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.

Is this hair loss treatment effective?

Extreme Hair Therapy (EXT) for thinning hair is a 5 "step" hair loss treatment solution created by Hair Club that claims not only to rejuvenate your hair, but "rejuvenate your life".  Making claims to be FDA approved, EXT claims to stimulate hair regrowth in thinning areas by keeping hair in the anagen (hair growth) phase longer.

Balding men and women seeking hair loss solutions should be careful to do their due diligence in researching all products they are considering.   Is this one of the hair loss products that really works to treat baldness?  Can Extreme Hair Therapy really deliver what it promises?

Below we take a look at each of the 5 “steps” and separate treatments and analyze whether or not EXT can remedy alopecia in men and women.

What is the 5 Step Process of Extreme Hair Therapy?

Step One: Moisturizing or Revitalizing Cleanser
This moisturizing shampoo is rich with vitamins and works to cleanse the scalp. Though it claims to revitalize and strengthen thinning hair, the ingredients are not listed on their website. Many hair rejuvenators and thickening agents (commonly referred to as volumizing shampoos) help to make hair appear thicker as they take on hydration and swell. Unfortunately, these thickening agents do nothing to stop the progression of male pattern baldness, even if it temporarily makes the hair shaft appear fatter.

Step Two: Enzyme Scalp Cleanser
Claiming to be a “new breakthrough”, this organic formula removes sebum oils that can sometimes hinder hair growth. Though sebum buildup, excessive dandruff, and scalp dermatitis are sometimes responsible for certain non-genetic types of balding such as diffuse alopecia or telogen effluvium, it does not promote androgenic alopecia (hereditary male or female hair loss).

Step Three: Energizing Conditioner
Adding nutrients such as proteins and wheat amino acids, this conditioner helps to promote a healthy scalp and hair growth. It should be noted that nothing in this step claims to stop hair loss or stimulate hair regrowth.

Step Four: Hair Revitalizing Complex
This dietary supplement containing Vitamins B3, D, and E, Biotin, saw palmetto and nettle root is taken twice daily, once in the morning and once at night. Some of these ingredients can also be found in several other hair loss products such as Provillus, Procerin, and Avacor.

Though some of these ingredients work to treat benign prostatic hyperplasis (BPH) in men by inhibiting DHT (the hormone responsible for female and male pattern baldness), no formal clinical studies have been performed on successful hair loss treatment. It should be noted that tocotrienol molecules in Vitamin E may effectively treat alopecia but its counterpart tocopherol (commonly found in alternative herbal hair loss treatments such as HairMax MD), is not supported.  Additionally, because there are no regulations on herbal medications in the United States, the daily recommended value and dosage in Extreme Hair Therapy is based on something other than FDA regulation.

Step Five: Minoxidil (2% or 5%)
Minoxidil (the active ingredient in Rogaine and Xandrox) is an FDA approved hair regrowth formula and is used by many balding men and women with great success. Because Extreme Hair Therapy includes this, they are legally allowed to claim it to be FDA approved.

Costs:

Unfortunately, this information is not available on the Hair Club website. Upon calling the toll free number for this information, we are told that we must schedule a consultation with a Hair Club specialist. Customer service representatives are apparently not provided with this information.

Side Effects and Warnings:

No EXT side effects are reported on the Hair Club website however, Minoxidil may cause scalp irritation or redness, chest pain, a rapid heartbeat, faintness, swelling of the hands and/or feet, and unwanted facial hair growth.  Be sure to discuss the use of herbal medication with your physician before taking them. Saw Palmetto should be avoided by pregnant women with hair loss.

Conclusions:

The only FDA proven ingredient in Hair Club’s Extreme Hair Therapy hair loss treatment is Minoxidil.  Though Saw Palmettoand nettle root may be effective in treating men with an enlarged prostate by inhibiting DHT, no formal tests have been performed on them.

An Active Ingredient in Several Topical Hair Loss Treatments

Azelaic acid is a naturally occurring substance found in whole grains that contains a mild antibiotic designed to “clean” skin.  It is also said to be a potential inhibitor of 5-alpha-reductase in human skin.  A reduction of this enzyme may reduce the amount DHT (dihydrotestosterone) in the body and therefore, have a similar effect to finasteride; the active ingredient in FDA approved oral hair loss solution Propecia (finasteride). In theory, applying azelaic acid to the scalp may prevent or eliminate the binding of DHT to the hair follicle receptor, preventing hair loss and potentially stimulating hair regrowth.  Azelaic acid can be found in many prescription acne medication and topical hair loss products like Xandrox and Provillus. 

Combining azelaic acid with FDA approved hair regrowth solution minoxidil in a single topical product in theory, may prove to be a more powerful hair loss treatment for androgenic alopecia than minoxidil alone.  This is why some conjecture that Xandrox may be a more effective treatment than Rogaine (minoxidil). 

Azelaic acid has not been clinically proven effective as a standalone treatment for treating genetic female hair loss and male pattern baldness. It has also been known to irritate the scalp when applied topically.  Though there is a low percentage, azelaic acid may interact with other medications.  Be sure to consult your physician before using azelaic acid while on other medications.

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.
