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.

We believe that patients have a right to full disclosure and a complete understanding of exactly what hair restoration surgery involves.

This step by step presentation shows how today’s state of the art follicular unit hair transplant procedure is typically performed.

Patient is prepared for surgery

During surgery hair follicles from the back of the head that are genetically resistant to going bald will be removed and relocated (transplanted) to the balding areas.

Donor area is trimmed

Prior to surgery, the hair in donor area that will be surgically removed is trimmed.

Donor area is prepared for surgery

Once the donor area has been prepared it is given local anesthesia.

Donor tissue is removed

The donor tissue containing the bald resistant hair follicles is then surgically removed.

Donor area is sutured

The donor tissue containing the bald resistant hair follicles is then surgically removed.

Hair combed over sutures

When patient’s hair is combed over the donor area the sutures are not visible. These sutures are typically removed approximately ten days after surgery.

Donor tissue is trimmed into follicular unit grafts

Surgical technicians then use microscopes to view the donor tissue in order to dissect and prepare follicular units hair grafts.

Bald recipient area is prepared

After being given local anesthesia, the balding recipient area is ready for surgery. No trimming or shaving of hair is needed in the top recipient area.

Incisions are made in the balding areas

Tiny incisions are made in the recipient areas in irregular patterns that mimic nature. The follicular unit grafts will then be placed carefully into these tiny incisions.

Grafts are placed into the incisions

Follicular unit grafts are gently placed into the recipient incisions.

Grafts are placed in varying densities

Typically the smallest one and two hair grafts are placed in the very front of the hairline, with three and four hair grafts placed behind them.

Patient immediately following surgery

Following surgery a patient will have hundreds of tiny incisions with short hair stubble showing from the new grafts.

Close up of recipient area after surgery

The tiny graft incisions heal rapidly. The redness and scabbing in the recipient area normally clears up within about one week.

If you are going bald you should seriously consider hair loss medication treatments to halt or even reverse your hair loss. While there is no “Hair Loss Cure”, hair loss drugs like finasteride (Propecia) and dutasteride (Avodart) can often stop or even reverse alopecia areata in most people.

However, just like any other drug, Propecia is accompanied by a list of potential side effects, some of which have been more recently reported as potentially long term.  You can read more about this in the "What About Side Effects" section further down this page.

Studies have shown that 80% of men using Propecia stopped or even reversed their hair loss to some degree. Preliminary clinical trials for Avodart appear even more effective than Propecia.

However, neither Propecia nor Avodart has been proven to restore hair in the frontal areas. For reasons yet unknown these drugs, along with Rogaine, only generally work in regrowing thinning hair in crown area of the scalp. Only hair transplant surgery has been successful in restoring hair in the frontal hairline area once it has been lost.

Propecia and Avodart are also less effective in growing hair in older men. These hair loss drugs work best for men who have been balding for less than five years.

Women must NOT USE Propecia

Both Propecia and Avodart are not recommended for use by women or children.

It’s been found that these drugs can cause birth defects. More specifically, these birth defects may occur when large amounts of the drug are absorbed into the body during the period of foetal development.

Physicians advise pregnant women to not handle Propecia tablets, as this may harm male foetuses. But as of yet, there has not been a single reported case of birth defects caused by handling these tablets.

Furthermore, there’s also no evidence that pregnant women exposed to the semen of Propecia or Avodart patients will risk any birth defects.

Propecia and Avodart are also not advisable for men with liver disease or prostate cancer.

Get a Prescription for Propecia or Avodart.

Often our member physicians will prescribe Propecia or Avodart to halt a patient’s hair loss and then restore the hair already lost with hair transplant surgery. These treatments in combination can work synergistically. The drugs work to halt the hair loss, while hair restoration surgery restores what was lost.

To get a prescription for Propecia or Avodart schedule a free no obligation consultation with any of our quality hair restoration physicians. Find a physician in your area.

Propecia and Avodart should be taken once a day. It has been found that after two years of treatment, Propecia effectively grows hair in about 66% of patients. Also, about 83% of the subjects receiving this treatment continue to maintain their existing hair after two years.

