Frequently Asked Questions

Disulfide bonds are in all three main parts of the hair:

• Cuticle • Cortex • Medulla (if the hair has one)

Most people think about how Keratin (proteins) make up the hair, forming polypeptide bonds (long chains) that are kept in alignment by hydrogen, salt and disulfide bonds.

The overall internal structure resembles ladders that have been twisted into a shape resembling a multi-fiber cable called microfibrils. These then combine to form macrofibrils which are contained in the cortex. These “cables” stay in alignment, resisting twisting and bending, as a result of disulfide bonds. They are held together in the cortex with a microcellular cement that also contains an abundance of disulfide bonds.

All hair contains millions of disulfide bonds which give the hair its structure, strength and stability. When all the bonds, especially the disulfide bonds, are intact and in alignment, you have healthy, beautiful, shiny, touchable hair. When disulfide bonds are broken, it results in damage.

Hair is damaged daily. Split ends, frizz, lackluster Color, thinning and dryness can all be related to broken disulfide bonds.

• Flat irons, curling irons, and blow dryers all cause damage due to the high levels of heat being used.

• Mechanical damage such as brushing, friction, tugging and pulling on wet hair affect the bonds.

• UV damage from the sun, humidity, extreme hot/cold weather conditioners, pollution, etc. all have a negative impact on the hair’s bonds.

• Chemical services can also cause damage. These services include Color, Lighteners, Perms, Relaxers, Keratin Treatments, and Japanese Straighteners/Thermal Reconditioners.

The chemicals and/or thermal tools being used react with the disulfide bonds breaking them and causing protein loss, leaving behind damaged hair. When damage occurs, it affects the disulfide bonds throughout the entire hair fiber.

All hair types (natural, curly, fine, straight, etc.) derive most of their integrity from healthy, properly paired, disulfide bonds. When hair is damaged via thermal, chemical, mechanical or environmental factors, these disulfide bonds are broken apart resulting in single sulfur hydrogen bonds.

What happens after a disulfide bond breaks? There are two reactions that can take place. The first reaction is that the single sulfur hydrogen component pairs with a single oxygen molecule. This makes a perfect pair with no further damage taking place.

The second reaction is where damage occurs. A single sulfur hydrogen molecule will pair with three oxygen molecules creating S03, or what is known as a sulfate group. The protonated sulfate is known as Cysteic Acid. Cysteic acid then eats the protein out of the hair.

In the case of chemical services, OLAPLEX works by pairing with the single sulfur hydrogen bond faster than the three oxygen molecules can.

OLAPLEX is beneficial for all hair types. Whether your hair is Color Treated, Texture Treated, Virgin or anything in between, it is damaged on a daily basis. OLAPLEX assists in both preventing that damage and repairing it, returning the hair to a virgin like state. OLAPLEX is compatible with all manufacturers chemical service products. Your hair is an investment, and the only accessory that you never take off. In fact, it’s the only thing short of plastic surgery that can change the way you feel about yourself. Everyone wants beautiful, healthy, manageable shiny hair and with OLAPLEX, that can become a reality!

VIRGIN HAIR

OLAPLEX is great for virgin hair. It helps to repair existing damage while protecting it from thermal, mechanical and environmental damage. OLAPLEX strengthens and prepares the hair for future services.

COLOR TREATED HAIR

OLAPLEX can be mixed into all Colors and Lighteners to lessen the damage caused by these services. OLAPLEX is also used to maintain and repair Color Treated hair for healthy, beautiful looking hair.

CURLY AND NATURALLY TEXTURED HAIR

OLAPLEX rebuilds, restructures and improves moisture retention to curls that have lost their shape. OLAPLEX infuses curly hair with added moisture and condition for beautiful bouncy, resilient curls. Fragile curly hair has more lightening and chemical service options when OLAPLEX is used.

STRAIGHT HAIR

OLAPLEX will strengthen straight hair, improving manageability, movement and shine. The condition of the hair won’t be compromised using thermal styling options such as curling irons, hot rollers, etc. when the hair is treated prior with OLAPLEX.

TEXTURE SERVICES (PERMANENT WAVES, RELAXERS, THERMAL STRAIGHTENING/RECONDITIONING)

OLAPLEX helps to maintain the integrity of the hair before, during and after all texture services. Texture services last longer, and the hair stays in better condition when OLAPLEX is used correctly. Damage-free Color and Lightening Services performed after any texture service are possible when properly using them with OLAPLEX.

EXTENSIONS

OLAPLEX can be used on all 100% human hair extensions. Some extensions have a Keratin coating on them which can sometimes act as a barrier to the OLAPLEX Treatment. Extensions sometimes are treated with textile dyes which can lead to unpredictable results with Color or lightening. With any type of glued in or taped in extensions, we recommend keeping OLAPLEX off those areas to avoid possibly loosening them. When in doubt, always perform a Strand Test on extensions as results may vary.

We do not recommend using BROWBOND™ on potentially irritated skin (that can be caused by brow coloring or lamination?).

We recommend that skin treated with microblading is completely healed before using BROWBOND™. Do not use BROWBOND™ on skin damaged by microblading.

Use twice daily, AM and PM, on clean, dry skin. Do not rinse off. Allow to dry for at least 90 seconds before applying any other brow products.

BROWBOND™ is dermatologist-tested, ophthalmologist-tested and safety-tested, and was proven to be non-irritating to skin. If irritation occurs, discontinue use.

