Hair Loss
Autoimmune hair loss (alopecia areata).
Alopecia areata is an autoimmune condition in which the immune system targets hair follicles, causing hair to fall out — usually in round or oval patches. It can be distressing, and support is available.

Understanding it
About alopecia areata
Alopecia areata can appear at any age, in women and men alike. It often begins with one or more smooth, coin-sized patches on the scalp or beard. In some people it extends to the whole scalp (alopecia totalis) or to all body hair (alopecia universalis).
The follicles are not destroyed, so hair can regrow — sometimes on its own, sometimes after months — but the course is unpredictable and new patches may appear.
Common causes
- The immune system attacking the hair follicles
- A genetic predisposition; it can run in families
- More common in people with other autoimmune conditions, such as thyroid disease or vitiligo
- Episodes are sometimes reported after illness or significant stress
Signs and symptoms
What you may notice.
- Round or oval smooth patches of hair loss
- Short, broken hairs at the edge of a patch
- Sudden loss in a well-defined area
- Thinning of eyebrows, eyelashes or beard
- Nail pitting or ridges in some people
Managing it
Approaches that may help.
Dermatology care
A dermatologist confirms the diagnosis and can recommend medical treatments, from topical and injected options to oral treatments for more extensive cases.
Gentle scalp care
A calm, well-cared-for scalp supports comfort, especially when patches are exposed.
Immediate coverage
When hair loss is extensive, a custom cranial prosthesis can restore a natural appearance while medical care continues.
Support
Many people find it helpful to connect with others who have alopecia; your physician can suggest local or national organizations.
When to see a physician
Please see a dermatologist for diagnosis and medical treatment. When medical care is involved, we collaborate with your physician.
