Use of a composition comprising a non-fermented rice peptidic hydrolyzate for stimulating hair growth

1. A non-therapeutic method to slow down hair loss and stimulate hair growth, the method comprising:

Providing a composition comprising at least one non-fermented rice peptidic hydrolyzate coming from the hydrolysis of rice grain proteins from the Oryza sativa L rice species, as an active agent, wherein at least 70% of the peptidic nature compounds present in the hydrolyzate are peptides with a size of less than 6 kDa; and

applying the composition to a portion of the anatomy having hair follicles;

where the non-fermented rice peptidic hydrolyzate results in an increase in β-cantenin labelling of the hair follicles thereby indicating an increase in the differentiation and growth of the hair follicles.

2. A non-therapeutic method to protect follicular adult stem cells as well as their specific microenvironment, the method comprising:

providing a composition comprising at least one non-fermented rice peptidic hydrolyzate coming from the hydrolysis of rice grain proteins from the Oryza Sativa L rice species, as an active agent, wherein at least 70% of the peptidic nature compounds present in the hydrolyzate are peptides with a size of less than 6 kDa; and

applying the composition to the scalp zone;

wherein the composition protects follicular adult stem cells.

3. The method of claim 2 , wherein the solubilized peptidic hydrolyzate comprises at least between 2 and 3 g/l of peptidic nature compounds.

4. The method of claim 2 , wherein the solubilized hydrolyzate is used in a quantity representing from 0.01% to 1% of the total weight of the composition.

5. The method of claim 1 , wherein the applying step is performed daily.

6. The method of claim 2 , wherein the applying step is performed daily.

7. The method of claim 2 , wherein the peptidic hydrolyzate is solubilized in one or more physiologically acceptable solvents, such as water, glycerol, ethanol, propylene glycol, butylene glycol, dipropylene glycol, ethoxylated diethylene glycol or propoxylated diethylene glycol, cyclic polyols, or any mixture of these solvents.

8. The method of claim 2 , wherein the solubilized peptidic hydrolyzate comprises at least between 1.5 and 4 g/l of peptidic nature compounds.

9. The method of claim 2 , wherein the solubilized hydrolyzate is used in a quantity representing from 0.001% to 5% of the total weight of the composition.

10. The method of claim 2 , further comprising a soy peptidic hydrolyzate.

11. The method of claim 10 , wherein the non-fermented rice peptidic hydrolyzate and the soy peptidic hydrolyzate are present at concentrations of between 10 and 90%.

12. The method of claim 2 , wherein at least 85% of the peptidic nature compounds present in the hydrolyzate are peptides with a size of less than 6 kDa.

13. The method of claim 1 , wherein the peptidic hydrolyzate is solubilized in one or more physiologically acceptable solvents, such as water, glycerol, ethanol, propylene glycol, butylene glycol, dipropylene glycol, ethoxylated diethylene glycol or propoxylated diethylene glycol, cyclic polyols, or any mixture of these solvents.
