Hair loss after coming off birth control

I was on microgynon for 8 years without any issues. I stopped two years ago and after two months I started to have a lot of hair shedding. This hasn't stopped ever since. My dermatologist recommends to start birth control again. I also have oily skin. We did a lot of testing (hormones, thyroid, vitamins, minerals, gut test etc) but everything if perfectly fine. I have a healthy diet and no stress in life. Anyone has any experience?
