Abstract: A system for washing the hair, including a first reservoir for receiving a first liquid (L1) constituted by or comprising water, a second reservoir for receiving a second liquid (L2) including a treatment product diluted in water in an amount of less than or equal to 2.5% by weight relative to the total weight of the second liquid (L2), a shower head with a supply rate of between 0.3 and 5 L/min, configured to deliver a jet of droplets onto the hair. The shower head is further supplied with liquid, taken exclusively from one or other of the reservoirs, with an overpressure.

Abstract: A hair treatment method, including the step of spraying onto the hair a composition for changing the form of the hair, notably a permanent-waving or curl-reducing composition, using a device, called a low flowrate device, comprising at least two nozzles oriented such that their respective jets collide, these nozzles being supplied with said composition at pressure, the total flowrate of composition delivered by the nozzles being between 0.1 and 3 L/min, preferably between 0.2 and 2 L/min, and even more preferably between 0.3 and 1 L/min.
