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

I dyed my hair nor long ago and was worried about damage, nut after using this shampoo, it feels long-lasting and I’m really satisified.

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.

OMG!!
Okay guys, I really wish I could show B&A’s so feel free to message me on Instagram, I’m no gatekeeper and would love for someone to feel as ecstatic as I did when I tried this shampoo!!
This time last year I had black box-dyed hair (had been doing for over 2 years) if anyone knows their stuff, they’d know that no matter how much you bleach your hair, there will always be red undertones that you literally have to grow out. Anyway, after a trust the process kinda year, my hairdresser finally gave me the thumbs up to go light blonde balayage.. with in 2 weeks my undertones made a return and my hair was yellow and brassy :( I decided to use this shampoo and honestly the results after just ONE use are incredible!!!
My hair is now a lovely light ash blonde and my balayage is really popping through nicely.
As i have only used this once I am unsure how long it will last and what will happen the next time I use this but at this point in time I would give this product 6 stars if I could!!
It is so noticeable, I think it’s better than a toner if that’s even possible!
Honestly don’t mind if anyone wants to message me for B&A’s 🥰x
