• Improves strength from inside out

Nº.4 Bond Maintenance Shampoo

If you loved Olaplex Nº.3, you need to incorporate Nº.4 Bond Maintenance Shampoo into your daily rotation.

It is the first step in the maintenance phase of Olaplex's system, designed to keep newly repaired bonds in place.

This shampoo lathers well but is surprisingly gentle, making it suitable for frequent washing. Many users find that their hair feels stronger after switching to this product exclusively.

Buyer’s Guide

Bond-Building Technology

To understand why Olaplex products work, you must understand bond-building technology. Most hair products work by coating the outside of the hair shaft (cuticle) with oils and proteins. Olaplex takes a different approach. Its proprietary ingredient, Bis-AMP (Bis-Aminopropyl Diglycol Dimaleate), is a small molecule that penetrates deep inside the hair fiber to find and reconnect broken disulfide bonds. These bonds are responsible for the hair's strength and shape. By repairing them from the inside out, Olaplex not only repairs damage but also helps prevent future damage.

Application Routine & Timing

The effectiveness of Olaplex products relies on consistent and correct application. For the most impactful results, use Nº.3 once a week (or twice weekly if your hair is very damaged) as a pre-shampoo treatment. Apply it to damp hair, leave it on for at least 10 minutes (or overnight for a deep treatment), then shampoo and condition. For daily maintenance, use Nº.4 Shampoo and Nº.5 Conditioner as a standard washing routine. No.6 can be used daily on damp or dry hair for styling and protection, while Nº.7 should be used as a finishing step after styling to lock in moisture and shine.

Hair Type Compatibility

Olaplex products are generally suitable for all hair types, from fine to coarse. However, the routine varies by type. If you have fine or thin hair, you may want to use Nº.4 and Nº.5 sparingly to avoid weighing hair down, and focus more on Nº.6 and Nº.7 for styling. If you have thick, coarse, or chemically treated hair, you can benefit heavily from the intense moisture of Nº.8 and 4-in-1 Mask. Curly-haired individuals often find Nº.6 and Nº.7 indispensable for frizz control and definition.

Repair vs. Maintenance Products

It is crucial to distinguish between repair products and maintenance products. Products like Nº.3, Nº.8, and the 4-in-1 Mask are repair-focused; they actively work to rebuild broken bonds and treat severe damage. Products like Nº.4 Shampoo, Nº.5 Conditioner, Nº.6, Nº.7, and Nº.9 are maintenance-focused; they keep the hair in good condition, protect against new damage, and maintain the repairs already made. A healthy routine requires both: repair for damage control and maintenance for daily protection.

Product Type Selection

Selecting the right type of product depends on your immediate needs. If you have a bad hair day or just had a chemical service, you need a Treatment/Mask (Nº.8 or 4-in-1). If you are looking to improve your daily wash routine, you need a Shampoo and Conditioner (Nº.4 and Nº.5). If you need to smooth hair or style it, a Leave-in Treatment (Nº.6) or Serum (Nº.7 or Nº.9) is best. Understanding these categories helps you avoid overloading your hair with too many products at once.

Budget Considerations

Olaplex products are generally considered an investment compared to mass-market drugstore brands. Nº.3 is the most affordable entry point ($34–$68). The Shampoo and Conditioner system (Nº.4 and Nº.5) and the Bond Smoother (Nº.6) are mid-range investments. The Bonding Oil (Nº.7) sits at a slightly higher price point. While the cost is higher, the effectiveness of the bond-building technology means you use less product than traditional conditioners, which can justify the price for many users seeking long-term hair health.

FAQs

How often should I use Olaplex Nº.3?
You should use Olaplex Nº.3 at least once a week. If your hair is severely damaged from bleaching or heat, using it two or three times a week will yield faster and more noticeable results.

What is the difference between Olaplex Nº.6 and Nº.7?
The primary difference lies in their function. Olaplex Nº.6 is a leave-in treatment designed for styling, smoothing frizz, and providing heat protection. Olaplex Nº.7 is a finishing oil that adds shine, seals in moisture, and protects against UV damage and heat styling. You can use both together for maximum effect.

Can I use Olaplex daily or weekly?
You can use Olaplex products daily as part of your routine, particularly Nº.4, Nº.5, Nº.6, and Nº.9. However, the intensive repair products like Nº.3 and Nº.8 are best used weekly or bi-weekly to prevent over-drying or weighing down the hair.

What is the difference between Olaplex shampoo and conditioner?
Olaplex Nº.4 Shampoo is formulated to cleanse the scalp and strands while actively repairing broken bonds. Nº.5 Conditioner hydrates the hair, seals the cuticle, and helps to restore strength and elasticity. They are designed to be used together for a complete bond-building wash.

Does Olaplex work on bleached hair?
Yes, Olaplex is specifically designed to repair hair that has been chemically treated, including bleached hair. The bleach process breaks the disulfide bonds, and Olaplex works to reconnect them, restoring the hair's structure.

How long should Olaplex stay on hair?
For Nº.3, you should leave it on for a minimum of 10 minutes. For best results, many users leave it on for 30 minutes to an hour or overnight. Leave-in products like Nº.6 and Nº.9 can be left on indefinitely, but Nº.8 should be rinsed out after 10 minutes.

Is Olaplex a leave-in conditioner?
Not exactly. Olaplex products vary by function. Nº.6 and Nº.9 act as leave-in treatments. Nº.7 is a leave-in oil. However, Olaplex also has traditional leave-in conditioners (like the Nº.5 Leave-In Moisturize & Mend) that function as standard conditioners but offer repair benefits.

Can I layer Olaplex Nº.7 over other products?
Yes, Nº.7 is designed to be a finishing product. It can be layered over styling creams, waxes, or leave-ins. It acts as a sealant to lock in moisture and protect against heat, so it is best applied at the very end of your styling routine after your hair is fully dry.

Our Top Pick

After reviewing the extensive range of Olaplex products available in 2026, our top pick for anyone starting their hair repair journey is Olaplex Nº.3 Hair Perfector.

While the Nº.4 and Nº.5 system is essential for maintenance, Nº.3 is the catalyst for change. It is the only product that actively targets and repairs broken bonds at the molecular level. It provides the foundational strength that allows all other products in your routine to work more effectively. For the best results, we recommend pairing Nº.3 with the daily Nº.4 Shampoo and Nº.5 Conditioner to maintain your newly repaired hair.
