Abstract: A hairstyling comb particularly useful for applying streaks of highlighter to the hair comprises a hollow stem closed at one end and communicable at its other end with a reservoir of a viscous liquid to be applied to the hair. Discrete passageways are spaced along the length of the stem whereby its interior opens to discrete locations near the junctions between respective pairs of teeth of the comb. Concavities open generally laterally of the comb, each communicating with a respective one of said passageways and having a relatively greater cross-sectional area.
