Olaplex No. 5 Leave-In Moisturize & Mend Leave-In Conditioner 3.3 oz
Overview
Olaplex No. 5 Leave-In Moisturize & Mend Conditioner (3.3 oz) is a concentrated leave-in treatment designed to strengthen, hydrate, and smooth hair between washes. It uses Olaplex’s patented bond-building chemistry (Bis-Aminopropyl Diglycol Dimaleate) to help reduce breakage and improve manageability while providing lightweight moisture to mid-lengths and ends. Packaged in a travel-friendly 3.3 fl oz tube, this formula is suited to people with color-treated, chemically processed, heat-styled, or frizz-prone hair who need daily repair and protection without heavy residue. It’s best used sparingly on very fine hair to avoid weighing strands down, but for most users it doubles as a detangler, heat protectant booster, and overnight leave-in to speed visual improvement in texture and strength.
Key Features
- Size: 3.3 fl oz (approximately 98 mL) — travel- and trial-friendly packaging.

Pros & Cons
Pros
- Contains Olaplex’s patented bond-building ingredient to help reduce breakage and mend weakened bonds.
- Lightweight, non-greasy leave-in formula that hydrates mid-lengths and ends without heavy buildup.
- Improves detangling and manages frizz, making styling easier and extending the life of color and chemical services.
- Travel-friendly 3.3 fl oz size convenient for trials, gym bags, and carrying on flights.
- Versatile: can be used daily, before heat styling, or as part of a post-wash maintenance routine.
Cons
- Premium-priced for the small 3.3 fl oz size, so cost per ounce is higher than many leave-ins.
- Small tube will wear out quickly for long or thick hair unless used sparingly.
- May weigh down very fine or oily scalps if over-applied to roots.
- Not a substitute for in-salon professional bond reconstruction for extremely compromised hair.
Recommendations
- Color-treated or bleached hair that needs ongoing bond maintenance and protection between salon visits.
- Heat-styled hair: for people who regularly use blow dryers, straighteners, or curling irons and want added protection.
- Travelers or first-time users who want a smaller, portable size to trial the Olaplex leave-in system.
- Individuals with frizz, dry ends, or tangling issues who want a lightweight detangling and smoothing leave-in.
