We are so grateful for your support and cannot wait for you to experience the latest additions to the Olaplex Product family! Firstly, we’ve got to explain what makes Olaplex so special and why we need their bond maintenance treatments in our lives. 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. 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?

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. Highly concentrated formula neutralizes unwanted yellow tones while strengthening and softening hair 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 ShampooEver 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? 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? Follow with Nº.5 Bond Maintenance Conditioner for everyday moisture or Nº.8 Bond Intense Moisture Mask for Extra hydration. 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.

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.

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.Water (Aqua/Eau), Sodium Lauroyl Methyl Isethionate, Cocamidopropyl Hydroxysultaine, Potassium Cocoyl Glycinate, Disodium Cocoyl Glutamate, Sodium Lauroyl Sarcosinate, Potassium Cocoate, Decyl Glucoside, Glycereth-26, Bis-Aminopropyl Diglycol Dimaleate, Cocamidopropylamine Oxide, Disodium Laureth Sulfosuccinate, Glycol Distearate, Sodium Cocoyl Glutamate, Methyl Gluceth-20, Acrylates Copolymer, PEG-120 Methyl Glucose Dioleate, Amodimethicone, Citric Acid, Sodium Lauryl Sulfoacetate, Polyquaternium-10, Ethylhexylglycerin, DivinylDimethicone/Dimethicone Copolymer, Polyquaternium-11, Trisodium Ethylenediamine Disuccinate, Guar Hydroxypropyltrimonium Chloride, C11-15 Pareth-7, Laureth-9, Glycerin, Trideceth-12, C12-13 Pareth-23, C12-13 Pareth-3, Hydrolyzed Vegetable Protein, PG-Propyl Silanetriol, Panthenol, Acetic Acid, Tetrasodium EDTA, Pentasodium Triphosphate, Sodium Hydroxide, Disodium EDTA, Helianthus Annus (Sunflower) Seed Oil, Tocopherol, Prunus Armeniaca (Apricot) Kernel Oil, Pseudozyma Epicola/Camellia Sinensis Seed Oil Ferment Extract Filtrate, Pseudozyma Epicola/Argania Spinosa Kernel Oil Ferment Filtrate, Quaternium-95, Propanediol, Helianthus Annus (Sunflower) Seed Extract, PEG-8, Euterpe Oleracea Fruit Extract, Punica Granatum Extract, Rosemarinus Officinalis (Rosemary) Leaf Extract, Musa Sapientum (Banana) Fruit Extract, Origanum Vulgare Lear Extract, Morinda Citrifolia Fruit Extract, Articum Lappa Root Extract, PEG-8/SMDI Copolymer, Sodium Hyaluronate, Palmitoyl Myristyl Serinate, Sodium Polyacrylate, Pentaerythrityl Tetra-Di-T-Butyl Hydroxyhydrocinnamate, Biotin, Benzoic Acid, Phenoxyethanol, Chlorphenesin, Potassium Sorbate, Sodium Benzoate, Fragrance(Parfum), Citral, Hexyl Cinnamal, Limonene Both are scientifically proven to prevent the disulfide bonds in your hair from breaking during the coloring process by effectively ‘gluing’ them together.
