Ophiasis

Ophiasis is a specific pattern of alopecia areata, a type of hair loss, that primarily affects the sides and lower back of the scalp. The term "ophiasis" comes from the Greek word "ophis" meaning snake, as the pattern of hair loss can resemble the shape of a snake.

Causes

The exact cause of ophiasis is unknown, but it is believed to be an autoimmune disease where the body's immune system attacks the hair follicles. This can be triggered by a variety of factors, including stress, illness, or hormonal changes.

Symptoms

The main symptom of ophiasis is hair loss in a band-like pattern around the sides and back of the scalp. The hair loss can be sudden or gradual, and the amount of hair loss can vary from person to person. Some people may also experience itching or discomfort in the affected area.

Diagnosis

Ophiasis is typically diagnosed by a dermatologist through a physical examination of the scalp. In some cases, a skin biopsy may be performed to confirm the diagnosis and rule out other causes of hair loss.

Treatment

Treatment for ophiasis can be challenging, as the condition is often resistant to therapy. Treatment options may include topical corticosteroids, minoxidil, anthralin, or immunotherapy. In some cases, a combination of treatments may be used.

Prognosis

The prognosis for ophiasis varies widely. Some people may experience complete hair regrowth, while others may have persistent hair loss. The condition can also recur in some individuals.
