Welcome to HealthcareMagic forum.
Yes your child most probably is suffering from alopecia areata
Alopecia areata is an autoimmune disease
that causes round, bald patches on the head and possibly other parts of the body as well. Alopecia areata is the most common type of alopecia (or hair loss).
Children affected by alopecia areata will have random bald patches. The patches are usually small and round. Sometimes itching may occur in the area where a new bald patch is occurring.
Children with alopecia areata may also experience eczema, allergies, asthma, vitiligo or thyroid disease
The other conditions which can look similar are fungal infections but they can be easily ruled by examination by a dermatologist
There is currently no effective treatment for alopecia areata. In some cases cortisone injections may help. Also, minoxidil
and anthralin creams help some children, but not all.
So please do not worry, your doctor has most probably made the correct diagnosis and started appropriate treatment . With time it should resolve and but in rare cases it can worsen.
As of now the situation in your child doesn't seem worrisome but does need regular follow up treatment .
Hope I have answered your query.
Wishing your child a speedy recovery.
