How is cradle cap diagnosed?

Cradle cap is usually diagnosed based on physical examination of the child. The rash involved with cradle cap is unique, and can usually be diagnosed using a physical examination.

What is the treatment for cradle cap?

The specific treatment for cradle cap will be determined based on:

  • The child's age, overall health, and medical history
  • Extent of the condition
  • The child's tolerance for specific medications, procedures, or therapies
  • Expectations for the course of the condition
  • Parent’s opinion or preference

Although the condition responds to treatment, it may recur. Treatment is usually effective in helping symptoms and may include:

  • Special shampoo, as prescribed by a physician
  • Corticosteroid cream or lotion
