shampure range I began with first as my hair was in no state to get coloured & my hairdresser wouldnt do it either, now I thank her for that. Reusing this range I believe saved my hair which was always extremely shiny, healthy & something I was very proud of & was complimented about many times ...... when I was sick, people would,over & over would mention the state of my hair. Anyway, it became healthy enough to tolerate a colour treatment eventually (& I thank Aveda for that) this shampoo in incredible. I love that my hair has returned to its shiny state again,is regrowing & the colour looks so good & lasts so well & thats in no small way the result off this brand & this shampoo......that is what I believe. These products & this one is so incredible on hair, it smells divine, clean, beautifully perfumed & it lathers up luxuriously. I cant recommend it highly enough & I was also impressed with Adore Beauty who sent my order immediately,.....I received in around 2 days & will be re purchasing this shampoo thru this company again. !!
