Understanding Alopecia Universalis: Causes, Symptoms, and Treatment at NIS
Alopecia Universalis is a condition marked by complete hair loss not only on the scalp but also across the entire body. Unlike other forms of alopecia that primarily affect scalp hair, Alopecia Universalis leads to hair loss from all hair-bearing regions. It’s considered a severe progression of alopecia areata, where small, patchy hair loss occurs on the scalp. About 1 to 2% of individuals with alopecia areata advance to Alopecia Universalis. While the precise causes remain elusive, it’s believed to stem from an autoimmune response, where the body’s immune system mistakenly attacks healthy hair follicles. Some experts also suggest involvement of genetic and environmental factors. Since the hair loss in Alopecia Universalis is non-scarring, there’s potential for hair regrowth in certain cases. This article delves into the clinical features, causes, and available treatments for Alopecia Universalis.
What is Alopecia Universalis?
Alopecia Universalis manifests as complete hair loss on both the scalp and body, representing an extreme form of alopecia areata. This condition progresses from alopecia areata, which causes small, round patches of hair loss on the scalp. As it advances, alopecia areata may evolve into alopecia totalis, resulting in total scalp hair loss, or Alopecia Universalis, leading to hair loss from all hair-bearing areas, including the face, pubic region, underarms, chest, hands, and legs. The underlying mechanism involves inflammation-mediated damage to hair follicles, with inflammatory markers like pathogenic T-cells and cytokines infiltrating the hair follicle bulb. Complete body hair loss can trigger psychological distress, contributing to a higher prevalence of mood, anxiety, and depressive disorders among individuals with Alopecia Universalis.
Alopecia Universalis can affect individuals of all ages, typically appearing before the age of 30 years.
Causes of Alopecia Universalis
The precise cause of Alopecia Universalis remains elusive, but its association with alopecia areata suggests a strong autoimmune component. This condition often coexists with other autoimmune disorders like vitiligo, lichen planus, morphea, atopic dermatitis, and diabetes mellitus, indicating an immune system attack on healthy hair follicles. Interestingly, the antigen targeted in Alopecia Universalis appears to be specific to hair follicles. While autoimmune factors play a significant role, genetic inheritance, environmental triggers, and factors like psychologic stress, anemia, parasitic infestations, and thyroid disorders may also contribute to the development of alopecia areata, which can progress to Alopecia Universalis.
Additionally, Alopecia Universalis may arise as an adverse effect of medical treatments like chemotherapy or multiple sclerosis therapy.
Common causes of Alopecia Universalis include:
-
- Autoimmune response targeting healthy hair follicles
- Genetic predisposition with potential inheritance
- Environmental and psychological triggers such as trauma, viral infections, or stress
- Co-occurrence with other autoimmune disorders like dermatitis, vitiligo, or lichen planus
- Adverse effects following multiple sclerosis treatment
Symptoms of Alopecia Universalis
The hallmark symptom of Alopecia Universalis is complete scalp hair loss, accompanied by hair loss across the entire body, setting it apart from other forms of alopecia. Additional symptoms may include scalp itching or burning, nail changes, and psychological disturbances.
Common symptoms of Alopecia Universalis include:
-
- Complete loss of scalp hair
- Total baldness
- Absence of eyebrows and eyelashes
- Absence of body hair
- Nail changes such as spaced pits on nail surfaces
Can Alopecia Universalis be Inherited?
Alopecia Universalis is believed to result from a combination of autoimmune, genetic, and environmental factors. While genetic predisposition may play a role and some individuals with Alopecia Universalis may have affected family members, it’s not considered directly heritable.
Diagnosing Alopecia Universalis
Diagnosing Alopecia Universalis involves a thorough examination of the scalp and body, accompanied by a review of medical history, as it often coexists with other autoimmune conditions. The characteristic symptom of total baldness alongside full body hair loss serves as a clear indicator of the condition. In some cases, skin histopathologic findings may be necessary to confirm the diagnosis, revealing peribulbar lymphocytic inflammation dominated by T lymphocytes. Blood tests may also be conducted to detect the presence of autoimmune disorders.
Treatments for Alopecia Universalis
Treating Alopecia Universalis necessitates addressing both its physical and psychological symptoms, although available treatments have shown varying efficacy and may pose adverse effects. Consequently, managing Alopecia Universalis remains challenging. However, several treatment options may be considered:
-
- Topical corticosteroids
- Immunotherapy
- Systemic corticosteroids
- Immunosuppressants
- Psoralen plus ultraviolet phototherapy
Given the psychological impact of complete baldness, wearing a hair wig offers a practical solution. Some specialized hair clinics also offer customized hair systems tailored to individual preferences for a natural appearance.
Prognosis of Alopecia Universalis
The prognosis of Alopecia Universalis is uncertain, with outcomes varying widely among individuals. While spontaneous hair regrowth may occur without treatment in some cases, others may not experience hair regrowth despite extensive treatment. Full recovery with hair regrowth is observed in only about 10% of patients. Given the psychological toll of complete scalp and body hair loss, seeking support through support groups or counseling can aid in coping with the condition.
Complications of Alopecia Universalis
Complications associated with Alopecia Universalis stem from its autoimmune origin and the complexity of treating alopecia areata. Despite treatment, some individuals may not experience hair regrowth, and the chances of recovery are unpredictable, with only a minority achieving full recovery.
Is There a Cure for Alopecia Universalis?
At present, there’s no definitive cure for Alopecia Universalis. However, certain therapies, such as immunosuppressants, oral and topical corticosteroids, and phototherapy, show promise in managing the condition.
Fast Facts on Alopecia Universalis
-
- Alopecia Universalis is primarily an autoimmune disorder, though genetic and environmental factors may also play a role.
- It results in complete loss of scalp and body hair.
- It represents an advanced stage of alopecia areata, characterized by patchy hair loss on the scalp.
- Alopecia Universalis can lead to mood disorders, anxiety, depression, and other psychological disturbances.

Statistics of Alopecia Universalis
Limited epidemiological data are available on the incidence of Alopecia Universalis. According to European data, approximately 1 in 4000 individuals develops Alopecia Universalis. Some studies suggest that 7% to 25% of individuals with alopecia areata progress to alopecia totalis or Alopecia Universalis.
