What is Alopecia Universalis?

Alopecia universalis (AU) is a rare and severe form of alopecia areata that involves complete loss of hair on the face, scalp, and body [1]. It is an autoimmune disease that causes complete hair loss on the scalp and the body [4].

Characteristics of Alopecia Universalis

• Complete loss of hair on the scalp as well as other parts of the body [5]
• Hair loss affects the entire body, including eyebrows and eyelashes [7]
• Scalp is one of the most commonly affected areas, followed by beard, eyebrows, eyelashes, and other parts of the body [7]

Causes and Symptoms

Alopecia universalis is thought to be an immune system disorder where healthy hair follicles are attacked by the body's immune system [6]. The symptoms include complete loss of hair on the scalp and body, which can be emotionally distressing for those affected.

Symptoms of Alopecia Universalis

Alopecia universalis (AU) is a rare and severe form of alopecia areata, characterized by the complete loss of hair on the scalp, face, and body. The symptoms of AU can vary from person to person, but some common signs include:

• Complete baldness: Loss of all hair on the scalp, including the eyebrows, eyelashes, beard, and body hair.
• Hair loss on the face: Bald patches or complete loss of facial hair, including the beard, mustache, and eyebrows.
• Body hair loss: Complete loss of body hair, including the arms, legs, and torso.

These symptoms can be distressing for those affected by AU. It's essential to consult a healthcare professional for proper diagnosis and treatment.

Early signs of alopecia universalis

In some cases, people with AU may experience early signs similar to those of alopecia areata, such as:

• Small patches of hair loss: Patches of hair loss on the scalp or body.
• Hair thinning: Gradual thinning of hair on the scalp or body.

If you're experiencing any of these symptoms, it's crucial to consult a healthcare professional for proper evaluation and treatment.

Diagnosing Alopecia Universalis

Alopecia universalis, also known as complete baldness, is a rare and severe form of alopecia areata that affects the entire body. Diagnosing this condition requires careful examination of scalp skin and head.

• Scalp Examination: Doctors can usually diagnose AU upon observing the pattern of hair loss. The signs of AU are distinct, with patients experiencing complete baldness on their scalp, eyebrows, beard, and other areas of the body [8].
• Medical History: A trichologist may ask for a complete medical history as Alopecia Universalis is often associated with autoimmune diseases such as thyroid disorders or vitiligo.
• Blood Tests: While blood tests can't confirm AU, they can help rule out other conditions that may be causing hair loss [5].
• Scalp Biopsy: A scalp biopsy (the gold standard) can be used for a more definitive diagnosis. Scalp biopsies can be vertically or horizontally oriented and can provide valuable information about the condition of the hair follicles [3].

It's essential to note that diagnosing AU requires a comprehensive evaluation by a dermatologist or trichologist, as this condition can have various presentations and may require specialized testing.

Treatment Options for Alopecia Universalis

Alopecia universalis, also known as complete baldness, is a condition where all body hair, including eyebrows, eyelashes, facial hair, and scalp hair, falls out. While there are various treatment options available, the most effective ones often involve a combination of medications and therapies.

Topical Therapies

• Topical corticosteroids have been used to treat alopecia universalis, but their effectiveness is limited [1].
• Minoxidil, a topical medication, has shown promising results in treating alopecia areata, including universalis, when combined with systemic methotrexate and corticosteroids [2].

Immunotherapy

• Topical immunotherapy, also known as contact immunotherapy, aims to desensitize the immune system to hair follicles, thereby stopping the attack that causes alopecia universalis [3].
• This treatment is typically performed and prescribed by dermatologists and can be uncomfortable, causing redness and rash where it is applied [4].

Systemic Therapies

• A combination of low-dose prednisone and methotrexate has been shown to induce complete hair regrowth in 31% of patients with alopecia universalis or alopecia areata [5].
• This treatment option may be effective for some individuals, but it is essential to follow a treatment plan as outlined by a dermatologist and discuss any new therapies that come along [6].

Other Treatment Options

• Researchers have been exploring other treatment options, including immunosuppressants and management strategies, to improve the outcomes of patients with alopecia universalis [7].
• A comprehensive review of existing literature on the treatment of alopecia areata highlights the need for further research into effective management strategies [8].

In conclusion, while there is no cure for alopecia universalis, various treatment options are available, including topical therapies, immunotherapy, systemic therapies, and other management strategies. It is essential to consult a dermatologist to determine the best course of treatment for individual cases.

Understanding Differential Diagnosis in Alopecia Universalis

Alopecia universalis, also known as complete hair loss, can be a challenging condition to diagnose due to its rarity and similarity with other forms of alopecia. A differential diagnosis is a process used by healthcare professionals to rule out other possible causes of a condition before making a definitive diagnosis.

Possible Causes of Alopecia Universalis

According to medical literature [1], the following conditions are considered in the differential diagnosis for alopecia universalis:

• Androgenetic Alopecia: This is the most common form of hair loss, characterized by thinning and eventual balding on the scalp. However, it does not typically affect body hair.
• Brodq Pseudopelade: A rare condition that causes patchy hair loss on the scalp.
• Pediatric Syphilis: A bacterial infection that can cause a range of symptoms, including hair loss in children.
• Telogen Effluvium: A condition characterized by excessive shedding of hair due to hormonal changes or stress.
• Tinea Capitis: A fungal infection of the scalp that can cause hair loss and other symptoms.
• Trichotillomania: A psychological disorder characterized by compulsive hair pulling.

Key Considerations in Differential Diagnosis

When diagnosing alopecia universalis, healthcare professionals consider several factors, including:

• Age and sex: Alopecia universalis is more common in young adults and children [2].
• Family history: A family history of autoimmune disorders or other forms of alopecia may be relevant.
• Physical examination: A thorough examination of the scalp and body hair is essential to rule out other conditions.
