Alopecia areata runs in family. If your father have same problem then U will get. With the treatment we can control it. U can send some images to me on practo direct so I can suggest some treatment.

You may be having alopecia areata. this is an autoimmune condition due to the attack of lymphocytes​ against hair roots. It results in the formation of bald patches on the scalp. It can affect any hairy area of the body also like eyebrows and  beard. It has to be treated properly for long duration until the immunity comes down. Once the immunity is controlled, hair grows back over the patches. Please contact me with photos through online consult or visit me at my clinic for accurate diagnosis and treatment.
