Yes you might be suferring from Seborheic Dermatitis, I know because I suffer from this condition as well. I would suggest you use Nizoral shampoo that helps keep everything under control and for the red patches a hydracortizone cream. Yes and it could spread to your face like it did to me. If you use over the counter products I suggested or any other and they dont work for you the I suggest you go see a dermatologist and they can prescribe you something better and much stronger. Good Luck.....
