Alopecia areata (patchy hair loss)
Alopecia areata causes round, smooth bald patches, sometimes on the scalp, beard or eyebrows. It is an autoimmune condition, not an infection, and it is not contagious.

Living with it
The course is unpredictable. Many patches regrow, some return, and a few spread. Early consultation helps choose the right treatment and reduces distress.
Treatment options
Options include steroid injections into patches, topical medicines, immunotherapy, oral medicines for extensive disease, and other newer treatments where suitable. Your dermatologist will explain the benefit and side effects of each.
See a doctor if
- Round bald patches appear suddenly
- Eyebrows, beard or eyelashes are affected
- Hair loss is spreading quickly
- Nails show pitting or ridges
Alopecia areata in children
Alopecia areata can start in childhood. Children are treated gently, mostly with creams and lotions, and the doctor also checks for related conditions such as eczema or thyroid problems. Reassurance and support at school matter as much as the treatment.
Beard and eyebrow patches
Patches in the beard or eyebrows are common in men. They are treated with the same approach as scalp patches, including creams and, where suitable, small steroid injections into the patch.
Frequently asked questions
Will my hair grow back?
Often yes, though it can take months and may recur. Treatment can speed regrowth.
Is it caused by stress?
Stress may trigger flare-ups in some people, but it is not the only cause.
Is alopecia areata contagious?
No.
How long does it take for hair to regrow?
With treatment, regrowth often starts within a few months. The first hairs may be fine or white and darken over time.
Can alopecia areata come back?
Yes, new patches can appear later. Early treatment of a new patch usually works best.
Do I need blood tests?
Sometimes. The doctor may check thyroid function and other tests if your history suggests a related condition.
