Writer Emily Sleight usually uses Amika silver shampoo to keep the brassiness out of her bleach blonde hair, and admits it would take a lot for her to make the switch to another product.
However, for the purposes of a review, she's recently tested out Olaplex's recently launched silver shampoo, which retails at a pricey £26.
Writing in the Liverpool Echo , Emily remarked that she found the "rich dark purple colour" to be "a little unnerving at first", but reasoned that plenty of silver shampoos have a similar shade.
