This Purple shampoo from Olaplex in my opinion is by FAR the best if you want to get rid of brassiness or just give your hair a freshly new toner look. I use this once a week when I get to my last 4 weeks before I need to go for my hi-lites and it is absolutely incredible. I have received so many compliments after a wash. I wash my hair the 1st shampoo with my personal choice and then try and ring out as much water as I can, lather the purple shampoo on and then do a shave to make up a little time (as I do believe the trick is to leave it on for a good 5min to get the perfect results) then rinse out and condition as usual and then style. It does not leave that "purple" look on some of your righter parts but instead makes everything a beautiful ashy blonde. The best for me is that my hair don't feel like grass as some purple shampoo's make you feel and does not make my already oily hair oily at all. It is on the more expensive side but this is more of a extender to keep your blonde hair fresh than a daily use so will last for months on end. Just absolutely love the look of my blonde colour after. Best Purple shampoo!

I love this product, I use it once a month. It tones down unwanted brassy/yellow tones incredibly but doesn’t overtone. It gives you that fresh salon feeling and leaves your hair feeling super healthy. You do have to be careful regarding the amount you use and how often as overuse can damage your hair.

Leaves my hair so much softer then any normal purple shampoo. Only left it in for a couple minutes and it toned down the yellow so nicely. Doesn’t leave it feeling overtoned or purple or patchy and gives it a much nicer tone then any purple shampoo I’ve used before

I am super impressed with this product. It makes your hair feel so soft and it does an amazing lift in your colour without the grassy feel like some purple shampoos and without a purple streak here and there like others sometimes do. Only tiny negative is that it does not foam as well on the 1st wash but I use the normal Olaplex for the 1st wash and the the purple Olaplex for the 2nd and leave it on for a while. I would say for colour and health is this the best purple shampoo I have ever used. Your hair will love you for it!
