Hair care system, hair care method and use of a hair care system

A hair care system comprising:

• (A) a shampoo composition, comprising:
• (a) from 5 to 15 wt. % of at least one ethoxylated sulfate anionic surfactant having at least one degree of ethoxylation and/or its salt thereof;
• (b) from 1 to 10 wt. % of at least one non-ethoxylated sulfate anionic surfactant and/or its salt thereof;
• (c) from 1 to 5 wt. % of at least one amphoteric surfactant;
• (d) from 0.1 to 3 wt. % of at least one water-soluble quaternary ammonium compound;
• (e) an oil-in-water emulsion having a particle size D50 of less than 350 nm, and comprising:
• a silicone mixture comprising:
• (i) a polydialkylsiloxane comprising trialkylsilyl end groups, having a viscosity at 25° C. ranging from 40,000 to 70,000 mPa·s;
• and
• (ii) an aminosilicone having a viscosity at 25° C. ranging from 1,000 to 15,000 mPa·s and an amine number ranging from 2 to 10 mg of KOH per gram of aminosilicone;
• and wherein the weight ratio of the polydialkylsiloxane to the aminosilicone ranges from about 5:1 to about 1:1;
• a surfactant mixture comprising one or more non-ionic surfactants, said mixture having an HLB ranging from 10 to 16, and
• water;
• wherein the oil-in-water emulsion is present in the shampoo composition (A) in a total amount ranging from about 0.1% to about 10% by weight;
• all weights being based on the total weight of the shampoo composition, and
• (B) a conditioner composition, comprising:
• (a) from 0.5 to 2 wt. % of each of at least two different cationic surfactants, in a total amount of from 1 to 4 wt. % of cationic surfactant;
• (b) from 3 to 5 wt. % of at least one fatty alcohol;
• (c) from 2.2 to 3.1 wt. % of at least two silicones, wherein the first silicone is a polydialkylsiloxane, which is present at a range of 2.0 to 2.5 wt. % based on the total weight of the conditioner composition, and wherein the second silicone is an aminosilicone, which is present at a range of 0.2 to 0.6 wt. % based on the total weight of the conditioner composition;
• (d) water;
• all weights being based on the total weight of the conditioner composition.
