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.

The "Active" Ingredient in Many Popular Hair Loss Treatment Products

Many popular hair loss treatment options today such as Provillus, Procerin, and Avacor contain the “active” ingredient saw palmetto. It can also be purchased as a standalone supplement in most nutritional stores. But the age old question of whether or not it can effectively treat baldness in men and women with alopecia is still heavily debated. By taking a look at the scientific evidence available we are able to draw some conclusions as to its potential benefit for those with thinning hair.

What is Saw Palmetto?

Saw Palmetto berries are a deep red fruit that grow wild on palm trees in warmer climates, typically found in the Southeastern United States. The liposerolic berry extract is typically used as an herbal supplement for the promotion of a healthy prostate.

Saw Palmetto Hair Loss Study:

Similarly to finasteride (the active ingredient in Propecia and Proscar), studies have shown that when taken orally, it may be an effective anti-androgen by lowering dihydrotestosterone (DHT) levels in the body by blocking 5 alpha-reductase enzymes. Additionally it is said to block receptor cites on cells which is required for cells to absorb DHT.

Tests have also been performed on its use in the treatment of benign prostatic disease, which similarly to androgenic alopecia, depends on the production of DHT.

It is also noteworthy to state that a small preliminary study in 2002 was performed as reported by The Journal of Alternative and Complementary Medicine(2002;8:143-52) that shows a select group of 19 men between the ages of 23 and 64 taking either (400mg of saw palmetto and 100mg of Beta-sitosterol) or a placebo orally. Those who took the herbal combination had 60% improved hair growth over those who took the placebo. There have been no studies to date indicating the efficacy of saw palmetto applied topically for male pattern baldness, female hair loss, or anything to date.

In our opinion, there are two potential difficulties with this study:

• Many scientists would argue that the control study group was too small to determine any real efficacy and improved hair growth could have happened by chance. A larger study therefore may be necessary to determine any level of real efficacy.
• “Improved hair growth” is not the same thing as newhair growth and hair regrowth, nor should it necessarily imply that it works to stop hair loss
• There are no regulations or suggested daily value as to how much saw palmetto would be required to successfully treat baldness. The appropriate dosage therefore is questionable.
• The above study was only performed on saw palmetto taken orally. Hair loss products that promote topical use for baldness are basing their belief in its efficacy on something other than published clinical evidence.

The Dosage:

But if there are no current standards on dosages of herbal medications in the United States, how do these popular hair loss treatments produce an appropriate dosage?

Clinical studies on Benign Prostrate Hyperplasia (BPH) have used a dosage of 320mg of the berry extract daily (either one 320mg pill or 2 X 160 mg pill). A daily dosage of 480 mg of saw palmetto berry extract was not found to be any more effective in a six-month study. If the entire berry was used, up to 1000mg or 2000mg would be required to reach the same goal.

The theory therefore is that if saw palmetto can successfully treat an enlarged prostate similarly to finasteride, it can effectively treat hair loss with a similar dosage Many popular “baldness cure” products contain approximately 1500mg of the berry which is equivalent to approximately 240-320mg of the berry extract.

Side Effects and Warnings:

One false assumption is that “all natural” treatments don’t have potential side effects. It is stated that use of saw palmetto has not proven to be safe for women with hair loss during pregnancy and lactation. Medical supervision is suggested for women of childbearing age. Similar warnings are listed about Propecia.

Conclusions:

Based on some anecdotal evidence, saw palmetto is said to treat baldness because of its tendency to act like finasteride by helping those suffering from BPH. However, authentic clinical studies have not been performed to date that support this claim. Dosage and how it should be used (orally or topically) therefore is based on conjecture rather that scientific evidence.

Birth control pills can be a great way of preventing conception however;all medication comes with potential side effects. In addition to the many serious possible side effects associated with birth control pills, some come with a risk of female hair loss. By suppressing ovulation due to the combined actions of hormones progestin or estrogen, women who are predisposed to hormonal related hair loss may experience varying degrees of balding while on the pill, or even more likely, a few weeks to months after coming off of it.

