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.

Hair treatment method

System for treating a head of hair, including a pipe for circulating a liquid, a device for feeding the pipe with water, at least one source of product, the product (P) comprising one or more surfactants, a device for injecting product into the pipe to form a treatment solution comprising one or more surfactants in a content ranging from 0.35% to 1.5% by weight of surfactant(s) relative to the total weight of the treatment solution, a dispensing device for delivering the treatment solution onto the head of hair (B) with a flow rate of between 0.5 and 5 L/min, better still between 0.8 and 3 L/min.

Hair treatment system

A system for washing the hair, including a first reservoir for receiving a first liquid (L) constituted by or comprising water, a second reservoir for receiving a second liquid (L) 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 (L), 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.
