Does Melatonin Provide Protection Against Hair Loss?

Hair has a unique growth cycle. These cycles are;

  • Anagen (growth),
  • Catagen (transition),
  • Telogen (rest) and
  • Exogenous (loss)

The main aim of hair loss treatment is to prolong the anagen phase. Melatonin extends this phase and thus positively affects the hair loss treatment. It also helps to reduce oxidative stress in the body thanks to its antioxidant properties. This situation prevents the hair follicles from being adversely affected by stress.

Melatonin Hormone & Hair Loss

Supplementing Melatonin is Important

Although the supplement of this hormone is generally used for sleeping problems, it is known to be a useful supplement for people who do not have this kind of problem. However, it should be noted that this supplement must be taken with the approval of a doctor.

Do not Prefer Artificial Lighting

The invisible blue light emitted from the screen of electronic devices such as computers, phones, and tablets slows down the secretion of melatonin. Therefore, it would be beneficial to stay away from these devices as much as possible. You can use low-light table lamps for your reading and writing needs.

Have a Quality Sleep Routine 

Known as the stress hormone, cortisol has an important place in the sleep cycle. In a healthy person, cortisol levels are low at night and high during the day. However, this situation may change due to excessive stress, and thus sleep routine may be disrupted. This in return negatively affects melatonin production. That is why it is important to reduce stress before going to sleep and to have a quality sleep routine to increase the level of melatonin.

Consume Foods Containing Melatonin  

To increase the level of melatonin naturally, it is necessary to consume foods rich in this substance. Some of those are banana, cherry, pineapple, white rice, egg, salmon, dairy products, and tomatoes.