Propecia (Finasteride) was originally a drug called Proscar, which was used to treat and reduce men's prostate conditions such as benign prostatic hyperplasia (BPH).

Its parent company, Merck & Co., soon realized that the drug had a unique side effect - it grew hair on bald men's heads.

In December 22, 1997 the FDA approved Propecia as a hair loss pill. Merck & Co. then marketed the drug as a hair loss treatment under the trade name of Propecia.

More recently Dutasteride, sold as Avodart, has generated interest as a promising new hair loss medication. Like finasteride (Propecia) it inhibits the creation of DHT and was originally developed as a treatment for men’s prostate condition.

However, unlike Propecia, Avodart inhibits the creation of both type one and type two 5 alpha reductase enzymes. Dutasteride has been shown to decrease levels of DHT by 90% after only two weeks, making it a more powerful and faster acting weapon against hair loss than Propecia (Finasteride).

Dutasteride is not yet FDA approved for the treatment of hair loss. However, some hair restoration physicians also prescribe it for the treatment of hair loss. Like Propecia, Avodart is not safe for women and children.

Sticking with the program to see results

Losing your hair took time. So too will regrowing your hair using Propecia or Avodart. These drugs require patients to take the drug daily for at least three months before any obvious changes will be noticeable. Most physicians advise taking these drugs for a year before evaluating their effectiveness.

At this time, Propecia and Avodart are only available by prescription. Our member physicians are available to discuss these hair loss drugs with you and prescribe them if appropriate. To find a quality hair restoration physician in your area.

Other DHT Blockers

Aside from Propecia and Dutasteride, there are other treatment options (all topical) that may or may not work to block the effects of DHT on vulnerable hair follicles. These include Revivogen, Crinagen, Progesterone Creams, and Xandrox (a type of minoxidil). Other DHT Blockers

To learn more about these treatments, as well as all other topical options, visit our Topical Hair Loss Products and Treatments section.

How hair loss drugs inhibit DHT and Alopecia Areata

Baldness is largely the result of dihydrotestosterone (DHT) interacting with those hair follicles that are genetically vulnerable to their effects.

DHT is essentially the active ingredient or catalyst for the hair loss process. DHT binds with the receptor sites of genetically vulnerable follicles and gradually degrades the follicles ability to produce healthy hair. This eventually results in baldness in the affected areas.

Hair loss drugs like Propecia or Avodart work by inhibiting the conversion of testosterone into dihydrotestosterone (DHT). By reducing the amount of DHT present in the scalp the hair loss process is slowed and in some cases even reversed.

What about side effects?

Up until a couple of years ago, side effects when taking Propecia or Avodart were only considered temporary. However, over the last several years, many me have reported ongoing side effects from Propecia even after stopping treatment.  This more permanent condition has become known as "Post Finasteride Syndrome" or (PFS). Side effects included but aren't limited to reduced semen production, a reduced libido and softer erections.

As a result, in April of 2012, the FDA mandated labeling changes to finasteride related products.  Labeling changes to Propecia include "libido disorders, ejaculation disorders, and orgasm disorders that continued after discontinuation of the drug".  Labeling changes to Proscar include "decreased libido that continued after discontinuation of the drug".  Labeling changes to both Propecia and Proscar include "reports of male infertility and/or poor semen quality that normalized or improved after drug discontinuation".

While most men don't experience any side effects at all, it should be known that a small percentage of men may experience persistent side effects even after stopping treatment.  Most men who experience side effects however, only experience them temporarily and stopping treatment makes them go away.

It was Hippocrates, the “Father of Modern Medicine”, who first recognized a connection between hair loss and the sexual organs. Hippocrates’ studies of eunuchs (men castrated before puberty) observed that these men did not suffer from hair loss.

We know today that this is due to the absence of testosterone, which is normally converted into dyhydrotestosterone or DHT – the active ingredient in baldness. In March 1995, Duke University researchers came to the conclusion that " . . . while castration may be a cure, it is not commercially acceptable."

Hippocrates had a personal interest in finding a cure for baldness as he suffered from hair loss. He developed a number of different treatments including a mixture of horseradish, cumin, pigeon droppings, and nettles to the scalp. This and other treatments failed to work and he lost the rest of his hair. The area of permanent hair on the back and sides of the head (from which donor hair is taken for hair transplants) is also known as the “Hippocratic wreath.”

