Best purple shampoo I’ve tried 🙌
Best purple shampoo I’ve ever used, it works so well, I leave it on for 15-20 mins and only have to do this once every 10 days, it really takes the warmth right out of where my hair transitions from light brown to blonde.

Did the job; just didn’t wow me
I have had this a couple of months and have used it all up. I used it as and when I thought my blonde hair looked brassy. It would definitely get rid of the brassy tones, just not for long (which I’m guessing they don’t) it helped to hydrate my hair and gave it a smooth texture. It’s certainly not the love of l life; I will keep trying other shampoos like this until I found the one. This one was great, just not overly wowed

Best purple shampoo hands down
I have been using this product for years. It is so good for the nuetralization of brassy tones, but also leaves my hair in such good condition and really is worth it compared to other purple shampoos put there

Love this Shampoo
I have tried every Shampoo on the market and I love this the best, I have fine, highlighted hair and hate seeing my hair yellow or strawberry blonde, this shampoo tones down those shade. It makes you hair feel very soft too.
