Abstract
A hair treatment kit comprises a hair treatment composition selected from the group of semi-permanent oxidative and/or direct dye hair colorant compositions, hair bleaching compositions, highlighting compositions, and combinations thereof, a reservoir for holding the temporary hair treatment composition, and an applicator fluidly connected to the reservoir for selectively applying the hair treatment composition to a targeted area of hair. Methods of applying the hair treatment composition comprise selectively engaging the applicator with a targeted area of hair, leaving the hair treatment composition in the targeted area for a time period, washing the hair treatment composition out of the targeted area, closing the reservoir to preserve remaining hair treatment composition for later use, and reapplying the hair treatment composition to the targeted area.
