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. 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. 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. We are so grateful for your support and cannot wait for you to experience the latest additions to the Olaplex Product family!

Step 3: Rinse fully. Follow with No.5 Bond Maintenance Conditioner, or No.8 Bond Intense Moisture Mask for extra hydration. 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? 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.

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. 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!

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.

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. 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. 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.Nº.4P repairs, cleanses, and tones with patented OLAPLEX technology for all blondes, lightened, and grey hair.

The longer you treat, the brighter the toning results, but we recommend starting with one minute and going from there.
