What Olaplex Is and Who It Is For
Olaplex is a professional-grade bond-repair line that many salon clients and at-home users reach for when hair has been bleached, coloured or heat-damaged. At Classique Nail Supply, we stock the core Olaplex range. Reported first-quarter 2026 results from Yahoo Finance coverage of Olaplex's first-quarter 2026 results show professional sales rising 12.3% to US$38.8 million, while retail sales fell 13.3% to US$33.4 million.
Olaplex suits people with chemically treated hair who want a structured routine. It is less of a fit for someone with healthy, untreated hair who wants a simple shampoo.
Olaplex for Damaged Hair: What the Products Claim
The No. 3 Hair Perfector is listed as reversing damage, strengthening hair and reducing future breakage.
The claims are specific, but the proof behind them is less clear. Olaplex's company page on hair health and product safety says its testing showed no sign of skin irritation or sensitization, though the full testing details are not public in the material we reviewed.
Olaplex Products Compared Side by Side
Most product pages list sizes and prices and stop there. The more useful question is which formula fits your hair type, how much damage you are actually treating, and what each application costs. The table below compares the four core products we stock on those terms.
| Product | Size | CAD Price | Best For | Approx. Cost Per Use |
|---|---|---|---|---|
| No. 3 Hair Perfector | 3.3oz | $41.00 | Severely damaged, bleached or chemically treated hair | About $6.80 per weekly treatment (roughly 6 applications per bottle) |
| No. 4 Bond Maintenance Shampoo | 8.5oz | $41.00 | Everyday cleansing between treatments | About $1.40 per wash (roughly 30 washes per bottle) |
| No. 5 Bond Maintenance Conditioner | 33.8oz | $127.00 | Daily conditioning and manageability | About $1.25 per use (roughly 100 uses per bottle) |
| No. 4P Blonde Enhancer Shampoo | 8.5oz | $41.00 | Brassy blonde or toned hair | About $1.40 per wash (roughly 30 washes per bottle) |
Which product for which hair type
- Chemically damaged or over-processed hair: No. 3 is the treatment most likely to matter. Use it consistently for several weeks before judging results, and avoid layering multiple bond-building products at once.
Trade-offs to know before you buy
- The No. 4P Blonde Enhancer is a toning shampoo.

Building an Olaplex Routine, Step by Step
A routine only works if the products fit together and you are not doubling up on the same job. Here is the order that makes sense, plus the compatibility questions people ask most.
OLAPLEX No. 3 Hair Perfector (3.3oz) →
The core order
- Treat first. In the shower before shampooing, apply No. 3 Hair Perfector from roots to ends until saturated. Leave it on for 3 to 10 minutes, then rinse well.
- Shampoo. Apply a coin-sized amount of No. 4 Bond Maintenance Shampoo (8.5oz) to wet hair, lather thoroughly, and rinse well.
- Condition. Apply No. 5 Bond Maintenance Conditioner (33.8oz) to mid-lengths and ends, leave it on for 1 to 3 minutes, and rinse well.
Compatibility and redundancy
- Leave-in products go last. Any leave-in treatment or styler goes on after conditioning, on damp hair, not before the treatment step.
How often to use each product
- No. 4 and No. 5: every wash day, or as often as you normally shampoo.
- No. 4P: as needed for brassiness. Listed for weekly or as-needed use.
A simple weekly schedule
- Two treatment days: No. 3, then No. 4, then No. 5.
- Two regular wash days: No. 4, then No. 5.
- One toning day (if blonde): No. 4P instead of No. 4, then No. 5.
- Remaining days: no wash, or a water rinse if you prefer.
How Often to Use Olaplex Without Overdoing It
Using the treatment too often on fine or already fragile hair can leave it feeling stiff or weighed down. Start with once a week, then adjust based on how your hair looks and feels.
Evidence, Criticism and Realistic Expectations
Olaplex's commercial story has also drawn attention. CNBC reporting on Olaplex's stock performance since its IPO describes a sharp fall in the share price since the public debut, and the company has been pursuing a turnaround. A business turnaround does not change how a product performs, but it is worth knowing when you read the marketing.
Choosing Your Olaplex Products at Classique Nail Supply
For damaged hair, the No. 3 Hair Perfector is the treatment step, followed by the No. 4 Bond Maintenance Shampoo and No. 5 Bond Maintenance Conditioner. If your hair is brassy from colour, the No. 4P Blonde Enhancer Toning Shampoo is a separate option.

Frequently Asked Questions
Will Olaplex help my hair?
Olaplex positions its products around reducing breakage and strengthening hair, and the No. 3 Hair Perfector is described as reversing damage and reducing future breakage. The listings do not provide independent test results, so results will vary with hair condition and how consistently you use the products. Treat it as a bond-maintenance step within your routine rather than a one-time fix for severely damaged hair.
Which Olaplex products should I use for damaged hair?
For damaged hair, the No. 3 Hair Perfector is the treatment step, applied in the shower before shampooing and left on for 3 to 10 minutes. It is meant to be followed by the No. 4 Bond Maintenance Shampoo and the No. 5 Bond Maintenance Conditioner. If your hair is also brassy from colour, the No. 4P Blonde Enhancer Toning Shampoo is a separate option that neutralizes brassiness while strengthening.
How often should you use Olaplex?
The No. 3 treatment is used as a pre-shampoo step, so frequency depends on your hair's condition and your schedule. The No. 4P toning shampoo is listed for weekly or as-needed use. Start with a conservative schedule and adjust based on how your hair feels.
Can Olaplex be used on all hair types?
The product listings describe benefits for hair generally, including reduced breakage, hydration and improved manageability, but they do not limit use to specific hair types. Check your own results over a few weeks before committing to a full routine.
