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.

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.

As patients, we know that the physician you choose is the most critical decision in restoring your hair is the physician you choose. Hair restoration physicians' skills, experience, and talent vary widely, as do the end results, vary widely.

You must research and choose your physician wisely. After all, who you choose will determine how natural and complete, your new hair will be for the rest of your life. The surgeons selected and approved by our community have been scouted and vetted by the forum's highly esteemed senior valued contributors of the Hair Restoration Network. Our valued contributors have all spent years researching hair transplantation, and they have all had hair transplants. To ensure there is no conflict of interest, none of our valued contributors receive any compensation. They are volunteers who have shared their experiences and contributed for years to our community. Each surgeon has been approved based on their ethics, surgical techniques, results, and reviews. To support the costs of operating and promoting our community, the approved physician contributes a monthly fee to sponsor our community.

Their recommendation is continued as long as they continue to show evidence of excellent patient results and satisfaction. If a patient expresses concerns, physicians are expected to resolve their concerns. We ask that patients first contact a physician with any concerns so that they can resolve them before publicly posting.

Note - The hair restoration physicians recommended on this site are not a definitive list of all excellent hair transplant doctors. Nor do we warrant or guarantee the results of any of the physicians presented on this site. As always, we encourage you to do your due diligence in evaluating these and all hair loss physicians.

We offer the following suggestions for researching a hair restoration physician:

• Does the physician take a holistic approach to hair restoration? Your physician should help you evaluate all your options, surgical and non-surgical.
• Have they invested time and resources in large micro follicular unit hair transplantation sessions? Outstanding work requires a staff dedicated to and trained to use high-powered magnification to produce more than 2,000 carefully trimmed grafts per surgical session.
• Choose a hair restoration clinic that is patient-focused rather than commercially focused. Some clinics emphasize revenue, speed, and volume rather than dedicating the time and individual care needed to produce optimal results. These commercial operations typically rely on heavy advertising rather than satisfied patient or doctor referrals.
• Is hair restoration the primary focus of their practice? Outstanding results require a physician and staff to perform hair restoration surgery regularly. Doing hair restoration as a sideline and other cosmetic procedures may hinder their ability to do large sessions of highly refined follicular unit transplantation.
• How many patients has this physician produced excellent results for? Like any skill, experience over time is critical to acquiring the skill and judgment required to produce excellent results.
• Can the physician provide detailed patient before and after photographs? Do they also have patients who are willing to speak with you and meet with you in person?

What do their hair transplant patients think?

Ultimately, the most critical measure of a hair transplant surgeon's work is their patient's level of satisfaction.

While Nizoral 2% shampoo is more effective at inhibiting DHT production and its binding to hair follicles, Nizoral regular strength offers a smoother, gentler approach to treating hair loss while minimizing scalp irritating effects from other topical treatments such as Rogaine 5% liquid.

This product includes 1% of the active ingredient ketoconazole. To view the clinical abstract proving the effectiveness of ketoconazole in the treatment of androgenetic alopecia, view "Ketoconazole as a hair loss treatment". Alternatively, you can obtain a prescription from your medical practitioner for the more concentrated 2%.

Developing Realistic Expectations:

Men and women sometimes suffer from hair loss for different reasons. Thus, diagnosing its cause is necessary to facilitate and promote proper treatment.

Don't expect immediate results. It's recommended to use Nizoral in conjunction with other proven treatments for at least 6 to 12 months before determining its effectiveness. Documenting your progress with bi-monthly photos can help you determine whether or not Nizoral has been successful in helping you maintain existing hair.

To date, only surgical hair restoration is proven to grow hair in completely bald areas. You are invited to have a free virtual consultation with one of our prescreened hair restoration physicians.

Most hair loss sufferers can benefit from hair transplants. However, some are better candidates than others and will achieve more dramatic results.

It is important to have realistic expectations and to find a hair transplant surgeon who can meet or exceed your expectations.

Surgical hair restoration is largely a matter of "Supply and Demand".

The look you can and will achieve with hair transplants is determined by several factors. But the most critical factor is really a question of "supply and demand".

The supply of hair is how much viable bald resistant donor hair you have. The demand is how much bald area you want to cover and to what degree of thickness.

Your “Donor Hair” determines what you can achieve.

For virtually all hair loss sufferers, even those with severe baldness, there is typically hair that grows for life on the sides and back of the head. This is because the hair in this "donor area" is genetically different from the hair on the top of the head in people who go bald.

The hair follicles in the "donor area" are genetically resistant to the effects of such baldness causing hormones as (DHT) dihydrotestosterone. That's why they continue to grow, while the hair on the top (in the male pattern baldness area) thins and goes bald over time.

How much viable donor hair you have will largely determine how much you can accomplish with hair transplants. Most people have enough viable donor hair to do at least one or two hair transplant procedures.

