What Is Alopecia Areata in Children?
Alopecia areata usually appears as sudden, round and clearly defined bald spots on the scalp. It is caused by an overreaction of the immune system, which temporarily attacks the hair roots.
The condition is not contagious, but it can be very upsetting for children and their families.
A specialist examination is especially important when:
- Sudden round bald patches appear on the scalp
- Hair falls out in patches or small clumps
- Bald areas grow or new ones develop
- Your child has had alopecia areata before and it’s coming back
- You are unsure whether it’s a hair disorder

What Happens During the Diagnosis and Treatment of Bald Patches in Children?
At Derma Medical Clinic, we thoroughly investigate hair loss: A specialized children’s dermatologist carefully examines the affected areas using a special magnifying device (dermatoscope) to closely inspect the hair roots and scalp.
Depending on the findings, we may recommend additional blood tests to rule out possible causes such as infections or nutritional deficiencies.
What does the treatment involve?
The treatment is tailored to your child’s diagnosis. Often, anti-inflammatory lotions or creams are applied directly to the bald spots.
In addition, parents receive practical advice on gentle scalp care, such as the use of mild shampoos and specific routines to help soothe the skin.
How Is Alopecia Areata Examined in Children?
Important: The examination is done calmly and at your child’s pace. We only proceed with tests or treatments if your child feels comfortable. There is no pressure – instead, we respond with patience and experience to your child’s feelings and mood.

The exact cause is not fully understood. It is thought to be an immune system overreaction that targets the hair roots. Stress, infections, or other triggers may also play a role.
What treatment options are available for bald spots in children?
Depending on the child’s age and the severity, we may use anti-inflammatory lotions, immune-modulating treatments, or supporting hair care. The goal is to stop inflammation and support hair regrowth.

The typical sign is sudden, sharply defined, round bald patches on the scalp. The skin usually looks normal, with no redness or scaling.
Do the hairs grow back after an episode?
In many cases, the hair grows back on its own after a few months. However, relapses may occur, as the course of the condition varies from child to child.
How long does it take for the hair to grow back?
Hair regrowth often begins within 3 to 6 months. Full recovery may take longer, depending on how severe the hair loss was.
When should I take my child to a dermatologist?
If bald patches appear suddenly or hair loss increases rapidly, it’s best to see a dermatologist. They can find the cause and suggest the right treatment.
What can support the treatment?
Gentle hair care with mild products, a stress-free environment, and good scalp care can support the treatment. Important: Never start treatment without medical advice.