Yasmin is a birth control pill that combine sethinyl estradiol and drospirenone Because Yasmin may induce hair follicles into the telogen phase (hair shedding) of the hair growth cycle, hair loss is a reported side effect

We recommend women to use only low-androgenindex birth control pills. For women with a strong predisposition for genetic hair lossin their family, we recommend use of other non-hormonal birth control pills or other forms of contraceptives for the prevention of conception.

For your reference, here is a list of birth control pills ranging from the lowest androgen index to the highest: Desogen,Ortho-Cept, Ortho-Cyclen, Ortho Tri-Cyclen, Micronor, Nor-Q D, Ovcon-35,Brevicon/Modicon, Ortho Norvum 7/7/7, Ortho Novum 10-11, Tri-Norinyl, Norinyland Ortho 1/35, Demulen 1/35, Triphasil/Tri-Levien, Nordette, Lo/Ovral,Ovrette, Ovral, Loestrin1/20, Loestrin 1.5/30.

Over the past several years surgeons have used various techniques to perform follicular unit hair transplantation. One such technique is the Lateral Slit Technique, also known as Coronal or Perpendicular Grafting. This technique’s name is derived from the angle and direction in which the graft incisions are made.

While there are other techniques for performing densely packed and highly refined follicular unit transplantation, the lateral slit technique offers a high degree of control over the angle and direction in which the transplanted hairs will ultimately grow.

The lateral slit technique has been used both intuitively and systematically for years by hair restoration physicians. However, it has recently gained popularity as a systematic and precise way of performing follicular unit hair transplantation.

How our member physicians use the Lateral Slit Technique.

Many of our physician members use the Lateral Slit Technique exclusively or in combination with other techniques for creating graft incisions. The lateral slit technique enables a surgeon to create graft incisions at varying angles (ranging from 10 to 90 degrees to the scalp), including very acute angles that will make the transplanted hair grow out lying flatter to the scalp. The ability to create incisions at very acute angles is particularly useful in areas such as the front temples and sides where the hair normally grows out lying flat on the scalp.

The graft incision determines the direction of the hair growth

The lateral slit technique also helps enable a surgeon to determine the direction of the graft incisions. This then determines the ultimate direction of the transplanted hairs growth. Thus a surgeon can use this technique to control and vary both the direction and angle at which the transplanted hair will grow in order to mimic the subtle changes in hair direction that occur naturally.

Each graft incision is created by analyzing the neighboring hair so the surgeon can reproduce the correct hair pattern. As a result, as each transplanted hair emerges from the scalp it will grow and lay in a similar direction as its neighboring non-transplanted hairs.

Lateral slits can enable denser packing of grafts

Lateral slit incisions also tend to be more parallel to the scalp and thus more superficial and less invasive to the scalp’s underlying vascular structure. This parallel alignment also enables a physician to place more grafts per square centimeter with out the grafts compressing or popping up since the pressure exerted on the grafts does not push them upward from the scalp.

Using blades cut to the size of the grafts

Some of our members use custom blade cutters to create tiny blades to make incisions that match the size and depth of each follicular unit graft being transplanted. This enables a surgeon to safely dense pack more grafts into a given area during a surgical session. Healing time is also more rapid, with minimal scarring.

Typically most clinic’s blades range from 1.5mm to 2mm in size. However, by using the custom blade cutter our physicians can create blades as small as .7mm for a single hair graft and .9mm for a multi hair graft.

In addition, the blades created by the custom cutter are squared off to match the shape of the bulb end of a hair follicle. Non custom cut blades are typically spear pointed which requires them to be inserted deeper thus causing more trauma to the scalps vascular structure.

The ability to control the depth of the incision each blade makes is also critical. Each blade is placed in a blade holder that is set to not allow the blade to go any deeper than required for the graft to being placed in the incision. This minimizes unnecessary trauma to the deep vasculature of the scalp, thus enabling close tight incisions, minimal tissue swelling, and quick healing that leaves no visible scaring, pitting, or cobble stoning of the scalp.

