How long does COSYAGE beard dye shampoo take?

The listed full cure time is 5 minutes. Plan to leave it on for that long, then rinse thoroughly.

No. It is listed as demi-permanent, so the color fades over several washes and needs reapplying to keep gray covered.

What shade is available?

Black is the only color listed. It is intended for dark hair and will look unnatural on light or red beards.

How much product do you get?

The bottle is 10.58 ounces, listed as 1 fluid ounce unit count. That is a large bottle for beard use and should last many applications.

Is it cheaper anywhere else?

As of November 7, 2026, the best new price is $15.99 at Amazon, and only one store lists it new. There is no second price to compare against.

Does it work on mustaches too?

Yes. The recommended uses include mustache grooming and gray coverage, not just beards.
