My non-scientific definition is a hormonal imbalance that may produce unwanted facial hair in women. As an electrologist, a bulk of my clientele are women who either have a confirmed case of PCOS or a suspected case. Often times I'm seeing women with course facial hair on the upper lip and/or chin area. In African American women, I'm also seeing scarring or thickening of skin as well as pigmentation due to constant plucking/tweezing.
So how do we solve this? Well, if you made it to me, you have already started in the right direction. The next step would be to consult with your primary care provider and/or an Endocrinologist. I would also suggest a nutritionist to help form healthy eating habits. People underestimate the difference a healthy diet can make.
In addition, there is also a site dedicated to helping point a spotlight on PCOS. I've provided the link below. Helping individuals achieve a hair free existence as well as bring back self-confidence is a mission of mine. As I stated in the "About Me" section, at the heart of it all I'm a nerd and so I'm constantly researching on issues/subject matters that are important to not only my clients but further my understanding of hair and skin concerns.
