A latex composition for hair care containing a spray-dried hybrid-graft copolymer of a sulfopolyester and an acid-functional polymer segment. The acid-functional polymer segment is formed from at least one acid-functional monomer, at least one ethylenically unsaturated monomer, and at least one amide-containing monomer. Such compositions exhibit superior curl retention even at high humidity.
