Are you one of considering Melatonin could be dangerous for hair? Or even cause hair loss?

However, the opposite is true. 

Hair growth is a complex process regulated by many hormones and genes. Melatonin is a natural hormone secreted by the pineal gland, which has been known to slow down hair loss in some cases.

This article discusses whether Melatonin can be used for hair loss treatment.

Should I Try Melatonin for Hair Loss?

Yes, Melatonin is a powerful antioxidant that protects the cells from damage and can help prevent hair loss.

In recent years there has been an expanded curiosity about using Melatonin to stop or reverse hair loss. 

One study has shown that the topical use of melatonin can positively affect hair regrowth by stimulating hair follicles, but the study isn’t strong, and actually, it isn’t the main reason why Melatonin can helps hair growth.

Melatonin Reduces Too Much Cortisol: 

Stress might be a huge factor when it comes to hair loss. 

Besides, stress provokes other health problems, such as diabetes, high blood pressure, Alzheimer’s, as well as Depression.

Melatonin can help reduce cortisol levels by stimulating a mood regulation effect and encouraging neurogenesis (BDNF protein), eventually elevating sleep quality.

This is huge because anything that makes you sleep better can improve your overall health.

Can insomnia make your hair fall out?

Yes, insomnia can make your hair fall out.
Sleep deprivation can cause your body to produce extra cortisol. High levels of cortisol are released in response to stress, and it stops the production of healthy hormones like testosterone and estrogen, which can lead to hair loss. That’s why Melatonin is the key factor for hair health.

Stress Can Lead To Impair Nutrients Supplied

The hair follicle is a complex structure that needs to be nourished from the inside and outside. The cells of the hair follicle are constantly in need of nutrients for growth, repair, and renewal. 

These nutrients are supplied by hormones, vitamins, minerals, and water in the hair follicle’s blood vessels.

According to studies, acute and chronic stress levels inhibit important vitamins and proteins such as:

  • Hyaluronic Acids
  • Collagen(Cortisol may inhibit collagen synthesis. )
  • B-Vitamins 

B vitamins deficiency (including Biotin) is another important factor that might be the reason increase in hair loss caused by stress. 

Stress can come in many forms; how it affects your body is unique to you. There are many ways to deal with stress, such as meditation and Wim Hof Breathing. However, a more practical solution can help you get back on track: Optimizing Sleep (Melatonin).

What Are The Studies About Melatonin And Hair Growth?

Ton’s of studies showed that Melatonin counteracts Cortisol, which we mention as the main factor of hair loss and protein breakdown. 

According to the study, Melatonin acts as an antioxidant that reduces oxidative stress, which might worsen hair loss (exposure to pollution, UV radiation, smoking, etc.). 

Mitochondria are the powerhouses that generate energy in cells and produce a variety of important molecules, including energy carriers and signaling molecules.

However, when Mitochondria are impaired, that leads to excessive oxidative stress and affects our hair health.

Optimizing Melatonin support Mitochondrial Health and trigger Mitochondrial Biogenesis. (Eventually leads to better health)

Melatonin As DHT Blocker

DHT is a hormone mostly found in prostate and hair follicles cells. When DHT binds to these cells, it can lead to hair loss. DHT also 

Melatonin can be a natural DHT blocker that can help prevent hair loss by reducing the cortisol hormone. However, there is no clear study about it. 

Other DHT Blockers:

  • Curcumin: Most people do not become aware that Curcumin potentially helps to get rid of excessive DHT, as well as supports blood flow, protects veins from damage, as well a boosted mood. 
  • Black Tea: The study showed that the caffeine found in black tea could reach hair follicles to block dihydrotestosterone (DHT), and Black Tea consumption, done on mice at Harvard University, decreased DHT levels by 72% and raised testosterone by 35%.
  • Saw Palmetto: Actually, it isn’t strong as others, but it can help reduce enlarged prostate and inflammation and slightly affect DHT.
  • Limit Creatine: There is not any relationship between hair loss and Creatine. Yet, one study showed that creatine overload might increase DHT levels by more than %30 percent. It’s better to limit creatine intake instead of completely avoid.

How Much Melatonin Do I Need?

The best way to optimize Melatonin levels is by reducing artificial Blue light at night and reducing the amount of EMF exposure. However, in some cases, you might need to use Melatonin supplements for acutely. 

The average adult needs between 3-6 mg of Melatonin daily to maintain good health. However, In my opinion, most of the population does not need more than 0.5 to 1 mg per day. 

As with any supplement, it is best to consult your doctor before taking more than the recommended dose of Melatonin.

Tips for Stimulate Hair Follicles on My Head

Here are some recommendations that will help to stimulate hair follicles.

  • Scalp Massage: Chinese people use massage for better health and longevity. On the other hand, scalp massage is an ideal way to reduce stress and helps in increasing hair follicles.
  • Protein-Rich Diet: Excessive activation Autophagy and lack of protein can cause hair loss in most people. Eating good amino acids prevents hair loss, promotes muscle growth, and supports the immune system by positive nitrogen balance. Plus, protein-rich animal foods contain b vitamins and zinc, which is another factor that might prevent hair loss.
  • Avoid chemical products or treatments: Chemical treatments such as bleach or dye can limit hair growth. Cautiously use heat styling products as well.
  • Use Coconut Oil: You can use hair follicles to repair themselves with natural oils such as Coconut oil and Almond Oil. However, for me, it’s not always the case. 

Test your Vitamin D and Zinc levels in order to reach optimum health and better quality hair. 

Zinc can promote the synthesis of Melatonin and other important hormones, including the Thyroid hormone.

Anything trouble with the Thyroid can cause hair loss and other health issues. 


Hormones are far strong signaling for health and longevity, and anything related to hormonal problems can be harmful to cells, including hair health.

Optimize Melatonin can be helpful as a more promising antioxidant to support hair health and better stress management.
