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.

Causes and Treatments

Alopecia is the medical name for hair loss to the scalp or body.  While Androgenetic Alopecia (genetic hair loss) is the most common, there are many other forms of alopecia related hair loss worth discussing.  Each medically named alopecia comes with distinct symptoms, a unique cause and exclusive treatments. Below, we've compiled a list of and description for the most common types of alopecia related hair loss along with the available treatment options for each.

While the information on this website can be used as a guide, men and women who believe they are experiencing hair loss should always be properly diagnosed by a qualified hair restoration physician to determine its cause.

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.

Their recommendation is continued as long as they continue to show evidence of excellent patient results and satisfaction. If a patient expresses concerns, physicians are expected to resolve their concerns. We ask that patients first contact a physician with any concerns so that they can resolve them before publicly posting.

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.

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.

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.

Our physician members perform a very refined hair transplant procedure called "Follicular Unit Hair Transplantation". Today there are two methods for doing this procedure. They differ only in the methods used to harvest and prepare the grafts.
