Hi That can be a condition of patchy hairloss called Alopecia Areata, It starts with patches of hairloss over scalp, eye brow, beard and mustache(in adults), gradually these individual patches join together to form a bigger patch. There are different types of Alopecia areata, depending on the nature and extent of the disease. cause: exact cause is not known, It is found to be associated with autoimmunity. It can be treated with Homeopathy safely with oral medications and external application, which depends on individaul case. I suggest you not to go for steroidal injections, beware of their side-effects. call me for any further quieries. Homeopathy Human friendly.
