A local dermatologist is a doctor who has taken additional training in treating diseases and conditions of the skin, hair and nails. A local dermatologist may treat conditions such as skin cancer, psoriasis, eczema, dermatitis, hair loss, nail fungus and moles. If your local family physician believes that you would benefit from seeing a local dermatologist for a problem with your Atopic Dermatitis   skin, hair or nails, they will refer you to a specialist in your area. Some local dermatologists perform cosmetic procedures such as dermal fillers and Botox.
