Can Melatonin Promote Hair Growth? – 6 Months Results

 

elatonin is a naturally occurring hormone that’s associated with sleep, but did you know current research also shows it may help with hair growth?

In this post, I’ll introduce you to melatonin and its uses.

First, I’ll breakdown the two major waysmelatonin is believed to help with hair growth.

Second, I’ll discuss the symptoms of a melatonin deficiency and the side effects of melatonin supplementation.

Last, I’ll share three natural ways you can increase your body’s melatonin levels.

What Is Melatonin?

Melatonin is a hormone produced within animals that regulates sleep and wakefulness. The hormone is produced by the pineal gland.

Melatonin's effect on the sleep-wake cycle

While our bodies do naturally produce this hormone, there are over-the-counter supplements available for individuals with insomnia. A low dose of the supplement, when taken orally, can promote healthy sleep patterns.

Interestingly, melatonin has also been shown to positively benefit hair growth in individuals with hair loss.

How Melatonin Promotes Hair Growth

While the exact mechanism for melatonin’s effects on hair growth aren’t known, we do know a few things about the hormone based on recent scientific findings.

It Induces Anagen Phase

There are three main phases within the hair growth cycle. They are:

  • Anagen (active growth)
  • Catagen (transition)
  • Telogen (rest)

In individuals with Androgenetic Alopecia (AGA), sensitivity to DHT can lead to miniaturization of the hair follicle. This occurs due to inflammation, and the hair strand is no longer able to protrude from the follicle.

This shortens the anagen phase and leads to hair follicle miniaturization associated with the condition.

There are many treatments – both internal and topical – that have been shown to effectively induce anagen phase hair growth in patients with AGA. In 2004, melatonin was added to the list of topical hair loss treatments thanks to a research study from Germany.

Forty women with AGA or diffuse alopecia were included in the study. The women were split into two groups (randomized). Group 1 received a daily application of 0.1% melatonin, and group 2 received a daily application of a placebo. This went on for 6 months.

Throughout the study, blood samples were collected and trichograms were performed to assess progress.

The most promising results were seen in occipital hair growth for females with AGA, and in frontline hair growth for females with diffuse alopecia:

The percentage of hairs in anagen phase after 6 months of treatment was significantly increased from before treatment, and it was also improved over patients who received placebo.

While the mechanism is not clear, researchers believe that this study proves that there is a component with melatonin that induces anagen phase in hair follicles.

It’s a Potent Antioxidant

Antioxidants are essential to the health of the body, as they help to combat free radicals.

Free radicals are rogue molecules. These molecules are incomplete, and therefore steal electrons from other molecules. The molecules they steal from are those that support surrounding structures, such as the skin, hair, and organs.

(Learn more about antioxidants for hair here.)

When the electrons are stolen, the surrounding structures begin to break down. This occurs as a natural part of the aging process (which is why hair thinning and wrinkles are prevalent as you age).

While the aging process can’t be stopped, antioxidants can help to slow the process (including balding).

Melatonin is a known antioxidant, and one that can effectively combat free radicals (and aging) in the body.

Signs of Melatonin Deficiency/Dysfunction

With more and more individuals interacting with their electronics and spending the majority of their day indoors, melatonin deficiency has become a common problem. This can result in some less-than-pleasant symptoms.

The main signs of melatonin deficiency include:

  • Insomnia
  • Restlessness
  • Lack of dreaming

These signs, however, can lead to more serious health conditions if not treated. For example, untreated insomnia can lead to:

  • Anxiety
  • Depression
  • High blood pressure
  • High cholesterol
  • Irregular menstruation
  • Blood clots
  • Heart arrhythmia

If you suspect you suffer from melatonin deficiency or dysfunction, you should consult with your physician. There may be an underlying cause of your deficiency that your doctor can most effectively help you address.

Side Effects of Melatonin Supplementation

While supplementing with melatonin can be beneficial, it of course has a few side effects that go along with it.

The use of melatonin supplements should be avoided (or closely supervised by a physician) if you have diabetes, high blood pressure, high cholesterol, depression, or a seizure disorder. Similarly, those with a bleeding disorder or those who’ve received a transplant should avoid supplementation.

If you’re pregnant or nursing, consult with your obstetrician prior to supplementing.

How to Naturally Increase Melatonin Levels

To boost melatonin levels and promote hair growth, you have a few natural methods at your disposal.

Take a Melatonin Supplement

Melatonin supplements are commonly taken by individuals with insomnia to induce sleep. However, even if you don’t think you have sleep issues, melatonin can still be a beneficial supplement.

However, I recommend you start off with a low dose.

As melatonin supplements are considered a nutritional supplement and not a medication, the dosages contained within these supplements can be quite high. This can mess with your body’s natural circadian rhythm and cause issues down the road.

If you go the supplement route, I recommend just 1mg of melatonin each night. This can be difficult to do with capsules, but tablets, powders, and even liquid forms can also be purchased.

