Hello, I had a FUE (1800gr) a 1 month ago. At week 4 post op, I noticed I have flaking in front and on the entire forehead. I had SD long time ago, but in small areas. Now is much more. When I did my FUE, I haven't SD and my scalp was clear. Now I'm very afraid that my FUE will be unsuccessful. I connected my doctor, and he told me to go to a dermatologist. What is that shampoo that can cure the SD without damaging the new FUE follicles? Can SD affect the new follicles after 4 weeks post op?
