Onilyua Dark Coffee Brown Hair Dye Shampoo 16.9 fl oz — 3‑in‑1 Color, Gentle Gray Coverage

Onilyua Dark Coffee Hair Dye Shampoo is an all‑in‑one brown dyeing shampoo that covers gray hair and refreshes color in minutes without harsh chemicals.

Designed for people who want quick, low‑stress color refreshes at home, this 3‑in‑1 shampoo combines gentle cleansing, gradual color deposit, and conditioning in a single bottle. The Dark Coffee shade uses plant extracts and a milder formula to tint hair from root to tip, giving a natural brown finish that can last several weeks depending on hair type and care routine.

How do I use Onilyua Dark Coffee Hair Dye Shampoo properly?

Use the product like an ordinary shampoo but leave it on longer to allow pigments to deposit. Apply to dry or damp hair, work from roots to ends, wait 10–15 minutes for the color to develop, then rinse thoroughly. For more noticeable coverage, repeat application after a few days.

• Apply to dry or damp hair—start at roots for best coverage
• Massage evenly and leave 10–15 minutes before rinsing
• Use every 3–5 days to maintain shade; daily use is optional
• One 16.9 fl oz bottle covers multiple applications

Will this shampoo cover gray hair and how long does the color last?

Onilyua’s formula is formulated to reduce the visibility of gray strands on first use and can provide near‑complete coverage depending on hair texture and previous treatments. Color longevity varies—expect lasting results up to about 30 days with normal washing. Regular touch‑ups every few washes help preserve depth and shine.

• Visible gray reduction on first application for most hair types
• Color may last up to 30 days; frequency depends on hair porosity
• Gentle fading—reapply every 3–5 days or as preferred
• Works on a range of natural and chemically treated hair

Is the formula safe for sensitive scalps and will it stain my skin?

The upgraded formulation uses milder ingredients and natural extracts to minimize irritation while depositing color. It is designed to be hypoallergenic and non‑staining to skin when applied properly, but a patch test is still recommended for very sensitive users. Avoid contact with eyes; wash skin promptly if accidental staining occurs.

• Mild, plant‑based extracts reduce irritation risk
• Non‑staining when used as directed—wipe any excess immediately
• Patch test recommended for sensitive scalps
• Avoid contact with eyes and delicate fabrics during application

How does this product fit into my hair care routine?

Because it cleanses, colors, and conditions, the shampoo simplifies your regimen—no separate dyeing kit or conditioner is required after use. For best results, follow with a color‑safe conditioner on subsequent washes and minimize high‑heat styling to extend vibrancy. Use it as a maintenance wash to refresh tone between salon visits.

• Replacement for separate coloring sessions for quick touch‑ups
• No additional dye kit or immediate conditioner needed after rinsing
• Pair with color‑safe products to prolong shade intensity
• Great for in‑between salon appointments or gradual color change

Who is this for: Onilyua Dark Coffee is ideal for men and women seeking a convenient at‑home solution to cover grays and refresh brown tones without peroxide or complex application. It suits all hair types and ages who prefer gradual, low‑damage color updates, especially those wanting a natural dark brown finish with conditioning benefits.
