Abstract
Methods and compositions for preventing or reducing hair frizz. The compositions are preferably oil-in-water or water-in-oil emulsions comprise at least one polysiloxane fluid component selected from an amodimethicone and a polysiloxane component comprising a plurality of hindered amine side chains. The compositions also comprise a silicone-compatible, volatile or non-volatile liquid carrier component, preferably comprising a component selected from a low molecular weight, volatile siloxy component; a hydrocarbon; and an alcohol. The compositions are preferably combing cremes, sprays or mousses, and are suitable for use a “leave-in” hair care product, or as a touch-up hair care product suitable for use during the day.
Claims9
A method of reducing hair fizz, comprising the steps:
- I) applying to hair an emulsion lacking a detersive component comprising
- a) about 2.5% to 5% by weight of propoxytetramethyl piperidinyl dimethicone component,
- b) selected from the group consisting of dimethicone, dimethiconol, phenyl methicone, phenyl methiconol, a phenyl trimethicone, diphenyl dimethicone, phenyl dimethicone, diphenylsiloxy phenyl trimethicone, hexamethylsiloxane, disiloxane, trisiloxane, cyclotetrasiloxane, cyclopentasiloxane and cyclohexasiloxane volatile or non-volatile liquid carrier component;
- and
- c) water, and
- II) distributing said composition along a plurality of hair shafts;
- in which, when said emulsion is applied to frizzy hair and permitted to dry according to said method, said hair displays a reduction in hair frizz after incubation at 80° F. and 80% humidity for 6 hours relative to as compared to the amount of hair frizz observed in identical frizzy hair treated with an otherwise identical emulsion in which the propoxytetramethyl piperidinyl dimethicone component is substituted with dimethicone and incubated under identical conditions for an equal time period.
