Very good
A little pricey but worth it, I have a bronde balayage and this keeps my hair healthy!

Shiny hair
The results are a lot milder than I expected (I expected to see a more ashy tone to my hair after a few washes), it’s definitely cooled it down just not as significantly as I had hoped. My favourite thing is the shine on my hair after using this shampoo & my least favourite thing is I find it to be quite drying & have even noticed more hair fall after using it (using it once/twice per week between regular washes). Once I achieve the desired tone I will decrease usage & continue with it as a maintenance product from time to time.

Drying
A huge fan of Olaplex, however I have found the product to be very drying on the scalp, causes itchy dry skin. Now combining with a good scalp routine treatment, hopefully I will be able to use it again. Not much noticebly different tone after use

Good but I prefer the classics
Good enough but I much prefer the no.4 classic. Then I use purple shampoo separately. I like the idea of having both combined however my expectations from Olaplex are now so high after trying some of their other products. I feel like this one was a bit less effective than others in terms of improving hair condition, feel snd look.
