If skin, hair, or nail symptoms are not responding to home treatment, it may be time to seek professional attention. If concerns are cosmetic, a person can seek out a specialized cosmetic dermatologist. It is important for people to discuss any upcoming dermatological treatments with their insurance providers, who often do not fund cosmetic procedures. Be sure to obtain copies of any medical reports, consultation notes, and diagnostic test results to assure the insurer of the medical necessity of the treatment.
