Abstract

Method for assessing condition of skin and/or scalp by resulted color from the interaction of protein detecting composition with skin and/or scalp sample. Also disclosed is a method for comparing condition of different skin and/or scalp using the above method. Such conditions include, for example, skin healthiness and dandruff condition of scalp.

Claims

1. A method for assessing condition of skin and/or scalp comprising the steps of:

providing at least one sample of skin and/or scalp;

providing a protein detecting composition;

contacting the skin and/or scalp sample with the protein detecting composition for a time period sufficient for the protein detecting composition to interact with the sample and produce color, wherein the protein detecting composition is selected from the group consisting of biuret reagent composition, bicinchoninic acid composition and mixtures thereof; and

assessing color of the contacted skin and/or scalp sample;

wherein the color of the contacted skin and/or scalp sample is associated with representative skin and/or scalp conditions as described in table 1 and/or table 3.

2. The method, according to claim 1, wherein the skin and/or scalp condition is selected from the group consisting of skin and/or scalp cleanness, skin and/or scalp health, dandruff condition of the scalp, and combinations thereof.

3. The method, according to claim 1, wherein the skin and/or scalp sample is an in-vitro sample.

4. The method, according to claim 1, wherein the color is assessed by direct visual inspection.

5. The method, according to claim 1, further comprising the step of treating the skin and/or scalp sample using a cosmetic treatment.

6. The method, according to claim 5, wherein the cosmetic treatment is selected from the group consisting of a hair, scalp, facial or body cleansing composition;

a hair, scalp, facial or body conditioning composition;

a scalp care leave-on composition; and

combinations thereof.

7. The method, according to claim 1, further comprising the step of utilizing said assessment to support advertising claims about the efficacy of a cosmetic treatment.

8. A method for assessing and comparing condition of skin and/or scalp comprising the steps of:

providing at least two different samples of skin and/or scalp;

providing a protein detecting composition, wherein the protein detecting composition is selected from the group consisting of biuret reagent composition, bicinchoninic acid composition and mixtures thereof;

contacting the samples with the protein detecting compositions for a time period sufficient for the protein detecting composition to interact with the samples and produce color;

assessing colors of the contacted skin and/or scalp samples;

wherein the colors of the contacted skin and/or scalp samples are associated with representative skin and/or scalp conditions as described in table 1 and/or table 3; and

comparing the conditions of the skins and/or scalps.

9. The method, according to claim 8, wherein the samples differ from each other by the origin of the skin and/or scalp, the portion of the skin and/or scalp, and/or the treatment(s) applied to the skin and/or scalp.

10. The method, according to claim 9, wherein one sample comprises untreated skin and/or scalp and the other sample comprises skin and/or scalp treated with a cosmetic composition.

11. The method, according to claim 10, further comprising the step of utilizing said assessment and comparison to support advertising claims about the efficacy of a treatment versus non-treatment.

12. The method, according to claim 8, wherein the samples are treated with different cosmetic treatments.

13. The method, according to claim 12, further comprising the step of utilizing said assessment and comparison to support advertising claims about the superiority of one cosmetic treatment versus the other.
