The invention is directed to a hydratable concentrated surfactant composition. The composition is pourable, easy to dilute, substantially free of sulfate and oil, comprises a C.sub.6-C.sub.14 acid, alcohol or both, an anionic surfactant comprising acyl isethionate and an amphoteric surfactant, zwitterionic surfactant or both. The composition is in lamellar phase and thickens and transforms to an isotropic phase upon dilution. The composition can be used as a concentrate in small volumes and diluted as used and needed or can be diluted with water in refill packaging to ensure a reduction in plastic waste.

The invention relates to a process for the cosmetic treatment of keratin fibres, in particular human keratin fibres such as the hair, implementing the application of a composition comprising at least one surfactant, and the application of a composition comprising a particular metal compound and a conditioning agent chosen from cationic surfactants and/or fatty alcohols.

A fragrance composition which reduces malodor during chemical treatment of keratin fibers is described. The keratin fibers may be human keratin fibers, such as human hair. The fragrance compound comprises p-mentha-8-thiol-3-one, cis-3-hexenol, cis-3-hexenyl acetate, and allyl amyl glycolate and further comprises one or more organic solvents selected from the group consisting of benzyl alcohol, dipropylene glycol, isopropyl myristate, and ethanol in an amount of 1% by weight or more, calculated to the total weight of the composition.
