Psoralea corylifolia is a natural source of NATURAL psoralen that can be used to treat hair loss at home in combination with 15 minutes daily of sunlight exposure (sans the sunscreen).

PUVA Hair Loss Treatment in Conventional Medicine: A Critical Discussion

Disclaimer: Consult with a doctor before deciding on a treatment plan for any disease.

Doctors have recently begun using a combination of psoralen and ultraviolet-A light exposure to treat hair loss. This phototherapy treatment, PUVA, is a conventional medicine therapy that has been used on psoriasis patients for quite some time, despite the fact that there are natural cures for psoriasis that offer a very high success rate. But when we stumbled across the scientific literature on the use of PUVA for hair loss in conventional medicine and its effectiveness in some cases of alopecia, we were excited about it, because it shows that there’s a relationship between certain types of hair loss and psoriasis. To be clear, I’m not advocating that anyone use PUVA therapy for hair loss or for any other type of disease, but rather, I want to use PUVA research for hair loss and for psoriasis to explain the theory behind sunlight exposure (without sunscreen) as a natural hair regrowth treatment.  Because we’ve been able to find simple, effective and natural psoriasis cures in the scientific literature that we’ve detailed in our book The Psoriasis Cure, we believe that there are simple, effective and natural cures for hair loss as well. Indeed, people who are struggling with hair loss should consider reading this book and working with psoriasis cures as a part of their treatment protocol because psoriasis and hair loss are health problems that are intimately related.

Psoralen as a Treatment for Hair Loss: What You Need to Know

Psoralen is a naturally-occurring chemical in a number of plants including:


  • Psoralea corylifolia
  • Daucus carota (carrots)
  • Ammi visnaga
  • Pastinaca sativa
  • Levisticum officinale
  • Foeniculum vulgare
  • Ficus carica
  • Celery
  • Parsley
  • West Indian Satinwood
  • All citrus fruits
  • Bergamot Essential Oil

Psoralen is photo-reactive. This means that when you take psoralen as a SYNTHETIC prescription drug or if you consume a plant-product containing NATURAL psoralen, your body will become more reactive to sunlight. Indeed, SYNTHETIC psoralen was once used as a tanning accelerator before the long-term side effects the drug became apparent (see below). It’s important at this juncture to note that SYNTHETIC psoralen and NATURAL psoralen are chemically different. The prescription psoralens that were synthesized in a lab by Big Pharma are listed below. They are much more toxic than the natural psoralens that are in plants:

  • Uvadex / Methoxsalen
  • Oxsoralen-Ultra / Methoxsalen
  • 8-MOP / Methoxsalen

The natural psoralens found in plants exist in balance with a wide array of other substances that work with the psoralens to produce medicinal effects in the body. In other words, the effects of psoralens in plants are balanced by the effects of all the other components of the plant. 

Synthetic psoralens, in contrast, are chemically isolated from plants by lab workers, and then they’re changed slightly in a lab so that they can be patented (naturally occurring things cannot be patented, after all). This is why synthetic, prescription psoralens are so dangerous. Think about it. In order for a natural substance like psoralen to be patented, it must be changed into something unnatural that is not found in nature. Though at first, many synthetic medicines seem to work, within a short period of time, their toxicity starts to become apparent to patients and they develop new symptoms of disease. Doctors often make new diagnoses of new diseases and then prescribe new medicines when this happens (which is extremely profitable, of course, for Big Pharma). The plants and herbs listed above, in contrast, contain substances like psoralens in balance with other substances that work in synchrony in the body. The plants are natural and the psoralens they contain are natural, so not only are they less toxic, they are also less expensive.

We’ll talk about the use of natural, herbal psoralen as a treatment for hair loss below.

Is PUVA treatment safe as a hair loss treatment?

In conventional medicine, PUVA treatment is considered to be one of the most effective treatments for psoriasis. It won’t cure the disease by design, but PUVA is relatively effective nonetheless. Why? Because sunlight, fumaric acid, and bile supplements can be used to cure psoriasis in people who choose to seek out natural cures. All of these natural treatments are sun-derived and sun-influenced treatments that exist in nature. In other words, PUVA is an unnatural hair loss treatment that capitalizes on the fact that the body needs natural sunlight exposure which causes the production of natural fumaric acid in the skin and that naturally boosts liver health and bile production. PUVA does not involve the administration of the full-spectrum light of the sun and so, while it works to boost hair growth, it does not promote overall health. PUVA treatment involves only Ultra-Violet A (UVA) administration so patients who receive this treatment, still don’t get red light, infra-red light, or the other healing light wavelengths that cause natural fumaric acid production that would cure hair loss and psoriasis and the underlying disease processes that cause these problems in the first place. So patients have to continue to go in and get PUVA treatments, which is costly, inconvenient, and TOXIC to their health. 

