Platinum rescue
This is my FAVORITE purple shampoo, I have been platinum for over a year now and I use this every other wash and it keeps my hair looking bright and fresh! I will say if you use it too often it starts to give your hair a purple hue but stick to using it every other wash and your set! It does not have a strong chemical smell and rinses out well! I will say you may need a good conditioner to keep your hair soft and hydrated.

    Whether you have grey hair, natural blonde hair, or fake blonde hair - you need this! I have naturally very dark hair and I have been getting blond balayage for over 6 years now. I LOVE this product for brightening my hair and removing any brass. You only need to let it sit for a minute or two, and you’re good to go. I do have very oily hair, so I don’t experience any dryness. Do be aware that if you leave it in for ~5 mins or longer, it may (temporarily) color your hair purple a bit. That just goes to show how potent and fast-acting it is! Love this stuff and will repurchase as long as I dye my hair blonde!!

    Purple color stains my hands for a couple of days after I wash my hair. When I left it in my hair for a couple of minutes, as directed by a stylist, it stained my hair a grey looking color. I would rather have a red tint to my hair than the purple staining my hands, hair and shower. When wiped off no stain occurs.

    I used the Opalex conditioner and the shampoo after bleaching my own brown hair. This definitely took away the orange, and gave me a more yellow. I’ll probably wash it with this a couple more times to get the whiter (cool) color I want. I left both the shampoo and the conditioner in for 5-10 minutes.
    It did tint my hands and nails purple but both times, after I set my timer, I used my [dollar tree] acne face wash and it took it right off.

    5.0 out of 5 stars Effective for Blonde Toning, but Don’t Forget to Moisturize!
    Reviewed in the United States on August 27, 2024
    Verified Purchase
    The Olaplex No. 4P Blonde Enhancer Purple Toning Shampoo is a fantastic product for maintaining and enhancing blonde hair. It does a great job of neutralizing brassy tones and keeping blonde hues looking fresh and vibrant. I’ve noticed a significant improvement in the brightness and overall color of my blonde hair since I started using it.

    However, while the shampoo excels at color correction, it tends to leave my hair feeling a bit dry and less moisturized. To counteract this, I recommend using a good conditioner or hair mask afterward to restore moisture and keep your hair feeling soft and healthy.

    I have naturally brown hair with very warm undertones. My hair has blonde highlights (even with ash blonde toner it usually goes warm after a few washes). Since using this weekly my hair has been a lovely ashy blonde and has doubled the time between colours. Have tried so many purple shampoo's and this has been the most expensive but best so far. Lasts for ages too.

    It’s just as if I went for toning at the salon. Keep it for 2-3 mins for a usual wash or for 5 minutes for a toning effect to kick orange tones out. Better use tangle teaser or another brush because I still had some parts where it didn’t reach
