Onilyua Natural Light Brown Hair Dye Shampoo is a 3-in-1 herbal instant color shampoo that cleanses, conditions and covers gray hair for a natural light brown shade.

This gentle, plant-extract formula blends Polygonum multiflorum and black sesame to deposit color while nourishing the scalp. Designed for both men and women, the 16.9 fl oz bottle offers multiple applications and aims to restore an even, youthful-looking tone without ammonia-like odors. It’s vegan and cruelty-free, and intended for regular touch-ups rather than permanent chemical coloring.

How quickly will I see color results after using this instant shampoo?

Color develops during a single application; most users notice visible coverage after one session, with deeper tones after repeated use. Results vary by original hair color, texture, and how long you leave the product on.

• Apply to dry hair and massage for 15–45 minutes depending on desired depth.
• Rinse thoroughly—color sets as it dries.
• Repeat twice weekly for sustained vibrancy and fuller coverage.

Is this safe for sensitive scalps and what are the main ingredients?

The formula is plant-based and hypoallergenic, formulated without strong ammonia odors and designed to minimize scalp irritation. A 48-hour skin patch test is recommended before first full use to check personal sensitivity.

• Key botanicals: Polygonum multiflorum and black sesame for natural pigments and conditioning.
• Vegan and cruelty-free; designed to gently cleanse while coloring.
• Free from harsh smelling ammonia; does not cling to the scalp or create residue.

How do I use the 3-in-1 hair dye shampoo correctly at home?

No salon tools are required—this product is formulated for easy at-home application. Gloves are included; follow the timing guidance to achieve the shade you want and always rinse thoroughly.

• Wear the provided gloves and apply to dry hair only.
• Massage evenly to ensure full coverage, then leave for 15–45 minutes.
• Rinse with clean water; repeat twice weekly to maintain color and shine.

Can this shampoo fully cover gray hair and how long does coverage last?

The shampoo is formulated for high gray coverage and aims to mask grays effectively when used as directed. Longevity depends on hair type, washing frequency, and exposure to sunlight or chlorine; touch-ups help preserve the shade.

• Effective on a wide range of gray percentages—results vary by individual.
• Use two times per week to extend color retention and luster.
• Avoid excessive sun or harsh chemical exposure to reduce fading.
