Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.
So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.
You'll also recognize water as that liquid we all need to stay alive. Talk about multi-purpose! If you see this, drink a glass of water. Stay hydrated!

Olaplex No.6 Bond Smoother contains this as ingredient number 1.
This ingredient is a preservative, antimicrobial, and emulsifier. It is often used in cosmetics for its ability to cleanse, condition, and reduce static.
Cetrimonium chloride is a quaternary ammonium salt, meaning it has a water-soluble structure.
The INKEY List PCA Bond Repair Hair Treatment contains this as ingredient number 7.
Olaplex No.6 Bond Smoother contains this as ingredient number 13.
Panthenol (also referred to as pro-vitamin B5) is a common ingredient that helps hydrate and soothe the skin.
lt is a humectant, meaning that it helps the skin attract and retain moisture.
Another benefit is the anti-inflammatory abilities. This means that it's great for sensitive, irritation-prone skin.
Once oxidized, panthenol converts to pantothenic acid. Panthothenic acid is found in all living cells.

Olaplex No.6 Bond Smoother contains this as ingredient number 41.
Sodium Benzoate is a preservative. It's used in both cosmetic and food products to inhibit the growth of mold and bacteria. It is typically produced synthetically.
Both the US FDA and EU Health Committee have approved the use of sodium benzoate. In the US, levels of 0.1% (of the total product) are allowed.
Sodium benzoate works as a preservative by inhibiting the growth of bacteria inside of cells. It prevents the cell from fermenting a type of sugar using an enzyme called phosphofructokinase.
Sodium Benzoate is the salt of benzoic acid. Foods containing sodium benzoate include soda, salad dressings, condiments, fruit juices, wines, and snack foods.
Studies for using ascorbic acid and sodium benzoate in cosmetics are lacking, especially in skincare routines with multiple steps.
We always recommend speaking with a professional, such as a dermatologist, if you have any concerns.

Olaplex No.6 Bond Smoother contains this as ingredient number 36.
Potassium Sorbate is a preservative used to prevent yeast and mold in products. It is commonly found in both cosmetic and food products.
Potassium sorbate is potassium salt derived from sorbic acid. Sorbic acid is a natural antibiotic and effective against fungus.
Potassium sorbate and sorbic acid can be found in baked goods, cheeses, dried meats, dried fruit, ice cream, pickles, wine, yogurt, and more.
Potassium sorbate is often used with stronger preservatives.

Olaplex No.6 Bond Smoother contains this as ingredient number 33.
Citric Acid is an AHA derived from citrus fruits (think oranges, lemons, and limes!).
If you spot Citric Acid near the end of an ingredient list, it's likely there as a pH adjuster rather than an active ingredient.
As an AHA, Citric Acid removes the top layer of skin cells from the newer layer of skin underneath. This helps skin to remove dark spots and look more even.

Olaplex No.6 Bond Smoother contains this as ingredient number 42.
Phenoxyethanol is a preservative that has germicide, antimicrobial, and aromatic properties. Studies show that phenoxyethanol can prevent germ and microbial growth. By itself, it has a scent that is similar to that of a rose.
It's often used in formulations along with Caprylyl Glycol to preserve the shelf life of products.
