Onilyua Dark Brown Hair Dye Shampoo — 3‑in‑1 Instant Color & Gray Coverage, 16.9 fl oz, Hypoallergenic Conditioning Formula

Onilyua Dark Brown Hair Dye Shampoo is an instant 3-in-1 color treatment that tints hair to a rich dark brown while cleansing, conditioning, and covering gray in minutes.

Designed for people who want a fast, low‑mess way to refresh or change their hair color at home, this shampoo-style dye combines gentle coloring agents and conditioning extracts to produce natural-looking dark brown tones. The 16.9 fl oz bottle delivers multiple applications and works on all hair types. It’s formulated to be hypoallergenic and easy to use: massage into dry hair, leave 10–15 minutes, then rinse for visible results without complex mixing or separate developer steps.

How quickly will I see color and gray coverage?

Results appear after a single use and intensify with repeated applications. Most users notice visible darkening and gray coverage after a 10–15 minute development time; full effect becomes more consistent after two or three sessions.

• Apply to dry hair for best absorption.
• Leave on 10–15 minutes, then rinse thoroughly.
• Repeat every 3–5 days to maintain tone; lasts up to about 30 days between refreshes.

Is the formula safe for sensitive scalps and all hair types?

The Onilyua formula emphasizes mild, non‑irritating ingredients and natural extracts to reduce scalp sensitivity and residue. It’s suitable for straight, wavy, curly or coily hair, but we recommend a small patch test if you have a history of color reactions.

• Hypoallergenic formulation reduces irritation risk.
• Free of heavy staining residues when rinsed properly.
• Works on natural and previously colored hair; patch test advised for chemically treated scalps.

How do I use this shampoo dye at home — any special steps?

Use it like a regular shampoo but apply to dry hair for stronger color uptake. Massage from roots to tips, allow the product to work for 10–15 minutes, then rinse until water runs clear; no separate developer or additional conditioner is required.

• Start with dry, detangled hair for even coverage.
• Wear gloves and protect clothing to avoid accidental staining.
• Rinse thoroughly; repeat application for deeper shade or stubborn grays.

How long will the color last and how should I maintain it?

The color can hold up for several weeks, typically up to 30 days, depending on hair porosity, washing frequency, and styling products. To prolong vibrancy, use sulfate-free shampoos, avoid excessive heat styling, and refresh color every few weeks.

• Expect gradual fade with frequent washing; refresh every 3–5 days as preferred.
• Use mild, color-safe hair care products to extend wear.
• Avoid chlorine-heavy pools and prolonged sun exposure to reduce fading.

Who is this for: Onilyua Dark Brown Hair Dye Shampoo is made for anyone seeking a convenient, low‑fuss way to cover grays or darken hair without salon time — suitable for busy professionals, people new to home dyeing, and those who want a gentle, conditioning option for regular color touch‑ups.
