Alopecia Totalis vs Universalis: Key Differences

Alopecia totalis vs universalis is an important distinction within the alopecia areata (AA) spectrum. Both are forms of autoimmune, non-scarring hair loss, but they differ in how extensive the hair loss is. In plain English: alopecia totalis means near-complete or complete scalp hair loss, while alopecia universalis means near-complete or complete hair loss on the scalp and body.^[1][6]

Alopecia totalis vs universalis: key differences, diagnosis, prognosis, treatment options, and practical care. — Alopecia totalis affects the scalp; alopecia universalis affects the scalp and most or all body hair. Both are severe forms within the alopecia areata spectrum.

Key points

Alopecia totalis (AT): near-complete or complete loss of scalp hair.^[1][6]
Alopecia universalis (AU): near-complete or complete loss of scalp + body hair (including brows/lashes/beard in many cases).^[1][6]
Both are usually non-scarring: follicles are often still present, so regrowth can be possible.^[5]
Severity matters: more extensive alopecia areata often has a lower chance of full spontaneous regrowth than limited patchy disease. The British Association of Dermatologists (BAD) says people who lose more than half of their hair, or all of it, have only about a 1 in 10 chance of full recovery.^[5]
Not common: only about 5–10% of people with alopecia areata progress to totalis or universalis.^[3][6]
Treatment is specialist-led: extensive AA may require dermatologist-guided systemic treatment (including newer options), not only patch-focused therapy.

What alopecia totalis vs universalis means (plain English)

Alopecia areata is an autoimmune condition where the immune system attacks hair follicles, causing hair loss. It can affect the scalp, beard, eyebrows, eyelashes, and body hair.^[1][3]

The common confusion is about the names:

Alopecia areata (patchy): one or more round or oval bald patches, usually on the scalp. This is the most common pattern.^[3]
Alopecia totalis: hair loss is limited mainly to the scalp (near-complete or complete).
Alopecia universalis: hair loss is much more extensive, involving the scalp and body hair, usually including the face, brows, and lashes.^[1][6]

Both are uncommon. Alopecia totalis is estimated to affect about 0.03% of the population, and fewer than 10% of people with alopecia areata go on to develop it. Most people with alopecia totalis first had patchy hair loss, with the most common starting point being multiple patches (5 or more).^[6]

Symptoms: what totalis and universalis look like

Alopecia totalis: all or nearly all scalp hair is lost. Eyebrows, eyelashes, and body hair may or may not be affected.^[1][6]
Alopecia universalis: in addition to the scalp, hair is lost from the face (eyebrows, eyelashes, beard) and the rest of the body.^[1][6]
The skin usually looks normal: there is typically no scale, scarring, or inflammation, although some people notice itching, burning, or tingling before or after hair falls.^[3][5]
Nail changes: pitting and ridging of the nails are seen in an estimated 10–40% of people with alopecia areata and tend to go with more severe disease.^[3]
Eyes: loss of eyelashes can cause dry or irritated eyes, especially in windy weather.^[5]
Pain and physical disability are not features: alopecia areata does not cause physical disability, but it can affect emotional well-being.^[2]

Same disease, different extent (why this matters)

AT and AU are not “different diseases” from patchy alopecia areata—they are usually considered part of the same AA spectrum. What changes is the extent of hair loss, and that often changes:

how treatment is chosen,
how quickly doctors escalate therapy,
how closely follow-up is needed, and
what supportive care (brow/lash/eye/scalp protection) becomes important.

Totalis and universalis describe extent. A different term, ophiasis, describes a pattern (a band along the back and sides of the scalp), and a person can have an extensive pattern without having totalis or universalis.

If you are still in the “patchy” stage and want the basics first, read: First-Line Alopecia Areata Treatment.

How doctors diagnose severe alopecia areata (diagnosis-first)

Doctors usually diagnose alopecia areata based on a history + scalp/skin exam, and they may examine the nails and use a handheld magnifier/dermatoscope (trichoscopy) to look more closely at hair follicles and openings.^[1][2]

Depending on the case, clinicians may also consider:

Blood tests (when another condition could be contributing or mimicking hair loss)
Scalp biopsy (especially if diagnosis is uncertain or scarring alopecia is a concern)
Exam of eyebrows/eyelashes/beard/body hair to map the full pattern
Nail check (AA can be associated with nail changes in some people)

Because AA is linked with other conditions such as thyroid disease, eczema, and other autoimmune diseases, regular check-ups with your primary care doctor are recommended.^[2]

For the full diagnostic pathway on this site, see: How Hair Loss Is Diagnosed, Blood Tests & Workup, and Scalp Biopsy.

