Abstract

A method is provided which provides shine to hair comprising spraying a leave-on composition to hair with a particle size in the range of from about 0.01 μm to about 10 μm, wherein the resulting film at the dried hair is in the range of from about 100 nm to about 500 nm and more than 25% of the hair fibers are covered. The oil-in water polysiloxane emulsion shows a viscosity of less than 7 Pa*s and a pH value from about 4 to about 8. The emulsion comprises about 0.1% to about 10% by weight of a non-volatile polysiloxane fluid and from about 0.003% to about 0.6% by weight of a rheology modifier, wherein less than 0.015 g of the non-volatile polysiloxane fluid are applied per gram hair.
