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

Product Information

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 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. 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. 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.

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. 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. Acai Berry Extract, a superfood high in antioxidants, also promotes healthy hair by strengthening each strand from the roots. It improves hair health and promotes new growth due to Acai’s high protein content, omega-3, 6 and 9 fatty acids as well as vitamins A, C, E and B. The berries also contain folic acid and zinc which help make hair roots stronger while promoting scalp health. The magnesium in these berries helps to control hair shedding as well.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.

We just launched the newest addition to the OLAPLEX family, Nº.4P Blonde Enhancer Toning Shampoo. 1 in 3 women have blonde hair, whether naturally or salon enhanced. Thanks to OLAPLEX, many of those blondes are healthy. When creating a new product, we thought, how do could we improve every step of the clients’ at-home care, which until now, hasn’t included color. Say hello to our first foray into color, Nº.4P!

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. Admittedly, the levels of this particular ingredient aren’t as high in this formula as in the salon-only treatments—but every little helps when you consider that the oxygen molecules in peroxide attach themselves to bonds and deplete the hair's protein, leaving it brittle.What's more, like all Olaplex products, No. 4P Shampoo is both vegan and cruelty-free, as well as containing no formaldehyde, sulfates, parabens, phosphates, or phthalates. Application—How to use the Olaplex No.4P Purple Shampoo 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 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.

Their products help repair all types of chemical damage, like relaxing and keratin treatments, as well as perms and colouring. If you’ve managed to avoid the bleach but still have damage from heat styling, brushing or even environmental stressors, the Olaplex products are still suitable for you. 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. 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).
