A hair composition comprising one or more surfactants and an oil-in-water (O/W) emulsion, the emulsion comprising: a silicone mixture comprising a trialkylsilyl-terminated dialkylpolysiloxane having a viscosity of 40,000 to less than 100,000 mPa.s at 25 oC and an amino-silicone having a viscosity of from 1,000 to 15,000 mPa.s at 25 oC and an amine value of from 2 to 10 mg KOH per gram amino-silicone； a mixture of emulsifiers comprising one or more non-ionic emulsifiers, where the mixture of emulsifiers has a HLB value of from 10 to 16； and water. The emulsion is present in the hair composition from 0.1 wt% to 15 wt%. The emulsion has a D50 particle size of less than 350 nm. Also claimed is a process for the treatment of hair comprising applying to the hair, preferably in a wet state, the composition described above and optionally rinsing. The composition may be used for washing or conditioning of hair.
