OLAPLEX No. 4P Blonde Enhancer Toning Shampoo, 250 ml (Pack of 1)

I have been lightening my hair over the last 4 years and recently (maybe due to the sun?) it looks yellow after about 4 washes. Maybe it’s the toner not being permanent I don’t know, not a stylist.I’ve used Olaplex for years and love it so thought I’d finally give this shampoo a try.Not only is it HIGHLY pigmented but it’s a thin/watery formula. A little goes a long way!I washed my hair as usual then did a wash with this product and it completely stained my hands that it took 4 washes with a scrub to remove it. It was on my hair for no more that 90 seconds as it was my first use I wanted to see what the effects were before leaving on for the recommended time.After rinsing, conditioner and then leave in conditioner I was shocked at how beautifully soft and manageable my hair was. It removed all the brassiness and left my hair feeling amazing. I will continue my regimen of only using this shampoo twice per month as I only put treatment’s in twice per month as I feel my hair isn’t dry or damaged (even with the lightening by my stylist) it even left me feeling like it doesn’t need hydration/moisture/repair treatments. I use function of beauty shampoo and conditioner once per week and alternate with Olaplex.Whenever I do use this in the future I’ll definitely use no3 and no5 to maintain my length, colour and strength of my hair. Not only does it smell amazing but it’s a different scent to the rest of the Olaplex line and I love that.Cannot recommend enough as it’s amazing. Buyer beware though use gloves so you don’t stain your hands and remove from skin around your hairline as soon as you can.

Okay product, not certain it's authentic olaplex as it did something strange to my hair. But nonetheless it did lessen the orange in my hair so that's something.

LOVE LOVE LOVE!! This is the BEST purple shampoo I have ever used. I’ve been blonde since I was 16 and using different purple shampoo, some high street brands and some luxury but have found this has to be the best. I usually do a shampoo or 2 shampoos of my normal to clean my hair and then use this once keeping it on between 3-5 minutes depending on how ashy I want my hair. The only thing I have found is if you have thin hair or thinner part of your hair that are more bleached than other strands it can go purple as it catches to the hair more. I tend to find I only get this on the very front of my fringe as the hair is very blonde with little natural hair colour through it and thin so I usually wash off my fringe first before the rest of my hair. I have used this twice in one wash before as well if you want really ash hair, just don’t leave on too long and it won’t go purple.

excellent product - you get what you pay for!

As someone who's constantly battling brass and maintaining my blonde highlights, I've tried countless purple shampoos - but Olaplex No. 4P has truly impressed me.Pros:Exceptional toning performance that neutralizes unwanted yellow and orange tones effectively. The purple pigment is perfectly balanced - strong enough to combat brassiness, but not so intense that it leaves a purple cast on the hair.True to Olaplex's reputation, this shampoo goes beyond just toning. It genuinely repairs and strengthens hair, which is crucial for chemically treated blonde hair that's prone to damage.The hydration factor is remarkable. Unlike many toning shampoos that can leave hair feeling dry and stripped, this formula maintains hair's moisture and softness.A little goes a long way - the 250ml bottle has impressive longevity, making it a cost-effective option despite the premium price point.Cons:The price is definitely on the higher end of hair care products. At around $30 for 250ml, it's an investment.Those with very light or very dark blonde hair might need to experiment with application time to get the perfect tone.The purple pigment can be slightly messy if you're not careful during application.What truly sets this apart is how it cares for hair health while toning. It's not just about appearance, but actually repairing and protecting blonde, lightened, and grey hair. The bond-building technology Olaplex is known for is evident in every wash.I recommend leaving it on for 3-5 minutes in the shower for optimal toning, and using it once or twice a week depending on your hair's needs. For anyone struggling with brassy tones or maintaining their blonde, this is a game-changer.A bit of a splurge, but absolutely worth every penny for those serious about hair care.
