Sunlight is able to cure diseases and boost hair growth naturally by spurring the production of fumaric acid in the skin which is then used by the liver to produce ATP, the primary energy source for human cells. Sunscreen, on the other hand, disrupts reproductive hormones, increases our exposure to toxic chemicals that cause disease and it restricts sun exposure. A radical thought but maybe, just maybe—the sun can heal you.

Radical, Heretical Facts about Sunlight Exposure and Hair Loss


In a separate discussion, we’ve talked about the use of PUVA treatment for hair loss and red light therapy as a cure for hair loss, but in this discussion, we’re going to talk more directly about how sunlight can help you regrow hair. Sunlight, after all, contains full-spectrum light so it includes light in the red and infra-red spectrums. So it makes sense that sunlight exposure (without using sunscreen) would actually help you regrow your hair. But that’s not the end of the story in regard to sunlight and how and why it works to regrow hair.


How Sunscreens Cause Hair Loss Through Reproductive Hormone Disruption 


Most sunscreens contain xenoestrogens, or toxic, synthetic chemicals that behave similarly in the body like natural estrogens. Unfortunately, because xenoestrogens are synthetic, they don’t have the same molecular shape as natural estrogens or phytoestrogens (plant-based, naturally-occurring estrogens). As such, these xenoestrogens can kill estrogen receptors and wreak havoc on the entire body. 


Below is a list of examples of harmful sunscreen ingredients to avoid. This list is not exhaustive:


  • Oxybenzone / Benzophenone-3, Oxybenzone
    • Oxybenzone is an endocrine disruptor that lowers testosterone levels according to research. Oxybenzone is also associated with the development of endometriosis.
  • Octinoxate
    • Octinoxate is an endocrine disruptor that causes imbalance reproductive hormone levels. It also disrupts normal metabolic activities contributing to metabolic syndrome. Many countries have banned octinoxate–except the U.S. of course.
  • Homosalate
    • Homosalate is another endocrine disruptor. It causes allergic reactions and skin irritation.
  • Cyclopentasiloxane
    • Cyclopentasiloxane has been restricted in the EU. It is toxic to the reproductive organs and thus it is another endocrine disruptor.
  • Octocrylene
    • This ingredient is often contaminated with a known carcinogen (cancer-causing agent).
  • Octisalate
    • Octisalate disrupts the functioning of the immune system.
  • Parabens
    • Parabens include: benzylparaben, butylparaben, methylparaben, and propylparaben.
    • Parabens disrupt estrogen levels.
    • Paraben exposures are directly linked to breast cancer development.


Because reproductive hormone levels play an important role in hair loss and hair regrowth, it’s vital that you get rid of the sunscreen and detoxify your life if you’re serious about hair regrowth. If you use sunscreen and if you feel like you need sunscreen, opt instead for natural sunscreen options, like Burmese thanaka (which comes naturally from a tree). If you burn easily or if you plan to be out in the sun for a long period of time thanaka works very well to protect the skin. The Burmese people use thanaka daily to protect themselves from the harsh, hot sun in Myanmar and it works very well!

So let’s say that you throw away your sunscreens, detoxify your life, and you decide to spend 30 minutes per day in the sun to expose your scalp to sunlight. That’s great! But while you’re out in the sun, you should expose as much of your body as you can to the full-spectrum light of the sun. Why? Because when your skin is exposed to sunlight, a lot of important health-promoting nutrients are produced in the skin and in the liver.

Sunlight and Vitamin D for Natural Hair Regrowth: What You Need to Know

Vitamin D is heavily promoted by the media as a cure for practically everything. But I’m not here to tell you that vitamin D is a cure for hair loss. It’s not that straightforward. In fact, when administered by itself, as just a vitamin D supplement without its partner vitamin K2, vitamin D is very dangerous and in fact, toxic to the body. Vitamin K2 is a newly discovered nutrient and it behaves very differently in the body from vitamin K1 (the famous blood-clotting vitamin). You should never take vitamin D2 or vitamin D3 without vitamin K2 and you need to take these vitamins in the proper proportion. So check the ingredient label on your multivitamin and if it lists vitamin D without a listing for vitamin K2, stop taking it. Maybe even throw it in the trash and find a multivitamin producer that cares enough about its customers to stay current on vitamin research


