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

Product Information

In middle school, at the height of “blonde jokes,” I often rolled my eyes at obnoxious classmates and responded, “I’m barely blonde.” My hair has pretty much always teetered between brunette and blonde, save a recent natural transition to the darker side. I’ve never dyed my hair and I use a curling iron maybe once a week. There’s not much to it. But thanks to my general apathy, my hair remains considerably healthy. Think of it this way — if you’re dying your hair blonde, investing in products that protect your hair color should feel like a no-brainer. I’d heartily recommend this to anyone looking to stretch out time between salon visits, or just feel like they’re actively working to preserve their color. Even if your hair isn’t dyed, I’d recommend any of Olaplex’s offerings to keep it healthy and free from environmental or styling damage. If your hair tends to get lighter in the sun, this would be a great option to keep those tones as light and bright as you want, for as long as possible. This shampoo is definitely for you if you’re struggling with brassiness — blonde, gray, or otherwise. 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.

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. 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. 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.On the spectrum of brunette to blonde, my hair did seem to be teetering closer to the latter. A few more washes under my belt, I noticed a shine I’d never seen from my hair before. Brushing was a breeze and I couldn't sense any product buildup on my scalp or film on my strands of hair. Two weeks later and my hair is still somewhere between the two colors, but I can see the nuances of my natural color more clearly — the blonde tones are definitely more luminous, and there’s more dimension and luster compared to my typical end of summer dullness. Would I Recommend This Product?

We are so grateful for your support and cannot wait for you to experience the latest additions to the Olaplex Product family! 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! Olaplex is safe for all hair types, gentle, non-toxic, pH balanced, paraben free, color safe, vegan, sulfate free, cruelty-free, and SLS/SLES free. 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 What hair looks healthier than shiny smooth hair? 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.

What This Purple-Tinted Shampoo Can Really Do

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.
