SHIHUANUO Black Hair Dye Shampoo 520ml — Ammonia-Free 3-in-1 Gray Coverage, Conditioning Herbal Formula

SHIHUANUO Black Hair Dye Shampoo is an ammonia-free 3-in-1 shampoo that gently covers gray hairs while cleansing and conditioning for natural-looking dark hair.

Designed for men and women who want a fast, at-home way to reduce visible grays, this 520ml shampoo combines plant-derived actives with a color-depositing formula. It works as a shampoo, dye, and conditioner in one step, so you can save time without mixing chemicals. The product emphasizes surface-level color that washes out gradually, and its herbal components aim to smooth and strengthen strands while enhancing shine.

How quickly does it cover gray hair?

Results are visible after a single use, with progressive darkening over a few washes depending on hair type and the amount of gray. The formula deposits pigment primarily on the hair surface, so the initial effect is fast and touch-up friendly.

• Visible color after first application for many users
• Darkening continues across several washes for deeper tone
• Best applied to dry hair for beard touch-ups
• Individual results vary with hair porosity and original color

Is the formula safe and what are the main ingredients?

This shampoo is ammonia-free and built around botanical extracts rather than harsh dyes. Key plant-derived components like ganoderma (reishi) and ginseng are included to help condition and support the hair fiber while the color deposits. As with all topical products, a patch test is recommended to check for sensitivity.

• Ammonia-free, no heavy mixing required
• Contains ganoderma and ginseng extracts for conditioning
• Formulated to sit on the hair surface to reduce damage risk
• Perform an allergy patch test before full use

How do I use it and what routine works best?

Use the shampoo like a regular cleanser: apply, lather, leave for the suggested time, then rinse. For quickest coverage, follow the package timing instructions and repeat if a darker result is desired. It doubles as a conditioner, simplifying your routine to one step.

• Apply to wet hair; massage until lather forms
• Leave on according to directions for optimal deposit
• Rinse thoroughly; repeat for stronger effect if needed
• Can be used on beards—best on dry beard for targeted application

How long does the color last and will it suit different hair types?

The deposited color gradually fades with regular washing, with many users maintaining darker tones for around three weeks before reapplying. The formula is designed to work on straight, wavy, curly, and previously colored hair, distributing pigment evenly without creating stiffness or excessive build-up.

• Color typically lasts several weeks, fading gradually
• Suitable for all hair textures and most previously dyed hair
• Leaves hair smooth and shiny rather than brittle
• Reapplication recommended to maintain uniform coverage

If you have known sensitivities, test a small skin patch before full application.
