommended before first use to ensure compatibility.

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

Most users notice visible darkening after a single 15–20 minute application. Coverage performance depends on hair texture, porosity, and how many gray strands are present. Results typically last 3–4 weeks and gradually fade with subsequent washes.

• Apply for 15–20 minutes for best immediate results.
• Coverage duration: generally 3–4 weeks depending on washing frequency.
• Repeated applications can maintain or intensify the color.
• Use mild shampooing to extend the color life.

Is the formula gentle enough for regular use and does it damage hair?

MEIDU's formula emphasizes natural plant extracts to nourish strands while depositing color, aiming to avoid the harshness of permanent dyes. It acts as a conditioner during the coloring process to help minimize dryness and brittleness. Still, avoid daily use—treat it as a maintenance step to refresh color and keep hair healthy.

• Herbal extracts (including ginseng) help condition and strengthen hair.
• No strong chemical odor commonly associated with permanent dyes.
• Combines cleansing and conditioning to reduce extra product layering.
• Recommended patch test before first application to check sensitivity.

How do I apply MEIDU Black Hair Dye Shampoo correctly?

Application is straightforward: wear the included gloves, massage the shampoo through dry or damp hair depending on instructions, leave it for about 15–20 minutes, then rinse thoroughly. Even distribution and gentle massage help the formula reach gray areas for uniform coloring. Follow up with your usual hair care routine once rinsed.

• Use the provided gloves to protect hands and nails.
• Work the shampoo evenly from roots to tips for consistent color.
• Rinse thoroughly after 15–20 minutes to remove excess product.
• Repeat application as needed to maintain desired darkness.

Can both men and women use it, and which hair types is it suited for?

Yes — MEIDU Black Hair Dye Shampoo is formulated for all genders and a wide range of hair types, including straight, wavy, and lightly textured hair. It is meant for cosmetic color refresh rather than a permanent chemical change, making it suitable for people who want a low-commitment solution. Those with chemically treated or very porous hair should monitor results and adjust frequency accordingly.

• Designed for men and women seeking gray coverage with conditioning benefits.
• Suitable for most hair types; monitor on chemically treated hair.
• Great for touch-ups and routine color maintenance.
• 500ml size offers multiple applications for several weeks of upkeep.

Who is this for: MEIDU Black Hair Dye Shampoo is ideal for anyone wanting a convenient, herbal-based way to darken grays while shampooing and conditioning in a single treatment. It fits busy shoppers who prefer a low-fuss color refresh, users who want to avoid the stronger chemicals of permanent dyes, and people seeking an on-the-spot solution for a more uniform, natural-looking black tone. Remember to perform a skin patch test before first use and follow the included instructions for best, safest results.
