About a month ago I noticed two spots of hair not growning on my face and then a week later another on my cheek. Now I have a small spot on the bad of my head missing hair also. My girlfriend thinks it’s because of stress. What do you think it is?
You need to see a good dermatologist. Amongst the things that the doctor will evaluate is the possibility of alopecia areata or ringworm (the two most common causes of what you are talking about). It is not reasonable to expect me to make a diagnosis over the internet from a few lines of description.
