We all know that we shed out hair every day and then a new hair develops in the root. Hairloss (Alopecia) refers to hair fall from any part of the body which is beyond the normal. It most commonly affects the head, but other body parts can also be affected. There are different types of alopecia. Broadly they have been classified into scarring and non-scarring types. Among the non-scarring group, the most common are the Male pattern hair loss, Telogen effluvium, Female pattern hair loss, and Alopecia areata. Some less common causes of hair loss are drug-induced, pulling out of hair, fungal infection, hormonal abnormalities, and nutritional.
Scarring group of alopecia are less common and include Traction alopecia, Pseudopelade of Brocq, Connective tissue diseases, trauma, radiation, Lichen Planopilaris, and some genodermatosis.
Male and female pattern alopecia is the most common type of Alopecia. The major causes of alopecia are primarily genetics and hormones. In male pattern hair loss, there is receding of the hairline along with thinning of the hair and baldness at the vertex. In female pattern hair loss, the hairline does not recede, but there is a diffuse reduction in the hair density over the central part of the scalp along with thinning of the hair. Both of these conditions require long-term treatment.
Alopecia areata is the most common cause of patchy hair loss. In this, a patient notices a sudden appearance of patchy baldness. It generally affects scalp and beard but, other areas like eyebrows, eyelashes, and body hair can also be affected. It is primarily an auto-immune disease.
Telogen effluvium can be acute, following some illness, or it can be chronic when it persists for a longer period of time lasting beyond six months. In this type of hair loss, the patient often experiences excessive hair fall while the hair density is not reduced to a great extent.
A dermatologist would take a detailed history of your hair loss, do a clinical examination, some hair test (pull test) and trichoscopy to make the diagnosis. Blood investigations like hemogram, Iron studies, vitamin levels and hormonal tests may be needed in some cases. In cases of suspected scarring alopecia biopsy may also be indicated.
