Flannel rash is a skin condition characterized by small pink patches topped with oily scales. These patches often expand into larger oval shapes that typically clear in the center, creating a ring-like appearance. Itching isn’t frequently associated with this condition. There’s a notable link between this rash and scalp dandruff; some specialists believe the dandruff flakes might cause the rash on other parts of the body. Therefore, to effectively treat the rash, it’s essential to address the dandruff simultaneously.
