Hair Loss Process


Hair is a matter of pride with most people. The appearance of a person’s hair reflects the personality of a person. If hair is unkempt, the person is considered to be sloppy and untidy. A person who is well turned-out with well-groomed hair will however be considered to be smart and neat. Therefore, with so much importance being attached to the hair on a person’s head, it can be understood that hair loss is taken very seriously. Here we shall take a look at the hair loss process in order to understand it better which should help to deal with this problem.

Factors that Cause Hair Loss

There are three major factors which contribute to the hair loss process:

  • Hair loss through age
  • Hereditary factors which contribute to hair loss
  • The presence of dihydrotestosterone (DHT) in the follicles of the hair

Hair Loss with Age Progression

  • As a person moves into the twenties, there is a tendency to lose more than average hair.
  • This leads to an appearance of thinning of hair.
  • This thinning may progress into baldness of the scalp or it may not.
  • This depends on the next point to be discussed – whether the person has baldness in their genes or not.

Heredity Factors

  • If a person has inherited genes of hair loss or baldness, the hair loss process is likely to set in by the time the person crosses twenty years of age.
  • Hereditary hair loss is known as “Androgenetic Alopecia” which is a scientifically proved reason for hair loss.
  • Hereditary hair loss can be inherited from either parent and does not have any limits with regards to ethnicity. This type of hair loss may skip generations and then, it may not. However, if this aspect exists for a person, then it is possible to plan on how to deal with the problem in the years to come.

Dihydrotestosterone (DHT)

  • It is a form of highly active testosterone.
  • This is present in a person in the foetal stage and during puberty.
  • DHT is believed to play a major role in hair loss.
  • DHT behaves in such a way that it treats the hair follicles as foreign bodies just the same way as the auto-immune response in the human body.
  • During this period, there is an increased sebum production from the sebaceous glands.
  • The cycle of hair growth is from 3 to 9 months.
  • In this period, the hair declines, falls out and regenerates.
  • Due to the action of DHT, the regenerated hair becomes thinner and gradually becomes too thin to survive in the scalp, resulting in baldness.


There is much research being carried out on the hair loss process. Though there is a lot of progress being made, the relation between baldness and the above mentioned processes are observed but still not fully understood. However, understanding these factors lead to preventing or at least suppressing hair loss.
