Onilyua Dark Brown Hair Dye Shampoo — 3-in-1 Color Shampoo 16.9 fl oz, Gray Coverage & Root Touch-Up

Onilyua Dark Brown Hair Dye Shampoo is a gentle 3-in-1 color shampoo that gradually covers gray, refreshes roots, and leaves hair with natural dark-brown tone in one easy step.

This 16.9 fl oz bottle combines coloring, cleansing, and conditioning into a single at-home shampoo designed for men and women who want fast, low-mess gray coverage and root touch-ups. The formula uses milder, non-irritating ingredients and natural extracts to deposit pigment as you wash — no separate dyeing kit required. It’s intended for dry application and short processing time to produce a visible dark-brown result that can be maintained with regular use.

How does this shampoo hide gray hair without a full dye process?

The Onilyua 3-in-1 works by depositing color molecules during the washing step so strands pick up pigment while being cleansed and conditioned. Applied to dry hair and left for 10–15 minutes, the formula builds color more effectively than a typical rinse-out shampoo.

• Apply to dry hair, root-to-tip for even coverage
• Process 10–15 minutes then rinse for an instant color refresh
• Coloring and conditioning in a single product to reduce steps

Will this damage my scalp or leave dye stains?

The product is marketed with gentler, hypoallergenic components and natural extracts to minimize irritation compared with harsher permanent dyes. Proper application—applying on dry hair and rinsing cleanly—helps avoid staining skin or fabrics.

• Formulated to be low-irritant and suitable for most skin tones
• Non-staining claim when used as directed; avoid contact with clothing
• Patch test recommended for sensitive skin before first use

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

Results are semi-permanent and typically last up to about 30 days, depending on hair type and washing frequency. To keep color even and fresh, use the shampoo every 3–5 days or more frequently if you prefer stronger build-up.

• Visible effect after the first application
• Maintain color by reapplying periodically (every 3–5 days suggested)
• Daily use is possible for faster build-up; adjust to desired shade

Will it work on all hair types and for root touch-ups?

Yes — the formula is intended for all common hair textures and for both overall color refresh and targeted root touch-ups. It’s available in multiple shades including dark brown, coffee, black and maroon to match or deepen your natural tone.

• Suitable for straight, wavy, curly and coily hair textures
• Use concentratedly at the roots for quick touch-ups between salon visits
• Available in several shades to blend with natural hair color

Who is this for: Onilyua Dark Brown Hair Dye Shampoo is made for busy people who want a simple, low-mess way to cover gray and refresh roots without a full salon appointment. It’s especially useful for those who prefer gentle formulas, need an easy at-home solution for gradual color, or want a conditioning wash that also deposits pigment. If you have highly processed hair, very light blond hair, or severe scalp sensitivity, perform a patch test and consider consulting a stylist before use.
