New Entity “Retrograde Alopecia” Can Effect Your Hair Transplant Result !!

Retrograde alopecia is a form of hair loss that affects the lower portion of the neck called the nape and the sides of the scalp just above the ears. This condition is fairly common among individual’s suffering from hereditary hair loss.

Retrograde alopecia is not very well known but is found to be very common among the general population. It is estimated that approximately two out of three hair loss sufferers experience some degree of retrograde alopecia in addition to their more obvious male patterned hair loss problems.

Retrograde alopecia can manifest similarly to normal male patterned hair loss in that it occurs in various locations of the scalp with varying degrees of severity but these areas are limited to the back and sides of the scalp below the borders that are defined in the Norwood Hamilton hair loss chart.

Retrograde alopecia can also be referred to as “vertical alopecia” due to the fact that it usually involves thinning and density reduction in a vertical fashion, moving up from the nape of the neck into the lower occipital zone (traditional donor area) of the scalp with rare cases reaching the occipital bone.

Other forms of retrograde alopecia can include vertical thinning on either side of the scalp above the ears, leaving a distinct demarcation between lower density hair closer to the ears and higher density hair higher on the scalp. In some cases this higher density hair manifests in a narrow band of hair that should be avoided in any surgical hair restoration.

Can I have a hair transplant with Retrograde Alopecia?

The main concern with hair transplant surgery is how far the hair loss will extend. In some cases, patients may have extensive hair loss above their nape reaching in to what is called the permanent zone. In addition, many patients confuse retrograde alopecia with another condition called Diffused Un patterned Alopecia (DUPA). While both conditions may appear similar at first, they are totally different.

DUPA is a type of androgenic alopecia (genetic hair loss). DUPA can affect both men and women. DUPA is a sub-type of androgenic alopecia. The difference between male pattern and female pattern hair loss is that DUPA does not follow any pattern. Therefore, the back and sides of the scalp may be susceptible to thinning.

DUPA is categorized as diffuse thinning over the entire scalp. Unlike Diffused Patterned Alopecia (DPA), DUPA lacks the stable permanent zone associated with other forms of alopecia. DUPA is defined as a general decrease in the density of hair without any definite pattern.

Hair transplant surgery is not an option for individual’s with DUPA, as there is no permanent donor supply. However, retrograde alopecia is contained to a specific portion of the scalp, specifically the sides above the ears and nape.

Individuals with retrograde alopecia may be suitable candidates for surgical hair restoration however retrograde alopecia would decrease their overall lifetime donor supply. Therefore, prospective patients with retrograde alopecia may need to adjust their expectations and goals accordingly.

Patients with retrograde alopecia have thinning in the permanent donor region. This means follicles from this region can’t be used in hair transplant surgery. They may thin or shed in the future, so they should not be transplanted. These patients are generally not good surgical candidates. However, all patients who believe they suffer from retrograde alopecia or a diffuse thinning pattern should be evaluated by a hair loss expert in-person.

Is There A Pattern To Retrograde Alopecia?

Retrograde alopecia can also be seen on the sides of the scalp, forward of the ears in the lateral temporal region, leaving the frontal sides of the scalp very thin. Oftentimes it continues above the side burns but not affecting the sideburns specifically and other times the sideburns are also partially affected. Retrograde alopecia can also manifest as an “arch” that not only includes the areas above the ears but also behind.

It is highly recommended that the finer hairs found in an area of the scalp affected by retrograde alopecia to be excluded from any hair restoration procedure as they are sometimes mistakenly harvested for their finer caliber diameter.

The common purpose is to use them for the frontal hairline, which ultimately leads to failure since they are being miniaturized, and either does not survive the transplantation process or fail to continue to grow after hair transplantation due the issue of continued miniaturization and eventual follicular death.

Treatment of retrograde alopecia is rarely with the use of surgical intervention and it is highly recommended to avoid surgical reconstruction of regions affected by retrograde alopecia. Medical treatments such as Rogaine are the preferred treatments as well as auto blood and plasma therapies and potentially LLLT (low level laser therapy).
