There are many different causes of new onset hair loss and I would recommend that you make an appointment with either your primary care doctor
or your dermatologist
to discuss the issue.
By far, the most common cause of the type of hair loss you are describing - small little round spots of hair loss without any clear trigger - is a condition known as alopecia areata. Most cases of alopecia areata have no known cause and, fortunately, they often do improve or spontaneously resolve on their own. However, some cases, especially cases that are cosmetically important, do require treatment. The first line treatment for alopecia areata is usually injections of steroids into the affected area, something your doctor can do for you.
When you go to see your doctor, they will examine the areas of hair loss closely for any signs of redness, flaking, or inflammation. One of the key features of alopecia areata is that these signs are absent. If any inflammation is present, then the hair loss is much more likely to be from a different cause, such as a fungal infection, eczema
, a skin allergy, etc. If your doctor detects signs of inflammation, then the treatments will obviously be different.
