Study and science of hair and scalpTrichology is a branch of dermatology that deals specifically with the study of hair and scalp. Trichologists specialise in the diagnosis and treatment of the causes of hair loss and maladies of the scalp.
Trichological approach to hair lossHair consists of protein and grows from hair follicles in the outer layer of the scalp. Each hair goes through a life cycle – an active growth phase (anagen), a transitional phase (catagen) and a resting phase (telogen), when the hair is shed and a new hair starts to grow. Hair loss occurs when hair growth is interrupted, resulting in the thinning of new hair and premature or excessive hair shedding. There are many types of hair loss with different underlying causes. Common types of hair loss include male/female pattern hair loss (Androgenetic Alopecia), diffused hair loss (Telogen Effluvium), spot baldness (Alopecia Areata) and hair breakages (which can be due to cosmetic processing or hair pulling). The trichological approach to treating hair loss is to ascertain the causes of the condition, then to formulate a course of treatment aimed at treating the root causes to eradicate and/or restore healthy scalp and hair growth.
