Hair loss without scarring of the scalp is a very common condition and affects most people at some time in their lives.
Medical professionals should distinguish hair loss from breakage of the hair shaft from hair loss due to decreased hair growth.
Common balding (androgenetic alopecia) occurs in men and women and is due to the effect of testosterone metabolites in genetically susceptible hair follicles.
Thyroid disease, anemia, protein deficiency, secondary syphilis, chemotherapy, and low vitamin levels may cause hair loss.
Alopecia areata is a form of hair loss produced by the autoimmune destruction of hair follicles in localized areas of skin.
Medications indicated for hair regrowth include minoxidil (Rogaine) and finasteride (Propecia).
Prevention of hair loss includes good hair hygiene, regular shampooing, and good nutrition.
Medical health screening for hair loss may include blood tests such as complete blood count (CBC), iron level, vitamin B, thyroid function tests (TFT), and a biopsy of the scalp.
