SHIHUANUO Hair Dye Shampoo for Gray Hair — 520ml Dark Brown, 3‑in‑1 Ammonia‑Free Color & Conditioner

How quickly does SHIHUANUO cover gray hair?

The shampoo starts to deposit pigment within 10–15 minutes on dry hair and provides visible coverage after a single application. For stubborn white or heavily contrasting roots, a second short application can deepen coverage without extra chemicals.

• Apply to dry hair for best pigment uptake.
• Leave 10–15 minutes before rinsing thoroughly.
• Expect color longevity of about 3–4 weeks, depending on washing frequency.
• Repeat once if coverage is incomplete on first try.

Will this damage my hair or scalp?

SHIHUANUO uses a mild, herbal‑based blend rather than harsh ammonia or peroxide, so it’s formulated to be gentler than traditional permanent dyes. The added botanical extracts aim to strengthen strands and improve shine while the conditioning agents leave hair softer after rinsing.

• Herbal extracts: camellia, ginseng, macadamia, glossy ganoderma.
• Ammonia‑free and no developer needed.
• Conditioning agents included to reduce frizz and add shine.
• Perform a skin sensitivity test before first use.

How do I use it at home for the best results?

Using the shampoo is similar to a regular hair wash but applied to dry hair for effective coloring. Wear the included gloves, work the product evenly through roots and gray areas, let it sit 10–15 minutes, then rinse well and style as usual.

• Start with dry, unwashed hair for stronger color pickup.
• Put on gloves and apply evenly from roots to tips if needed.
• Rinse thoroughly to avoid staining skin or fabrics.
• Use weekly or as needed to maintain color depth.
