Introduced by my sis...Its really good for coloured hair. Red is well-known colour that will fade very fast.. usually it will fade to brown within a week or the most two... but this shampoo and condition can really really hold your hair colour so sO well... After one month... the hair colour still remain reD!!! Very very good!!! Althou its abit ex... but at least it help you save $$ to re-colour your hair again! And one tube can last for about 2 mths... depending on your hair lenght..but theres one thing.. this shampoo is mainly targeted for coloured hair.. so I feel that it is not moisturised enough.. so still got to treatment your hair frequently =)
