Hello all. I'm very new to this forum but I remember seeing a friend use it so I'm giving it a try. I'm a 22 year old male. For some reason I feel as if I'm losing my hair or going bald. The reason for this is due to the fact that when i brush my hair I notice it is very thin on the left side of my head along hair line (Pictured). My girlfriend insists I'm going crazy and says it is probably just baby hair which I've never heard it. It is in some pictures of me when I was younger but I am curious as to what you guys thought and what my problem may be if any. Pictures attached.
