Abstract:
1. A reusable self-heating hair roller comprising: a fluid holding body having a shape compatible with curling or otherwise styling hair; said body being elongated and having first and second closed end portions of substantially matching size, a wall portion extending between said end portions providing a hair wrapping region of said body, and a main cavity defined by said wall portion providing a fluid chamber that is closed at each end by said first and second end portions; a supercoolable fluid sealed within said fluid chamber in fluid contact with said wall portion of said body, said supercoolable fluid being capable of being supercooled to room temperature while remaining in a liquid state, said supercoolable fluid being further capable of undergoing exothermic crystallization in response to a nucleation event in order to generate heat for hair curling, with said hair curling heat only having to transfer through said wall portion of said body and directly into hair wrapped around said hair wrapping region without passing through any other material; and a nucleation initiator in said body in contact with said supercoolable fluid.
