<p>Device 3.2 with an automatic switch-off mechanism and a steam hood 4 for the steam treatment of the scalp hair 1 of a person 2. A sensor 7 for the recording of the ammonia emission values Vx1...Vxn is located inside the steam hood 4. The ammonia sensor 7 is connected with a measurement unit 8 for measurement of the ammonia emission values Vx1...Vxn, wherein the measurement unit 8 is connected with a control unit 6. The device 3.2 or, respectively, the steam hood 4 has an extraction unit 5 that is controllable by the control unit 6 and extracts the ambient air in the neighborhood of an (upper) forehead region (A) or an eye/nose region (B) of person (2). At the start to of the steam treatment the extraction unit 5 is automatically activated by the control unit 6. By convergence with or undershooting of a pre-set ammonia emission value V1 the extraction unit 5 is deactivated automatically. Preferably an electric fan 10 that is simple to control (in on/off function and fan performance) and is very cost-effective (Fig. 5) is used as extraction unit 5, which can be arranged compactly inside or on the steam hood 4.</p> |
