Eczema : Eczema can affect the skin near the scalp as well. Use unscented soaps and gentle shampoos such as the earth science line from whole foods. As for the discoloration, any rash can cause post-inflammatory pigmentary changes and most of these will fade over the course of a few months. See a dermatologist for appropriate prescriptions to treat the rashes and keep them under control.
