Alopecia (Hair loss)

Hair loss is divided into normal and pathological. In normal hair loss, several strings of hair are lost every day which are replaced and re-grown. In alopecia areata, some of the hairs that fall out are not renewed, resulting in thinning of the scalp.

Hair loss occurs in both sexes, regardless of age, however the most common cause of hair loss is androgenetic alopecia. Female androgenetic alopecia also exists.

What factors is it due to?

  • Age
  • Androgens
  • Heredity
  • Significant weight loss
  • Psychological factors
  • Medical conditions (eg diabetes, lupus erythematosus)

Treatments for hair loss have improved in recent years and include topical or systemic medications, or both. Patients should contact their dermatologist so that they are properly informed and guided about the available treatment and control options, as well as the most up-to-date methods of hair transplantation.
