Olaplex No. 1 Bond Multiplier (100ml)

Olaplex No.1 Bond Multiplier is the concentrated first step of the Olaplex system, mixed straight into bleach, lightener or color to protect and rebuild hair bonds while the chemicals work. It is the product to ask for, or bring to your colorist, if you lighten your hair and want it to come out stronger rather than straw-like.

Quick Facts

• 100ml
• Professional bond-building additive
• Patented Bis-Aminopropyl Diglycol Dimaleate
• Used with No.2 Bond Perfector
• Vegan
• All hair types and textures

Why It Works in the UAE

Blonding and balayage are popular here, and hair that has been lightened then faces strong sun, heat styling and mineral-heavy tap water breaks easily. No.1 protects the hair at the moment it is most vulnerable, during the chemical service itself.

Key Benefits

• Rebuilds broken bonds during bleach, color and other chemical services
• Reduces breakage, so hair feels stronger after lightening
• Lowers porosity for softer, smoother-feeling hair
• Mixes into your usual formula without changing processing results

Key Ingredients

• Bis-Aminopropyl Diglycol Dimaleate: Olaplex's patented molecule that links broken disulfide bonds back together

Who It Is For

Best for: bleached, highlighted, balayaged or chemically straightened hair; colorists and experienced home colorers.

Not ideal for: everyday home care on its own. For a weekly at-home treatment, Olaplex No.3 Hair Perfector is the easier choice.

How to Use

Add No.1 to color or lightener using the included mixing chart, keeping your usual formula unchanged. After processing, apply No.2 Bond Perfector. As a standalone treatment, mix No.1 with water in a non-spraying applicator and apply to clean hair, then follow with No.2.
