A disposable eyebrow dye kit includes two separate primary components. The first component is an elongated container consisting of two compartments separated by a thin membrane. One compartment contains a hair developer, for instance hydrogen peroxide and the appropriate colored dye, and the second compartment contains a dye solution, like ammonia. The second component consists of a brush member with brush bristles and a protective cap over the bristles at one end and a connector component at the other end. In use, the brush component is inserted into the container where the protective cap punctures the membrane separating the two compartments. The solution in one compartment is allowed to mix with the solution in the second compartment to form the dye mixture which is to be applied to the eyebrows. The brush component is then withdrawn from the container, causing the cap over the bristles of the brush component to fall to the bottom of the container. The brush component is then used to apply the dye directly to the eyebrows. When the dying operation is complete, the kit may be disposed of.
