Abstract
Abstract The subject matter of the invention is an agent and a method for improving the condition of hair on the basis of a combination of 0.1 to 25.0% by weight of trimethyl ammonia acetate betaine of the formula (CH3)3N(+)-CH2-COO(-) and 0.1 to 10.0% by weight of at least one aliphatic organic acid as a hair conditioning component. Preferred forms of preparations are a hair conditioning rinse, a hair conditioning emulsion, a hair treatment kit, or a hair strengthener.
