1. A method of repairing and preventing hair damage comprising:
a. applying to the hair a shampoo composition comprising:
i. from about 2% to about 50% of one or more detersive surfactants, by weight of the shampoo composition;ii. from about 0.1 to about 0.25 by weight, of a cationic guar deposition polymer having a molecular weight of from about 500,000 g/mol to about 2.2 million g/mol;iii. from about 0.1 to about 1.75 by weight, of a silicone emulsion comprising an insoluble polysiloxane having a general formula of R1-[O—SiR2]n—OR1, wherein n is an integer, R is a substituted or unsubstituted C1 to C10 alkyl or aryl, and R1 is a hydrogen or a substituted or unsubstituted C1 to C10 alkyl or aryl, wherein the insoluble polysiloxane has a molecular weight within the range from about 50,000 to about 500,000 g/mol, and an average particle size within the range from about 30 nm to about 10 μm, wherein a total content of a cyclic polysiloxane having a general formula: is present in the silicone emulsion in an amount less than about 2.5 wt % based on the total weight of the insoluble polysiloxane and the cyclic polysiloxane, wherein R is as defined above, wherein m is 4 or 5, iv. from about 20% to about 95% of a first aqueous carrier, by weight of the shampoo composition; b. rinsing the shampoo composition from the hair; c. applying to the hair a conditioner composition comprising:
i. a conditioner gel matrix comprising:
a) from about 0.1% to about 20% of one or more high melting point fatty compounds, by weight of the gel matrix;b) from about 0.1% to about 10% of a cationic surfactant, by weight of the gel matrix; wherein the cationic surfactant system comprises a mono-long alkyl quaternized ammonium saltc) at least 20% of a second aqueous carrier, by weight of the gel matrix;d) silicone conditioning agents d. rinsing the conditioner composition from the hair. |
