The present invention relates to a substantially dry, disposable personal care article comprising: a) a water insoluble substrate comprising a nonwoven layer; and b) a therapeutic benefit component, disposed adjacent to said water insoluble substrate, wherein said component comprises from about 10% to about 1000%, by weight of the water insoluble substrate, of a therapeutic benefit composition comprising: c) a safe and effective amount of a cationic polymer exhibiting a Relative Hydrophobic Contribution of from about 0.2 to about 1.0; d) a safe and effective amount of an anionic surfactant; wherein said composition forms a coacervate when said article is exposed to water. These articles have been found to be particularly useful for personal cleansing applications, namely for the skin and hair. Thus, the present invention further relates to methods of cleansing and/or therapeutically treating (e.g., conditioning) skin and hair utilizing the articles of the present invention.
