If you've ever walked out of a salon after a colour or bleach treatment and your stylist mentioned "Olaplex," you're not alone. Olaplex has become one of the most talked-about names in professional hair care — and for good reason. It genuinely changed the game for anyone who colours, bleaches, or heat-styles their hair.
But what exactly is Olaplex? How does it work? And with so many numbered products (No.0 through No.9), which ones do you actually need? Let's break it all down.
The Science Behind Olaplex
To understand Olaplex, you need to understand what happens to your hair during chemical treatments. Your hair's strength comes from millions of disulfide bonds — molecular connections within the hair shaft that give it structure, elasticity, and resilience. Every time hair is bleached, coloured, permed, or exposed to excessive heat, some of these bonds break. The more bonds that break, the weaker, drier, and more damaged your hair becomes.
Traditional conditioners and masks work by coating the outside of the hair shaft, making it feel smoother temporarily. But they don't actually repair the internal damage. Olaplex is fundamentally different. Its patented active ingredient — Bis-Aminopropyl Diglycol Dimaleate — works at the molecular level to find broken disulfide bonds and relink them. It literally reconnects what chemical and heat damage has torn apart.
This isn't marketing hype. Olaplex was developed by two chemists, Dr. Eric Pressly and Dr. Craig Hawker, and its bond-multiplying technology was validated through rigorous scientific testing before it ever reached a salon. The result? Hair that's not just softer on the surface, but genuinely stronger and more resilient from the inside.
The Olaplex System: Every Product Explained
Olaplex uses a numbered system that can feel confusing at first, but it's actually quite logical. Here's what each product does and who needs it.
No.0 — Intensive Bond Building Treatment
No.0 is a primer that prepares and opens up the hair to maximise the effectiveness of No.3. You apply it before No.3 for a deeper, more intensive repair treatment. Think of it as the booster that makes No.3 work even harder.
Who needs it: Anyone with moderate to severe damage who wants the maximum repair from their at-home treatment.
No.3 — Hair Perfector
This is Olaplex's hero product and likely the one that put the brand on the map for consumers. No.3 is not a conditioner — it's a treatment that repairs bonds before you shampoo. You apply it to damp hair, leave it for at least 10 minutes (longer for more damage), then shampoo and condition as normal. Use it once a week for maintenance or more frequently if your hair is severely damaged.
Who needs it: Everyone. Seriously. Whether your hair is bleached, coloured, heat-styled, or just exposed to daily wear and tear, No.3 will strengthen it.
No.4 — Bond Maintenance Shampoo
A gentle, pH-balanced shampoo that continues Olaplex's bond-repair work while cleansing. It's sulfate-free and safe for coloured hair, and it helps maintain the results of your No.3 treatments between uses.
No.5 — Bond Maintenance Conditioner
The daily conditioner that repairs, hydrates, and detangles. It provides moisture and smoothness while continuing to work on those disulfide bonds. No.4 and No.5 work together as your everyday wash-and-condition step.
No.4P — Blonde Enhancer Toning Shampoo
A purple-tinted version of No.4 designed specifically for blonde, grey, and silver hair. It neutralises brassy, yellow tones while providing the same bond-repair benefits. Use it in place of No.4 whenever your blonde needs toning.
No.6 — Bond Smoother
A leave-in styling cream that eliminates frizz and flyaways for up to 72 hours. It also provides heat protection and speeds up blow-dry time. No.6 is especially popular in humid climates — making it perfect for Cyprus summers.
No.7 — Bonding Oil
A lightweight finishing oil that adds brilliant shine, tames frizz, and provides heat protection up to 232°C. It's incredibly versatile — use it on damp hair before styling, or on dry hair as a finishing touch for that healthy, glossy look.
No.8 — Bond Intense Moisture Mask
The most hydrating product in the Olaplex range. No.8 is a 4-in-1 mask that repairs bonds while adding intense moisture, smoothness, body, and shine. Apply after shampooing, leave for 10 minutes, and rinse. It's ideal for anyone whose hair is both damaged and dry.
No.9 — Bond Protector Nourishing Hair Serum
A lightweight, non-greasy serum that provides heat protection up to 232°C, UV protection, and anti-pollution defence. It seals the hair cuticle for a smooth, shiny finish. Think of No.9 as your daily shield against everything your hair faces.
