Hypertrichosis is the excessive growth of hair, with increased thickness, on any part of the body. It is different from hirsutism as the latter represents excessive hair growth in androgen-dependent areas like the upper lip, chin, chest, linea alba, thigh and axilla. 

Hypertrichosis may be localized/generalized, and congenital/ acquired. It is associated with a psychological impact on the child and parents since it creates cosmetic disfigurement. 

Currently, the treatment options are limited and unsatisfactory, which needs to be customized based upon the area, nature and amount of hair growth, age of the patient and personal preferences. 

In generalized hypertrichosis several hair removal methods can be utilized like shaving (conventional/electric), trimming, bleaching, waxing, chemical depilatories, electrolysis and laser hair removal.

Further, if hypertrichosis is associated with any syndrome, multidisciplinary management should be carried out to ameliorate associated systemic features.
