Use both hands, pushing the hair back with the thumb or index finger of one hand and holding it back while picking at the exposed skin with the nail of the thumb or index finger of the other. The chimpanzee can also use one hand, parting the hair in the same way and holding it back with the lower lip. Grooming may occur in bipedal, quadrupedal, sitting, or lying posture. Function of grooming includes appeasement, reassurance and reconciliation in addition to elimination of ectoparasites.