Building Your Olaplex Routine
You don't need every single Olaplex product to see results. Here's how to build your routine based on your needs:
The Essentials (start here): No.3 (weekly treatment) + No.4 (shampoo) + No.5 (conditioner). This trio gives you the core Olaplex bond-repair experience.
Add Intensity: Include No.0 before your No.3 treatment for deeper repair, and No.8 mask once a week in place of No.5.
Add Styling: No.6 (leave-in smoother) for frizz control, No.7 (oil) for shine, or No.9 (serum) for heat and UV protection.
For Blondes: Swap No.4 for No.4P once a week to keep your colour cool and bright.
In-Salon vs. At-Home Olaplex
It's worth noting that Olaplex No.1 and No.2 are professional-only products used by stylists during chemical treatments. No.1 (Bond Multiplier) is mixed into bleach or colour to prevent bond breakage as it happens, while No.2 (Bond Perfector) is applied after the service to continue rebuilding bonds. If your stylist offers an Olaplex add-on during your colour appointment — take it. It makes a significant difference to how your hair handles the chemical process.
The at-home products (No.0 through No.9) are designed to maintain and extend the results of in-salon treatments, while providing ongoing bond repair for everyday damage.
Olaplex and K18: Better Together
| K18 | Olaplex | |
| Technology | Bioactive peptide (K18PEPTIDE™) | Bond-builder (bis-aminopropyl diglycol dimaleate) |
| What it repairs | Reconnects broken keratin chains in the cortex | Relinks broken disulfide (sulfur) bonds |
| Time | 4 minutes, leave-in | No.3: ~10 minutes, rinse out |
| Routine | One leave-in step | Numbered system (No.0–No.9) |
| Rinse? | No-rinse | Rinse out (No.3) |
| Best for | Fast, simple at-home repair | A complete bond-maintenance system |
| Shop in Cyprus | K18 at WOOP | Olaplex at WOOP |
Both rebuild damaged hair from the inside. K18 if you want one fast leave-in step; Olaplex if you want a full system to maintain bonds over time. We advise first: the best one is the one you'll actually use consistently.
Olaplex and K18 aren't rivals — they're complementary. Olaplex relinks broken disulfide bonds (the "rungs" of the hair's structure), while K18's biomimetic peptide rebuilds the polypeptide chains (the "poles"). Many professionals use both: Olaplex during and after chemical services, K18 as an at-home molecular top-up. If you're serious about repair, it's worth exploring both ranges.

Olaplex — Frequently Asked Questions
What does Olaplex actually do to your hair?
Olaplex works by reconnecting broken disulfide bonds in the hair's keratin structure. These bonds break during chemical processes like bleaching, colouring, and heat styling. Olaplex's active ingredient, Bis-Aminopropyl Diglycol Dimaleate, seeks out and links broken bonds back together — restoring strength, elasticity, and integrity from the inside out rather than just coating the surface.
Is Olaplex a conditioner or a treatment?
Neither exclusively — Olaplex is a bond-building system spanning multiple product types. No.3 is a pre-shampoo treatment, No.4 and No.5 are shampoo and conditioner, No.8 is a mask, and No.6 and No.7 are leave-in stylers. Each product contains the same bond-building active, so the system works cumulatively across your entire routine.
How often should I use Olaplex No.3?
For damaged or chemically treated hair, use No.3 Hair Perfector once a week before shampooing. Apply to damp hair, leave for a minimum of 10 minutes (longer for more damaged hair), then shampoo and condition as normal. For maintenance on healthier hair, once every two weeks is sufficient.
Can I use Olaplex if I don't colour my hair?
Yes — Olaplex is effective on any hair with bond damage, regardless of the cause. Heat styling, UV exposure, hard water, and mechanical stress (brushing, tying) all break hair bonds over time. Olaplex repairs this damage whether or not your hair has been chemically treated.
Is Olaplex safe for colour-treated hair?
Yes — Olaplex was originally developed for use during the bleaching process to prevent colour damage. It is fully compatible with all colour treatments and is used in salons worldwide as a colour service add-on. The at-home range (No.3 through No.9) is safe for daily use on colour-treated hair.
What is the difference between Olaplex No.3 and No.8?
No.3 is a targeted bond repair treatment used before shampooing — its primary function is structural repair. No.8 is a Bond Intense Moisture Mask used after shampooing — it combines bond-building with deep hydration and shine. Use No.3 for repair, No.8 for moisture and softness. They can be alternated or used together in the same routine.
