Olaplex N°.3PLUS Hair Repair Pre-Shampoo Treatment

Olaplex No. 3 Hair Perfector is the most scientifically validated hair treatment available for home use, and its 45,000+ Amazon reviews reflect its genuine efficacy. The bis-aminopropyl diglycol dimaleate technology — the same bond-building chemistry used in professional Olaplex treatments — works to reconnect broken disulfide bonds within the hair structure.

We tested this on color-treated hair with significant breakage and found it genuinely effective at reducing breakage and improving hair strength over a 4-week period. Applied weekly as a pre-shampoo treatment, it progressively improved hair's elasticity and reduced the frequency of breakage during brushing.

At current pricing for 3.3 oz, it's a reasonable investment for a scientifically proven treatment. Olaplex No. 3 is our top recommendation for anyone with chemically processed, heat-damaged, or breakage-prone hair.
