About the Symptom
Alopecia is hair loss that can affect the scalp and/areas on the face and body. It can be temporary or permanent and is caused by multiple factors including stress, genetics, medications, age, hormones. Alopecia is the absence or loss of hair on the scalp or the face or body, in an area where it is expected to be present. This condition can be localized or diffuse, temporary or permanent, and can affect both sexes and all age groups. Alopecia is a sign or symptom arising from multiple possible causes, and is broadly classified as nonscarring vs scarring. Some of the causes of hair loss can be stress, hormones, medications, hair styling habits, auto immune diseases and genetics factors.

Possible Causes
Generally, Hair loss can be related to:
- Alopecia Areata
An autoimmune disease where the body's immune system attacks hair follicles, causing areas of hair loss that are typically patchy and round in shape.
- Trichotillomania
A psychological disorder where a patient feels a strong, irresistible urge to pull out their hair. It can be caused by anxiety, stress, or simply as a habit built up over time.
- Male Pattern Baldness (Androgenic Alopecia)
A common type of baldness that occurs with age. In males, the hairline recedes along with hair loss on the sides and top of the scalp. In females, the condition is characterized by the progressive loss of hairs over the frontal and top regions of the scalp, causing a visible reduction in hair density. The exact cause is unknown, but hormones and genetics play an important role.
- Sheehan's Syndrome
- Follicular Mucinosis
- Kerion
- Vogt-Koyanagi-Harada Disease
- Muscular Dystrophy
- Systemic Lupus Erythematosus (SLE)
