OlaplexNo. 4P Blonde Enhancer Toning Shampoo, 250 ml (Pack of 1)

If I want to give my grey hair a bit of a tint or vibrancy then this is my go to shampoo. Leave it on for a little longer and my hair has a beautiful tone to it.

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.

excellent product - you get what you pay for!

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.

After my hair being over processed at the hair dressers 7 weeks ago I finally caved in and decided to invest in a couple of the Olaplex products.I was extremely sceptical after reading the reviews but with my hair snapping as badly as it was and me spending the last 7 weeks crying because of how thin, tangled and dry it was getting I was willing to loose the money should the products not work.For the last 7 weeks I have been using bed head products and a coconut oil (these have always been my hair products and have never failed me!) but the damage caused to my hair was too much for these this time around!I was literally waking up in a morning with a pillow full of small snapped hair, washing my hair was horrendous, I had crazy snapped hair sticking up on the top of my scalp! … well… I decided to buy just the Olaplex no 5 to start with, I used my resurrection bed head shampoo to remove the oils I’d used during the day and left the no 5 conditioner on my hair for around 30 mins, I instantly and on my life saw a change from there!I was able to get a brush through my wet hair with out tangling, I allow my hair to dry naturally until slightly damp then I finish off with the hair dryer… prior I was covered in hair … after the one time use of the no 5 I honestly did not have one single hair on me … I can’t stress how happy that made me! 😩… any way! Back to the no 4p … I received this tonight, I instantly had the shower going, washed my hair as per with my bed head shampoo, applied the 4p to damp hair and left it on for 15 mins, after I applied the no 5 (just as a precaution really)… I left that for around 3 mins to do its magic, dried my hair as per (air dry until slightly damp then finished with the hair dryer) … again, no hair loss, no tangling, and a much nicer colour! I was absolutely gob smacked at the difference… I already have no fly always at the top of my head, my hair feels much stronger and although it’s not as thick as it use to be I’m absolutely certain that with continued use of these products it will be back to its healthy self in no time.I have just gone on to order no 0, no 3 and no 7My new hair routine will now be - no 0, no 3, no 4p, no 5 then no 7 and I will do this twice weekly ! I have full faith 🙏 (the above order is apparently really good for damaged, over processed blonde hair if any one is wondering)With the no 4p - a little really does do a lot! I Literally used an amount that would equate to the size of a 50 pence piece … and yes, yes it does stain your hands, I thought I was clever by scrubbing straight after … that does not remove it 😂 … I’m going on a bit now so I’ll wrap it up, this stuff really is good … & I will neverrrrr stray from it with these results … (the first pic was from around a week ago… the second pic was straight after blow drying this evening- one use of no 4p - no filters) … this product - highly recommended!
