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.

The Ultimate in fullness and naturalness in one surgery session.

We’ve all seen the “pluggy” hair transplants of the past. But we don’t see today’s state of the art hair transplants because they go unnoticed.

Plugs Mini Micros Follicular Units

Follicular Evolution - from plugs to micro grafts to ultra refined grafts

Surgical hair restoration has dramatically evolved from the big round “plug” grafts of the 1960 ’s and 70’s, to the “mini micrografts” of the 80’s and early 90’s, to modern hair transplant procedures using entirely follicular unit grafts .

Now hair restoration surgery is going through another important evolution that is improving both the naturalness and fullness that can be achieved from any one surgical hair transplant session.

Ultra Refined Grafting - Smaller Blades, Incisions and Grafts

Today ’s micro surgical blades, like the size of hair grafts, have become ever smaller and now enable hair transplant surgeons to safely make more tiny graft incisions in a given area then ever before. Surgeons are then able to “dense pack” select areas with as many as 40 to 60 follicular unit grafts per square centimeter. This graft density is as much as twice that of the standard follicular unit hair transplant procedure.

Such high densities of transplanted hair typically produce the appearance of fullness even after only one surgical session. Patients also experience rapid healing and no visible skin distortions due to the tiny size of these incisions.

Ultra Refined Follicular Unit Grafting - Hard on the clinic but easy on the patient.

Ultra refined follicular unit grafting raises the bar for physicians and their staff. This delicate and demanding hair transplant procedure requires more skill and careful attention to be performed properly. The smaller and more tightly packed incisions require more closely dissected follicular unit grafts that are carefully trimmed under microscopes. These small and densely packed incisions are also more difficult to place the grafts into.

This procedure also requires more careful patient selection, as “dense packing” of grafts is not appropriate for all patients.

Ultra Refined Follicular Unit Transplantation – the new “Gold Standard”

In the hands of a highly skilled physician and staff the Ultra refined follicular unit hair transplant procedure can achieve excellent new hair growth that is so natural that it is undetectable even under close scrutiny.

While the standard micro “follicular unit” hair transplant does produce natural looking results, its ability to achieve high density in only one surgical session is limited. Thus patients may have to do subsequent surgical sessions in a transplanted area to achieve a full look.

The many patient benefits of this new procedure are significant and include:

• The ability to get excellent hair density in only one surgical session.
• Minimal trauma in the graft recipient area with rapid post surgical healing.
• Little or no visible pitting or distortions in the transplanted areas.
• More natural direction and angulation of the transplanted hair.

Crinagen is an all natural alcohol-free topical scalp spray clinically backed to reduce the amount of DHT (dehydrotestosterone) in the scalp. It contains no alcohol, and has displayed no side effects. Crinagen is also equally safe for men and women and is most effective in men and women with thinning hair. In addition to blocking scalp DHT, they both are reported nourish the scalp’s hair follicles. Crinagen usually displays its effects on average in five months.

How It Works:

The product's main ingredients are Saw Palmetto, Zinc, and Azelaic Acid. All 3 ingredients are reported to reduce the production of scalp DHT and nourish the scalp's hair follicles.

Developing Realistic Expectations:

Crinagen has not been clinically proven nor approved by the FDA. Thus, like Revivogen and Tricomin, Crinagen should be used only after seriously considering proven treatments like Propecia (finasteride) and Rogaine (minoxidil).

Don't expect immediate results. It's recommended to use Crinagen 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 Crinagen is working for you.

Hair shedding is a common symptom the first few months and a sign that the medication may be working for you. It's crucial to push past this stage with continued use for the recommended period of time.

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.

For many hair loss suffering men and women, topical concealers are a necessary aspect of the "daily routine." Usually composed of hair shaft adhering microfibers or darkening cream, concealers help balding men and women both camouflage areas of noticeable baldness and increase the apparent density of thinning hair. Below, we provide our readers with a product review of the new and popular hair loss concealer Caboki.

