The top of my hair was light from highlights and the rest was brassy from previous highlights this completely fixed it  I couldn’t recommend this product more for yellow hair. I left it for 5 minutes and it did nothing so I tried 30 and it was perfect

this is a great very intense purple shampoo for blondes at a great price!!

I've had a number of silver / purple shampoos over the years. Sachajuan to this day is the best. This is fine but a dye heavy / inky shampoo no better than Charles Worthington from Boots

This, along with the silver conditioner, has saved my dyed blonde hair! It has turned my hair from slightly brassy to extremely cool toned and ashy which is just what I wanted. I have used other purple shampoos in the past and found them very drying, this one is not at all! Will definitely be repurchasing.

This has knocked out every brassy tone I get from living in a hard water area. Am transitioning from highlights to grey and this shampoo is really helping. It gives a Scandinavian gleam and helps my multi-tones look much fresher.

I received the shampoo last week today. I waited after I used it 3-4 times to write this comment just because normally the first time always works great when you switch to new products. But this is different. The result has been consistently awesome. It makes my bleached hair so soft and silky, and it adds a beautiful tone of ash! Even if you don’t leave it on for long but rinse straight away! Also the scent is sooooo nice! Great value and I will def purchase again.

The shampoo is very good, smells like the ones in the professional salons and is highly pigmented. However, used regularly, gives the hair a purple shade combined with ashy tones. Therefore, after a few uses, I wash my hair with a less pigmented shampoo to keep that shade of purple under control. The colour makes your hands blue but you can use gloves. I personally do not use them because the stain disappears after you wash your hands several times.

It is very good for blonde hair and if you want your hair to have a silvery look just leave it on a little bit more.

This product really does work well for brightening your blonde and makes a massive difference to the tone of my hair. I have balayage blonde/brown hair and it made it look much brighter and less yellow. I would say though that it has made my hair very dry. I would recommend you use a good moisturising conditioner after use or a hair treatment mask with it to avoid.

My hair looks and feels great after using.
