Hair treatment compositions

A composition comprising:

• at least 50 wt. % of a volatile solvent;
• wherein the volatile solvent comprises at least a silicone solvent;
• and
• wherein the composition comprises at least 5 wt. % of the silicone solvent;
• a non-emulsified silicone pressure sensitive adhesive (silicone PSA) comprising a silicone resin and a polydiorganosiloxane;
• wherein the composition comprises the non-emulsified silicone PSA in an amount of 0.1 to 5 wt. %;
• wherein the silicone resin is a trimethylsilyl end-blocked polysilicate resin consisting essentially of triorganosiloxy units of formula R3SiO1/2, and tetrafunctionality units of formula SiO4/2 in a ratio of about 0.6 to 0.9 triorganosiloxy units for each tetrafunctional siloxy unit present in the polymer;
• wherein each R is a monovalent organic radical independently selected from C1 to C8 hydrocarbon radicals;
• wherein said polydiorganosiloxane is a silanol end-blocked polydiorganosiloxane fluid;
• wherein the non-emulsified silicone PSA is dissolved in the volatile solvent;
• and
• less than 2 wt. % water;
• wherein the composition is a leave-in hair styling composition.