Ancient Rome and Hair Loss

Moving from Greece to the Roman Empire, we find that Julius Caesar employed a variety of methods to hide his thinning hair. In addition to the laurel wreath that he wore, he first grew his hair long in the back, and then combed it forward over his bald spot. Yes, the “Comb Over” is ancient.

Being a Eunuch – the sure way to stop baldness

In the 1940’s, the studies of Hippocrates and Aristotle were continued. Both men had concluded that eunuchs always kept all their hair.

This finding was backed up by the work of Dr. James Hamilton.

He discovered that certain male hormones (missing in eunuchs) were critical to the development of male pattern baldness.

A Viable Alternative to Propecia in Treating Hair Loss?

Folexen S-equol , produced by Australian manufacturer Eclipse Nutraceuticals is considered an "all natural" hair loss treatment that boasts an impressive 87% success rate for preventing and reversing the effects of male pattern baldness with virtually no side effects.  Folexen S-equol has also been a hot topic of discussion on our popular hair loss forum. But, does this self-described "nutraceutical" live up to its hair growth hype?  Is Folexen a viable alternative to Propecia for treating the effects of male pattern baldness?

What is Folexen S-equol?

According to the FAQ on Folexen's website, the active ingredient S-equol is "a metabolite of a natural isoflavone called daidzein, which occurs in soybeans and some other food products".

Isoflavones are an organic compound produced almost exclusively by various bean types. In populations that consume large quantities of soy protein, studies have shown a lower incidence of breast cancer and other common cancers because of its role in influencing sex hormone metabolism and biological activity.

As a metabolite, S-equol is the product that remains after the isoflavone is broken down or "metabolized" by the body.

In addition to its active ingredient, Folexen contains the following GRAS (generally recognized as safe) inactive ingredients: starch, maltodextrin, allantoin, propionic acid. It may also contain hypromellose (vegetarian capsule).

But is there any evidence that S-equol  works to treat hair loss?

How Folexen S-equol Allegedly Works to Treat Baldness

In the body, testosterone is converted to the hormone dihydrotestosterone (DHT) via the enzyme 5-alpha-reductase (5AR). It's widely known that androgenic alopecia (genetic hair loss) results when genetically vulnerable hair follicles are exposed to DHT which then binds to the receptor sites of these follicles causing them to weaken and shrink over time. This shrinking process is known as miniaturization.

The recognized leader in the battle against the balding effects of DHT is the clinically proven and FDA approved drug Propecia (finasteride). Propecia works by inhibiting the conversion of testosterone to DHT, potentially slowing or even reversing the effects of androgenic alopecia. However, approximately 2% of males who take Propecia experience debilitating sexual side effects.

Unlike finasteride, Folexen's rumored ability to suppress hair loss and potentially regrow hair is based on the theory that S-equol can bind strongly to free DHT molecules, prohibiting them from binding to the hair follicles' receptor sites. Because Folexen does not suppress the conversion of testosterone to DHT, there is no resulting increase of testosterone in the body and therefore, no sexual side effects. But are there any clinical studies supporting that S-equol can truly prevent DHT from binding to hair follicle receptor sites and prevent hair loss?

Clinical Studies

Folexen's website references four articles in peer reviewed journals. Two of these studies center on S-equol's effect on prostate health while the other two don't appear to reference S-equol at all.

At this time, there appears to be no scientific data presented supporting Folexen's efficacy as a hair loss treatment.

Side Effects

The company claims that the product is virtually side effect free: specifically noting that it does not cause gynecomastia (enlarged breasts), erectile dysfunction or any of the other side effects that are experienced with some other treatments.

Some users however, did report mild diarrhea that dissipated within one week of commencing treatment.

What is the Recommended Dosage?

The recommended dosage of Folexen is 4 capsules per day (two every 12 hours), totaling 10mg of the active ingredient. Eclipse claims that the product has been tested safe at much higher concentrations (up to hundreds of milligrams) and there is some speculation based on available data that it may, in fact, require a dose as high as 100mg to match the Propecia's hair growth results.

