ECOFAN Dexe Instant Black Hair Shampoo 10-Pack — Ready-to-Use Gray Covering, Plant-Based Formula

ECOFAN Dexe Instant Black Hair Shampoo is a ready-to-use 10-pack that quickly delivers natural-looking black color to cover grays and refresh hair for up to 30 days.

This concentrated shampoo dye combines plant-derived ingredients with a simple at-home application, giving both men and women an efficient alternative to salon touch-ups. Each single-use sachet works in minutes: apply on wet hair, massage, rinse, and reveal darker, glossier hair without complicated mixing or long waiting times. The formula is designed for temporary-but-durable color that fades gradually over several weeks, making it easy to repeat treatments on your schedule.

How fast can I get full black coverage with this shampoo?

The Dexe instant shampoo is formulated to deposit color quickly; most users achieve visible black coverage after a single 5–10 minute application. Processing time is short, so you can treat your whole head during a single shower session.

• Apply on wet hair and scalp, massage for 5–10 minutes.
• Rinse thoroughly until water runs clear.
• See immediate color payoff that deepens over the next hours.

Will it cover white or gray hair effectively?

This product is designed to mask white and gray strands with even black pigment. Results depend on hair porosity and starting color, but most users notice substantially less visible graying after application.

• Works best on light to medium gray and white hairs.
• One application typically reduces visible grays; repeat if needed.
• Blend with regular shampooing schedule to maintain coverage.

Is the formula safe for my scalp and hair health?

The Dexe shampoo uses plant-based components aimed at gentle coloring without harsh processing. It is not a peroxide or ammonia dye; however, perform a patch test if you have sensitive skin or a history of allergic reactions to hair color products.

• Natural plant-derived ingredients reduce aggressive chemical exposure.
• No need to mix chemicals — single-use sachets simplify application.
• Patch test recommended 48 hours before full application.

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

Color persistence is up to 30 days depending on hair washing frequency and hair care routine. The shade fades gradually with shampooing; most people reapply every 3–4 weeks or sooner if they want consistent intensity.

• Lasts up to 30 days under normal washing conditions.
• Fade rate varies with water hardness, shampoo type, and sun exposure.
• Use the included gloves to avoid staining hands during reapplication.

Who is this for: ECOFAN Dexe Instant Black Hair Shampoo is aimed at men and women who want a fast, budget-friendly way to hide grays and refresh their natural black tone without salon time. It's suitable for people seeking temporary but substantial color change, travelers wanting an easy touch-up solution, and anyone preferring plant-based ingredients over stronger chemical dyes. If you have very dark brown or previously colored hair, expect a subtle difference; those with light gray or white hair will see the most dramatic blackening effect. Always follow the included directions and perform a patch test if you have sensitive skin.