Avoid Artificial Lighting

If you work in an office environment, this can be difficult. However, avoiding artificial lighting (and increasing natural lighting) can increase melatonin production.

The best time to do this is a few hours before bed.

Avoid electronics (television, computer, tablet, and cell phone) and instead focus on non-electronics activities. You can still use a table lamp or other soft light to do these activities (such as read, write, or do a puzzle).

If you can, I also recommend increasing your natural light “intake” during the day. This means leaving your blinds open and only using other forms of lighting when necessary. Additionally, you can use your lunch break to take a walk outside.

Consume Melatonin-Rich Foods

While melatonin is largely produced within the body, you can also consume it.

Melatonin occurs naturally in a number of foods. These include:

  • Tart cherries
  • Bananas
  • Pineapples
  • Goji berries
  • Tomatoes
  • Oats

While you shouldn’t eat immediately before bed, you can consume these foods throughout the day to naturally increase your body’s melatonin output.

Conclusion

While some hormones within the body (such as DHT) can lead to follicle miniaturization, others (like melatonin) can actually promote healthy new hairs.

This is why I believe it’s a good idea to consult with your doctor about any possible hormonal imbalances. With your hormones under control, you can then work to regrow your hair.

Of course, I also recommend you treat the problems (hormonal or otherwise) as naturally as possible.

 

27 Best Antioxidants For Hair Growth

Antioxidants help reduce hair loss and speed up hair growth, but which foods and supplements contain the most antioxidants for hair?

In this article you’ll discover my favourite 27+ foods, herbs, spices and supplements that are bursting with hair growing antioxidant power.

One thing that’s important to note however is that although many people are eating more foods that are rich in antioxidants, they might not be getting any benefit from them whatsoever.

If the antioxidant foods are poorly combined or enter a digestive tract that is ‘backed-up’ and already covered in mucus they won’t be much good at all. In fact they could even make the situation worse.

That’s why it’s so important when eating healthy food to consume them in the right combinations, and ideally you’ve undergone a 7 day detox which has thoroughly cleaned out your colon, so you can properly absorb all the goodness of the foods.

Often people are willing to spend plenty of money on the latest super-antioxidant food, like blueberries, but consuming them on a full stomach or with a poorly functioning digestive tractmeans they will just ferment in the stomach and become nutritionally useless.

 

Anyway let’s get into it!

It is well known that free radicals contribute to premature aging, and as such they can be considered one of the mechanisms through which hair loss can take place in men, aka male pattern baldness.

Especially when present in the scalp free radicals might not cause hair loss in the first place but they certainly speed it up.

Keep your eyes open for another blog post where you can learn about the special mixture which can be applied to the scalp to conquer free radicals, amongst other things and actively encourage fresh hair growth in the scalp.

However if they’re being produced in abundance from within the body then you’re fighting a losing battle.

Free radicals are formed when a weak bond of a molecule is split leaving an unpaired electron. This molecule is then left in need of another electron so it can become stable, but it must steal this from another molecule.

The result is a chain reaction of molecular damage (which leaves the cells in our bodies damaged and unable to function efficiently.) The faster our cells need to be repaired, the faster we age.

Smoking, pollution, radiation and inorganic chemicals found in our food and water all increase the number of free radicals in our bodies.

And this is where antioxidants come in. Antioxidants break the chain reaction of free radical damage by donating one of their own electrons.

When free radical damage occurs in the scalp then the result is often damage to the hair follicle where it exits the skin and this inevitably leads to hair falling out, and growing back less often.

Ok, so let’s get straight to the point. What can we do to stop free radical damage as much as possible considering the amount of pollution and inorganic chemicals that we come into contact with in our modern lives?

Basically we need to eat more antioxidant foods, in the right combinations and timings with a cleaned out colon and efficiently functioning digestive system.

Alma berries contain enormous amounts of antioxidants

These are the best ones you can buy, but remember to see the detox section to make the most of them, otherwise most of the ‘goodness’ will just be coming out the other end and into the toilet.

  • Spices: cloves, vanilla, turmeric, cinnamon, sage, etc.
  • Berries: goji, acai, raspberries, blueberries, blackberries, cranberries, strawberries, etc.
  • Nuts: almonds, walnuts, brazil nuts, pistachio, hazelnuts, etc.
  • Dried fruit: raisins, prunes, figs, dates, apricots, etc.
  • Beans and legumes: black beans, kidney beans, lentils, pinto, etc.
  • Fresh fruits and veggies: the more colourful the better, and try to keep it organic.

A note on nuts and seeds: Remember to pre-soak nuts and seeds 8 hours before you eat them.

If you don’t pre-soak your nuts and seeds a chemical inside them remains, which stops them being digested (e.g. eating themselves when they germinate), but the water activates the seed making it easy to digest.
