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

IIIMEIDU Black Hair Dye Shampoo is a 3-in-1 herbal shampoo that dyes gray hair black, cleanses, and conditions in a single 500ml bottle. IIIMEIDU's Black Hair Dye Shampoo combines coloring, cleansing, and conditioning so you can refresh your natural black tone at home without a multi-step salon process. Formulated for both men and women, the 3-in-1 formula uses herbal-derived ingredients aimed at gentle coverage and manageable shine. It’s presented as a convenient, time-saving option for people wanting to reduce visible gray quickly while keeping hair soft.

How do I use the shampoo to get even gray coverage?

Application is straightforward: work the product on dry hair, create a small lather in your palm, then spread evenly through the areas with gray. Allow the formula to remain on hair for 15–20 minutes to develop color before rinsing thoroughly. Follow the included directions and perform a patch test on skin prior to first use to check sensitivity.

• Pump shampoo onto dry hair and rub into a light foam in your hand.
• Distribute foam starting at roots toward gray ends for even tinting.
• Leave 15–20 minutes; rinse well until water runs clear.
• Perform skin patch test before initial application.

How long does the color last and how often should I reapply?

The product is designed to provide a lasting natural black shade that typically persists for around three weeks, depending on hair porosity and washing frequency. Reapply when gray begins to reappear or color fades, usually every two to four weeks for maintenance. Using a gentle, color-safe routine will help extend the visible result between applications.

• Expect roughly three weeks of visible color on average.
• Reapply every 2–4 weeks based on personal hair wash habits.
• Avoid harsh clarifying shampoos that strip tint faster.
• Use lukewarm water and color-friendly products to preserve shade.

Is this product safe and suitable for sensitive scalps?

The formula emphasizes herbal components intended to be milder than many permanent dyes, and it is promoted as suitable for both men and women without irritating skin in most cases. However, individual sensitivities vary; IIIMEIDU recommends conducting a skin patch test before first use. Do not use on broken or irritated skin and discontinue if you experience irritation.

• Contains herbal-derived ingredients for a gentler profile.
• Not intended for application on damaged or inflamed skin.
• Always perform a patch test before the initial use.
• Stop use and rinse immediately if irritation occurs.

Can this shampoo save me time and money compared with salon coloring?

Yes — the 3-in-1 format reduces steps by combining cleansing, dyeing, and conditioning so you can refresh color at home without frequent salon visits. The 500ml bottle offers multiple applications, lowering per-use cost compared with professional touch-ups. It’s a practical option for people seeking convenience with a straightforward at-home routine.

• 500ml bottle provides many applications for ongoing maintenance.
• One-step use replaces separate dye, shampoo, and conditioner steps.
• No multi-hour salon appointments required for touch-ups.

Who is this for This product suits adults who want an easy, home-based way to reduce visible gray and restore a natural black shade without complex color kits.