Why diagnosis-first is still important in AT/AU

Even when hair loss is extensive, doctors still need to confirm the pattern and make sure there are no signs pointing to a different diagnosis (especially scarring conditions or infection in specific situations). Conditions that can look like alopecia areata include tinea capitis, hair-pulling (trichotillomania), traction alopecia, lupus, and secondary syphilis.^[4] The treatment strategy changes a lot depending on the diagnosis.

Prognosis & expectations (realistic, not hopeless)

Alopecia areata is unpredictable. Some people regrow hair, some relapse, and some have cycles of loss/regrowth over time. In general, the chance of spontaneous/full regrowth tends to be better when hair loss is less extensive and lower in more extensive forms such as AT/AU.^[3][5]

What the sources say about outlook:

BAD: in alopecia totalis and universalis, the likelihood of total regrowth is lower without treatment, and people who lose more than half of their hair, or all of it, have only about a 1 in 10 chance of full recovery.^[5]
DermNet is more cautious: it describes recovery as unlikely once alopecia totalis or universalis has developed.^[3] Treatments, particularly JAK inhibitors, have changed what is possible (see below), but results vary and hair loss can return when treatment stops.
Sources agree that this is not a single, fixed outcome. Regrowth can happen even after long periods without hair, but it is not guaranteed.

Important practical points:

Relapse can happen: even after regrowth, future episodes may occur.^[5]
AT/AU can still regrow: lower probability does not mean “never.”
Timeline is variable: regrowth (when it happens) may begin with fine/white hair before thickening and regaining color.^[3][5]
Mental health impact is real: severe AA can affect confidence, mood, and daily function—depression and anxiety are more common in people with alopecia areata, so support matters and is part of good care.^[2][5]

Treatment options for extensive AA (AT/AU)

There is no cure for alopecia areata, and for many people with milder disease hair grows back without treatment. Some people with severe disease choose to decline treatment and use wigs or hairpieces instead.^[2][3] Treatment is individualized based on age, severity, how fast hair loss is progressing, prior treatments, eyebrow/eyelash involvement, and medical history. For extensive alopecia areata, dermatology sources describe treatment plans that may include the following:

1) Contact immunotherapy (topical immunotherapy)

This is a dermatologist-directed treatment used for widespread alopecia areata. A chemical (usually diphenylcyclopropenone) is applied to the scalp to cause a mild allergic skin reaction. It is usually done in clinic on a repeated schedule and can take months to judge response. It is not a quick fix, and consistency with appointments matters. Side effects such as an itchy or blistering rash, enlarged lymph nodes, and loss of skin color can limit its use.^[1][3][5]

2) JAK inhibitors (specialist-guided systemic treatment)

Dermatology guidance notes that JAK inhibitors are now an important option for severe/widespread alopecia areata.^[3][4] In the United States, three JAK inhibitor tablets are FDA-approved for severe alopecia areata: baricitinib (Olumiant) and ritlecitinib (Litfulo), both approved for people aged 12 and older (baricitinib’s age range was extended in 2026), and deuruxolitinib (Leqselvi) for adults.^[3] Availability, age eligibility, and prescribing rules vary by country. In the UK, for example, ritlecitinib is NHS-funded for people aged 12 and over with severe AA, while baricitinib is licensed but not currently NHS-funded.^[5] In trials of ritlecitinib in severe alopecia areata, almost a quarter of patients reached a SALT score of 20 or less after 24 weeks, rising to over 40% after one year.^[3] Hair loss can return after stopping, and long-term safety data are still being collected.^[3]

Practical reminder: these are systemic immune-modulating medicines with boxed warnings (including serious infections, heart-related events, cancers, and blood clots). They require discussion of benefits, risks, monitoring, and follow-up, and are always a dermatologist decision.^[5]

3) Other systemic or adjunct options (case-by-case)

Depending on the patient and treatment response, dermatologists may discuss other immune-modulating treatments or adjuncts. Short courses of steroid tablets can sometimes regrow hair in moderate to severe cases, but hair loss often returns when they are stopped, and long-term use is not recommended because of side effects. Other medicines, such as methotrexate or ciclosporin, are mainly reserved for severe cases when other treatments have failed, and the evidence for them is limited.^[3][5] These choices depend heavily on age, risk profile, and access.

4) Patch-focused treatments may still be used in selected situations

For example, if there is mixed disease (patchy regrowth areas, brow involvement, or localized activity), dermatologists may still use local therapies in selected areas. But for classic extensive AT/AU, patch-only treatment is often not enough. See: Steroid Injections for Alopecia Areata.

