There are many ways that people can lose their hair. At RHRLI, we often deal with androgenetic alopecia, better known as male or female pattern hair loss. It’s a condition that is related to a hormone called dihydrotestosterone (DHT). DHT causes hair follicles to shrink, resulting in a pattern of hair loss. There are other medical conditions that cause hair loss, but not every cause of hair loss is medical. There is a condition that can lead you to lose hair in bunches that’s psychological. It’s called trichotillomania and it often requires help from both medical and mental health professionals.
