Abstract: A hair colorant device capable of separately housing two volatile hair colorant solutions. The hair colorant device has two compartments used to store, introduce and mix the hair colorant solutions. When combined the two hair colorant solutions may be applied to a person's hair.

Abstract: A disposable, solution-mixing hair colorant dispenser: tubular rear segment including first reservoir having rupturable front end; tubular middle segment including second reservoir having rupturable rear and front ends; tubular front segment including rear end and forward-projecting porous applicator. Rupturing member near adjacent ends of first and second reservoirs for rupturing both when first and second segments are engaged. Rupturing member near front end of second reservoir for rupturing same when second and third segments are engaged. Alternative rupturing members: double-ended between first and second reservoirs and single-ended attached to third segment; double-ended within second reservoir; single-ended within first reservoir and single-ended attached to third segment. Segments threaded for endwise engagement to seal segments and rupture reservoirs. Fluids mixed and dispensed through applicator.
