Favourite purple shampoo

5 stars out of a maximum of 5

When I put this on you can notice the difference afterwards, my hair looks so much more brighter and blonder, whilst also keeping your hair healthy and feel hydrated. This shampoo definitely doesn’t dry out your blonde like other purple shampoos do!

Favourite purple shampoo

5 stars out of a maximum of 5

Love this, gives a good clean blonde without turning the hair purple or grey, doesn’t dry it out as much as some other brands also.

My go to purple shampoo, which I mix with a tiny blob of olaplex shampoo to help lather, works a treat!

Good

4 stars out of a maximum of 5

It’s a good purple shampoo. Nothing special though. It didn’t make any major differences to hair colour

Does the job

5 stars out of a maximum of 5

Makes my hair less brassy and toned does exactly what it says it does. Doesn’t leave my hair really dry after either albeit it’s still dry so I do lather on lots of conditioner when I use this. Happy with it though probably the best silver shampoo I’ve tried.

Good toning shampoo

4 stars out of a maximum of 5

I have long highlighted blonde hair and this shampoo eliminates any brassy tones. I leave it on for a couple on minutes. It doesn’t stain my hands and my hair feels clean after. I knocked a star off because it is pricey and I’m not sure I’d notice it was olaplex.

Great for your blonde

5 stars out of a maximum of 5

Best blonde shampoo I’ve used and olaplex has saved my damaged hair. This means I can wash my hair with olaplex plus brighten it once a week without losing the olaplex benefits.

Soo knotty

2 stars out of a maximum of 5

Yes this will tone your hair but you will spend the next hour trying to brush your hair because it’s so knotty afterwards. If you use this, use a really thick conditioner or hair mask and you’ll be okay. I wouldn’t say this is a must have, there are better out there but no harm in getting it if you’re set on it!

Lovely luxury treat, left my hair soft and the gave the blond a boost.

5 stars out of a maximum of 5

As other reviewers have said, this is quite expensive but it is such a nice treat for your hair. Its a good purple shampoo that doesn't leave my dyed hair feeling dry (which I find lots of purple shampoos do). My hair can we quite frizzy and the No3 Perfector definitely took down the frizz. The conditioner is one of the nicest I've used and leaves my hair soft. Boosts blond hair and leaves it feeling soft and strong.
