Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
Ah. Love love love this shampoo. I’m a brunette with bleached hair and this takes the yellow right out of it. Obviously your hairdresser needs to lighten your hair to a reasonable shade, this doesn’t lighten your hair, it removes the unwanted brassiness.
Excellent quality! This last me a year with half Ombre as blonde but had to go up to 1L because I had it redone to a full head of blonde. this product saves me money going to and from the hairdressers❤