With 2x daily use, BROWBOND™ will last 3 months.

Immediately after use, your brows will appear shaped, sculpted and more defined. In as little as 4 weeks, brows will look thicker, denser and more full.

Your eyebrows will return back to their natural growth cycle.

The unique doe-foot applicator with a micro-bristle brush allows for a more even and precise application to brows

No! BROWBOND™ is fragrance-free.

This clear, lightweight, eyelash-enhancing serum promotes the appearance of thicker, longer, stronger, full-volume lashes and contains:

• OLAPLEX Peptide Complex Technology™- a proprietary blend of peptides, including an OLAPLEX-exclusive peptide that supports the look of longer, thicker, stronger, and fuller lashes.
• Our exclusive OLAPLEX Bond Building Technology™ supports the skin barrier at the lash line.
• Hyaluronic Acid promotes hydrated, healthy-looking lashes and reduces the appearance and feel of dry, brittle lashes.

OLAPLEX’s LASHBOND™ Building Serum is drug-free and ophthalmologist tested for safety, eye color and skin pigment safe, and non-irritating. In addition to the industry standard human repeat insult patch testing (HRIPT) to test for any potential irritation or sensitization issues, LASHBOND is also ophthalmologist tested. This testing includes two primary forms of testing and analysis, the first being a periocular tolerance test which assesses the irritation potential of a topical product applied on the eye contour area. The second is an ocular irritation test which uses a 3D model of eye tissue to determine the potential of a cosmetic product or ingredient to cause eye irritation when used by the consumer.

In a 12-week clinical trial of 33 people using LASHBOND™ Building Serum, participants reported the following after four weeks:

• 94% experienced more voluminous-looking lashes
• 97% reported improvement in the appearance of denser lashes
• 97% reported improvement in the appearance of longer lashes
• 100% reported improvement in the appearance of thicker lashes*

*Results may vary. As reported by participants after 4 weeks in a consumer perception clinical study of 33 subjects with 2x daily use.

We clinically tested it for use on eyelashes only and recommend following the intended product usage and instructions. In addition, we recommend only applying the product directly to the upper lash line, as the product migrates on its own through the action of blinking, so it's best not to apply directly on the lower lash line.

We recommend applying this product 2x a day. This recommendation is based on the protocol for our clinical studies and provides optimal efficiency. For the product to work its best, we recommend consistent application for stronger results.

Some of our clinical study participants saw positive results as early as two weeks.

N.°0 is an intensive repair booster that absorbs deeply into the hair. It’s designed to work in tandem with N.°3 in order to receive the intense repair. While N.°3 Hair Perfector can be used on its own, we do not recommend using N.°0 alone.

Yes, it will provide some repair, but is designed to work as a two-part process.

OLAPLEX technology works best when the product is wet in the hair. N.°0 is a watery liquid that will dry quickly. Using N.°3 over it, keeps the hair damp so both products can continue to work during the process.

No. N.°0 needs to fully absorb into the hair for at least 10 minutes. This allows the N.°3 to be pulled deeper within the hair structure.

All hair types & textures will benefit from this. More intensely damaged hair will see the most dramatic results at first. The more often N.°0 is used, the healthier the hair becomes. Results may not be as noticeable, but it is still working within the hair structure.

You can leave OLAPLEX N.°0 and OLAPLEX N.°3 in for 10 minutes. Rinse, shampoo & condition for best results.

Yes! You can use N°.3 even if you have not tried the salon treatment yet. This is because the entire OLAPLEX line shares the same active ingredient to repair broken bonds in the hair.

N°.3 Hair Perfector is formulated for at-home care and maintenance. When used alone without the in-salon treatment, OLAPLEX N°.3 acts as a mini treatment.

For best results with N°.3: Apply to damp / towel-dried hair, apply a generous amount of N°.3. Comb through and let process for a minimum of 10 minutes. Then shampoo and condition!

As a company, we do not recommend sleeping in OLAPLEX treatments as it could get into your eyes.

You can leave OLAPLEX N.°3 in for 10 minutes. Rinse, shampoo & condition for best results.

Yes. N°.4D CLEAN VOLUME DETOX DRY SHAMPOO does not contain silicones.

No–to ensure product safety, we submitted N°.4D Clean Volume Detox Dry Shampoo to an independent, third-party lab to test for the presence of benzene. Benzene is a chemical byproduct of some product manufacturing, especially of many aerosols such as deodorants and dry shampoos. The results of our third-party testing show that benzene is not detected in N°.4D down to 0.1 parts per million (ppm). Your safety is our top priority, and we will continue to maintain rigorous health standards for all OLAPLEX products.

Sodium benzoate is a safe and effective preservative. This ingredient is unrelated to benzene. N°.4D CLEAN VOLUME DETOX DRY SHAMPOO has been tested for benzene. No benzene was detected.

Yes, it can be used on all hair types and textures, wigs, and extensions.

N°.4D is designed to absorb any oil/sebum that is released from the scalp and to capture environmental deposits. The number of days the hair stays clean depends on the amount of oil/sebum production and the amount of environmental deposit.

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.

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 above and beyond industry standards on both skin and hair to ensure all OLAPLEX products are safe and effective. In addition, our products are regulated by the FDA, which is the U.S. government agency responsible for enforcing compliance with the regulations that govern cosmetic products in the U.S.

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. 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 numerous rounds of testing before being made available to the public. We conduct additional periodic 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.