Placing grafts to maximize their aesthetic result and coverage

The plane and direction in which each follicular unit graft is placed on the scalp can also impact the ultimate appearance of density that can be produced with a given number of grafts. This is because hairs within a follicular unit are typically next to each other inline.

Therefore by arranging each multiple hair graft on the scalp in a linear fashion to the line of sight, each follicular unit will provide the maximum appearance of fullness and scalp coverage. This also mimics how hair is normally aligned on the scalp.

Viviscal's hair growth vitamin and dietary supplement taken twice daily promises to "reverse hair loss" and grow thicker hair in both men and women experiencing balding and thinning hair.  Its primary activeingredient, AminoMar C™ Marine Complex, is said to be a proprietary blend of ingredients and proteins that "provides the essential nutrients needed to nourish thinning hair and promote existing hair growth".

The entire Viviscal product line includes an "all natural" dietary supplement, a shampoo and conditioner, and a scalp lotion.  Viviscal is promoted as being 100% natural, drug-free, gluten-free and safe from harmful side effects. But can Viviscal deliver on its promises to reverse hair loss and grow new hair?

In 2011, Viviscal advertisement was banned in the United Kingdom by the Advertising Standard Authority (ASA) who deemed that its claims to maintain optimum hair health were unproven. The ASA concluded:

"Because the evidence sent did not show that the ingredients in Viviscal had been shown to have a positive effect on hair health, we concluded the claims that the product could 'nourish hair follicles' had not been substantiated' and ruled the advert cannot be broadcast until it is changed."

However, as with many similar products promising to grow hair, substantiating their hair growth claims may not be a simple task.

Viviscal’s manufacturer does reference a number of studies that seem to support their claims of growing thicker hair. For example, the results of "Scientific Pilot Study #1" on 40 hair loss suffering females with an average age of 35 concluded, "Viviscal was well received by test subjects and the analysis of hair counts showed a mean reduction in hair loss of 46% in only 10 weeks." Additional studies are cited on Viviscal’s website.

Recently, we learned that Dr. Glenn Charleshas publicly endorsed Viviscal.  Dr. Charles has an outstanding reputation for performing state of the art hair transplant surgery and is a highly esteemed member of the Coalition of Independent Hair Restoration Physicians.When asked to comment on his public endorsement of Viviscal, Dr. Charles stated:

"I have never had any hair loss patients display any negative effects. I describe it to my patients as a natural supplement that can promote a healthier scalp and hair. It may also, in turn, slow down the hair loss process. I tell all my patients that there are no guarantees with this product.  Although most patients believe that they did have improvement after using this product, I admit that some patients do not see any noticeable changes that either they or I can identify."

Other hair loss experts are not as optimistic regarding Viviscal’s hair growth potential. Coalition member Dr. Bill Rassmanof Los Angeles states:

"I am skeptical of the photographs (results) and the changes shown make me doubt what the Viviscal marketing department wants me to see. Viviscal reportedly contains ‘special marine extracts and a silica compound’ - and yet I’m to believe this will regrow hair? If these photos were real, the product would have taken over the market years ago."

It's also important to note that Viviscal does notmake any claims on their website that their products can reverse the effects of genetic hair loss.  Instead, it simply states, "Viviscal works to reverse hair loss due to stress, poor nutrition, and many health related ailments".

So is Viviscal an effective hair loss treatment? More research may be needed before this question can be effectively answered. 

While there may be no harm (potential side effects) in trying it, at an average cost of $600 per year there are certainly more affordable and proven treatments available. The only clinically proven and FDA approved medical hair loss treatments currently available are Rogaine (minoxidil) and Propecia (finasteride). While Rogaine may be used by both male and female patients, Propecia is safe and approved only for male hair loss sufferers. Always consult your physician before adding any treatment to your hair loss regimen.

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.
