Healing alopecia

What is it?

As its name suggests, this type of alopecia derives from a scar that prevents hair growth in the affected area. This can be due to injuries or ailments caused by trauma or burns, but it can also stem from a disease of the scalp.

Sometimes the scar tissue is not visible as it evolves insidiously. In this case, hair loss is progressive. In other cases, the symptoms of scarring alopecia can be the itching, burning or even pain of the patient. Therefore, hair loss can be gradual or rapid, with related symptoms, depending on the type and cause of hair loss.

Who is affected?

This pathology affects women over 40 years of age to a greater extent. Although men can also suffer from it, since, especially alopecia derived from trauma, burns ... it can affect everyone.

This type of baldness is divided into two types:

  1. Primary scarring alopecia: In these cases, the hair follicle is affected by an inflammatory process derived from a scalp disease. Among the most common are:
  • Pilar Lichen Planus: It mainly affects middle-aged women. The patient suffers from inflammation around the hair follicles and hair loss. They can be asymptomatic lesions or cause itching or discomfort. The scalp is the most affected area, although any area can be affected, such as the armpits or the pubic area.
  • Fibrosing frontal alopecia (variant of Pilar Lichen Planus): It especially affects women after menopause, although it can also occur in men. It is a type of alopecia that is expressed in the form of hair loss on the front.
  • Pseudopelada de Brocq: The disease affects more white women, 40 years and older. It is a disorder characterized by the appearance of soft and irregular patches of baldness of flesh color, especially parietal regions and vertex of the scalp.
  • Discoid lupus: It affects more women in adulthood. It is an autoimmune disease that causes round hair lesions and, in some cases, scarring alopecia. Its development can lead to total or partial loss of hair, either on the head or the rest of the body. Its cause is unknown and affects tissues and cells

2. Secondary scarring alopecia: They are caused indirectly, by causes as a result of trauma, infectious diseases, burns ... that is, caused by various factors that cause damage to the scalp. Secondary scarring alopecia is divided into:

  • Caused by trauma: It is characterized by alopecia caused by the tear of the follicular units (due to avulsion); by traction or grip that pulls the follicular units (such as trichotillomania); or by thermal factors group burns on the skin that affect areas with body hair, for example, the face or scalp.
  • As a consequence of surgeries: Related to sequelae or damage to the skin or scalp from surgical interventions or treatments such as facelifts or other procedures.
