The definition of Trichology is: "the science of the scalp and hair in health and disease".  A Trichologist is academically trained in the biology and disorders of the scalp & hair.

Trichology is the branch of medicine and cosmetology that deals with the scientific study of the health of hair and scalp.  Trichologists themselves are not normally licensed healthcare workers, although members of the medical profession can undertake courses and/or careers within Trichology.

Trichologists are able to advise on, diagnose and treat a wide range of hair loss, hair conditions and scalp problems.  Hair is a very sensitive 'barometer' to imbalances in the body - factors such as poor nutrition, medical or genetic problems, medication and stress can adversely affect their hair and scalp.
