For men who start losing their hair, one of the first questions on their mind is – why is this happening?

Everyone knows that a certain percentage of men go bald but not everyone knows the scientific reason behind it. It’s easy to blame factors such as stress and poor diet, and whilst they certainly play a role in the health of your hair, they’re not the primary culprit.

The role of DHT

  • Dihydrotestosterone (DHT) is a male sex hormone and is the main cause of . The reason that balding occurs is due to the hair follicle’s sensitivity to DHT, which causes them to shrink, or ‘miniaturize’.

The second type of trauma is emotional trauma that can occur due to surgery, illness or poisoning.
  • Medication – There are a number of medications that can cause hair loss, especially those for blood pressure, heart disease and diabetes.
  • Nutrition – It’s been shown that poor nutrition can cause hair to become weak and thin, however complete balding usually doesn’t occur.
