1. A device for spraying a cosmetic or dermatological composition, comprising a casing suitable for handling by a user to spray the composition onto skin or onto other human keratinous materials, and further comprising: a container containing the composition for spraying;an ultrasound spray head including a sonotrode;an airflow generator for creating a stream of air for entraining a spray of composition particles atomized by the spray head;a conditioning device for modifying a temperature of the stream of air, the conditioning device being placed upstream from the airflow generator and configured to be switched on simultaneously with the airflow generator; anda pump feeding the sonotrode with the composition. 2. A device according to claim 1, wherein the conditioning device enables the temperature of the stream of air to be raised or lowered, and wherein the spray head is located downstream from the conditioning device. 3. A device according to claim 1, wherein the spray head, the airflow generator, and the conditioning device are in alignment. 4. A device according to claim 1, wherein the device is arranged to raise the temperature of the stream of air to more than 30° C. 5. A device according to claim 1, wherein the device is arranged to raise the temperature of the stream of air to more than 35° C. 6. A device according to claim 1, wherein the temperature of the stream or air is less than or equal to 40° C. 7. A device according to claim 1, wherein said airflow generator comprises a fan. 8. A device according to claim 1, wherein the conditioning device includes a heater device having a heater resistance. 9. A device according to claim 1, wherein a flow rate of the stream of air ranges from 4 m3/h to 7 m3/h. 10. A device according to claim 1, the composition being at least one of a makeup composition, a self-tanning agent, a composition including a hair agent, and a sunscreen composition. 11. A device according to claim 10, the composition being a foundation. 12. A method of cosmetically treating human keratinous materials, wherein a composition is sprayed and entrained towards the materials to be treated by a stream of hot or cold air by a device as defined in claim 1. 13. A method according to claim 12, the composition being a foundation sprayed onto skin. 14. A method according to claim 12, the composition being a hair agent sprayed onto hair. 15. A method according to claim 12, wherein a flow rate of the composition sprayed ranges from 0.5 g/min to 10 g/min. 16. A method according to claim 12, wherein a mean size of the particles of composition ranges from 20 μm to 30 μm. 17. A method according to claim 12, wherein a temperature of the stream of air ranges from 30° C. to 40° C. 18. A method according to claim 12, the method comprising the following steps and the composition being atomized by a sonotrode: i) putting a fan into operation to create a stream of air for entraining particles of composition,ii) after a predefined delay, setting the sonotrode into vibration by a transducer, andiii) after another delay setting a pump into operation for feeding the sonotrode with composition. 19. A device for spraying a cosmetic or dermatological composition chosen from at least one of a makeup composition, a self-tanning agent, a composition including a hair agent, and a sunscreen composition, the device comprising a casing suitable for handling by a user to spray the composition onto skin or onto other human keratinous materials, and further comprising: a container containing the composition for spraying;an ultrasound spray head including a sonotrode;an airflow generator for entraining a spray of composition particles atomized by the spray head; anda heater device arranged to raise a temperature of an outgoing stream of air from the spray head to more than 30° C. for modifying the temperature of the outgoing stream of air; anda pump feeding the sonotrode with the composition. 20. A device for spraying a cosmetic or dermatological composition chosen from at least one of a makeup composition, a self-tanning agent, a composition including a hair agent, and a sunscreen composition, the device comprising a casing suitable for handling by a user to spray the composition onto skin or onto other human keratinous materials, and further comprising: a container containing the composition for spraying;an ultrasound spray head including a sonotrode;an airflow generator for entraining a spray of composition particles atomized by the spray head; anda conditioning device for modifying a temperature of an outgoing stream of air from the spray head;the device being arranged in such a manner as to enable the user to select between an operation in which the air blown by the device is heated, and an operation in which it is not heated; anda pump feeding the sonotrode with the composition.