Revolutionary Hair Growth Formula?

Anyone suffering the effects of an incurable and debilitating medical condition yearns for the promise of new and revolutionary treatment options and hair loss sufferers are no exception. Though often dismissed as insignificant by those who are unaffected by it, baldness and thinning hair can devastate the lives of millions of men and women susceptible to the effects of androgenic alopecia. The desperation to restore the flowing locks of youth make this demographic particularly susceptible to slick marketing campaigns promising to halt balding and regrow hair. One such product marketed in this fashion is Europe’s TRX2 Molecular Hair Loss Treatment. But, will hair loss sufferers find follicles behind the flash?

TRX2 Ingredients

TRX2 Molecular Hair Loss Treatment is not a drug or medication. It is an herbal, dietary supplement taken orally. A glance at its ingredients list reveals nothing new or revolutionary. Each component is readily available at your local nutritional supplement shop, though you may not find the same concentrations of each in a single product.  It's ingredients are listed below:

Ingredients: L-carnitine tartrate (800 mg), potassium chloride (191 mg), L-leucine (150 mg), isoleucine (75 mg), valine (75 mg), nicotinic acid (40 mg), and biotin (150 µg).

TRX2 Scientific Studies?

With these ingredients so readily available, one might wonder if the significant cost savings of purchasing them individually and mixing your own TRX2 at home is just as effective for hair growth. The official website’s FAQ addresses this notion with the following response.

“The benefit of taking TRX2™ Molecular Hair Growth Supplement singularly, as opposed to buying each ingredient separately, is based on several facts:

The precise amount and ratio of ingredients in our supplement are carefully chosen and engineered based on credible scientific studies. The ingredients in our capsule were specifically formulated to work in concert with one another and are manufactured in accordance with strict European quality controls. For the consumer, the convenience of taking all compounds at the optimum ratio in one capsule and delivered via our proprietary potassium channel stimulating complex is crucially important.”

Perhaps this is true. However, at a hefty €54.95 (about $72) for a one month supply, those seeking to save some money may want to give the home brew option a shot first.

Additionally, referencing scientific studies is an effective way to add legitimacy to a product but one must always consider the source. While the TRX2 website provides detailed data gathered from a “randomized, double-blind, placebo-controlled study”, it is unclear who conducted the study and there is no mention of publication in a peer reviewed journal.  Peer review is the industry standard for evaluation of clinical trial results and its absence is cause for concern.

Does TRX2 Work?

TRX2 claims to stop hair loss and regrow hair through the “rejuvenation of potassium ion channels within hair follicles”. This theory is based on research suggesting that the opening of potassium channels is an important regulatory mechanism for hair growth.

A bold statement at the top of the TRX2 website states that it has been shown to regrow hair in nearly 9 out of 10 men and women. But, does TRX2 really do what it claims? The bottom of the company’s website provides a very important disclaimer.

“These statements have not been evaluated by the medicines regulatory agencies. This product is not a drug or medicine, and is therefore not intended to diagnose, treat, cure or prevent any disease. This patent-pending food supplement contains nutrients that help promote and sustain healthy hair growth. Results may vary and are subject to your individual metabolism. Regarding risks and side-effects please see the package insert and ask your physician or healthcare specialist.”

Careful wording in the above statement may give consumers the wrong idea. Helping to “promote and sustain healthy hair growth” is not the same as stopping hair loss or regrowing hair lost due to the effects of androgenic alopecia. A quality shampoo and condition can make hair more manageable and appear fuller.

TRX2 Side Effects

While TRX2 contains "drug-free" ingredients that are all natural or synthesized as normal metabolites in the human body, there is a potential for certain side effects.

Some consumers of TRX2 have reported transitory gastrointestinal effects including an upset stomach.  Thus, it is recommended to take TRX2 after eating.  Additional side effects include the possibility of allergic reactions such as skin flushes.  If any of these conditions occur, it is recommended to consult a physician.

 It is also recommended that any potential customers suffering from digestive system disorders, diabetes or those who are glucose-intolerant consult with their physician before taking TRX2.

Moreover, pregnant women and nursing mothers should avoid taking TRX2 due to its lack of long term safety data.

Conclusion

The role of potassium channels in hair growth is still being investigated and it’s unclear if TRX2 truly has the potential to significantly affect these channels. However, there is a clinically proven and FDA approved medical hair loss treatment that is known to do so. Rogaine (minoxidil) has been used successfully by balding men and women for more than 20 years. The exact mechanisms by which minoxidil affects hair growth are not fully understood but it is a known vasodilator and has also been shown to enhance the flow of potassium ions. Given that minoxidil is relatively inexpensive, clinically proven and comes with very little risk of side effects, it may be a better option for hair loss suffering men and women.