Caboki was released back in 2005 but is only just now receiving more attention, most likely due to increased advertising. Like others before it, Caboki concealer claims to be a "hair loss breakthrough". Despite ambitious promises, Caboki's claims leave several unanswered questions: is Caboki really a breakthrough concealer? How does it compare to other, similar products like Toppik, DermMatch and COUVre? Is Caboki a worthwhile product for purchasing, or will it fall from grace like other alleged "breakthrough" hair loss miracles before it?

While many products, such as "Toppik" (a popular microfiber-style concealer) and "Couvre" (a concealing cream) are popular and trusted within the hair loss community, new, unproven concealers arrive on the market every day. What's more, many of these new concealers try to "best" the products currently offered and claim to camouflage hair loss in a way "never seen before." However, as with many alleged miracle cures, these products often fail to meet expectations and leave hair loss sufferers disappointed and discouraged. So let's explore how Caboki works to conceal hair loss below.

Caboki is comprised of a series of charged microfibers that, when applied to the scalp, tightly bind hair shafts and create a denser, fuller appearance. According to the manufacturer, these microfibers are comprised of two different elements: Moroccan Gossypium Herbaceum fiber and iron oxide-based natural (mineral-based) colorants. The makers of Caboki claim these elements allow the product to create a natural, healthy appearance, capable of withstanding harsh lighting conditions, sweat, wind, and rain.

However, because these elements have been used in other concealer products (Toppik particles, for example, are both charged and made from natural keratin), Caboki still must demonstrate why it's revolutionary. So, what makes Caboki a "hair loss breakthrough?" According to the manufactures, Caboki differs from other concealers in the following ways:

• Caboki particles, unlike other microfiber concealers, are negatively, not positively charged. Allegedly, positively charged particles (usually made from wool fibers) possess a greater tendency to repel and oppose not only each other, but also the positively charged hair shafts. Because of this, when the particles attach near each other on a hair shaft, they are more likely to repel and detach. According to Caboki creators, negatively charged fibers (made from Moroccan Gossypium Herbaceum fiber) do not experience this intense phenomenon, and create a much greater (200%), electronically attractive (negative to positive), bond. If this is true, Caboki microfibers should bind and adhere to hair shafts with a much stronger, more permanent affinity.
• Because Caboki particles create a stronger charged bond, the thicker, more volumized hair shafts are likely to stand erect and less non-bonded concealer will collect on the scalp. This combination, according to Caboki, will eliminate the "dull, flat" appearance associated with other concealer products.
• By only utilizing natural elements (Moroccan Gossypium Herbaceum fibers and iron oxide colorants), Caboki avoids some of the potentially harmful synthetic dyes, fillers, and artificial preservatives used in other concealer products.

So, it's now clear why the manufacturers of Caboki believe it is a superior product, but does this mean Caboki is a legitimate hair loss concealer? Does it truly outshine other concealer product currently on the market?

While the product is still fairly new, most anecdotal experiences and testimonials from real hair loss suffering men and women are positive. Most individuals believe the negatively charged Caboki particles bind strongly to the positively charged hair shafts and create a longer-lasting increase in density. Furthermore, the particles seem to be more resistant to potentially damaging elements like water, sweat, and wind. Having said that, many individuals report some common problems experienced with other concealer products – concealer wiping off on pillows and clothes, some smearing with sweat, and difficultly creating a natural appearance in the hairline. However, these same individuals claim the problems occur less frequently with Caboki. Altogether, it's likely that Caboki is both a helpful hair loss concealer and equivalent to other products currently on the market. While it is clear that Caboki does possess some advantages and interesting claims, it could be difficult to quantify whether it truly exceeds or simply meets the standard set by other available hair loss concealers. Truthfully, only time and the opinion of hair loss sufferers will determine whether Caboki lives up to its claims and defines itself as a legitimate concealer breakthrough.

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.

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.
