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.

No.0 is an intensive repair booster that absorbs deeply into the hair. It’s designed to work in tandem with No.3 in order to receive the intense repair. While No.3 Hair Perfector can be used on its own, we do not recommend using No.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. No.0 is a watery liquid that will dry quickly. Using No.3 over it, keeps the hair damp so both products can continue to work during the process.

No. No.0 needs to fully absorb into the hair for at least 10 minutes. This allows the No.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 No.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 the OLAPLEX No.0 and OLAPLEX No.3 in longer! However, the efficacy will diminish past 30-45 minutes or when the hair is dry. 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 No.3: Apply to damp / towel-dried hair, apply a generous amount of No.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. However, we have received great feedback from people who have used it this way.

OLAPLEX No.3 reaches its max efficacy at 30-45 minutes however OLAPLEX is actively working in the hair as long as the hair remains moist.

Generally, no, you do not need to shampoo before using No.3. However, if you have a lot of product on your hair, it is always a good idea to cleanse the hair before your treatment. Use your best judgment.

Yes, each OLAPLEX product is free of sulfates, phthalates, DEA, aldehydes, formaldehyde, gluten, parabens and safe for all hair!

Yes, the No.4 shampoo and No.5 conditioner are both formulated for daily/ every wash use!

Yes, the No.4 shampoo and No.5 conditioner are both formulated for daily/ every wash use!

No.6 can be applied to both damp and dry hair and can be both air dried or blow-dried into the hair.

Olaplex No. 6 can be used daily on wet and dry hair, however, the effects of No. 6 work up to 72 hours so you shouldn't need to use it daily unless you wash and condition your hair daily.

Olaplex No.6 does contain heat protection for use when blow-drying hair but is not rated for 450 degrees. We suggest using a separate heat protectant along with No. 6 when using any other heat styling tools on your hair.

Yes! Every hair type can benefit from deep hydration, plus additional repair. It’s a luxurious part of weekly self care for your hair.

Nº.8 is meant to be used as often as needed to rebalance the moisture in the hair. You cannot overuse Olaplex Nº.8 and many people do use it as often as every wash

Nº.3 Hair Perfector is not a mask or a conditioner; it works inside the hair structure to relink broken bonds. Nº.8 Bond Intense Moisture Mask is a deep conditioning mask that repairs & hydrates the hair. Both can be used on a weekly basis to strengthen & repair the hair.

Yes, you can leave Nº.8 in longer than the recommended amount of time. You cannot overuse Nº.8

You can, though your hair will not benefit from the full potential of the treatment by cutting time down.

Nº.5 is meant to be used as your daily conditioner providing the hair with the main components of a conditioner as well as the repair from the active ingredient. Nº.8 takes it a step further providing the hair with extra moisture while being lightweight and leaving the hair healthy with body and fullness as well as including the repair from the active ingredient.
