Tactile hairs are associated with a sensory function and are much '''thicker and stiffer''' than other hairs. They are mainly found on the face and can also be referred to as '''''whiskers''''' or '''''vibrissae'''''. Their '''follicles are much deeper''' into the hypodermis than guard or wool hairs and possess a '''venous sinus and nerve endings with mechanoreceptors'''. During embryonic development, they appear before other hair types.

These hairs are mostly found on the '''face, near the eyes and on the upper lip'''. However they are also found in other areas, for example in a cluster on the '''carpus in cats''', in a tuft on a '''dogs' cheeks'''.
