Olaplex N°.5 Bond Maintenance Conditioner: Price Comparison
Olaplex N°5 Bond Maintenance Conditioner is a sulfate-free, color-safe conditioner built for medium-to-coarse hair — and it’s currently the best-selling prestige conditioner in the U.S. by dollar and unit sales. Unlike most drugstore “repair” conditioners, the formula skips protein entirely, leaning on bond-building chemistry plus panthenol and glycerin instead. That’s the detail most price-comparison pages miss, and it’s the one that actually explains why this conditioner behaves differently on damaged or color-treated hair. Below, we track what it costs right now across retailers so you can see where it’s genuinely the best deal — not just the first listing that shows up.

- Sulfate-free and color-safe
- Protein-free formula
- Works across straight, wavy, curly, and coily textures
- Dermatologist-tested and vegan
- Clinically shown to reduce split ends and frizz
- Formulated for medium-to-coarse hair — fine hair should use N°5FINE instead
- Best results depend on pairing with N°4 shampoo, which adds to total system cost
- Highly concentrated, so a full bottle lasts longer than it looks but the upfront price reads high
Quick Glossary
- Bond-building
A conditioning approach that targets the hair’s internal disulfide bonds rather than coating the surface with protein.
- Protein-free
Contains no protein additives — relevant for hair types that become brittle or stiff from protein overload.
- Color-safe
Formulated not to strip or fade chemically treated or color-processed hair.
OLAPLEX N°.5 Bond Strengthening Conditioner
Use N°.5 after N°.4 Bond Maintenance Shampoo and leave it on for 1–3 minutes — Olaplex’s clinical testing for frizz and split-end reduction is based on this two-step routine, not the conditioner alone.
Is Olaplex N°.5 safe for color-treated hair?
Yes. It’s formulated to be color-safe and sulfate-free, so it won’t strip or fade color-treated hair with regular use.
Does Olaplex N°.5 contain protein?
No — it’s a protein-free bond conditioner, which matters if your hair reacts poorly to protein-heavy treatments, a common cause of brittleness in fine or high-porosity hair.
What's the difference between N°.5 and N°.5FINE?
N°.5 is the concentrated formula for medium-to-coarse hair; N°.5FINE is a lighter, volumizing version made for fine hair. Using the wrong one is one of the most common complaints in reviews.
Do I need Olaplex N°.4 shampoo to use N°.5?
No. It works as a standalone conditioner, but Olaplex’s clinical results are based on using N°.4 and N°.5 together as a system.
How often should I use Olaplex N°.5?
It’s gentle enough for every wash. Apply after shampooing, leave on for 1–3 minutes, then rinse.
Is Olaplex N°.5 vegan and cruelty-free?
Yes, the formula is vegan and dermatologist-tested.
What size bottle should I buy?
Smaller sizes (250mL) suit occasional use or first-time buyers; the liter and jumbo sizes lower the cost per application significantly if you use it every wash.
Will Olaplex N°.5 weigh down fine hair?
It’s designed for medium-to-coarse textures and can feel heavy on fine strands — for fine hair, N°.5FINE is the better match.
