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.

First claim

What is claimed is:

1. 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 mm 2 to about 80 mm 2 ;
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.

2. The method of claim 1 , wherein the hair treatment composition has a viscosity of from about 1 cps to about 1,500 cps.

3. The method of claim 1 , wherein the foam dispenser is selected from the group consisting of squeeze foam dispensers, aerosol foam dispensers, pump foam dispensers, and combinations thereof.

4. The method of claim 1 , wherein the reservoir is composed of a material selected from the group consisting of rigid materials, flexible materials, and combinations thereof.

5. The method of claim 1 , wherein the hair treatment composition is either a hair color composition or a hair bleaching composition.

6. The method of claim 1 , wherein the total orifice area is from about 12 mm 2 to about 50 mm 2 .

7. The method of claim 1 , wherein the foam is dispensed directly onto the hair as a noodle of foam.

8. The method of claim 7 , wherein the noodle of foam has an average diameter of from about 5 mm to about 40 mm.

9. The method of claim 1 , wherein the extended nozzle further comprises a closed nozzle tip.

10. The method of claim 1 , wherein the extended nozzle is selected from the group consisting of detachable nozzles, telescoping nozzles, flexible nozzles, hinged nozzles, and combinations thereof.

11. The method of claim 1 , further comprising using the extended nozzle to part the hair.
