How does lack of sleep cause hair loss

There are mainly 2 impacts of hair loss due to less sleep that is Stress and hormonal changes. 

  1. The human brain produces a hormone named "Melatonin". NIH research states that the melatonin hormone helps to regulate a person's sleep cycle and while regulating it also increases the growth of hairs. Sleep has a direct impact on natural hormones in the human body. So, less sleep will reduce the amount of melatonin in the human body which results in hair loss.
  2. Stress is also one of the results due to lack of sleep. Research confirms that people having stress end up losing their hair. It is due to telogen effluvium. It results in the hair follicles falling earlier than normal follicles.
