Buy the grey coverage you use every week by the dozen.
Bigen Permanent Powder Hair Color is a 6g (0.21 oz) powder colour that mixes with plain tap water — no developer, no ammonia — and this is the twelve-packet case for shops that colour regularly. Because it is measured out per packet, you mix only what the client needs and waste nothing. The dozen pack is how barbershops keep grey coverage on the shelf without reordering monthly.
Twelve packets in one purchase, so a shop doing regular grey coverage stops running out.
No developer to buy or store — the powder activates with room-temperature tap water.
No ammonia, which means no harsh odour filling the shop mid-service.
Zero waste per service because each 6g packet is a single measured dose.
Long shelf life sealed — powder packets store far better than mixed liquid colour.

Questions Barbers Ask
Do I need a developer?
No. Bigen powder is mixed with room-temperature tap water in a non-metallic cup — no separate developer is required.
How much does one packet cover?
One 6g box covers short to shoulder-length hair. Longer hair may take two.
How long does it process?
Twenty to thirty minutes on non-chemically treated hair, or fifteen minutes on chemically treated hair. Total application and development should not exceed forty minutes.
Why Barbers Love It
Grey blending is a fast, high-margin add-on. Powder packets mean you can offer it without stocking developer, bowls of leftover colour, or a full colour bar.
