Claim:
A process for at least one of pre-treating and post-treating keratin fibres in a bleaching process using at least one bleaching composition, comprising applying to the keratin fibres a pretreatment or post-treatment composition comprising at least one aminosilicone chosen from formulae (I) and (II): wherein: m and n are numbers with a sum (n+m) ranging from 1 to 1000, n is a number ranging from 0 to 999, and m is a number ranging from 1 to 1000; and R 1 , R 2 and R 3 , which may be identical or different, are chosen from a hydroxyl radical and C1–C4 alkoxy radicals, wherein at least one of the radicals R 1 to R 3 is chosen from alkoxy radicals; wherein: p and q are numbers with a sum (p+q) ranging from 1 to 1000, p is a number ranging from 0 to 999, and q is a number ranging from 1 to 1000; and R 1 and R 2 , which are different, are chosen from a hydroxyl radical and C 1–C 4 alkoxy radicals, wherein at least one of the radicals R 1 and R 2 is chosen from alkoxy radicals.
