In many situations, hair loss is related to factors like genetics or stress. Even hormone changes may cause hair loss. For those who have significant hair loss that is not attributed to one of these concerns, a condition called folliculitis decalvans could be to blame. This is not a common condition, but it can occur to many people, and when it does, it can create long-term, often permanent results. That includes baldness and scarring. If you think you may have this condition, be sure to reach out to your doctor for immediate help and support.
