SHIHUANUO Black Hair Dye Shampoo for Gray Hair — 500ml Ammonia-Free 3-in-1 Color & Conditioner with Herbal Extracts

SHIHUANUO Black Hair Dye Shampoo is an ammonia-free 3-in-1 formula that gently dyes, cleanses, and conditions gray hair to a natural black shade in one easy step.

If you want an at-home solution that hides gray strands without mixing dyes or using harsh chemicals, this 500ml shampoo combines herbal extracts with a color-depositing formula to simplify your routine. It is formulated to coat the hair surface for even coverage, includes botanical ingredients such as ginseng and Ganoderma lucidum for added nourishment, and is designed for use on all hair textures for results that can last several weeks.

How quickly will I see darkening results?

Most users notice visible color after a single application, with intensity increasing through repeat use. Results depend on hair porosity, original color, and whether hair is wet or dry at application.

• Visible darkening after one use for many users
• Stronger coverage with repeated applications
• Works best on dry hair for beard or spot touch-ups
• Can take longer on very light or heavily bleached hair

Will this damage my hair or scalp?

The formula is ammonia-free and meant to sit on the hair surface rather than penetrate the shaft, reducing chemical stress compared with permanent dyes. It also contains botanical extracts to help maintain moisture and manageability, though an allergy patch test is recommended before full use.

• No ammonia in the formulation
• Surface-depositing color minimizes structural damage
• Herbal extracts help retain softness and shine
• Perform a patch test to ensure scalp compatibility

How do I use it for best, even coverage?

Apply like an ordinary shampoo: lather into roots and lengths, leave on briefly as directed, then rinse. For heavier gray coverage, work in sections and repeat applications until the desired depth is achieved.

• Wet hair, or for beard touch-ups use on dry hair as instructed
• Massage thoroughly to coat each visible gray strand
• Leave on the recommended time, then rinse well
• Repeat every few washes or as color fades to maintain tone

How long does the color stay and how do I maintain it?

Color longevity varies by hair type and washing frequency; many users report natural black tones lasting multiple weeks. To preserve color, use sulfate-free shampoos, rinse with cool water, and limit exposure to strong chlorine or prolonged sun.

• Typical wear measured in weeks, not permanent
• Use gentle, color-safe cleansers to extend tone
• Avoid frequent hot-water rinses and heavy sun exposure
• Top up with the shampoo as color begins to fade

Who is this for: SHIHUANUO Black Hair Dye Shampoo is made for adults seeking a low-effort way to mask gray hair without harsh ammonia-based dyes. It suits men and women, straight or textured hair, and anyone who prefers a combined shampoo-conditioner-dye product for faster at-home maintenance. Avoid use on irritated scalps or broken skin, and always perform an allergy test before applying to the entire head or facial hair.
