Our mission is to ensure that every user of our products has healthier and stronger hair. OLAPLEX uses state of the art testing to determine product safety and efficacy. OLAPLEX also complies with good quality assurance practices; meets industry standards in formulation, manufacturing and testing; and utilizes contract manufacturers that comply with Good Manufacturing Practices (GMP)—a system for ensuring that products are consistently produced and controlled according to quality standards. OLAPLEX tests its products before they go on the shelf and re-tests products as necessary to ensure safety and effectiveness. If a user of OLAPLEX products is not satisfied with his or her purchase, we want to hear from them.

We take pride in developing products that are scientifically proven to improve hair health, not harm it. Our products are tested at our R&D facility and by independent third parties and there is no evidence from that testing that OLAPLEX products or their ingredients are capable of causing hair loss or hair breakage.

There are many possible contributing factors to hair loss, including diet, stress, health concerns, pregnancy and pharmaceutical use. Anyone experiencing consistent hair loss should consult a dermatologist to best understand their unique hair and skin needs.

No. OLAPLEX was founded to revolutionize science-backed solutions for healthy, stronger hair. However, we understand that losing hair in any amount can be stressful, which is why we follow strict quality control processes and test our products before they go on the shelf and re-test products as necessary to ensure that they are safe to use.

Experiencing hair loss or hair breakage is a difficult and painful experience, and we are sympathetic to anyone in that position. We remain confident in the evidence showing that OLAPLEX products are safe and effective. We recommend that anyone who is experiencing consistent hair loss or hair breakage consult with a dermatologist to best understand their unique hair and skin needs.

Our third-party laboratory partners run a series of rigorous safety and clinical tests on both skin and hair to ensure all OLAPLEX products are safe and effective.

For example, before our products are made publicly available, we conduct a human repeat insult patch test (HRIPT), which is the standard human clinical test used for personal care and pharmaceutical products and tests for irritation and sensitization. Further clinical testing is done on hair itself to measure the response and effectiveness of our products to fortify hair and rebuild broken bonds at the molecular level.

All products go through rigorous testing before being made available to the public, and we conduct additional testing as needed.

We provide the results of our human repeat insult patch tests (HRIPT), which are the standard human clinical test used for personal care and pharmaceutical products and test for irritation and sensitization. The results of those tests can be found here.

In addition, we provide ingredient labeling and safety data sheets for each of our products, which are available here.

Yes. OLAPLEX utilizes third-party owned and operated factories to manufacture our products, all of which comply with Good Manufacturing Practices (GMP). GMP ensures that products are manufactured according to the highest standards for safety and quality control in the industry. As part of their compliance with GMP, our contracted factories must conduct industry-standard testing of their facilities prior to manufacturing every new batch of a product. This testing ensures that there are no environmental micro contaminants present during the manufacturing process, and our factories are required to retain the results of these tests for quality assurance.

We are proud that all of the human repeat insult patch tests (HRIPT) conducted show that OLAPLEX formulas are safe. The test results show no indication of a potential to elicit dermal irritation or sensitization, otherwise known as a contact allergy.

Specifically, OLAPLEX No. 2 and No. 3 were tested on 80 human test subjects and showed zero irritation. OLAPLEX No. 1, 4, 5, 6, 7, 8 and 9 were tested on over 100 human test subjects and showed zero irritation.

OLAPLEX No. 7 was tested on 112 test subjects and one test subject showed minor edema, or swelling, during the second read out of 12 total readings conducted over the course of a five week-long study. The edema was cleared by the third read out and did not return for the remainder of the study.

In addition, HRIPT tests were performed on individuals with sensitive skin for OLAPLEX No. 0, 3, 4 and 5. These tests were conducted on 51 people and showed no indication of a potential dermal irritation or sensitization.

OLAPLEX begins repairing hair bonds upon first use! OLAPLEX’s patented ingredient, Bis- Aminopropyl Diglycol Dimaleate, is designed to target the millions of disulfide bonds within our hair that give it structure and stability. These bonds can be damaged or broken in numerous ways, including heat from styling tools, color and chemical treatments, brushing, environmental factors and the natural aging process. Users of OLAPLEX can protect their hair and expect visibly healthier, stronger and more vibrant hair.

