AKOIIN Black Hair Dye Shampoo for Gray Hair, 500ml — 3-in-1 Ammonia-Free, Gentle Scalp, Long-Lasting Color

AKOIIN Black Hair Dye Shampoo is a 3-in-1 ammonia-free shampoo that gently dyes, conditions, and covers gray hair in a single 10-minute at-home wash for natural-looking black color.

This 500ml / 17.6 fl oz formula blends hair-washing with color-depositing and conditioning to simplify gray coverage for men and women. Designed to be gentle on the scalp, the semi-permanent formula uses plant extracts to reduce frizz and deliver a fuller-looking black shade that lasts up to about 60 days per application. Its rinse-and-go routine, low irritation profile, and included toolkit make it an easy salon-alternative for regular maintenance.

How quickly will I see the new color and how long does it last?

The color begins to appear after a single 10-minute treatment on dry hair and fully develops once rinsed and blow-dried. Results are semi-permanent and the manufacturer reports color retention for up to roughly 60 days depending on washing frequency and hair porosity.

• Apply to dry hair, wait 10 minutes, then rinse and blow-dry for immediate color.
• Typical wear: several weeks to two months before noticeable fading.
• 500ml bottle supplies multiple applications (estimated 2–10 uses based on hair length and coverage needs).

Will this product completely cover gray hair and work on beards?

Yes — the formula is formulated to provide full coverage of gray or white hair, restoring a natural black tone. It’s suitable for both scalp hair and facial hair, such as beards, giving even pigment deposit for blended, consistent color.

• Formulated for 100% gray coverage when used as instructed.
• Safe for beard dyeing to match scalp color for uniform appearance.
• Works on natural gray and on areas showing color separation from prior dyes.

Is the shampoo safe for my scalp and will it damage hair?

AKOIIN’s shampoo is ammonia-free and includes seven plant-derived extracts like ginseng, camellia, and rosemary to help nourish hair during color deposition. The product is described as low-irritation and non-sticky; it aims to reduce frizz while conditioning rather than stripping hair, though individual sensitivities vary.

• Ammonia-free, low-irritation formula with herbal fragrance.
• Contains botanical extracts to support smoother, less frizzy strands during coloring.
• Semi-permanent approach avoids the stronger chemicals used in permanent dyes.

How do I use it and how many applications will one bottle provide?

Usage mirrors a simple hair-wash routine: apply to dry hair, leave for 10 minutes, rinse thoroughly, then blow-dry. The 500ml bottle can deliver from a couple to several applications depending on hair length and how much gray coverage is needed.

• Step-by-step: apply to dry hair → wait 10 minutes → rinse → blow-dry.
• Included instructions and a dyeing toolkit help with even application and ease of use.
• One bottle lasts about 2–10 applications; short hair requires less product, long or thick hair requires more.

Who is this for: AKOIIN Black Hair Dye Shampoo suits adults who want a fast, at-home solution to cover gray hair without resorting to salon appointments or harsh ammonia-based dyes. It’s a practical pick for people seeking gentle, semi-permanent black color, those who prefer plant-extract formulas, or anyone looking to match beard and scalp color with minimal fuss. Avoid if you have known sensitivities to hair color ingredients; perform a patch test before first use.
