A hair care product contains (A) 0.1 to 30 % by weight of at least one organic and/or inorganic thickener; (B) 0.1 to 25 % by weight of at least one fixing water-soluble polymer which may be totally or partially precipitated by a change in pH; and (C) 45 to 99.8 % by weight water. This hair care product is (D) free from organic solvents and (E) has a pH value at which the component (B) is totally or partially precipitated. This product does not stress the hair and is thus particularly suitable for fine hair. In particular as a hair fixing product, it keeps the hair in place without glueing the hair or stressing it with an excess of fixing polymers. Fine hair becomes lush and full.