All OLAPLEX products are labeled with instructions for recommended use. It is not possible to “over bond” hair when using OLAPLEX products as instructed.

OLAPLEX’s products work to protect hair and relink existing bonds, not create new ones. As bonds constantly face damaging forces like heat from styling tools, color and chemical treatments, brushing, environmental factors and the natural aging process, they need to be strengthened on a continuous basis. Everyone has broken hair bonds to some extent! Even if you have healthy hair, you will have some level of damage that OLAPLEX would be able to repair.

OLAPLEX offers professional grade products only approved for salon use, including our Nº.1 and Nº.2 products, which use OLAPLEX’s patented formula to rebuild broken bonds to strengthen the hair. In addition, OLAPLEX’S 4-In-1 is an in-salon mask that protects hair while adding intense moisture, shine, smoothness and body. OLAPLEX’s salon-grade products are highly concentrated in order to provide the most optimal results. However, this high concentration means that these products should be handled and applied by expert stylists who have knowledge of the science behind OLAPLEX and understand the unique needs of every individual’s hair. Olaplex offers and encourages professional stylists to become certified in use of the Olaplex professional products. In order to be certified, a stylist must study a product knowledge training manual and pass a test.

OLAPLEX products work on extensions that are 100% human hair. The bonds in human hair used for extensions can be damaged just like the hair on our heads, and OLAPLEX’s products are scientifically formulated to penetrate and repair hair from the inside out by rebuilding broken bonds at the molecular level.

When treating extensions with any products, OLAPLEX or otherwise, we recommend testing the product on a few strands before using it on the full set of extensions. Companies can label extensions as being 100% human hair as long as they contain 80% human hair or more, which can prevent OLAPLEX from being fully effective.

OLAPLEX takes the health and safety of our customers very seriously, and our products are formulated to be safe and effective when used as instructed. Although we cannot speak to the safety and effectiveness of non-OLAPLEX products, we recommend individuals consult their hair stylist for advice on creating a hair care regimen suitable for achieving their desired results, which may include products from different brands.

All OLAPLEX products contain a recommendation on the packaging for how long the product is safe and effective to use after opening. See the image below for where to find this information on your OLAPLEX product (the icon in the green box). Once this time period has passed, the product should be discarded and re-purchased for maximum safety and effectiveness.

Yes. Like most cosmetic products, OLAPLEX should be stored in a cool, dry place away from high temperatures or direct sunlight. Conditions such as prolonged high moisture or heat have the potential to chemically alter the product, causing a negative formulaic reaction.

OLAPLEX products do not contain any plastics. OLAPLEX’s patented ingredient, Bis- Aminopropyl Diglycol Dimaleate, is designed to target the millions of disulfide bonds within our hair that give it structure and stability. Bis- Aminopropyl Diglycol Dimaleate is not a plastic and it doesn’t coat your hair—it is scientifically formulated to fortify hair from the inside out by rebuilding broken bonds at the molecular level.

OLAPLEX products No. 4 and No. 6 contain minimal hydrolyzed vegetable protein, also known as peptides, at very low levels (0.0025% in No. 4 and 0.000625% in No. 6). Our other products do not contain any forms of protein. Peptides such as those in OLAPLEX’s No. 4 and No. 6 are chemically very different than standard proteins, and therefore do not weigh down hair.

Keratin, for example, is a naturally occurring protein in hair and makes up about 95% of hair mass. Haircare products use fragments of keratin to supplement damaged hair keratin and restore the hair’s strength and shine.

OLAPLEX does not currently manufacture or sell products containing lilial. In September 2020, the EU regulatory authority announced their intent to phase out Butylphenyl methylpropional commonly referred to as "lilial" by March of 2022. At OLAPLEX, lilial was previously used in small amounts as a fragrance in N°.3 Hair Perfector and N°.2 Bond Perfector. It is not an active or functional ingredient. While this phase out is limited to the EU, out of an abundance of caution, OLAPLEX proactively removed lilial from our N°.3 Hair Perfector and N°.2 Bond Perfector globally.
