AKOIIN Dark Brown Hair Dye Shampoo 500ml — 30-Minute Ammonia-Free Color + Conditioning

AKOIIN Hair Dye Shampoo in Dark Brown is a 30-minute, ammonia-free shampoo that cleanses, colors and conditions to hide gray hair with a natural-looking result.

This all-in-one 500 ml bottle is formulated to simplify at-home hair coloring: it works like a regular shampoo but deposits dark brown pigment while conditioning the strands. The semi-permanent formula blends natural plant extracts and a low-odor herbal scent to minimize scalp irritation and reduce frizz. With a single application lasting up to about 60 days and enough product for multiple uses, it’s designed for busy people who want an easy, cost-effective alternative to salon visits.

How quickly will I see full dark brown coverage?

Expect visible color development in about 30 minutes when applied to dry hair. Processing times are standardized for most users, so follow the instructions for consistent results. For heavy gray or previously lightened hair, a single 30-minute session often delivers full coverage.

• Apply to dry hair and leave for 30 minutes before rinsing.
• Works on natural gray and regrowth from previous dye jobs.
• One bottle (500 ml) typically covers 4–12 uses depending on hair length and thickness.

Is this safe for sensitive scalps and does it contain ammonia?

The formula is ammonia-free and includes five botanical extracts such as ginseng root and ginger to soothe and nourish while coloring. It is designed to be low-irritation with a light herbal fragrance; however, patch testing before first use is still recommended. The product aims to minimize frizz and dryness compared with harsher permanent dyes.

• Ammonia-free, semi-permanent dyeing system.
• Contains plant extracts to help condition and reduce frizz.
• Non-sticky texture and mild scent for a gentler user experience.

How long does the color last and how often will I need to reapply?

AKOIIN’s color-fixing technology is formulated to maintain the dark brown shade for approximately 60 days after a single application. This longevity reduces the need for frequent touch-ups and makes the 500 ml bottle economical for repeated use. Results will vary with hair type, washing frequency and exposure to sun or chlorinated water.

• Color duration up to ~60 days per application.
• One 500 ml bottle can be used multiple times—estimate 4 to 12 sessions.
• Less frequent salon appointments needed—cost-effective for regular maintenance.

How do I use the shampoo to get the best results?

The process mirrors regular shampooing but requires a 30-minute wait on dry hair before rinsing. Follow the included instructions and use the provided applicator tools for even distribution, then blow-dry to assess final tone. For stubborn gray areas, ensure thorough saturation and consider repeating after recommended intervals.

• Apply evenly to dry hair, saturating roots and gray areas.
• Leave on for 30 minutes, then rinse and blow-dry for final color reveal.
• Use provided toolkit and follow safety/patch-test guidance.

Who is this for? AKOIIN Dark Brown Hair Dye Shampoo is suited to adults—men and women—seeking an easy at-home solution for camouflaging gray or blending regrowth without harsh chemicals. It’s ideal for people who prefer low-fuss routines, want to avoid frequent salon expenses, and value a gentler, conditioning formula that leaves hair smoother and naturally colored for weeks.
