Alopecia - Definition, Causes, Symptoms and Treatment

Alopecia simply means hair loss (baldness). Alopecia areata is a form of hair loss from areas of the body, usually from the scalp. Alopecia areata affects both males and females. Alopecia areata does not make you feel pain and does not make you feel sick. In 1-2% of cases, the condition can spread to the entire scalp (Alopecia totalis) or to the entire epidermis (Alopecia universalis). Some people may lose more hair. Rarely, the disease causes total loss of hair on the head or complete loss of hair on the head, face, and body. Alopecia areata usually starts with one or more small, round, smooth bald patches on the scalp and can progress to total scalp hair loss (alopecia totalis) or complete body hair loss (alopecia universalis). Alopecia areata is an autoimmune disease.

Androgenetic Alopecia

Androgenetic Alopecia

Androgenetic alopecia is the scientific term for male pattern baldness. Despite its name, this form of hair loss affects both men and women. In men, hair loss normally starts after puberty and affects the crown, the vertex and the frontotemporal region. There seems to be no involvement of the hair around the back and sides of the head. Progression of the condition often results in baldness. However, the condition is normally noticed only when significant hair loss has occurred and hairline recession is apparent. In women, hair loss is more diffuse and affects mainly the vertex, and women rarely suffer from complete hair loss.

What Is Acne, Different Types And What Causes It

Acne is a skin condition characterized by raised bumps or lesions that primarily occurs on a person's face, neck, shoulders, and back. Oil and dead skin cells plugging the hair follicles cause the raised bumps and lesions. Contrary to the opinion of many teenagers, acne is not a life threatening condition although some types of acne can lead to scars on the skin. For some people, acne can cause social isolation, depression, and anxiety due to concern about their appearance. The emotional issues usually subside in most cases without significant professional intervention.
