What is a hair pick? A hair pick (sometimes spelled “hair pik”) is a type of comb that is flat and square-shaped, like a painter’s brush but with harder teeth. It is used for combing and grooming very curly, thick, or textured hair. As the hair pick has longer, wider-set teeth, it is the number-one grooming tool choice for curly hair types. It not only detangles with minimal tension and damage on the hair strand; it also helps lift from the root, creating big, voluminous hair.
