Last Updated: Jun 14, 2022

What is Hair Loss?

Hair loss, also known as alopecia or baldness, refers to a loss of hair from part of the head or body. Typically at least the head is involved. The severity of hair loss can vary from a small area to the entire body.

What are the types of Hair Loss :

The hair growth rate slows down as people age and is called alopecia. There are lot many hair loss types:

  • Involutional Alopecia: It is the natural gradual thinning of hair with age. There is an increase in the number of hair follicles that enter the resting phase and the other hairs become fewer and shorter.
  • Androgenic Alopecia: Both women and men can be affected by this genetic condition. Men who have this condition may start losing hair even in their teenage years. This is known as male: baldness. It is marked by gradual hair loss from the frontal scalp and the crown and the hairline receding. Women affected by this have hair thinning after their forties. It is known as female: pattern baldness and maximum hair loss happen near the crown.
  • Alopecia Areata: It usually has a sudden onset and leads to hair loss in patches in young adults and children. It may lead to total balding (alopecia totalis). In over 90% of people having this condition, the hair grows back within a few years.
  • Trichotillomania: It is observed most commonly in children. A person tears out their own hair because of this psychological disorder.

  • Scarring Alopecia: It leads to irreversible hair loss. Inflammatory conditions of the skin like folliculitis, acne, and cellulitis, result in scarring that destroys the hair’s ability to regenerate. Tightly woven hair and hot combs may result in irreversible hair loss as well.
