To use it, place the comb horizontally at the root and pull it slightly towards the lengths, lifting the roots. Then, pull it out of the hair the same way, that is, it must be pulled out still parallel to the root. The more you comb the hair, from root to length, the more volume is added. It can be used at the roots only, with dry hair, to build volume without taking away definition from the lengths. For a look with messy curls or even black power, use the fork brush repeatedly from root to tip on dry hair. Always do it smoothly so you don't risk breaking the hair.
