A hair dryer as a hair care device includes heat application unit (30), component generation unit (40), part detection unit (64), and controller (80). Heat application unit (30) applies heat to a user's hair. Component generation unit (40) generates a component acting on hair. Part detection unit (64) detects at least a part of hair. Controller (80) estimates a part to which heat or the component is applied based on an output of part detection unit (64), and adjusts amount of heat set in heat application unit (30) or a component amount set in component generation unit (40) for each part.
