    Description

    FIELD OF THE INVENTION



    [0001] The present invention relates to a method of treating hair more precisely. More particularly, the present invention relates to a method of treating hair more precisely comprising providing a hair treatment composition in a foam dispenser having an extended nozzle and dispensing the hair treatment composition directly onto the hair as a foam.

    BACKGROUND OF THE INVENTION



    [0002] Various methods are known for coloring and bleaching the hair. These methods include the application of liquid hair treatment compositions and foam hair treatment compositions. Known methods including each of these compositions have drawbacks.

    [0003] Known liquid hair treatment methods can be messy - liquid often runs down the skin of the scalp onto the face and the neck. To address the drawbacks of liquid hair treatment methods, foam hair treatment methods have been developed. Unlike liquids, foam does not run down the skin of the scalp onto the face and the neck.

    [0004] However, the current structure of foam dispensers makes dispensing foam directly onto the hair difficult to achieve without losing precision and control. Therefore, current foam hair treatment methods direct consumers to first dispense the foam into the hand rather than directly onto the hair. Dispensing foam into the hand results in a lack of precision and control in the application of the foam to the hair, especially to the roots. An oxidative hair colorant composition to be dispensed from a manually-actuable, non-aerosol dispenser as a foam, is known from WO 2011/075657 A2.

    [0005] Based on the foregoing, there is a need for a method of treating the hair more precisely which includes a foam dispenser designed for dispensing foam directly onto the hair.

    SUMMARY OF THE INVENTION



    [0006] According to an embodiment of the invention, there is provided a method of treating hair more precisely, the method comprising (a) providing a hair treatment composition in a foam dispenser, wherein the foam dispenser comprises (i) a reservoir for holding the hair treatment composition; (2) an extended nozzle fluidly connected to the reservoir; wherein the extended nozzle comprises one or more nozzle orifices; wherein the one or more nozzle orifices has a total orifice area of from about 5 mm2 to about 80 mm2; and wherein the extended nozzle has a protrusion length of from about 20 mm to about 125 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; wherein the foam has a specific volume of from about 4 ml/g to about 20 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.

    [0007] According to yet another embodiment of the invention, there is provided a hair treatment kit comprising (a) a hair treatment composition selected from the group consisting of hair colorant compositions, hair bleaching compositions, highlighting compositions, conditioning compositions, and combinations thereof; (b) a foam dispenser comprising (i) a reservoir for holding the hair treatment composition; (ii) an extended nozzle fluidly connected to the reservoir; wherein the extended nozzle comprises one or more nozzle orifices; wherein the one or more nozzle orifices have a total orifice area of from about 5 mm2 to about 80 mm2; and wherein the extended nozzle has a protrusion length from about 20 mm to about 125 mm; and (c) a set of instructions comprising directing a user to dispense the hair treatment composition directly from the foam dispenser onto the hair as a foam.

    [0008] These and other features, aspects, and advantages of the present invention will become evident to those skilled in the art from a reading of the present disclosure.

    EXPERIMENTAL DATA



    [0041] Referring to Table 1, 17 hair color consumers were asked to simulate using the following extended nozzle foam dispensers with different protrusion lengths. The consumers were then asked to rank the protrusion lengths based on precision and control for dispensing foam directly onto the hair. A ranking of 1 correlates to the most preferred protrusion length, and a ranking of 5 correlates to the least preferred protrusion length. The percentages in Table 1 show how the consumers ranked each protrusion length, rounded to the nearest tenth. The last column of Table 1 shows the percentage of consumers who ranked each protrusion length as most preferred or as second most preferred for precision and control.
    Table 1
    Protrusion Length123451+2

    110 mm 23.5% 11.8% 11.8% 29.4% 23.5% 35.3%


    [0042] Referring to Table 1 and Fig. 7, 29.4%, 58.8%, 64.7%, and 35.3% of consumers ranked the 35 mm, 50 mm, 65 mm, and 110 mm lengths as most preferred or second most preferred for precision and control. These numbers were notably higher than the 11.8% of consumers who ranked the 5 mm length as most preferred or second most preferred.

    [0043] Now referring to Table 2, 17 hair color consumers were asked to simulate using the following extended nozzle foam dispensers with different nozzle angles. The consumers were then asked to rank the nozzle angles based on precision and control for dispensing foam directly onto the hair. A ranking of 1 correlates to the most preferred nozzle angle, and a ranking of 5 correlates to the least preferred nozzle angle. The percentages in Table 2 show how the consumers ranked each nozzle angle, rounded to the nearest tenth. The last column of Table 2 shows the percentage of consumers who ranked each nozzle angle as most preferred or as second most preferred for precision and control.

    120° 5.9% 0% 5.9% 29.4% 58.8% 5.9%


    [0044] Referring to Table 2 and Fig. 8, 76.4% and 82.3% of consumers ranked the 80 ° and 90 ° angles as most preferred or second most preferred for precision and control. These numbers were notably higher than the 11.8%, 23.6%, and 5.9% of consumers who ranked the 70 °, 100 °, and 120 ° angles as most preferred or second most preferred.

    [0045] Of the 17 consumers who participated in the above studies, 9 of the consumers stated that they had previously used foam dispensers to color their hair. The 9 consumers who previously used foam dispensers to color their hair were then asked to color their hair using an extended nozzle foam dispenser as described above. When given the opportunity to choose between their old foam dispenser and an embodiment of the present invention, 8 of the 9 consumers (89%) chose an embodiment of the present invention.

    [0046] In a different study, 10 consumers who previously used liquid dispensers to color their hair were asked to color their hair using an extended nozzle foam dispenser as described above. When given the opportunity to choose between their old liquid dispenser and an embodiment of the present invention, 9 of the 10 consumers (90%) chose an embodiment of the present invention.