Additionally, balding men should seriously consider adding Propecia (finasteride) to their hair growth regimen. Propecia stops hair loss  at its core by inhibiting the production of DHT (the hormone responsible for genetic baldness) and is arguably the most effective treatment for male pattern balding currently available.

When it comes to “new and revolutionary” hair loss treatments, proceed with caution. There is nothing wrong with trying a new treatment provided it is safe and purchased from a reliable source. However, forgoing tried and true medical treatment s in favor of experimental products may result in further loss of precious and irreplaceable hair.

Stemcelex is the newest product in a long line of hair restoration therapies claiming to “cure” hair loss via stem cell therapy. Given the recent onslaught of news regarding stem cell based hair loss treatments, injectable baldness cures, and research breakthroughs, it’s not surprising to see new therapies claiming to aggressively fight hair loss through these same mechanisms. However, is Stemcelex truly a stem cell based, regenerative hair loss cure, or is it another therapy simply riding the recent wave of interest in these types of non-invasive, revolutionary treatments?

At first glance, Stemcelex seems quite impressive. The product website is filled with scientific explanations, graphs, charts, and diagrams explaining the science behind stem cell based hair restoration. Stemcelex even states its affiliation with Dr. George Cotsarelis, a researcher at the University of Pennsylvania Medical Center who, along with a talented research team, recently discovered that the bald scalp does not suffer from a lack of stem cells, but rather a dysfunction in the pathway to properly activating stem cells to produce hair. The finding was significant and Dr. Cotsarelis’ involvement and the seemingly detailed science look promising, but what about Stemcelex itself? Does it utilize these scientific breakthroughs and offer an effective treatment for hair loss?

Unfortunately, despite the impressive name recognition and detailed explanations, Stemcelex doesn’t appear to live up to its lofty hair restoration claims. Despite claiming to “activate” the dormant stem cells described by Dr. Cotsarelis, Stemcelex does not offer any sort of feasible molecular/stem cell based therapy. The website cleverly explains the science behind stem cell inactivation and the promise of reversing the dysfunctional pathway, but instead of reinforcing Dr. Cotsarelis’ view that cures for reversing the inactivation pathway are not yet understood, Stemcelex claims to actually fix the stem cell inactivation through a series of unproven homeopathic and herbal treatments for hair loss.

So, what is actually inStemcelex? The treatment involves a three day cycle of different lotions and topical treatments for baldness applied twice a day.

Day1: On the first day of the hair restoration cycle, a topical lotion made from Jaborandi Pilocarpus is applied twice after washing and thoroughly drying one’s hair. According to Stemcelex, Jaborandi Pilocarpus is a parasympathetic activator (it excites the nerves that cause the body to “rest and digest” during periods of relaxation) that rids the scalp of excess oils and dandruff that impede healthy follicular hair growth. Furthermore, Stemcelex claims that Pilocarpus naturally darkens and thickens existing, native hairs. According to the experts, Pilocarpus has no reproducible pharmacological applications and any evidence that it actually thickens and darkens hair is anecdotal.

Day 2: The second day of the cycle involves Veratrum Lobelianum, a family of herbs commonly used in Chinese medicine.  Stemcelex claims these herbs can penetrate the scalp and activate the necessary molecular signaling to “regenerate” the hair follicle stem cells. Furthermore, Veratrum allegedly down-regulates or prevents the production of Dihydrotestosterone (DHT), the hormone directly responsible for male pattern baldness. According to the research, members of the Veratrum family have been used in everything from a Native American poison to a drug researched in human blood pressure.  Currently, they are used in cancer treatments. Although the science behind cancer therapies indicates that the drug could have some molecular benefit in signaling cell activation and inactivation, there has been no research or evidence suggesting that Veratrum is useful in fighting, reversing, or preventing the effects of male or female hair loss.

Day 3: During the third day of the Stemcelex cycle, a kelp based topical extract is applied twice daily to provide nutrients to the “new hair growth” and also ensure that the scalp remains clean and healthy. This step of the treatment doesn’t claim to be more than a simple dose of nutrients useful in good scalp hygiene.

After reviewing the active ingredients behind Stemcelex, there is no evidence to suggest that Stemcelex is an effective hair loss treatment at this point in time. The idea of activating the dormant stem cells is important to finding a molecular cure to hair loss, but despite understanding this importance, Stemcelex doesn’t offer any concrete stem cell reactivation agents. It’s possible that Veratrum may prove useful in cell signaling and reactivating dormant cells, but the current research and evidence simply don’t support its use at this time.  Furthermore, Stemcelex charges a hefty $99.85 for a month supply of the treatment which may keep even the most curious and enthusiastic hair loss suffering men and women away.

Altogether, the idea of reversing dormant hair follicle stem cells is important, but therapies for effectively stopping and rewiring this pathway do not seem to exist at this point in time. Unfortunately, this seems to nullify the claims made by Stemcelex and prevent it from becoming a stem cell hair loss cure.
