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.

Diffuse Hair Loss and How to Treat It

Unlike male pattern baldness (MPB) and female pattern hair loss (FPHL), which tends to follow one of the hair loss patterns defined by the NorwoodScale and the LudwigScale, Diffuse Patterned Alopecia (DPA) is characterized by diffuse thinning throughout the front, crown and vertex(crown) with no distinct pattern evident. However, like male and female pattern balding,Diffuse Patterned Alopecia patients typically preserve the stable "permanent zone" on the sides and back of the scalp and may sometimes retain a well-defined hairline. DPA is also a type of hereditary balding condition like and rogenetic alopecia (genetic hair loss).

Diffuse Patterned Alopecia (DPA) can be difficult to diagnose and, particularly in its early stages, may be confused with a similar condition known as Diffused Unpatterned Alopecia (DUPA). While both conditions are characterized by diffuse thinning, DUPA sufferers lack the stable permanent zone necessary for surgical hair restoration.

Treatment for Diffuse Patterned Alopecia

DPA often responds well to medical hair loss treatments like Propecia (finasteride) and Rogaine(minoxidil) and, due to the preservation of the permanent donor region, many DPA sufferers are candidates for hairrestoration surgery.

Conclusion

It’s essential that hair loss suffering men and women seeking medical and/or surgical treatment for diffuse thinning consult with a skilled and experienced hair restoration physician. Differentiating between DPA and DUPA is critical because Diffuse Patterned Alopecia patients frequently make good hair transplant candidates, whereas DUPA patients rarely do.

Contained in Several Popular Hair Loss Treatments for Men

Nettle root extract can be found in a number of popular hair loss treatments, such as Provillus and Procerin, and at your local health food store as a standalone product. Conjectured to effectively inhibit the production of DHT, below we examine whether or not nettles are as effective as Propecia (finasteride) in blocking DHT and stopping the progression of male or female pattern hair loss.

Description

“Nettles” is the common name for Urtica Dioica, an herbal plant also known as the Stinging Nettle. This perennial herb is often eaten in many parts of the world and is often added to soups, salads or cooked as greens, though less frequently. Nettle leaves are long and pointy, but only the shoots and top of the plant are eaten. Nettle plants have dark green leaves and typically grow about 2 or 3 feet tall and its flowers are covered with tiny stinging hairs that contain an irritant. Allergic reactions are common if they come in contact with human skin.

Use of Nettles

Nettle root extract was found to partially block 2 enzymes by researchers such as R. Hartmann.  The first is 5-alpha-reductase that when combined with testosterone, produces DHT (dihydrotestosterone). DHT is the hormone responsible for androgenic alopecia hair loss. The second enzyme is aromatase, which makes estrogen.  Combining nettle root extract with another herbal agent pygeum has been found to inhibit these two enzymes more effectively than either one alon It was shown that nettle root extract had to be used at high dosages in order to effective whereas lower doses of pygeum worked well.  Prostatonin, the combination product of nettles and pygeum have been used to treat BPH (benign prostatic hypertrophy).

Studies by researchers JJ Lichius and others have shown a reduction in prostate growth in mice when large doses of nettle extract were taken orally. Combining nettle root extracts with saw palmetto berries in BPH patients reduced the amount of testosterone and estrogen. Conversely, it has been conjectured that nettles can block testosterone from binding to the sex hormone globulin, a carrier protein that binds testosterone and limits its bioavailability in the body. As a result, nettles have been called an aphrodisiac since it may help maintain testosterone levels.

Other uses of Nettles include treatment for arthritis, asthma, kidney, urinary tract infections, and last but not least, baldness.

Nettle Root as a Hair Loss Treatment

Like many other herbal supplements with some clinical evidence suggesting efficacy in treating enlarged prostates (BPH), some have claimed that nettle root extract may stop hair loss and maybe even aid hair regrowth.  Because Propecia (finasteride) works to stop the progression of male pattern baldness by inhibiting the production of DHT, it is conjectured that nettle root extract may be of similar benefit.

Nettle root is a popular ingredient taken orally in a couple big name hair loss products such as Provillus and Procerin.  Some have also conjectured that applying nettle root extract topically to the scalp may also facilitate new hair growth. Because many topical irritant type products are used to treat alopecia areata hair loss, some suggest nettle root extract applied topically may be effective in treating it. Those who conjecture its efficacy to treat baldness recommend doses of 500mg or more daily.

Though some have declared that nettle root extract may be an effective hair loss treatment, no clinical controlled studies have been performed proving its efficacy for androgenic alopecia (genetic female hair loss and male pattern baldness) or alopecia areata. 

