Pretreatment agent comprises 0.001-1.75 wt.% of at least one amino functional silicon compound (I) and at least 80 wt.% of water. Pretreatment agent comprises 0.001-1.75 wt.% of at least one amino functional silicon compound of formula (R1-Si(CH 3) 2-[O-Si(CH 3) 2] n 1-[O-Si(R)((CH 2) 3-NH(CH 2) 2NH 2)] m-[O-Si(CH 3) 2] n 2-O-Si(CH 3) 2-R2) (I) and at least 80 wt.% of water. R, R1, R2 : -OH, -O-CH 3, -O-CH 2-CH 3, -CH 3, -CH 2-CH 3, -CH 2-CH 2-CH 3, -CH(CH 3) 2, -C (CH 3) 3; m : 1-2000, preferably 1-10, where the sum of m, n1 and n2 is 1-2000, preferably 50-150; and n1+n2 : 0-1999, preferably 49-149. Independent claims are included for: (1) oxidative hair treatment comprising applying (I) on the keratin fibers and oxidatively treating the hair for 1 second to 24 hours; and (2) brightening keratin fibers, preferably human hair, comprising applying the pretreatment agent on the fiber, applying an agent M2 on the fiber, where if desired, the agent M2 is added before the application of another agent M3, rinsing the agent M2 after 5-60 minutes from the fiber and after the treatment applying an after-treatment agent M4 on the fiber and rinsing the after-treatment agent M4 after an exposure time of a few minutes, where at least one of the agent M2, M3 or M4 comprises at least one oxidant containing at least one peroxo compound, preferably hydrogen peroxide. |