Where to Buy Folexen S-equol

Folexen is only available by mail order from Australia. A bottle of 100 2.5mg capsules (25 day supply) costs approximately $40 USD + shipping but there is a discount for purchases exceeding 4 bottles and again for 9+ bottles. However, it's easy to see that even in bulk this treatment is several times more expensive than purchasing generic 5mg finasteride and quartering the tablet, as many finasteride users do.

As a natural product and not a drug, there are no shipping restrictions. Estimated delivery time is two weeks.

Conclusion

Time will tell if Folexen S-equol proves to be an effective weapon in the fight against androgenic alopecia or simply another product in a long line of expensive disappointments.

One of the more popular hair loss products on the market today for those with thinning hair is Provillus. Available for both men and women, making promises to “re-grow beautiful healthy hair”, this product consists of a topical and oral solution with an FDA approved hair regrowth ingredient and a number of conjectured “all-natural” dihydrotestosterone (DHT) blockers.

Other ingredients that promote a healthy scalp and head of hair are also contained in this product. The theory behind Provillus is to revive the hair follicles with growth stimulators and attack hair loss at its source by blocking DHT.

In order to fully evaluate the efficacy of this product, we must further explore each ingredient to determine whether or not this hair loss treatment delivers what it promises. Below you will find a list of ingredients and information that will help you determine whether or not Provillus is right for you.

Topical Ingredients:

Minoxidil (found in Rogaine, Xandrox and other solutions) is an FDA approved hair growth treatment and many balding men and women use it with great success. This particular ingredient is what allows Provillus to advertise their product as FDA approved.

Azelaic acid has been found to clean the skin and potentially inhibit DHT, the hormone responsible for androgenic alopecia.

Combining these two “forces” therefore in theory, may be a more powerful treatment than minoxidil alone. However, no clinical studies have been performed on azelaic acid as a standalone product therefore, whether or not it can stop hair loss is purely conjecture.

Oral Ingredients:

The Provillus oral solution contains a number of supposed DHT blockers including saw palmetto for hair loss, Vitamin B6 and Zinc, pumpkin or cucurbita maxima, and nettle root. Because evidence exists that these ingredients may be an effective treatment for benign prostatic hypertrophy (BPH), theories have been produced that they might also effectively treat baldness. Though we can appreciate the aspiration for balding men and women to use herbal products as an “all-natural” replacement for Propecia (finasteride), the problem we have is that most of them only contain anecdotal if any evidence at all that they can successfully treat baldness.

Provillus oral solution also contains a number of components that are said to promote healthy hair growth and cleanse the scalp. These include eleuthero, uva-ursi, muria puama, horsetail, para-aminobenzoid acid (PABA), and magnesium. Understand however, that promoting a healthy scalp and hair is not the same as stimulating newhair growth and hair regrowth, nor does it signify an effective hair loss treatment.

Possible Side Effects

The only side effect that we could find listed on the Provillus website is an upset stomach. It is reported that taking it with food often stops this. Be sure to follow the links to the ingredients listed above as many of them also have potentially reported side effects. Consulting with a physician before taking any herbal hair loss medication is advised.

Dosage

Currently there are no standards on dosages of herbal medications in the United States. In addition, no formal clinical studies have been performed on them for treating baldness. Therefore, the suggested daily value listed on the ingredient package is based on something other than government regulation and scientific study.

Costs

A one month supply of Provillus topical and oral supplement for men or for women costs about $50 per month. Discounted prices are available when bought in bulk.

For the cost of Provillus, one can purchase generic finasteride and generic minoxidil which are FDA approved hair loss treatments for safety and efficacy.

Conclusions and Our Opinion

Given that Provillus topical treatment contains FDA approved hair regrowth ingredient minoxidil; we can at least agree that it may have some marginal benefit for men and women suffering from androgenic alopecia. However, due to the lack of compelling evidence in these other conjectured hair loss solutions, it may be more beneficial and cost effective to spend your money on Propecia (finasteride)for men only and Rogaine (minoxidil) that has helped balding men and women worldwide.
