Hypertrichosis is the condition that refers to an abnormal growth of hair. It can manifest as excessive hair growth in areas where hair is normally absent or as an increase in density or length in hairy regions. This condition can be congenital, meaning it is present at birth, or acquired later in life due to various factors, including hormonal changes, medications, or certain medical conditions. Understanding hypertrichosis is essential in barbering and cosmetology, as it may influence styling choices and treatments offered to clients.

Alopecia refers to hair loss rather than an abnormal increase in hair growth. Trichotillomania is a compulsive disorder characterized by the urge to pull out one's hair, leading to noticeable hair loss. Telogen effluvium involves a temporary form of hair loss occurring after stress, shock, or a traumatic event, which is also not related to an increase in hair growth.
