What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, Olaplex No.3 Plus is the most-reviewed bond treatment in the pool by a wide margin — roughly 138,000 Amazon ratings at a 4.6 average — and allure.com's coverage of the reformulated Plus version frames it as a faster, more nourishing iteration of the original pre-shampoo treatment. Refinery29 echoes the framing as a souped-up reformulation. For chemically damaged, bleached or heat-stressed hair, this remains the category's most-cited bond builder.
What reviewers liked
- Backed by verified-tier coverage at allure.com and high volume of positive verified-purchase reviews
- High-trust r/HaircareScience users report visible shine and reduced flyaways with consistent weekly use
- Faster 3-minute pre-shampoo application in the Plus reformulation
- One of the only widely available take-home products with patented bond-repair chemistry
Where it falls short
- High-trust subreddit threads document a real pattern of breakage and dryness complaints, especially on fine or already healthy hair
- Reviewers on r/newinbeauty report severe negative experiences even with verified retail purchases
- Expensive per ounce compared to moisture-focused masks with similar softness results
- Often requires layering with the rest of the Olaplex system to deliver advertised results, which compounds cost

The disagreement is real and worth surfacing. r/HaircareScience threads — a high-trust specialist source — include both users reporting visibly shinier, healthier hair after consistent weekly use AND a separate, well-documented body of complaints about breakage at the roots, dryness, and hair loss, particularly when the wider Olaplex system is layered on. Community moderators on that subreddit have noted that the line works well when used correctly on chemically damaged hair, and tends to backfire on hair that is healthy, fine, or already protein-sensitive.
The trust-weighted read: this is a legitimate bond-repair product backed by verified beauty press and an enormous user base, but it is not a universal mask. Reviewers consistently advise treating it as a targeted treatment for actual chemical damage rather than a general moisture booster.