Practical care (eyebrows, lashes, skin, scalp)

Eyebrows / eyelashes

If eyebrows or eyelashes are affected, comfort and protection matter—not just hair regrowth. Loss of lashes can lead to dry or irritated eyes, which may be worse in windy weather, and brows help keep sweat and debris away from the eyes.^[5]

Protect the eyes with glasses/sunglasses when needed
Use gentle cosmetic camouflage if desired (eyebrow pencils, tattooing or microblading, stick-on brows, false lashes)^[3][5]
Discuss specialist options for eyebrow/eyelash care (do not self-treat aggressively near the eyes). For example, a dermatologist may consider prostaglandin eye-drop medicines for eyelashes and brows when fine hairs are still present.^[5]

Scalp / skin protection

Protect exposed scalp skin from sun (hat/scarf + sunscreen when appropriate)^[5]
Reduce irritation from harsh products
Use gentle cleansing and moisturization if scalp skin feels dry/sensitive

Cosmetic and supportive options are valid care

Wigs, hairpieces, hats, scarves, stick-on brows, and cosmetic camouflage are not “giving up.” They are legitimate tools for comfort, confidence, and daily function while deciding on treatment or waiting for response. In some countries, wigs may be available through the health system; in England, for example, they can be obtained on a consultant’s prescription, usually with a financial contribution.^[5]

When to seek care sooner (red flags)

Even if AA is the suspected diagnosis, seek prompt evaluation if you have:

Rapidly spreading hair loss over days/weeks
Scalp pain, burning, tenderness, pus, crusting, or marked inflammation
Eye irritation/soreness with eyelash loss
Hair loss in a child (especially if scaling/crusting is present)
Strong emotional distress, anxiety, or low mood affecting daily life

FAQ

Is alopecia totalis the same as alopecia universalis?

No. Both are severe forms of alopecia areata, but totalis mainly refers to scalp hair loss, while universalis refers to scalp and body hair loss.

Is alopecia universalis the same as alopecia areata?

Alopecia universalis is a severe form of alopecia areata. Alopecia areata is the umbrella condition, and it ranges from a few small patches to complete loss of hair on the whole body.^[1][3]

Are alopecia totalis and universalis scarring hair loss?

They are usually considered non-scarring alopecia (follicles are generally preserved), which is why regrowth can still be possible.^[5]

Can alopecia areata turn into totalis or universalis?

Sometimes, but not often. Only about 5–10% of people with alopecia areata progress to alopecia totalis or universalis.^[3][6] Most people with patchy alopecia areata never reach that stage.

Can hair grow back in alopecia totalis or universalis?

Yes, regrowth can happen, but outcomes are unpredictable and the chance of full spontaneous regrowth is generally lower than in limited patchy AA.^[5] Treatments such as JAK inhibitors have helped some people regrow hair, including eyebrows and lashes, but hair loss can return when treatment is stopped.^[3]

Is there a cure for alopecia universalis?

There is currently no cure for alopecia areata, including totalis and universalis. Treatments can induce hair growth in some people, but they do not change the underlying course of the disease.^[3][5]

What are the symptoms of alopecia totalis and universalis?

In totalis, all or almost all scalp hair is lost. In universalis, hair is also lost from the face and body, including eyebrows and eyelashes. The skin usually looks normal, and some people have nail pitting or ridging.^[1][3] See the symptoms section above.

Can alopecia totalis turn into universalis?

Some people who lose all of their scalp hair later lose body hair as well, but the sources reviewed here do not give a reliable percentage for this step. Only about 5–10% of people with alopecia areata progress to totalis or universalis in the first place.^[3][6] A dermatologist can explain what to expect for your pattern.

How does alopecia totalis or universalis affect daily life?

Alopecia areata does not cause physical disability, but depression and anxiety are more common in people with the condition, and the impact on confidence, relationships, and work can be significant.^[2][3][5] Professional counselling and patient support groups can help, and camouflage options (wigs, hairpieces, stick-on brows) are valid care.^[3] If low mood is affecting your daily life, tell your doctor.

Do I need a dermatologist?

For extensive hair loss (especially suspected AT/AU), dermatologist evaluation is strongly recommended because treatment selection, monitoring, and eye/scalp protection may become more complex.

Should I wait or start treatment immediately?

That depends on age, extent, speed of progression, affected areas (scalp only vs brows/lashes/body hair), and your goals. A dermatologist can help decide whether watchful monitoring, local therapy, or systemic treatment is most appropriate.
