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

Product Information

The ingredient line up in a single bottle of No.4 makes the shampoo a one-stop shop for a well rounded, healthy, hair care ritual starting with Olaplex’s patented ingredient, Bis-Aminopropyl Diglycol Dimaleate. Olaplex developed and patented Bis-Aminopropyl Diglycol Dimaleate which became the first ingredient of it’s kind in the new bond builder category. This innovative ingredient protects, nourishes, and restructures hair internally. 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. Inspired by salons, proven by science. No.4P Blonde Enhancer Toning Shampoo combines a high amount of pigment concentration with our patented bond-building technology and mild surfactants to provide a highly concentrated purple shampoo to deliver 3X brighter results (compared to top brands), yet gentle enough for frequent use (we recommend 2-3x weekly). 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.

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 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.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. Ever since, I’ve religiously highlighted my hair every three months.Few feelings beat stepping out of a salon root-free, but it can be short-lived if you live is in a hard-water area (like me). Minerals and metals penetrate blonde hair, which tends to be more porous, and warm tones creep in. I’m already a big fan of Olaplex, as the in-salon treatments have resuscitated my bleached strands, while Olaplex No.3 Hair Protector has been a part of my weekly regime for years—so, naturally, I was intrigued by the No4.P Shampoo. A beauty editor's honest review of Olaplex No.4P Blonde Enhancer Toning Shampoo Ingredients—What's in the Olaplex No.4P Purple Shampoo?

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.
