Melatonin: Does it Promote Hair Growth?

Reading time -

In the world of personal care and aesthetics, hair health is often at the forefront of concerns. For many men, the first signs of thinning hair can lead to a desperate search for miracle cures and overnight remedies. Amidst the numerous shampoos, oils, and treatments available, melatonin has recently been touted as a possible game-changer in the fight against male pattern baldness. While melatonin is commonly recognized for its role in regulating sleep-wake cycles, there is a growing curiosity about its potential effects on hair growth.

So let’s examine the connection between melatonin and male pattern baldness, explore well-established methods to address hair loss, and wrap up by discussing how Phoenix can support your journey through its innovative telehealth platform.

The Melatonin - Hair Growth Connection

Melatonin, a hormone produced in the pineal gland, has long been associated with the regulation of sleep. However, recent studies suggest that it might have an intriguing role in promoting hair growth. While you might be reaching for that bottle of melatonin supplements already, it’s essential to carefully analyze the science behind these claims.

How Does Melatonin Work?

Melatonin production typically increases during the evening as it gets dark and decreases with the rise of the morning light, which helps to regulate your sleep-wake cycle. Its effectiveness in promoting sleep has led many people to use melatonin supplements to combat insomnia and jet lag. But what does this have to do with hair growth?

Researchers have found that melatonin is not just produced in the pineal gland but also in other areas, including hair follicles. This finding has been the basis for examining melatonin's possible role in hair growth.

Potential Benefits on Hair Growth

When it comes to understanding the benefits of melatonin on hair growth, it is essential to delve a little deeper into the science of it. As we mentioned earlier, melatonin may help extend the anagen phase of hair growth. But how does this occur?

Anagen Phase Extension

Melatonin appears to have a stimulating effect on hair follicles. In the anagen phase of hair growth, the hair follicles are actively producing new cells that will eventually form the hair shaft. This is the phase when your hair is growing the most, and it typically lasts several years. Some studies have suggested that melatonin can increase the expression of certain proteins that are associated with the anagen phase, thereby potentially extending this phase. This, in theory, could result in longer, healthier, and more robust hair growth over time.

Antioxidant Properties and Reduced Inflammation

Aside from its potential role in extending the anagen phase, melatonin's antioxidant properties might also play a critical role in hair health. Antioxidants are known to combat free radicals, which are unstable molecules that can cause damage to cells in the body, including hair follicles. By neutralizing these free radicals, melatonin may protect hair follicles from oxidative stress, which is believed to contribute to hair thinning and loss. Additionally, melatonin may also have anti-inflammatory effects, which can be beneficial since inflammation around the hair follicles is often associated with hair loss.

Improvement in Hair Quality

There is also evidence to suggest that melatonin may improve hair quality. Some users have reported that after using melatonin-infused hair products, their hair felt stronger, had more volume, and showed a decrease in greying. While more research is needed to confirm these anecdotal reports, they hint at the potential multifaceted benefits of melatonin for hair health.

The Caveats and Limitations

Despite the exciting possibilities, it is paramount to approach the use of melatonin for hair growth with an informed and critical mindset.

Early Stages of Research

First and foremost, the research on melatonin and hair growth is still in its nascent stages. Most of the studies conducted thus far have been small in scale and sometimes limited to in-vitro (test-tube) or animal models. While these studies can provide valuable insights, they don't always translate directly to effects in humans. For melatonin to be widely accepted and recommended as a hair growth treatment, more extensive and rigorous clinical trials need to be conducted.

Not a Cure for Male Pattern Baldness

It's also important to recognize that melatonin is not a magic bullet for male pattern baldness. Androgenetic alopecia is a complex condition that is largely driven by genetics and hormonal changes. The primary culprit in male pattern baldness is dihydrotestosterone (DHT), a derivative of the hormone testosterone. DHT binds to receptors in hair follicles and, in genetically susceptible individuals, causes them to shrink and eventually stop producing hair. Since melatonin does not directly address the hormonal causes of androgenetic alopecia, it is unlikely to be a cure-all solution for this condition.

Possible Side Effects and Interactions

Furthermore, like any supplement or medication, melatonin has the potential for side effects and interactions with other medications. While generally considered safe for short-term use, the long-term effects of melatonin supplementation are not well understood. Some individuals may experience side effects such as drowsiness, headaches, or changes in mood. Additionally, melatonin can interact with certain medications, including blood thinners and anticonvulsants. It is crucial to consult a healthcare professional before beginning any supplementation, especially if you are taking other medications or have underlying health conditions.

Established Methods to Address Hair Loss

While melatonin offers a glimmer of hope, when it comes to male pattern baldness, there are other well-known methods that have stood the test of time and scientific scrutiny. These methods have been effective for many individuals in not only halting the progression of hair loss but in some cases, even promoting regrowth.


One of the most widely recognized treatments for hair loss is Minoxidil. Originally developed as a medication for high blood pressure, patients and doctors noticed that it had a side effect of growing hair. Now, it's available as an over-the-counter topical treatment in the form of a liquid or foam.

Minoxidil works by widening the blood vessels, allowing more oxygen, blood, and nutrients to reach the hair follicles. This can revitalize shrunken hair follicles, increase their size, and prolong the growth phase of hair. Though it's not a permanent cure, consistent use of Minoxidil can be effective for many individuals.


Another popular treatment is Finasteride, which is an oral medication. It specifically targets male pattern baldness by inhibiting the enzyme that converts testosterone to DHT, the hormone mainly responsible for hair loss in men. By lowering DHT levels, Finasteride can slow down hair loss and, in some cases, promote hair regrowth. Like Minoxidil, the benefits of Finasteride are maintained only with continuous use.

Hair Transplants

For those looking for a more permanent solution, hair transplant surgery might be an option. During this procedure, a doctor moves hair from a dense area of your scalp to the area affected by baldness. While hair transplants can be more expensive and invasive compared to other treatments, they can offer long-lasting and natural-looking results.

Low-Level Laser Therapy

Another method that has gained popularity is low-level laser therapy (LLLT). This involves the use of lasers or light-emitting diodes (LEDs) to stimulate hair growth. Although the exact mechanisms are not entirely understood, it is believed that LLLT helps to increase blood flow and stimulate cellular activity in the scalp, encouraging hair growth.
