Alopecia Areata: What It Is and What Actually Helps

TL;DR:

• Alopecia areata is an autoimmune condition — the immune system attacks hair follicles. It is not caused by stress alone, poor diet, or poor hygiene
• The hallmark sign is smooth, round bald patches that appear suddenly on the scalp. The skin in the affected area looks completely normal
• The follicle remains alive and capable of producing hair — which is why spontaneous regrowth is possible
• Standard hair loss shampoos and serums are not effective treatments for alopecia areata — it requires medical assessment and treatment
• New JAK inhibitor medications (approved 2023) have shown significant results for moderate to severe cases

Alopecia areata is not the same as regular hair loss. If you've noticed one or more smooth, round bald patches appearing suddenly on your scalp or elsewhere on your body, you may be dealing with an autoimmune condition that needs to be understood and treated differently from other types of hair loss.

A note on expertise: Alopecia areata is a medical condition requiring diagnosis and treatment by a dermatologist. This article explains what it is and what options exist. Our stylists can support clients experiencing alopecia areata with sensitive styling advice and scalp care recommendations, and we will always refer you to a specialist when appropriate.

01 — What Alopecia Areata Is

Alopecia areata is an autoimmune condition in which the immune system mistakenly attacks hair follicles, causing them to stop producing hair. It's not contagious, it's not caused by stress alone, and it's not a sign of poor health or hygiene. It affects approximately 2% of the global population at some point in their lives, making it one of the most common autoimmune conditions in the world. It can affect anyone, at any age, regardless of gender or ethnicity.

Crucially: alopecia areata does not scar the follicle. The follicle remains alive and capable of producing hair — which is why spontaneous regrowth is possible.

02 — What It Looks Like

The most recognisable sign is one or more smooth, round or oval bald patches on the scalp. The skin in the affected area typically looks completely normal — no redness, no scaling, no scarring. The patches can appear suddenly, sometimes overnight. Other signs include exclamation mark hairs (short hairs narrower at the base, found at the edges of patches), nail changes (pitting, ridging, or brittleness), and hair loss in other areas like eyebrows, eyelashes, beard, or body hair. In more extensive cases: alopecia totalis (complete scalp hair loss) or alopecia universalis (complete loss of all body hair).

03 — What Triggers It

The exact cause isn't fully understood, but it involves a combination of genetic predisposition and immune system dysfunction. Triggers that can initiate or worsen flares include significant emotional or physical stress, illness or infection, hormonal changes, and other autoimmune conditions — thyroid disease, vitiligo, and type 1 diabetes are more common in people with alopecia areata. Stress can trigger flares but doesn't cause the condition — the autoimmune predisposition is the underlying driver.

04 — Will the Hair Grow Back?

In many cases, yes — but it's unpredictable. Around 50% of people with mild alopecia areata (one or a few patches) experience spontaneous regrowth within 12 months, even without treatment. However, the condition is chronic and relapsing — patches can return, and in some people the condition progresses. People with more extensive loss, longer-duration patches, or a family history of alopecia areata tend to have a less predictable prognosis.

05 — What Treatments Actually Help

Alopecia areata requires medical treatment guided by a dermatologist. Corticosteroid injections are the most common first-line treatment for patchy alopecia areata — injected directly into the bald patches to suppress the local immune response. Many people see regrowth within 4 to 8 weeks. Topical corticosteroids are less effective than injections but useful for mild cases. Minoxidil doesn't address the autoimmune cause but can help stimulate regrowth in follicles that are still active. Often used alongside corticosteroid treatment. JAK inhibitors (baricitinib, ritlecitinib) — a newer class of oral medications that have shown significant results in clinical trials. Ritlecitinib received FDA approval in 2023 specifically for alopecia areata. Prescription medications with potential side effects — discuss with a dermatologist. Important: standard hair loss shampoos and serums are not effective treatments for alopecia areata. They can support scalp health, but they don't address the autoimmune mechanism driving the condition.

06 — Living With Alopecia Areata

Alopecia areata can have a significant emotional impact. The unpredictability — not knowing if patches will grow back or spread — is genuinely difficult to live with. Practical support includes scalp micropigmentation or hairpieces for cosmetic coverage, support groups and communities (Alopecia SA is a South African resource), and psychological support where the condition is affecting mental health.

"We work sensitively with clients who have alopecia areata," says Debbie at the Waterfront. "Styling, covering patches, looking at what's appropriate for the current stage of the condition. We can't treat the autoimmune cause — that's a dermatologist's job — but we can absolutely support confidence and scalp comfort during treatment. Those conversations matter."

Frequently Asked Questions

Is alopecia areata permanent?

Not necessarily. The follicles remain alive and capable of producing hair. Many people experience spontaneous regrowth, though the condition can relapse. More extensive cases have a less predictable outlook.

What triggers alopecia areata?

Stress, illness, hormonal changes, and other autoimmune conditions can trigger or worsen flares. However, the underlying predisposition is genetic — triggers don't cause the condition, they can activate it in people who are susceptible.

Is alopecia areata the same as alopecia?

No — alopecia is a broad term for any type of hair loss. Alopecia areata is a specific autoimmune condition causing patchy loss. Other types include androgenetic alopecia (genetic pattern loss), traction alopecia (from tension), and telogen effluvium (stress-related shedding).

Can stress cause alopecia areata?

Stress can trigger flares in people who are genetically predisposed, but stress alone doesn't cause the condition. The autoimmune mechanism is the underlying driver.