PUVA treatment involves scientifically documented, serious long-term side effects including:

  • Chronic degeneration of the skin
  • Pigmentation changes to the skin
  • Non-melanoma skin cancers
  • Squamous cells carcinomas

PUVA Treatment for Hair Loss vs. Natural Treatments for Hair Loss

The so-called “effectiveness” of PUVA, a toxic treatment (by design) when it is administered by conventional medicine doctors points to the actual, natural cures for hair loss and psoriasis, namely sun exposure, natural fumaric acid production in the skin and liver via sunlight exposure, and the natural production of bile, a substance that not only ensures that our bodies can digest fat-soluble vitamins including vitamin A, D, E, K1, and K2, but that also functions like a natural detergent in our digestive system. Indeed, bile is also a substance that functions to balance cholesterol levels as well as reproductive hormone levels. 

Though hair loss and psoriasis may not, at first appear to have anything in common except the fact that both involve problems with the skin, the reality is that hair loss, in most cases, is a problem involving nutrient deficiencies, lack of sunlight exposure (without sunscreen) and all of the corresponding problems that spiral outward from these two root causes. Some people with hair loss will need to work with other natural hair loss treatments like inositol supplementation, essential oils and DMSO, or thymus peptides and extracts, but sunlight exposure without sunscreen, fumaric acid supplementation, and enzyme therapy is a good place to start if you’re ready to work with natural medicines for hair regrowth.  

The good news is that PUVA for hair loss is said to work fairly well in conventional medicine settings. Let me explain why this is good news. Conventional medicine is profit-centric and not cure-centric (indeed, our material at AlivenHealthy is often censored on Google and Facebook because we dare to even use the word “cure” to describe medicines and treatments), so if you go to a doctor for hair loss treatment, you’ll likely end up on a chemotherapy medicine that will cause serious side effects and that will lead you toward a much more serious diagnosis in the future that will be much more profitable for Big Pharma. Your doctor may also prescribe PUVA light treatments that will eventually cause you to develop skin cancer and your hair loss will probably continue to occur in a cycle of relapses and remissions over time.

But PUVA treatments for hair loss point to the fact that hair loss is caused, at least to some extent, by a lack of sunlight and the cascade of problems that result from not being exposed to enough sunlight each day. Indeed, many people in developed countries today wear sunscreen to protect themselves from the sun without realizing how sunscreen would contribute to problems like hair loss due to reproductive hormone imbalances that they cause (because most of the main ingredients in sunscreen are endocrine disruptors). Most people in the world today believe that sunscreen is good for them and that sunlight is bad for them. In contrast, practically no one in the world today knows that sunlight exposure causes fumaric acid production in the skin and that fumaric acid is used by the liver to produce ATP, the main energy source for our cells. In other words, if you don’t expose yourself to sunlight (without sunscreen), your cells will start to die. Hair cells and follicles are often first in line to be neglected as the body tries to re-allocate energy resources that are lacking due to not having enough fumaric acid. The effectiveness of PUVA treatment in conventional medicine provides clues to the fact that people with hair loss need more sunlight and more fumaric acid. 

Funding to prove that sunlight is good, that sunscreen is bad, and that you could take a natural, herbal psoralen and expose yourself to a little bit of sunlight each day that would have far less toxic, and far more medicinal effects on the body than PUVA simply isn’t available. Funding for research into medicines comes from Big Pharma and Big Pharma supporters, after all. So there’s very little research into natural cures for disease. But there’s enough research and there are enough anecdotal reports, thankfully, to piece together the puzzle of hair loss and how to regrow hair. If your doctor has suggested that you do PUVA as a hair loss treatment, consider spending some time in the full-spectrum light of the sun instead and see if that helps. Or take natural fumaric acid supplements (NOT synthetic fumaric acid esters, which are similarly toxic like synthetic psoralens) either as pure fumaric acid or in an herb like Fumaria officinalis. Note that often, people who have not had a lot of light from the sun will experience an initial Herxheimer Reaction from sunlight exposure

And finally, if you’re truly afraid of getting rid of your sunscreen, consider using Burmese Thanaka as a natural sunscreen alternative. Thanaka is derived from trees and it has protected the Burmese people from the harsh, hot sun for centuries.
