N°.4P Blonde Enhancer Purple Shampoo | Toning Hair, 250 mL | For Blonde, Lightened & Grey Hair; Violet Toning Agents; Suitable for All Hair Textures

Bought it to try as it was recommended in one of the articles I've read. Very sceptical as tried other products from different brands and they weren't doing the job. This one actually works! Used it 3 times within 10 days and my blonde highlights are already cold ash blonde shade. Definitely recommended . Product is pricy but worth the money if you are looking for shampoo which actually does what it says. Hair doesn't feel dry like after some of the other purple shampoos. My one to go to from now on.

Fabulous shampoo , I use it maybe twice a week and it’s definitely brightens my blonde and is a nice tone , it’s expensive but a little goes a long way .

The Olaplex Nº.4P Purple Toning Shampoo is a high-quality product that effectively helps neutralise brassy and yellow tones in blonde, lightened, or highlighted hair. After a few uses, hair looks noticeably cooler and more refreshed in tone. It lathers well and a small amount goes a long way, which makes the bottle last longer than expected. Despite being a toning shampoo, it doesn’t leave hair feeling overly dry, and it actually helps maintain softness and manageability. Hair feels cleaner, smoother, and slightly stronger over time, which is consistent with Olaplex’s reputation for repair-focused formulas. It works well across different hair types, including wavy and curly hair. The only minor downside is that it can be a bit strong if used too frequently, so balancing it with a hydrating shampoo or conditioner is helpful. Overall, a very effective purple shampoo that delivers visible toning results while still caring for hair health.

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.

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.

I’ve been using OLAPLEX No. 4P Blonde Enhancer Toning Shampoo for several weeks, and it has quickly become a staple in my haircare routine. The shampoo is excellent at maintaining blonde tones without leaving the hair feeling dry or brittle. It has a subtle toning effect that gently neutralizes brassy or yellow hues, leaving my blonde hair looking fresh, bright, and vibrant after every wash.The formula is luxurious and feels nourishing from the first application. It lathers nicely and rinses out easily, leaving the hair soft, smooth, and manageable. I’ve noticed that my hair feels healthier overall — less frizz, more shine, and better texture, which is especially important for chemically treated or bleached hair. It pairs perfectly with the OLAPLEX No. 5 conditioner for a full care routine.The scent is pleasant and sophisticated, not overpowering, and the 250 ml bottle lasts a decent amount of time even with regular use. I also appreciate that OLAPLEX focuses on hair health, using ingredients that repair and strengthen while cleansing, rather than just masking colour issues.Overall, this shampoo is fantastic for anyone with blonde, bleached, or highlighted hair. It enhances colour, improves hair texture, and keeps hair healthy and vibrant. It’s a premium product that delivers visible results, and I would highly recommend it to anyone serious about maintaining their blonde tones and hair health.

This is a great shampoo immediately removes yellow tones on blonde hair would definitely recommend and buy again.

My case is particularly bad because I dyed my hair red last year and it's been incredibly stubborn to get it out. I've had foils done on two separate occasions to cover it but it still shows through. Hence why I bought this product.So I didn't notice a difference after my first use, however it did make my hair feel wonderfully soft so I decided to take it on holiday with me. I started to notice a difference in the tone of my hair after using it 3 or 4 times, I was really pleased.However, a week into the holiday I got into a lift and my boyfriend asked me what the hell I'd done to my hair, the shampoo hadstained it quite severely, particularly the over processed bleached strands. It was particularly noticeable in certain lighting (the attached pic was taken mid-flight) including natural light.Thankfully, I managed to wash it out with my regular cheap shampoo when I got home, the stain faded and the toning effect remained which I was pleased with.I would consider repurchasing this product, i might see if I can separate out the bleached, over processed strands next time to avoid them being stained. The last pic was taken after I'd washed the stain out.

Amazing

É bem pigmentado e depois do uso eu sinto meu cabelo um pouco seco.

Muy buen producto para pelo gris con canas

The expiry dates shown in 2022 and one side of bottle seems leaked with the shampoo stain.
