SHIHUANUO Dark Brown Hair Dye Shampoo 500ml — 3‑in‑1 Color, Herbal Gray Coverage & Conditioning

SHIHUANUO Dark Brown Hair Dye Shampoo is a 3-in-1 herbal color shampoo that gently covers gray hair while cleansing and conditioning for an even, natural-looking dark brown shade.

This 500ml dye shampoo blends six botanical extracts into a single-step routine to refresh color without the mess or chemical mixing of conventional dyes. Formulated for both men and women, it aims to restore darker tones, add shine, and leave hair manageable after each wash. Designed for at-home use, the product doubles as a cleansing shampoo and a conditioning treatment while gradually depositing pigment for up to three weeks per application depending on hair type and wash frequency.

How does this shampoo color gray hair without a complicated dye process?

The SHIHUANUO formula deposits color during a normal shampoo cycle, so you simply lather and rinse rather than apply a multi-step dye kit. Pigments and botanical agents work together to adhere to the hair shaft while cleansing, creating gradual but noticeable coverage.

• Use like a regular shampoo: wet, lather, wait a few minutes, then rinse.
• Color builds over repeat washes for fuller coverage.
• Contains pigments formulated for uniform dark brown results.
• Simple at-home routine — no gloves, bowls, or developer needed.

Which natural ingredients does it contain and what do they do?

SHIHUANUO combines six herbal extracts, including argan and camellia, to support hair strength and surface shine while adding color. These botanicals complement the dye pigments to help hair look healthier and feel smoother after use.

• Argan nut extract: helps strengthen strands and reduce breakage.
• Camellia extract: boosts color vibrancy and adds gloss.
• Additional herbal extracts: support scalp comfort and manageability.
• Conditioning agents: leave hair softer and easier to detangle.

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

Results vary by hair porosity and prior treatments, but most users notice a rich dark brown tone that lasts around three weeks per build-up cycle. Regular use as part of your washing routine maintains color depth and can extend coverage over time.

• Visible color typically lasts up to three weeks between builds.
• Use 1–2 times per week for maintenance, more initially for coverage.
• Frequent washing or strong clarifying shampoos may fade pigment faster.
• Works on natural and previously colored hair; results vary.

Is it safe, and who should perform an allergy test?

The formula is designed to be non-irritating, but individual sensitivities differ, so a patch test is recommended before full use. Avoid contact with eyes, mouth, and open wounds, and discontinue if irritation occurs.

• Perform a skin allergy test 48 hours before full application.
• Do not use on damaged scalp or open sores.
• Avoid eye contact; rinse immediately if product enters eyes.
• Keep out of reach of children and store in a cool, dry place.
