The bottom line

The bottom line depends on your hair

Which of these two suits you is a question about your hair, not about them. The consultation answers it — and tells you what your routine needs around it.

What owners say

What people report

Recurring themes our researchers wrote in their own words from sourced reviews. We do not store or scrape star ratings, and we never balance one product’s themes against another’s by inventing them.

Olaplex No.0 Intensive Bond Building Hair Treatment draws complaints about volume and breakage.

N°.3PLUS Complete Repair Treatment

The quick 3-minute treatment is much more convenient than the original No.3, which had a 10-30 minute wait time that discouraged regular use

comparing to original Olaplex No.3 Hair Perfector

After just one use, hair lengths looked and felt "brand new" with noticeably better results than expected

Reviewer appreciated that no heat is required to activate the formula, unlike other bond treatments

No.0 Intensive Bond Building Hair Treatment

Reviewers who use No.0 as the first step before No.3 Hair Perfector report visibly shinier, softer and more elastic hair, especially on color-treated or bleached hair.

reviewers pairing No.0 with No.3 on colored or damaged hair

Many reviewers say the spray nozzle dispenses a hard, narrow stream rather than a fine mist, making it difficult to distribute evenly and wasteful of product.

long-time and first-time users across hair types

Some reviewers on thin or fine hair say the product weighs hair down or gives no volume, especially when paired with the No.8 mask.

reviewers with fine or thin hair

A recurring minority of reviewers report the product made their hair drier, more breakage-prone or straw-like, sometimes describing it as an allergic reaction on the scalp or face.

Price check

Cost per ounce, in context

Cost per ounce against every product of this type we have priced, each at the size it is most often sold in. Value labels are computed from that percentile and from how many products that do the same job cost less; they are comparisons, not judgements about a brand.

$9.61/oz vs $10.30/oz — within about the same cost per ounce.

$0.19/oz median $3.49/oz $24.50/oz $10.30/oz N°.3PLUS Complete Repair T $9.61/oz No.0 Intensive Bond Buildi

Every mark sits on one distribution because these are compared against the same set: 347 masks and treatments with a computable unit price.

How this page was made

  • This page is assembled from the same researched records the individual product pages render: identity, each ingredient list as printed, each brand's own claims, dated price observations, and review themes written in our researchers' own words. Nothing on it is written per comparison.
  • We do not rank these against each other. Which of them suits you depends on your hair, and that is what the consultation works out.
  • The formula similarity percentage is a stored, precomputed number: position-weighted overlap of the two ingredient lists blended with agreement on the attributes we derive. It measures how alike two formulas are, not how well either works.
  • The value band is a fixed label over two stored numbers: this product’s cost per ounce as a percentile of every product of this type we have priced, each at the size it is most often sold in, and how many products we score as doing the same job cost at least a quarter less per ounce.
  • The "Is this right for you?" panel reads only your own consultation answers, and it applies exactly the filters our recommendation engine applies. It is computed when you load the page and is never stored on it.
  • 9 sources were consulted across the products on this page.
  • Ingredient order tells you relative amount only above roughly 1%. Prices are observations on the dates shown and change without notice. We do not sell these products and take no placement fees.
  • This is cosmetic information, not medical advice, and nothing here diagnoses or treats a health condition.