Possible Side Effects of Nettles

Despite claims made that “all natural” herbal supplements are free from side effects, nettle root has its share of warnings. When topically applied, irritation of the scalp or an allergic reaction can occur. When taken orally, it can cause upset stomach, burning, difficulty with urination, bloating and edema.  Nettle root extract should not be used in patients with heart or kidney problems, due to fluid retention properties.
Those who want to try nettle root extract as a hair loss treatment should proceed with caution and consult their doctor before using it.

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.

Many cases of female hair lossare caused by hormonal fluctuations or changes in the body including those who have PCOS (polycystic ovarian syndrome), birth control pillside effects, a recent pregnancy,postmenopausal trauma, or menopause. Women with hair loss experience varying balding patterns These patterns can help determine the type of alopecia you have along with a thorough examination by a physician.

Because of an imbalance between estrogen and testosterone due to declining estrogen levels, thinning hair and accelerated hair loss is common in women during menopause. Hair on certain areas of the head that is more sensitive to androgen hormones like DHT(associated with male pattern baldness) may thin or fall out. Similarly, declining estrogen levels may result in unwanted facial hair growth.

In some cases, polycystic ovarian syndrome(PCOS), may accompany menopause and hair loss.

Be sure to speak with your doctor on the most effective ways to cope with menopause and minimize hair loss during this transitional time.

One product you used to see quite often in advertising is Avacor. According to Response magazine, Avacor was the third best selling product on the Internet in April, 2002. Avacor was originally manufactured by Global Vision Products. After being taken over by new management, it is now being manufactured by Avacor Products LLC.

Like most products that advertise 'Stop Hair Loss and Regrow Hair!', Avacor contains the only FDA approved topical drug minoxidil. Avacor, like other products with similar claims, mixes FDA approved drugs in their generic form with other ingredients in a multiple regimen of products like shampoo, lotion and vitamins.

Avacor historically cost approximately $239 for a two to three month supply and over $1000 for a year’s worth.  New prices are much more reasonable which range from $180 for a 3 month supply to $400 for a year’s supply of the men’s and women’s formula. Note that the ingredients in Avacor can be bought over the counter at your local store at a fraction of the cost for which they are sold in Avacor. However, they do offer 24/7 customer service and a 90 day money back guarantee.

Marketing Practices

Avacor, like other products with similar claims, has taken a lot of slack over the years for their controversial marketing tactics. Avacor has a checkered past and has previously been the focus of lawsuits and investigative reporting by major media like ABC news. Recently however, new management has taken over and claims they are very serious about selling quality products at more reasonable prices, without the hype and controversial marketing strategies. In looking at their website, while Avacor still uses slick marketing language to promote their products, the vast majority of their claims are much more realistic.

Avacor includes 3 distinct products that claim to provide “total hair care”. This includes a 'Scalp Detoxifying Shampoo', a 'Physicians Topical Formulation' and finally a 'Nutricap'. Avacor's Nutricap ingredients consist mainly of common herbs like saw palmetto, gingko biloba, keratin, resveratrol, and bilberry. While conjectured to inhibit the production of DHT, none of these ingredients are FDA approved or proven to stop hair loss. Avacor’s Physician’s Topical Formulation however, does contain 5% of the FDA approved hair regrowth agent minoxidil.

Other than minoxidil, no other ingredient is proven to regrow hair. A number of studies have been done that suggest saw palmetto inhibits the production of DHT, like Propecia. But, unlike Propecia, it has never been proven to stop or reverse hair loss.

Avacor Products

Avacor admits on their website that the only product proven to regrow hair is the Avacor Physician’s formulation which includes the FDA approved ingredient minoxidil (5% for men and 2% for women). The other products claim to provide hair with the essential nutrients for healthy hair growth but are careful not to claim to prevent the progression of male or female pattern baldness (androgenic alopecia). Perhaps this is why the Avacor Physician’s formulation can now be purchased separately. Costs of the Physician’s Formulation are still, but only a little more expensive than Rogaine topical hair loss treatment, one of the first and most popular topical minoxidil products.

The Avacor Study

At this time, Avacor’s proof comes in the form of the FDA approved study showing that minoxidil can stop and reverse hair loss.  No other study is provided with their product.  Their website also is much more realistic as to what their product line can accomplish for hair loss suffering consumers.

Confidence in Products and Services

Before you consider spending hundreds of dollars for any product or service, do a review. Legitimate products will have legitimate studies and have been reviewed on many quality websites. Doctors with real talent and satisfied patients will be able to show you dozens of photos and allow you to talk with past patients. Proven physicians will make available their resumes along with their formal education and associations they belong to.

It is always best to review a product or doctor for information on their background before you make a decision for something as important as hair loss and hair restoration.

Conclusion

At the very least, the Avacor Physician’s formulation will be as effective as the Rogaine liquid formula or generic minoxidil. However, to date, both Rogaine and generic minoxidil are more cost effective than Avacor.  The nutricap, shampoo, conditioner and other products may promote healthy hair and provide it with volume, but make no claims of stopping hair loss or regrowing hair.
