Finding a smooth, circular bald patch on your scalp is alarming. Unlike gradual thinning, alopecia areata appears suddenly — often as one or more round or oval patches where hair has completely fallen out. If this describes what you're experiencing, you're not alone.
What Is Alopecia Areata?
Alopecia areata is an autoimmune condition where the immune system mistakenly attacks hair follicles. This causes hair to fall out in patches, typically on the scalp but sometimes affecting eyebrows, eyelashes, beard, or body hair.
It affects around 2% of people at some point in their lives — that's over a million people in the UK. It can develop at any age but often first appears in childhood or young adulthood.
Recognising the Signs
- Smooth, round patches: Usually coin-sized or larger
- "Exclamation mark" hairs: Short, broken hairs that taper at the base
- Sudden onset: Patches appear within days or weeks
- No scarring: The scalp skin looks normal
- May affect nails: Pitting or ridges on fingernails
What Causes It?
The exact cause isn't fully understood, but it's autoimmune — the body's defence system attacks its own hair follicles. Factors that may contribute include:
- Genetics: Runs in families
- Other autoimmune conditions: Often seen alongside thyroid disease, vitiligo
- Stress: May trigger episodes in susceptible individuals
- Environmental factors: Viral infections may play a role
Will Hair Regrow?
In many cases, yes. About 50% of people with limited alopecia areata see regrowth within a year without treatment. The follicles aren't destroyed — they're temporarily dormant.
However, the condition can be unpredictable. Hair may regrow completely, partially, or new patches may appear. Some people experience one episode; others have recurring episodes throughout life.
Treatment Approaches
There's no cure, but several treatments can encourage regrowth:
- Topical treatments: Corticosteroids, minoxidil
- Steroid injections: Directly into affected areas
- Immunotherapy: For more extensive cases
- Light therapy: PUVA treatment
- Newer medications: JAK inhibitors showing promise
The right approach depends on the extent of hair loss, your age, and how the condition is affecting you.
The Role of Trichology
A trichologist can help by:
- Confirming the diagnosis with detailed examination
- Identifying triggers that may be worsening the condition
- Recommending scalp care to support regrowth
- Providing practical advice on camouflage and coping
- Monitoring progress over time
At Solent Trichology Clinic in Gosport, trichoscope examination reveals exactly what's happening at follicle level, helping to guide the most appropriate support.
The Bottom Line
Alopecia areata is challenging, but it's manageable — and hair often does return. Getting proper assessment and support makes the journey easier.
