Para-Aminobenzoic Acid (PABA) has been called the anti-gray hair vitamin and is considered one of the lesser known members of the vitamin B complex family (despite the fact that it’s not really a vitamin at all).  PABA is a non-protein amino acid and isn’t essential in the human body.  It can be found in foods such as liver, whole grain, yeast, and kidney and is listed as an active ingredient in several popular herbal hair loss treatments such as Provillusfor women and Procerin. 

The potassium salt in PABA called POTABA is available on prescription. POTABA is indicated for Peyronie’s Disease and scleroderma. The dose for Peyronie’s disease and scleroderma is very high (12 grams daily in 4 to 5 distributions) and must only be used under medical supervision. Because of the high doses needed to achieve clinical efficacy, patient compliance is typically poor.

But can PABA actually treat male pattern baldnessor genetic female hair loss?

Some tests conclude that PABA when combined with other elements such as folate, biotin, and pantothenic acid, may restore pre-maturely graying hair to its natural color.  Some anecdotal reports suggest it might also stop hair loss, however; there are at least as many reports that contradict this.  Moreover, we haven’t seen any evidence to suggest it can stimulate new hair growth or hair regrowth.

PABA comes in doses of 100mg, 250mg, and 500mg as a standalone product.  However, since no formal clinical studies have been performed on PABA for hair loss, a suitable dosage is mostly speculation.  Additionally, since no regulations have been placed on herbal medication, one should proceed with extreme caution before taking any herbal supplement.  Consulting with a doctor is advised.

Side Effects and warnings:

Some manufacturers of herbal replacements to medication would have you believe that herbal treatments come without potential side effects.  However, this is a farce. 

The following side effects have been reported from consumers of PABA: Anorexia, vomiting, nausea, hypersensitivity, fever and rash (particularly with larger doses). These symptoms went away when PABA is stopped.

Ironically, Provillusonly includes PABA in the woman’s formula.  However, women should know that pregnant women, nursing mothers, and children should avoid using PABA.

For those with renal disease, PABA should be used with caution.  PABA should be stopped if hypersensitivity develops. Those taking pharmaceutical doses of PABA must be under medical supervision.

This hair loss product is a 5% custom solution that combines Minoxidil with Azelaic Acid. Developed by Dr. Richard Lee, a hair loss physician, it’s available by prescription only.

Xandrox’s two main ingredients tackle hair loss in two ways. The minoxidil stimulates hair growth, while the Azelaic Acid, which contains the 5 Alpha Reductase enzyme, blocks DHT. However, while minoxidil is a proven hair loss treatment, Azelaic Acid is only proven as an acne medication. Many patients feel that Xandrox is preferable to Rogaine because it’s less greasy.

As of yet, Xandrox has shown few side effects, and may cause less itching and flaking than Rogaine.

There may be some burning irritation though, due to the Azelaic Acid. But one type of Xandrox counteracts this side effect. It contains a Betamethasone Valerate, a corticosteroid.

However, you need to know that corticosteroids may cause problems. Short-term use is pretty safe, but if used long-term, they may cause thinning of the skin or skin damage. It may also lead to brittle bones or diabetes. For this reason, it’s recommended that if you have no itching problems that you should use the Betamethasone-free Xandrox. It is available, and it works as well as regular Xandrox.

There are other types of Xandrox, including the Day Formula, the Night Formula, and Xandrox 12.5%, a cream that’s used for more stubborn areas, such as the frontal hair line, and contains 12.5% Minoxidil. One ml of Xandrox should be applied twice per day, and a routine should be established.

A Viable Alternative to Propecia in Treating Hair Loss?

Folexen S-equol , produced by Australian manufacturer Eclipse Nutraceuticals is considered an "all natural" hair loss treatment that boasts an impressive 87% success rate for preventing and reversing the effects of male pattern baldness with virtually no side effects.  Folexen S-equol has also been a hot topic of discussion on our popular hair loss forum. But, does this self-described "nutraceutical" live up to its hair growth hype?  Is Folexen a viable alternative to Propecia for treating the effects of male pattern baldness?

What is Folexen S-equol?

According to the FAQ on Folexen's website, the active ingredient S-equol is "a metabolite of a natural isoflavone called daidzein, which occurs in soybeans and some other food products".

Isoflavones are an organic compound produced almost exclusively by various bean types. In populations that consume large quantities of soy protein, studies have shown a lower incidence of breast cancer and other common cancers because of its role in influencing sex hormone metabolism and biological activity.

As a metabolite, S-equol is the product that remains after the isoflavone is broken down or "metabolized" by the body.

In addition to its active ingredient, Folexen contains the following GRAS (generally recognized as safe) inactive ingredients: starch, maltodextrin, allantoin, propionic acid. It may also contain hypromellose (vegetarian capsule).

But is there any evidence that S-equol  works to treat hair loss?

How Folexen S-equol Allegedly Works to Treat Baldness

In the body, testosterone is converted to the hormone dihydrotestosterone (DHT) via the enzyme 5-alpha-reductase (5AR). It's widely known that androgenic alopecia (genetic hair loss) results when genetically vulnerable hair follicles are exposed to DHT which then binds to the receptor sites of these follicles causing them to weaken and shrink over time. This shrinking process is known as miniaturization.

