Cosmetic method using a composition containing siloxane resins and powder dye

A cosmetic method for at least one of making up at least one keratin material and caring for at least one keratin material, comprising applying to the keratin material a composition comprising, in a physiologically acceptable medium:

• a) a siloxane resin comprising at least 80 mol % of units:
• (i) at least one M unit of formula (R′3SiO1/2)a and
• (ii) at least one Q unit of formula (SiO4/2)b
• wherein R′ independently represents an alkyl group comprising from 1 to 8 carbon atoms, an aryl group, a carbinol group, or an amino group, with the condition that at least 95 mol % of the R′ groups are alkyl groups,
• wherein a and b are values greater than 0, and
• wherein a ratio a/b is between 0.5 and 1.5;
• b) a propyl silsesquioxane resin comprising at least 80 mol % of at least one T unit of formula R″SiO3/2, wherein R″ independently represents an alkyl group comprising from 1 to 8 carbon atoms, an aryl group, a carbinol group or an amino group, with the condition that at least 80 mol % of the R″ groups are propyl groups;
• wherein a weight ratio between the resins a) and b) is between 1/99 and 99/1,
• wherein the resins a) and b) are not bonded to one another via covalent bonds, and
• wherein a number of M units in a final mixture of the composition is less than a number of T+Q units;
• and
• c) at least one pulverulent dyestuff that has been surface-treated with at least one hydrophobic agent selected from the group consisting of a fluorinated compound, a fatty acid, and an amino acid.
