Olaplex Product Ingredients

Olaplex provides tons of scientific evidence to back up its claims about its patented ingredients. Still, you should analyze the ingredients yourself to verify the validity of these claims.

To make the process easier for you, we’ve done an in-depth analysis of Olaplex’s ingredients to help you decide if their products are a good fit for your hair type.

The Good Ingredients

Here are the good ingredients found in Olaplex’s award-winning products.

  • Bis-Aminopropyl Diglycol Dimaleate – This is the main ingredient found in all Olaplex products. It is the foundation of the bond repairing system the brand is famous for. This ingredient repairs hair on a molecular level by repairing disulfide bonds to restore hair’s strength, shine, and texture. 
  • Sodium Lauroyl Methyl Isethionate – This cleansing agent is used in Olaplex’s shampoo. It is a milder alternative to harsh sulfates and surfactants that rob the hair of its natural moisture. Moreover, it produces a creamy lather and allows you to cleanse your hair without damaging its protective layers.
  • Glycine – This powerful amino acid has numerous benefits for hair, including accelerated growth, increased protein production, and enhanced strength. It also boosts collagen production for a healthy, nourished scalp. Glycine is found in Olaplex’s bond intense moisture mask.
  • Isohexadecane – This emollient is used in Olaplex’s bond smoother to condition the hair. It boosts the gloss and smoothness of hair and makes detangling easier. Additionally, it is lightweight and won’t leave residue on the hair like other conditioning agents.

The Bad Ingredients

Here are the bad ingredients you’ll want to watch out for in Olaplex’s products.

  • Dimethicone – This silicone is used in several Olaplex products to create a moisture-sealing barrier around hair strands. Although this ingredient does exactly what it’s designed to do, the residual effects are harmful to your hair. Because dimethicone is waterproof, it will eventually leave a waxy buildup that requires heavy cleansers to remove.
  • Isopropyl Alcohol – This ingredient is used in many hair products to increase the absorption of other substances into the hair. It also helps products dry more quickly. But this alcohol can be severely drying to the hair, making strands weak and brittle.
  • Hexyl Cinnamal – This chemical is commonly used in Olaplex’s products as a fragrance. It is known to cause contact allergies when applied to the skin. Additionally, it can cause irritation such as rashes, bumps, or itching.
  • Polyethylene Glycols (PEGs) – PEG’s are used in Olaplex products to make them thicker and easier to apply. Some PEGs contain impurities such as ethylene oxide, a known carcinogen and respiratory irritant. Over time, exposure to PEG’s can cause damage to the nervous system.

Though Olaplex boasts some fantastic reparative ingredients, it’s essential to be aware of the not-so-great ingredients that are also present.

To make this step in the decision-making process easier, we’ve analyzed verified customer reviews. Based on online reviews, a highly credible source, each one of Olaplex’s products received 4 out of 5 stars.

This shows that the brand has lived up to the bold claims it has made over the years. In addition, professional stylists, everyday naturals, and even celebrities have added Olaplex to their ongoing hair care regimen.

Is Olaplex Bad for Your Hair?

No, Olaplex is not bad for your hair. We believe it is one of the best hair product brands on the market for those with unhealthy natural hair.

Though some of the products contain potentially harmful ingredients, they are unlikely to cause significant harm to your hair. But if the potentially harmful ingredients we discussed earlier alarm you, you can always pass on the products containing these substances.

As an alternative, you can also talk to a stylist or dermatologist in your area before you begin using any Olaplex products.