The recognized leader in the battle against the balding effects of DHT is the clinically proven and FDA approved drug Propecia (finasteride). Propecia works by inhibiting the conversion of testosterone to DHT, potentially slowing or even reversing the effects of androgenic alopecia. However, approximately 2% of males who take Propecia experience debilitating sexual side effects.

Unlike finasteride, Folexen's rumored ability to suppress hair loss and potentially regrow hair is based on the theory that S-equol can bind strongly to free DHT molecules, prohibiting them from binding to the hair follicles' receptor sites. Because Folexen does not suppress the conversion of testosterone to DHT, there is no resulting increase of testosterone in the body and therefore, no sexual side effects. But are there any clinical studies supporting that S-equol can truly prevent DHT from binding to hair follicle receptor sites and prevent hair loss?

Clinical Studies

Folexen's website references four articles in peer reviewed journals. Two of these studies center on S-equol's effect on prostate health while the other two don't appear to reference S-equol at all.

At this time, there appears to be no scientific data presented supporting Folexen's efficacy as a hair loss treatment.

Side Effects

The company claims that the product is virtually side effect free: specifically noting that it does not cause gynecomastia (enlarged breasts), erectile dysfunction or any of the other side effects that are experienced with some other treatments.

Some users however, did report mild diarrhea that dissipated within one week of commencing treatment.

What is the Recommended Dosage?

The recommended dosage of Folexen is 4 capsules per day (two every 12 hours), totaling 10mg of the active ingredient. Eclipse claims that the product has been tested safe at much higher concentrations (up to hundreds of milligrams) and there is some speculation based on available data that it may, in fact, require a dose as high as 100mg to match the Propecia's hair growth results.

Where to Buy Folexen S-equol

Folexen is only available by mail order from Australia. A bottle of 100 2.5mg capsules (25 day supply) costs approximately $40 USD + shipping but there is a discount for purchases exceeding 4 bottles and again for 9+ bottles. However, it's easy to see that even in bulk this treatment is several times more expensive than purchasing generic 5mg finasteride and quartering the tablet, as many finasteride users do.

As a natural product and not a drug, there are no shipping restrictions. Estimated delivery time is two weeks.

Conclusion

Time will tell if Folexen S-equol proves to be an effective weapon in the fight against androgenic alopecia or simply another product in a long line of expensive disappointments.

What Is DUPA?

Diffuse Unpatterned Alopecia (DUPA) is a form of genetic hair loss characterized by diffuse thinning over the entire scalp. Unlike Diffuse Patterned Alopecia (DPA), DUPA lacks the stable permanent zone associated with other forms of alopecia.

Dr. O'tar Norwood defined DUPA in his 1975 seminole publication "Male Pattern Baldness: Classification and Incidence" as:

Diffuse, Unpatterened Alopecia (DUPA). In this type, there is a general decrease in the density of hair without any definite pattern, although it is usually more marked over the top and front. This type is common in women.

Identifying DUPA

Diffuse Unpatterned Alopecia patients have a similar pattern of hair loss to DPA patients but the balding tends to occur more rapidly. DUPA patients are also more likely to achieve the “horseshoe” pattern commonly associated with Norwood class VII baldness. However, unlike other forms of alopecia hair loss, the DUPA “horseshoe” takes on a thin and transparent appearance.

It is important that patients suffering from diffuse hair loss are properly diagnosed. While DPA patients are often good candidates for surgical hair restoration, DUPA patients typically make poor hair transplant patients due to the lack of a stable zone in which to harvest donor grafts.

Treatment for Diffuse Unpatterned Alopecia

Not a lot is known about the cause and treatment of DUPA. However, about half of males who suffer from this form of balding benefit from Propecia (finasteride). Unfortunately, DUPA is about 10 times more common in females for whom Propecia is not a treatment option.

Conclusion

Anyone suffering from diffuse hair loss should consult with a dermatologist or hair restoration physician for a proper diagnosis. This is especially true for balding men and women considering hair transplant surgery.

It was Hippocrates, the “Father of Modern Medicine”, who first recognized a connection between hair loss and the sexual organs. Hippocrates’ studies of eunuchs (men castrated before puberty) observed that these men did not suffer from hair loss.

We know today that this is due to the absence of testosterone, which is normally converted into dyhydrotestosterone or DHT – the active ingredient in baldness. In March 1995, Duke University researchers came to the conclusion that " . . . while castration may be a cure, it is not commercially acceptable."

Hippocrates had a personal interest in finding a cure for baldness as he suffered from hair loss. He developed a number of different treatments including a mixture of horseradish, cumin, pigeon droppings, and nettles to the scalp. This and other treatments failed to work and he lost the rest of his hair. The area of permanent hair on the back and sides of the head (from which donor hair is taken for hair transplants) is also known as the “Hippocratic wreath.”

Ancient Rome and Hair Loss

Moving from Greece to the Roman Empire, we find that Julius Caesar employed a variety of methods to hide his thinning hair. In addition to the laurel wreath that he wore, he first grew his hair long in the back, and then combed it forward over his bald spot. Yes, the “Comb Over” is ancient.

Being a Eunuch – the sure way to stop baldness

In the 1940’s, the studies of Hippocrates and Aristotle were continued. Both men had concluded that eunuchs always kept all their hair.

This finding was backed up by the work of Dr. James Hamilton.

He discovered that certain male hormones (missing in eunuchs) were critical to the development of male pattern baldness.
