Noncicatricial alopecia

Noncicatricial alopecia is a type of hair loss that does not lead to scarring. It is a common condition that can affect both men and women at any age. Noncicatricial alopecia can be caused by a variety of factors, including genetics, hormonal changes, and certain medical conditions.

Types of Noncicatricial Alopecia

There are several types of noncicatricial alopecia, including:

• Androgenetic alopecia: This is the most common type of hair loss, often referred to as male or female pattern baldness. It is caused by a combination of genetics and the male hormone dihydrotestosterone.

• Alopecia areata: This is an autoimmune disease that causes hair to fall out in small, round patches. The exact cause of alopecia areata is unknown, but it is thought to be triggered by stress or illness.

• Telogen effluvium: This is a temporary form of hair loss that occurs when a large number of hair follicles enter the resting (telogen) phase at the same time, causing hair to shed more than usual.

• Anagen effluvium: This is a rapid and severe form of hair loss that occurs during the growth (anagen) phase of the hair cycle. It is most commonly caused by chemotherapy or radiation therapy.

Symptoms

The main symptom of noncicatricial alopecia is hair loss. The pattern and severity of hair loss can vary depending on the type of alopecia. Some people may experience thinning hair, while others may lose their hair in patches or all over their scalp.

Diagnosis

Noncicatricial alopecia is typically diagnosed through a physical examination and review of medical history. In some cases, a biopsy may be performed to rule out other conditions that can cause hair loss, such as cicatricial alopecia or fungal infections.

Treatment

Treatment for noncicatricial alopecia depends on the cause and severity of the hair loss. Options may include medications, laser therapy, or hair transplantation. It's important to consult with a healthcare provider to determine the best treatment plan.
