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.

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.

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.

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.

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.

There are several topical treatments like Revivogen, Crinagen, Progesterone Creams, Kevis 8 and Xandrox that claim to minimize or block the amount of dyhydrotestosterone (DHT) present in the scalp.

DHT acts as a catalyst for the hair loss process as it binds with the receptor sites in hair follicles that are genetically vulnerable to hair loss. Over time, this process of DHT acting on the genetically vulnerable hair follicles hurts their ability to grow healthy hair.

The success of these topical treatments in reducing DHT levels in the scalp has not been clinically proven. However, the possibility of reducing DHT only in the scalp region rather than through out the entire body as with Propecia or Avodart is appealing.

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.