In this article, we talk more about vitamin D and why the media and Big Pharma pushes for the public to take vitamin D as a stand-alone nutrient that supposedly cures everything. But we’re not trying to totally diss vitamin D. After all, the skin produces vitamin D naturally when the body is exposed to the full spectrum light of the sun. And vitamin K2 is found in grass-fed animal products, which essentially means that it is a vitamin that derives (indirectly) from chlorophyll, another sun-based nutrient. Vitamin D ensures that the body absorbs calcium from foods that we eat. But vitamin D is lazy and after absorbing the calcium. It puts it into soft tissues like the blood vessels or in the brain or in the organs. This causes calcification and hardening of the organs, the brain tissues, blood vessels, etc. As such, vitamin by itself can cause many diseases from dementia (calcification of brain tissues) to diabetes (calcification of the pancreas). Vitamin K2 is the vitamin that ensures that calcium goes into the bones and teeth. In fact, you can use vitamin K2 with vitamin D to remineralize your teeth if you have cavities or other kinds of dental problem. And you can take a vitamin K2/D3 supplement to cure osteoporosis and/or atherosclerosis or arteriosclerosis too. So vitamin K2 is this missing variable in the vitamin D equation that the mainstream media never mentions. So, before we talk about vitamin D as a medicine to regrow hair naturally, I have to preface the material with these facts


In the scientific literature, vitamin D is involved in the signaling pathways for hair growth and it also impacts the differentiation of hair follicles. But in the literature, there’s an inverse relationship between serum vitamin D levels and the following types of alopecia. So, in other words, too much vitamin D can cause the following types of hair loss:


  • Telogen Effluvium
  • Alopecia areata
  • Androgenic alopecia
  • Trichotillomania


On the other hand, a deficiency of vitamin D appears to be associated with scarring alopecia. But overall, studies have shown that vitamin D supplements promote hair regrowth naturally. There’s clearly a link between vitamin D and hair regrowth, but none of the studies into hair regrowth note the importance of vitamin K2 thanks to consensus based science and group think in the scientific field. So remember that it isn’t safe or wise to take vitamin D supplements by themselves even though the media says that vitamin D will cure all of your ills. Always make sure that you purchase a vitamin K2/vitamin D3 combo product instead. 

Understanding How Vitamin K2 Will Enhance Hair Growth

Okay, so we’ve talked a bit about vitamin D, which seems to affect hair regrowth perhaps through its effects on reproductive hormone levels. But what about vitamin K2? How can this nutrient help to regrow hair naturally?


Vitamin K2, as we mentioned above, changes the way calcium is distributed in the body. While vitamin D2 or D3 is able to capture calcium from food and ensure that our bodies absorb the calcium, vitamin K2 maps out where the calcium should go in the body. If you only take vitamin D2 or D3 as a supplement, your body is putting large quantities of calcium into your blood vessels, your pineal gland, your pancreas, and other soft tissues that are damaged by calcification. At the same time, if you only take vitamin D2 or D3 as a supplement, your bones and teeth are getting weaker and weaker. It’s a bad situation that can be remedied quickly if you simply start taking a vitamin K2/D3 supplement.


In terms of hair regrowth, when you start taking vitamin K2, you’re essentially opening up the blood vessels to the scalp which have been shut off from the blood supply by calcium build up in the blood vessels. Remember, hair growth happens in cycles, so while it only take 6 weeks to remove about half of the calcium from soft tissues in the body when you start doing vitamin K2 supplementation, it takes about 6 months to see the results of a natural hair regrowth medicine. The cyclical nature of hair growth means that the hair treatments you do today may not really start to become visible for 6 months. So keep this in mind and set a course to stick to a hair loss treatment protocol for at least 6 months before you decide whether to continue with it or not. 


