Overview
Olaplex No.5 Bond Maintenance Strengthening Conditioner is a color-safe, sulfate-free rinse-out conditioner formulated for medium-to-coarse hair. It's designed to follow Olaplex's No.4 shampoo as part of a bond-repair system.
The strength and breakage figures on the label (2x stronger, 60% less breakage, and similar) are measured when No.5 is used together with No.4 Bond Maintenance Shampoo, not as a standalone claim. It's also pitched specifically at medium-to-coarse hair, with Olaplex selling a separate No.4Fine line for finer strands.
- Formulated for medium-to-coarse hair
- Panthenol and glycerin moisture complex
- Vegan, dermatologist tested, color-safe
- Concentrated formula at about 5 mL per use
Who it's for
Fits people with medium-to-coarse, color-treated or chemically processed hair who already use or are willing to add the matching No.4 shampoo. Fine-haired buyers are better served by Olaplex's Fine line instead.
Pros and cons
- Concentrated, so a little covers many applications
- Vegan and dermatologist tested
- Color-safe for chemically treated hair
- Full claimed results depend on pairing with No.4 shampoo
- Formulated for medium-to-coarse hair, not fine strands
- Salon positioning implies a premium price point
Performance notes
Applied to mid-lengths and ends after shampooing with No.4, left on 1 to 3 minutes, then rinsed. Panthenol and glycerin draw moisture into the hair to support hydration and help prevent breakage, and the formula is concentrated enough that a 5 mL application stretches each bottle size well.
