What is Retrograde Alopecia?

Often overlooked in discussions about hair loss, retrograde alopecia is a distinct form that primarily affects the lower neck area, known as the nape, and the sides of the scalp just above the ears. This condition is particularly common among patients struggling with hereditary hair loss.

Despite its prevalence, retrograde alopecia remains relatively unknown to many. Surprisingly, statistics indicate that two out of every three individuals dealing with hair loss also experience some degree of retrograde alopecia—often overshadowed by the more prominent concerns related to male pattern baldness.

Similar to typical male pattern hair loss, retrograde alopecia can manifest in different areas of the scalp and vary in severity. However, its defining characteristic is that the affected regions are limited to the back and sides of the scalp, particularly below the boundaries defined in the Norwood Hamilton hair loss chart.

Retrograde alopecia, often referred to as “vertical alopecia,” is characterized by a vertical thinning and decrease in hair density. It typically progresses from the nape upward towards the lower occipital region, which is traditionally considered a donor area for hair transplants. In rare cases, it can extend up to the occipital bone.

Alternative manifestations of retrograde alopecia may result in vertical thinning on both sides of the scalp above the ears. This can create a distinct contrast between the lower-density hair closer to the ears and the higher-density hair located further up the scalp. In some cases, this high-density hair forms a narrow band that must be approached cautiously in any surgical hair restoration procedure.

 

 

 

“What Are the Symptoms of Retrograde Alopecia?“

Understanding the symptoms of retrograde alopecia is crucial for timely identification and effective management of this often-overlooked form of hair loss. These include:

 

• • Thinning at the Nape and Sides: A key symptom of retrograde alopecia is the gradual thinning of hair in the lower neck area (nape) and the sides of the scalp just above the ears. This thinning typically follows a vertical pattern, distinguishing it from other types of hair loss.

    Noticeable Changes in Hair Density: Retrograde alopecia presents with significant changes in hair density in the affected areas. Patients may observe a clear boundary between the lower-density hair near the ears and the higher-density hair further up the scalp.

    Vertical Progression: As the name suggests, retrograde alopecia usually progresses in a vertical manner. Hair loss begins at the nape and moves upward toward the lower occipital region, in rare cases reaching the occipital bone.

• • Narrow Band of Higher Density Hair: In specific cases, retrograde alopecia may present a narrow band of higher density hair.

• • Hereditary Connection: Retrograde alopecia is often linked to hereditary hair loss. Recognizing the familial connection and identifying patterns within the family can aid in early detection and intervention.

What Are The Causes Of Retrograde Alopecia?

Retrograde alopecia stems primarily from hereditary factors, with a strong genetic predisposition to hair loss being a key contributor. Patients with a family history of male pattern baldness or other hereditary alopecia forms are more prone to developing retrograde alopecia. The influence of genetics plays a pivotal role in determining the susceptibility of specific patients to this unique form of hair loss.

Beyond hereditary factors, hormonal imbalances also play a significant part in the development and progression of retrograde alopecia. Fluctuations in androgen levels, a group of hormones that includes testosterone, can impact the hair follicles, leading to thinning and eventual loss in the nape and sides of the scalp.

Additionally, environmental factors, such as exposure to certain toxins or pollutants, may exacerbate the condition, especially in individuals genetically predisposed to retrograde alopecia. Understanding the multiple causes of this condition is crucial for devising targeted interventions and effective hair loss treatment strategies.

How Is Retrograde Alopecia Diagnosed?

Diagnosing retrograde alopecia involves a meticulous process, blending clinical expertise and advanced tools to unravel its unique signature patterns. Dermatologists or hair loss experts conduct a thorough examination, scrutinizing specific areas such as the nape and sides above the ears for characteristic thinning patterns. The patient’s medical history, with a keen focus on familial hair loss, provides invaluable insights into potential hereditary factors.

During the scalp examination, dermatologists scrutinize affected areas for signs of inflammation, scarring, or follicular damage. Utilizing magnification devices, they delve into the minutiae of hair follicles, assessing their health and searching for distinctive markers of retrograde alopecia.

A non-invasive hair pull test involving gently tugging a small bundle of hair to evaluate shedding levels is conducted. In retrograde alopecia, where weakened hair follicles are common, the hair may easily dislodge. This test becomes a valuable tool for dermatologists, providing insights into the severity of the condition and facilitating the tracking of its progression.

In certain scenarios, a scalp biopsy is deemed necessary to confirm the diagnosis definitively. This procedure entails taking a small scalp tissue sample, examined under a microscope. Through this, dermatologists assess hair follicle health, identify potential inflammation or scarring, and eliminate alternative causes of hair loss.

 

Is There A Pattern To Retrograde Alopecia?

