YUOLITA Hair Dye Shampoo for Men & Women — 10‑Pack Instant Black, Ammonia‑Free, 10–20 Min Coverage

YUOLITA 10 PCS Hair Dye Shampoo is an ammonia-free, plant-based instant black shampoo that covers gray hair in 10–20 minutes and provides natural-looking color that typically lasts 2–4 weeks.

This easy at-home solution blends gentle botanicals with color agents to deposit pigment on the hair surface without permanent chemical processing. Designed for both men and women, the formula focuses on quick application, scalp-friendly ingredients, and short processing time so you can refresh your natural black color between salon visits.

How quickly will my gray hair darken with this shampoo?

Most users see visible color change within 10–20 minutes of massaging the shampoo through wet hair. Results depend on hair porosity and how much gray is present; thicker or coarser gray may need the full 20 minutes for best coverage.

• Application time: 10–20 minutes
• Visible coverage: typically after first use
• Best for: surface-level gray and white strands

Is this hair dye shampoo safe for sensitive scalps and regular use?

YUOLITA’s formula avoids ammonia and emphasizes herbal extracts to reduce irritation compared with traditional permanent dyes. Because the pigment coats the hair cuticle instead of penetrating deeply, it’s generally gentler, but a patch test before first use is recommended for anyone with sensitive skin.

• No ammonia formula
• Contains plant extracts to nourish hair and scalp
• Surface-level dye reduces chemical penetration

How long does the color last and how does it wash out?

The deposited color typically remains until the colored hair grows out or fades over a few weeks; many users report 2–4 weeks of noticeable color depending on washing frequency and hair care routine. Color gradually lightens with repeated shampoos and returns to natural roots as hair grows.

• Longevity: usually 2–4 weeks
• Fade pattern: gradual with regular washing
• Maintenance: reapply as roots appear

How do I apply the shampoo for the best, most even coverage?

Wear the included gloves, apply the dye shampoo to wet hair, and massage thoroughly to ensure pigment reaches all gray areas. Leave on for the recommended time, then rinse well and comb through; repeating on stubborn gray areas can improve uniformity.

• Use gloves provided for clean application
• Massage evenly from roots to ends for full coverage
• Rinse after 10–20 minutes and comb to distribute pigment

Who is this for: YUOLITA 10 PCS Hair Dye Shampoo is intended for adults—men and women—seeking a fast, cost-effective way to mask gray hair without salon visits or strong permanent dyes. It’s suited to people wanting temporary, natural-looking black coverage, those with sensitive scalps who prefer ammonia-free options, and anyone needing an easy at-home refresh between longer-lasting color services. If you have very light or chemically treated hair, expect variable results and consider a strand test first.
