The present invention relates to an anhydrous composition for treating keratin fibres, in particular human keratin fibres such as the hair, comprising (i) at least one fatty phase (A) comprising at least one oil and (ii) at least one anhydrous non-oil phase (B) comprising at least one polyol, wherein said phases (A) and (B) are visually distinctive from each other. The composition further comprises at least one non ionic surfactant (i) having an HLB higher than 9 and at least one non ionic surfactant (ii) having an HLB less than or equal to 9 in an amount higher than 0.2% by weight relative to the weight of the anhydrous composition. The weight ratio between the non ionic surfactant (i) and the non ionic surfactant (ii) is in the range of 5.5 to 12.5. The invention also concerns a process for treating keratin fibres, in particular human keratin fibres such as the hair, and a use for hair care employing the said composition.
