Often touted as the holy grail for hair, this purple version of the famous Olaplex is no different. It’s highly concentrated and promises to tone our blonde hair while cleansing and repairing. We did what the bottle recommended and pre-washed our hair with another shampoo to remove any build up, then lathered up with this and let it do its work for the recommended one to three minutes (we opted for a minute and a half). Our hair was left feeling salon-fresh, perfectly toned and with a lovely scent to boot.
They say blondes have more fun, but that statement can be called into question when it comes to the maintenance of an icy, cool sheet of glossy blonde.
After walking out of a salon appointment with platinum locks, you’ll want to maintain the look. Over time, though, your hair can end up looking ‘brassy’, with orange and undesirable warm tones caused by heat damage from hair styling tools, pollution, UV damage or washing with a shampoo that does not protect coloured hair.
A good purple shampoo is a form of hair toner that will banish this brassiness, distributing purple pigment throughout the hair to neutralise brassy tones.
“The purple pigment inside the product is designed to neutralise any yellow or brassy tones that can occur, especially if you live in a hard-water area, such as London.
“I always recommend to start using a purple shampoo or conditioner two weeks after hair has been freshly coloured, and carry on using fortnightly to weekly when you are due a colour top up or have been on holiday in the sun.”
We tried 10 of the best on the market to help you keep your tresses icy cool.
How we tested
We tested each shampoo on cool-toned blonde highlighted hair, putting them to the test of whether they could keep our hair icy, as well as whether they could add some extra strength, shine and, of course, scent to our hair.
