Olaplex invented a category. When it launched in 2014 with a single patented molecule — Bis-Aminopropyl Diglycol Dimaleate — it gave the professional hair world its first true bond-building technology. By reconnecting broken disulfide bonds within the hair cortex, Olaplex repairs damage at a structural level rather than coating it over.
The numbered system makes Olaplex uniquely approachable: each step has a number, a clear purpose, and works synergistically with the others. Numbers 1 and 2 are professional salon treatments used during color services. Numbers 3 through 9 extend the bond-building benefit into the home routine — from the pre-shampoo Hair Perfector to the silky Bonding Oil and the ultra-nourishing Bond Intense Moisture Mask.
ProHair.ca is your authorized Canadian source for the complete Olaplex lineup. We carry both the professional salon steps and the full at-home maintenance range, so clients can keep their bond-building results going between appointments.

Frequently Asked Questions
What makes Olaplex different from other bond repair treatments?
Olaplex holds the patent on Bis-Aminopropyl Diglycol Dimaleate (Bis-MADJ), the single active molecule that actually reconnects broken disulfide bonds within the hair's cortex. Other bond-building products mimic this approach but use different molecules. The original patented ingredient is exclusive to Olaplex.
Do I need to use all the Olaplex numbers?
No — you can start with one or two products and build from there. The most popular entry point is No. 3 Hair Perfector used weekly before shampooing. Adding the No. 4 shampoo and No. 5 conditioner extends the benefit through every wash.
Can I use Olaplex with color-treated hair?
Yes — Olaplex is specifically designed to be used with and after color services. Nos. 1 and 2 are added to color and bleach formulas in the salon to protect bonds during processing. The at-home range maintains those results between appointments.
How often should I use Olaplex No. 3?
For damaged hair, use No. 3 once a week. For maintenance on healthy color-treated hair, every 2–3 weeks is sufficient. Apply to damp hair, leave on for at least 10 minutes (or overnight for deep repair), then shampoo out.
Is Olaplex worth the price?
Olaplex products typically range from $38–$55 CAD at ProHair.ca. Given that they replace multiple products and deliver structural repair rather than surface coating, most clients find the value strong. The No. 3 alone can replace separate masks, treatments, and conditioners.
Can Olaplex reverse severe bleach damage?
Olaplex significantly improves the condition of bleach-damaged hair and can restore elasticity and reduce breakage. However, it cannot restore hair that has reached the point of "hygral fatigue" or extreme over-processing. Prevention — using Nos. 1 and 2 during bleaching — is always more effective than repair after the fact.
Is Olaplex safe for pregnancy?
Olaplex products are free from sulfates, parabens, and phthalates. While there are no specific clinical trials for pregnancy use, many clients use the at-home range safely. We recommend consulting your healthcare provider for the in-salon treatments.
