No.4 has that covered too with Vitamin E, Apricot Kernel Oil, Pomegranate Seed Oil, and Fermented Argan Oil. Rich in Vitamins A & E, Omegas 6 & 9, these ingredients help increase shine, giving the hair a silky texture. The vitamins also add a protective layer to the hair for enhanced manageability and shine. The best-selling shampoo from Olaplex® is now formulated to celebrate the beauty of blonde. Olaplex® No.4-P Blonde Enhancer Toning Shampoo strengthens, softens, and neutralizes unwanted yellow tones for brighter, more manageable hair. Olaplex® No.4-P maintains all the benefits of the original No.4 and deposits just the right amount of tone to neutralize any unwanted warmth between salon visits. The sulfate-free, highly concentrated formula allows for customizable toning - The longer you treat, the brighter the results. Whether your blonde comes naturally or from your stylist, root to tip or balayage, and even if you’re proudly grey, Olaplex® No.4-P Blonde Enhancer Toning Shampoo will help to keep your color bright. Basically, over styling and hair stressors can break the strong disulphide bonds in the hair. These bonds are necessary for a healthy-looking ‘do. This breakdown then creates a single sulphur hydrogen bond which can pair with three oxygen molecules. If this happens it produces cysteic acid which can eat away at the protein in your hair. This is bad news for our beautiful tresses!

Highly concentrated formula neutralizes unwanted yellow tones while strengthening and softening hair What is it? The latest and greatest from Olaplex. This weightless, leave-in, silicone-free hair serum shields hair from pollution for 48 hours and provides heat protection up to 450°F. Firstly, we’ve got to explain what makes Olaplex so special and why we need their bond maintenance treatments in our lives. Step 3: Rinse fully. Follow with No.5 Bond Maintenance Conditioner, or No.8 Bond Intense Moisture Mask for extra hydration. Nº.4P repairs, cleanses, and tones with patented OLAPLEX technology for all blondes, lightened, and grey hair. While hydrating, Nº.4P neutralizes brassiness and brightens the blonde. The highly concentrated pigment allows customizable toning levels ideal for medium to light blonde tones (levels 7 and up) in which yellow or brassy tones need to be controlled. Compared to top purple shampoos, users found their hair 3x brighter using OLAPLEX Nº.4P. The longer you treat, the brighter the toning results, but we recommend starting with one minute and going from there.We are excited to release the No.4 and No.5 just around the corner after 2 years of formulating from our chemists. The results have been amazing and I can’t wait for everyone to experience.” – Dean Christal, Founder of Olaplex

To achieve optimum results from this brightening shampoo, you should follow the instructions on the bottle. It’s also important to do a patch test inside your elbow or behind your ear and wait 48 hours to ensure there's no irritation.Step 2: Apply No. 4P Blonde Enhancer Toning Shampoo to wet hair. Lather and leave to process for one to three minutes. For more intense toning, leave on hair for up to five minutes. Use two to three times a week or as often as needed. Whether you’re guilty of over bleaching your hair or using too much heat styling, we’ve all put our precious strands through the wringer. However, one brand that pops up again and again as the ultimate hair saviour is Olaplex. In fact, it took the number one spot as the hottest hair care brand in our 2022 Hair Report. Both are scientifically proven to prevent the disulfide bonds in your hair from breaking during the coloring process by effectively ‘gluing’ them together. Olaplex also prevents any protein-destroying molecules from ravaging your strands by stepping in before they have the chance to wreak havoc. In short, they're perfect for those who frequently bleach or dye their hair. I also love that you can slot this shampoo into your usual hair care routine. You don’t have to buy a separate conditioner to create a de-brassing "system", you simply follow with your usual No.5 Bond Maintenance Conditioner. Of course, you could use another conditioner if you wish, but I find products from the same brand tend to work in synergy; with Olaplex, this is all the more important, given its unique molecule.

Nº.4P repairs cleanses and tones with patented OLAPLEX technology for all blondes, lightened, and grey hair. While hydrating, Nº.4P neutralizes brassiness and brightens blonde. The highly concentrated pigment allows customizable toning levels ideal for medium to light blonde tones (levels 7 and up) in which yellow or brassy tones need to be controlled. Compared to top purple shampoos, users found their hair 3x brighter using OLAPLEX Nº.4P. The longer you treat, the brighter the toning results. According to clinical trials, hair looks three times brighter after just one use of the Olaplex No.4P compared to other top purple shampoos in the market. But what really sets this particular purple shampoo apart from competitors is that it also contains Olaplex’s patented molecule, bis-aminopropyl diglycol dimaleate. Put simply, this high-tech molecule rebuilds the broken bonds in the hair that result from heat styling, chemical treatments, and (this is a key one in blonde hair) bleaching.You can read more about its benefits in our guide on using Olaplex as a treatment. Apply to wet hair. Lather thoroughly and let process 1-3 minutes. Rinse. For more intense toning, leave on hair for up to 5 minutes. Still not sure what that means? Don’t worry, just know that salons across the globe use Olaplex treatments to achieve soft, shiny, strong and healthy-looking results. Which Olaplex to use?This leads us to our next round of ingredients which help support the strength of the hair, like Fermented Green Tea Oil which prevents split ends and breakage. Heliogenol derived from Sunflower Seed Extract also acts as a hair protectant against damage caused by free radicals and other hair processes or styling. Olaplex isn’t like other hair treatments. While other hair care brands simply smooth over the problem, the Olaplex formula actually repairs the damage using their patented single ingredient Bis-Aminopropyl Diglycol Dimaleate. This works on a molecular level to restore your hair. In fact, it is the only patented bond builder in the biz.
