ABSTRACT:
This invention provides several iterations for dyeing individual hairs or hair tufts, and comprises a body with a dye cavity in which one or more dye partitions can be filled, where dye materials are pressed out through screw drive or compression means, and where the dye materials are protected from air until extruded, such that unused portions can be stored rather than thrown away. In a preferred embodiment the dye cavity contains dye partitions for dye material and developer, which are forced by pressure into a mixing spiral which mixes them together and applies the active mixture to a person's hair through either a top attachment or pincers, both of which are constructed of spongy material which soaks up the dye mixture from the mixing spiral. The invention also provides a latex tube which prophylactically isolates the dyed hair such that the dye does not spread in an undesired manner.