Obviously, if you combine sunlight exposure with vitamin K2/D3 supplements that open up the blood supply to your scalp with something like red light therapy that has the ability to increase blood flow to the scalp and energize follicles, and if you also use topical medicines like peppermint essential oil and thymus peptide shampoos, you’ll increase the odds that you’ll be successful at regrowing your hair. 


Vitamin D is an important nutrient that plays a role in reproductive hormone production. We’ve already mentioned that imbalanced reproductive hormone levels play an important role as a cause of hair loss. If you’re suffering from hair loss, take a vitamin K2/D3 supplement daily, but you should also know that sunlight directly impacts your liver as well as your general health and as such, sunlight exposure (without sunscreen) also plays a role in hair loss and regrowth. So let’s talk more about that now…


Sunlight and Fumaric Acid / Fumaria officinalis for Natural Hair Regrowth

Another substance that the skin produces in response to exposure to sunlight is a big secret. It’s called Fumaric Acid. Big Pharma knows all about Fumaric Acid and they’ve created synthetic Fumaric Acid Esters to treat (but not cure) multiple sclerosis, psoriasis, and other autoimmune diseases. Like all of Big Pharma’s medicines, Fumaric Acid Esters are specifically synthesized to function initially as a treatment for multiple sclerosis or psoriasis, but not as a cure. Big Pharma, after all, does not promote medicines that cure disease because conventional medicine is based on profits, not on curing disease. If you cure a disease, you lose profits. An excellent example of how dead-set Big Pharma is on covering up cures for diseases, even cures that they’ve created is the FDA-approved medicine known as Salinomycin that cures both breast cancer and malaria.  

So, it’s important that readers understand that when they go to a doctor to be treated for a disease, the doctor will only be allowed to treat the symptoms. Cures for diseases are actively covered up by Big Pharma to ensure that they’ll have repeat customers who will be willing to spend everything they have to reclaim a symptom-free life. So when we talk about fumaric acid as a cure for hair loss, we’re talking about natural fumaric acid that’s either produced in the body, produced by an herb like Fumaria officinalis, or a naturally derived fumaric acid supplement that has been isolated from a plant, but that has not been manipulated into a synthetic form in a lab. While the body naturally produces healthy, safe fumaric acid when the skin is exposed to sunlight (without sunscreen disrupting the process, that is), Big Pharma sells consumers both sunscreens (that disrupt reproductive hormone levels) to prevent consumers from receiving sunlight and to cause hormone imbalances, and then after consumers fall ill as a result, Big Pharma sells them fumaric acid ESTERS that are synthetic, and toxic and that kill cells and that cause cancer with chronic, long-term use. 


Fumaric Acid Esters cause a lot of harm to people who are already ill. But on the other hand, natural sources of fumaric acid can do a lot of good for people. Natural fumaric acid, like I mentioned above, is produced in the skin, but it is used in the liver to produce energy, which is interesting, right? Because this substance, fumaric acid, is produced in response to sunlight, but it ends up working in the darkest, most remote areas of our body: the liver. So I want to take the opportunity to talk about the fact that the liver is detoxified by sunlight. Let’s keep the discussion simple though and summarize things in this way for now: 


Sunlight exposure (without sunscreen) is detoxifying. 

Sunlight exposure (without sunscreen) is healing. 


You need to know that fumaric acid plays a vital role in the production of ATP, the energy packets that our cells use to fuel themselves, maintain health, and to stay alive. Without fumaric acid (the natural kind), your body can’t produce ATP. And if it can’t produce ATP, your cells will die and you’ll become sick. 


If you live in a location that doesn’t get a lot of sun sometimes or all of the time, consider working with a plant that produces natural fumaric acid, like Fumaria officinalis, the Earth Smoke Plant. Just like you’d expect, Fumaria officinalis is a plant that’s used to treat and cure liver disease and gallbladder problems, which are at the core of hair loss issues.


Later, on in this discussion, we’ll talk about the gallbladder-thyroid connection and how you can reclaim your health as well as your hair by taking daily doses of Lugol’s iodine. 

Often, our Amazon links to cures for diseases will mysteriously disappear after we publish. Support our outside vendors by purchasing Fumaria officinalis here.
