(ii) from about 0.1% to about 10% of a cationic surfactant system, by weight of the conditioner gel matrix; and
(iii) at least 20?/o of a second aqueous carrier, by weight of the conditioner gel matrix;
(h) rinsing said second conditioner composition from the hair with water;
wherein steps (e), (f), (g), (h) are repeated one or more times until the desirable hair copper content is achieved; and
(i) a leave-on treatment comprising 0.05-0.5% of a rheology modifier and about 0.025% to about 1%, by weight of a chelating compound selected from the group consisting of ethylenediamine-N,N′-disuccinic acid (EDDS), derivatives of ethylenediamine-N,N′-disuccinic acid, salts of ethylenediamine-N,N′-disuccinic acid, salts of derivatives of ethylenediamine-N,N′-disuccinic acid, histidine and mixtures thereof, the leave-on treatment applied after any of steps (d) (f) or (h).
2.

3. The method of claim 1 , wherein the method mitigates the absorption of copper in hair to an increase of less than 10%, measured by the increased copper content after the completion of steps (a) to (h) and repetition of steps (e), (f), (g), (h) twenty times, using water containing 0.06 ppm of copper from the copper content before the application of the method.
