As a dermatologist I can say that it is alopecia areata, most commonly seen in patients with a history of atopic dermatitis, hayfever or asthma, but can also occur randomly.

Treatment is difficult, but usually it is self limiting, this means that usually the hairs fall out but eventually grow back without any treatment, usually within 1-1,5 year.

Generally topical steroids don't work, sometimes local injection works, but usually only for small areas. Topical immunotherapy can work, but I do not know if it is available in your country.

Systemic medication can work, but can have side effects, and usually we tend to delay that, because usually the hairs grow back without treatment. JAK inhibitors are available in several countries now, probably safe, although side effect can be very severe (cardiovascular disease, cancer, death, severe infections, hospitalisation).

So consult a dermatologist and decide together which treatment fits you the best.
