1. A stable concentrated hair care composition comprising:
- a) from about 20 weight % to about 45 weight % total surfactant;
b) from about 6 weight % to about 30 weight % branched anionic surfactant with a tail having an alkyl chain with 12 to 18 carbon atoms;
c) from about 4 weight % to about 15 weight % linear anionic surfactant with a tail having an alkyl chain with 12 to 18 carbon atom;
d) from about 2 weight % to about 12 weight % water-miscible solvent;
e) from about 0.05% to about 1% of a cationic polymer; and
f) from about 35 weight % to about 78 weight % of water;
wherein the concentrated hair care composition is a shampoo, has a Ratio of (Linear anionic surfactant/Branched anionic surfactant)/Miscible solvent of less than about 0.2, a ratio of branched anionic surfactant/miscible solvent of less than about 5, and a viscosity of less than 500 cP at 26.5°

Abstract
The invention relates stable, low viscosity hair care compositions having high surfactant content comprising linear sulfates (with alkyl tail of C12 and above) and branched sulfates (with alkyl tail of C12 and above), a water-miscible solvent such as dipropylene glycol or glycerin. Suitable compositions have a ratio of (Linear anionic surfactant/Branched anionic surfactant)/Miscible solvent from about 0.2 to about 5 and a viscosity of less than about 500 cP at 26.5° C.
