Abstract: A concentrator and a hair dryer including a concentrator are provided. The concentrator may include an outer case forming an exterior of the concentrator and provided with first and second flow paths thereinside to enable gas discharged from a gas discharge of the hair dryer to flow and a flow path selector a position of which is variable within the outer case, the first flow path being provided between the flow path selector and the outer case, the second flow path being provided within the flow path selector. The concentrator may be configured to externally discharge the gas discharged from the gas discharge along either the first flow path or the second flow path depending on the position of the flow path selector. Accordingly, a user may select the first flow path or the second flow path for convenience while using a single concentrator.
