Abstract
A method of treating hair more precisely including providing a hair treatment composition in a foam dispenser, dispensing the hair treatment composition directly onto the hair as a foam, leaving the foam on the hair, and rinsing the foam from the hair. The foam dispenser includes a reservoir for holding the hair treatment composition, an extended nozzle connected to the reservoir, and one or more nozzle orifices. The one or more nozzle orifices has a total orifice area of from about 5 mm2 to about 80 mm2. The extended nozzle has a protrusion length of from about 20 mm to about 125 mm. The foam has a specific volume of from about 4 ml/g to about 20 ml/g.
Claims11
A method of treating hair more precisely, the method comprising:
- a. providing or obtaining a hair treatment composition in a foam dispenser, wherein the foam dispenser comprises:
- i. a reservoir for holding the hair treatment composition;
- ii. an extended nozzle directly coupled to the reservoir;
- wherein the extended nozzle comprises one or more nozzle orifices disposed therein that are offset from the distal-most end of the extended nozzle;
- wherein the one or more nozzle orifices has a total orifice area of from about 5 mm2 to about 80 mm2;
- wherein the extended nozzle has a nozzle angle of about 75° to about 85°;
- and
- wherein the extended nozzle has a protrusion length of from about 40 mm to about 75 mm;
- b. dispensing the hair treatment composition from the reservoir into the extended nozzle and out the one or more nozzle orifices directly onto the hair as a foam by causing the hair treatment composition to travel parallel to an extended nozzle longitudinal axis from a point on the extended nozzle longitudinal axis that intersects with a vertical reservoir axis extending vertically from the outer contour defining the reservoir and until reaching the one or more nozzle orifices;
- and
- wherein the foam has a specific volume of from about 6 ml/g to about 10 ml/g;
- c. leaving the foam on the hair for from about 5 minutes to about 60 minutes;
- and
- d. rinsing the foam from the hair.