Retrograde alopecia exhibits distinctive patterns, adding complexity to its recognition and understanding. Beyond its presence on the lower neck (nape) and the sides of the scalp above the ears, this unique form of hair loss can extend its reach to the lateral temporal region, creating thinning in the frontal sides of the scalp.

Interestingly, retrograde alopecia doesn’t always stop at the sideburns; it might continue above them without specifically affecting this facial hair feature. In some instances, the sideburns themselves may experience partial effects, highlighting the varied nature of this condition. One intriguing manifestation of retrograde alopecia is the formation of an “arch.” This arch not only encompasses the areas above the ears but also extends backward.

What are the treatments for Retrograde Alopecia?

Treating retrograde alopecia, a distinct manifestation of hair loss, necessitates a comprehensive understanding of its treatment modalities. These include:

 

• • M*inoxidil: A topical medication known for promoting hair growth, m*inoxidil is often prescribed to stimulate hair follicles in affected areas.

• • Low Level Laser Therapy (LLLT): LLLT Utilizes low-level lasers to stimulate hair follicles and improve hair growth. It is non-invasive and can be used as an at-home treatment.

• • Finasteride: An oral medication that helps block the hormone responsible for hair loss, finasteride is often prescribed to individuals with retrograde alopecia to impede further hair loss.

• • FUE Hair Transplant (in selected cases): Surgical procedure involving the transplantation of hair follicles from donor areas to the affected region can be considered for patients with advanced retrograde alopecia.

• • Scalp Micropigmentation: SMP is a non-surgical cosmetic procedure involving the application of pigments to the scalp to simulate the appearance of hair follicles. It provides an illusion of fuller hair in affected areas.

Is Retrograde Alopecia Permanent?

Retrograde alopecia is generally considered a permanent condition, particularly when influenced by hereditary factors. The genetic predisposition to hair loss and the progressive nature of retrograde alopecia suggest that, without intervention, the condition may persist over time.

While treatments such as minoxidil, finasteride, and hair transplant surgery can help manage and slow down the progression, a complete reversal may not always be achievable. Early detection and proactive management play crucial roles in addressing retrograde alopecia, emphasizing the importance of seeking timely intervention to minimize long-term impact.

Can Retrograde Alopecia Be Reversed?

The reversal of retrograde alopecia remains a challenging prospect, particularly due to its association with genetic factors. While various treatments, including minoxidil, finasteride, and surgical interventions, aim to slow down the progression and promote hair growth, achieving a complete reversal may be limited. The effectiveness of these interventions varies among individuals, and success often hinges on factors such as the stage of retrograde alopecia, the chosen treatment modality, and the patient’s response to therapy. Early detection and proactive measures are the key to mitigate the impact of retrograde alopecia and potentially achieving partial restoration.

Can I Have A Hair Transplant With Retrograde Alopecia?

Retrograde alopecia confines its impact to specific regions of the scalp, namely the sides above the ears and the nape. For patients grappling with this condition, the prospect of surgical hair restoration may be an option. However, the progressive nature of retrograde alopecia poses challenges over time, diminishing the overall donor supply. As a result, prospective patients must carefully manage their expectations and goals in light of the condition’s evolving nature.

Thinning in the permanent donor region is a common occurrence for patients with retrograde alopecia. Follicles from this area, essential for hair transplant surgeries, may not be viable due to potential thinning or shedding in the future. Consequently, patients with thinning in the permanent donor region may not be ideal candidates for surgical interventions. Those suspecting retrograde alopecia or experiencing a diffuse thinning pattern are advised to seek an in-person evaluation by a hair loss expert before undergoing a hair transplant procedure.

Hair transplant procedures can be considered for patients with mild retrograde alopecia, particularly when the occipital region remains unaffected. The key determinant is the availability of a sufficient number of intact grafts in the safe donor area. Nonetheless, it is imperative for these individuals to undergo a comprehensive evaluation by a dermatologist before making decisions regarding hair transplant surgery, ensuring a well-informed approach.

How Does The Presence Of Retrograde Alopecia Impact The Donor Area For A Hair Transplant?

The presence of retrograde alopecia can significantly impact the donor area for hair transplantation. Retrograde alopecia primarily affects the sides above the ears and the nape, which are commonly used as donor areas for hair transplant procedures. Its progressive nature reduces the overall donor supply over time.

Additionally, it is strongly recommended to exclude the finer hairs in the affected scalp region from any hair transplant procedure, as they are sometimes mistakenly harvested despite their thinner caliber. These hairs are often intended for use in the frontal hairline; however, due to their miniaturization, they ultimately fail—either by not surviving the transplantation process or by failing to continue growing after the procedure due to ongoing miniaturization and eventual follicular death.

As a result, patients with retrograde alopecia may need to carefully adjust their expectations and goals regarding hair transplant procedures, taking into account the evolving nature of their condition and the potential limitations of the donor area.
