Olaplex Products Explained: Treatments, Shampoos, Conditioners & More

Having studied the science behind what makes certain products, I’m always intrigued by products that claim to work on a molecular level. Olaplex is one of the few haircare brands that truly lives up to its claims as its technology is grounded in real chemistry. In this guide, we’ll explore the full Olaplex range, from treatments to shampoos, conditioners, stylers, and moisture-boosting serums, so you can find the right products for your hair type and goals.

Founded in 2014 by Dean Christal, Olaplex started with a single patented molecule, Bis-Aminopropyl Diglycol Dimaleate. This compound is designed to repair broken disulfide bonds in the hair which are the internal structure that gives hair strength, elasticity, and shape. When they're broken (by bleaching, colouring, or heat), hair becomes weak and brittle. Olaplex uses click chemistry to rebuild these bonds from the inside out.

Today, Olaplex offers a complete at-home line designed for all hair types, including fine, curly, coloured, and chemically treated hair. The brand is vegan, cruelty-free, and free from parabens, sulphates, and phthalates.

These formulas contain the highest concentrations of the brand’s bond-building technology, targeting the internal structure of the hair to reverse damage from colouring, bleaching, and heat. They’re the backbone of any Olaplex routine, especially for compromised or chemically processed hair.

This is the ultimate pre-treatment primer, designed to boost the effects of No. 3 Hair Perfector. With the highest concentration of Olaplex’s bond-building technology available at home, it preps your hair for deep repair and is most effective when used with No. 3.

As a newer addition to the line, this scalp serum targets inflammation and supports long-term hair health. Formulated with ceramides and peptides, it strengthens the scalp barrier and promotes a healthy environment for future growth and is suitable for all hair types.

This weekly repair treatment is a pre-shampoo and visibly improves hair texture, strength, and shine. It’s a bond-builder that works on a molecular level to reverse damage from heat, colouring, and styling.

Cleansing is a critical first step in haircare, but many shampoos strip the hair of moisture and essential proteins. Olaplex shampoos are different as they not only clean the hair and scalp effectively, but also strengthen bonds and support long-term hair health, with options for fine, blonde, or buildup-prone hair.

This reparative shampoo is a staple for dry, damaged, or colour-treated hair. It gently cleanses while actively repairing bonds, leaving hair stronger, shinier, and healthier with every wash.

The fine bonding shampoo is a lighter take on the original, and this formula is specifically designed for fine or flat hair. It maintains strength and shine while boosting volume and lift.

A rich purple shampoo that tones brassiness in blonde, silver, or grey hair. Unlike many toning shampoos, it doesn’t dry out the hair but instead strengthens the hair while it tones.

This clarifying formula removes buildup, excess oils, and pollutants that can dull your hair. Ideal for weekly or biweekly use to reset your hair and enhance the performance of other Olaplex products.

An ultra-light dry shampoo that refreshes hair between washes without leaving a residue. It also offers scalp-balancing benefits and adds natural volume.

Conditioning is about more than just softness. These formulas deliver intense hydration while actively repairing bonds, improving elasticity, and protecting the hair from daily stress. Whether your hair is thick, fine, blonde, or frequently styled, there’s an Olaplex conditioner to support it.

This rich, daily-use conditioner deeply hydrates and restores elasticity. It is ideal for medium to thick hair types, and it is effective in smoothing, strengthening, and protecting against further damage.

For those with fine or easily weighed-down hair, this version of No. 5 delivers the same bond-building benefits in a lightweight formula.

This conditioner pairs with No. 4P Shampoo to lock in tone and add hydration. It helps maintain cool blonde tones while softening and strengthening.

Being a recent launch, this multitasking leave-in conditioner provides daily moisture, detangling, UV protection, and frizz control. It is great for all hair types and excellent under heat styling.

Styling products are often overlooked in terms of hair health, but Olaplex integrates protection and repair into every formula. These stylers reduce frizz, add volume, define curls, and improve manageability whilst reinforcing bond integrity and shielding against heat damage.

With a frizz-fighting formula, No. 6 delivers 72 hours of smoothness, shine, and hydration. It also provides heat protection and is perfect for use before blow-drying or air-drying.

Designed for curly, wavy, or textured hair, this gel defines without crunch or stiffness. It repairs and strengthens bonds during styling.

This fine mist adds instant body and lift to limp hair while protecting against heat. It is especially great for anyone who wants a fuller blowout that lasts.

The finishing step in your routine should do more than just make your hair look good. These targeted serums and treatments provide long-lasting hydration, antioxidant protection, and shine, while continuing to support hair strength and resilience.

A lightweight finishing oil that boosts shine, tames frizz, and protects against UV and heat up to 232°C. A little goes a long way and it’s perfect for all hair textures.

By targeting damage at the molecular level, its products go beyond surface-level fixes to deliver long-term strength, shine, and resilience. With the right combination of treatments, cleansers, conditioners, and finishers, you can build a personalised Olaplex routine that genuinely transforms your hair from the inside out.
