Hair loss is a universal condition, affecting all ages, races, genders and nationalities. It’s estimated that “androgenetic alopecia,” or male and female pattern baldness affects 35 million men and 21 million women in the United States alone. This section examines how race, age and gender affect hair loss.

Race and Hair Loss

In physiological terms, human beings are all composed of the same bones, muscles, and everything else down to the cellular level. But there are specific differences.

Hair, in all of its variations, is one area in which human beings display their differences. Hair follicles can widely vary in terms of color, length, shape, thickness, strength and various other factors.

There are many ethnic groups to consider. But we will focus on the special considerations of Asians, Blacks (of African descent) and Caucasians.

Asian Hair Loss Considerations

Asian people typically have very straight hair. Their scalps contain fewer hairs per square centimeter, they actually have a lower hair density than that of Caucasian hair follicles. But because the individual hair follicles of East Asians are thicker, this gives the look and impression of greater hair density.

For these reasons, hair restoration techniques for East Asians, much like other races, must be sensitive to a variety of anatomic and cultural differences. For instance, East Asian females often have an increased likelihood of developing “diffuse alopecia,” or hair that thins evenly over the entire head than Caucasian females.

Even though it’s not a definite requirement, it’s very helpful for Asian patients to seek out doctors with experience in Asian hair.

Another consideration for East Asians considering hair restoration surgery is the increased chance of developing keloid scars. A keloid is a thick, irregularly shaped and elevated scar with uncontrolled growth that results from excess fibrous skin tissue. East Asians typically have a greater likelihood of keloid development than Caucasians, but less than that of people of African descent. Therefore, before undergoing surgery, East Asians may want to consider being medically evaluated for keloids.

African Hair Loss Considerations

People of African descent usually possess naturally curly hair. This curly hair gives the visual impression of increased hair density for a given amount of hair, which is beneficial in hair restoration surgery.

The hair follicles beneath the skin of people of African decent also typically curve more than Caucasians. This can make harvesting the donor hairs, without severing or transecting the hair follicles beneath the scalp, more difficult. A hair restoration physician needs to be very aware of this difference and adjust to its requirements.

As in the case of East Asians, people of African descent possess some unique hair and skin characteristics. Some of these medical conditions are more common in black skin than in white skin. This may increase the risk for post-surgical complications.

Those of African descent have a higher chance of developing keloid scarring when injured. This in turn leads to a greater chance of noticeable donor scars. Keloids aren’t a widespread problem. But those with a history of them are carefully evaluated in regard to their existing scars. The evaluation usually involves a small "test procedure" to determine if there’s a normal healing rate.

Another issue is that of postoperative skin discoloration. With darker skin, there’s often a greater risk of both increased and decreased skin color after injury or surgery. These risks can be determined by the patient’s medical and family history.

Ingrown hairs are also a more common problem in darker skin. If a patient has a history of ingrown hairs or other minor skin infections, this may signal a higher risk for ingrown hairs post-hair restoration surgery. Again, this risk can be determined by a small test procedure.

Caucasian Hair Considerations

Caucasians (white people) may have a wide range of hair and skin types. However, if someone has dense and or coarse hair, as well as skin color similar to their hair color, they will generally achieve the best results for a given amount of restored hair.

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.

In women with PCOS(polycystic ovarian syndrome), high levels of androgens (male hormones) in the body may cause hair loss. DHT (dihydrotestosterone), more abundant in men, is created from a combination of testosterone and5-alpha-reductase enzymes. DHT can bind to hair follicle sites, accelerate the natural hair growth cycle, and cause hair to go into resting (catagen) sooner causing thinning hair with each cycle.

Women with PCOS are more susceptible to androgenic alopecia, more commonly referred to as male pattern baldness or genetic female hair loss. Androgenic alopecia is also the number one cause of hair loss and thinning hair in the world.Women with androgenic alopecia typically lose hair in a pattern similar to the ludwig scale,and less commonly the norwood scale.

If you suspect you have PCOS, you should consult with a physician and get tested for it. Only a physician can diagnose you and recommend a proper treatment.

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.

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.

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.
