  • Works well in white hair
It freshens the color of my white hair. The first bottle I purchased at the salon. This one was a little cheaper.

  • Great shampoo
This product line is fabulous for your hair. It makes your hair stronger. It gives it a shine. It's great for older women like me. I love it! I have no problem paying extra for it. I do recommend this product and everything else in the line

  • Great smell and results
I’ve tried many of these purple shampoos through the years. My light brown hair has stubborn grays that require warm color to cover them up. Unfortunately the color fades more golden than I prefer. I left this shampoo on for 3 minutes and love the toning! I’ve only used it once but plan to use it weekly. ... show more

  • Amazing shampoo but more like a toner
I love this shampoo. I bought it because my blonde hair would get so brassy between hair appointments. My hair stylest always uses a toner which makes it look a lot better. She keeps telling me to get purple shampoo. I researched and decided to buy Olaplex due to the good reviews and it absolutely was worth the price tag! The toner in it is the exact same affect as the toner my hairdresser uses. I go back next week and usually by now my hair is almost yellow. This time it is as pretty as it was my last visit, minus the dark roots and dead ends. :). However, this is not a moisturizing shampoo. I have thick, curly hair so have to buy another shampoo that is geared towards my hair type. So I alternate this shampoo with that one. This means I use Olaplex about once per week. I spend a lot of money on my hair because of the texture, length and thickness. Olaplex lives up to my high expectations! ... show more

  • Helps with the brassy look
This is a must use for people with processed blonde hair that tends to turn brassy quickly. I combined this the Oloplex 4 shampoo to make it nice and sudsy then I leave it on at least three minutes. And it helps with the brass definitely worth buying this product even if it is expensive.

  • Best purple shampoo I’ve ever used
I like this Ola Plex, purple shampoo because it doesn’t make my hair feel dry after use. I have used many purple shampoos for my blonde hair over the years and have never found one that doesn’t dry out my hair until I found this product. The smell is subtle and smells nice and fresh. The color of the product is a deeper purple to bring out the best blonde hues and remove yellow toned blonde. This purple shampoo is my favorite and a must buy! ... show more

  • I LOVE the way it makes my hair feel
I’ve tried several different types of shampoos on my hair and this is the absolute BEST!! I have salt and pepper colored hair and this is the only one that has worked!! I just ordered a second bottle even though I just bought one! Love this product! Conditioner is great too!
