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.
No.0.5 Scalp Longevity Treatment
The precision applicator tip is repeatedly praised as easy to use for parting hair and applying product directly to the scalp without mess.
general reviewersReviewers with dry, itchy, tight or menopause-related scalp issues report noticeably less dryness, tightness and itchiness with regular use.
reviewers with dry, itchy or aging scalps, including menopause-related scalp changesA large recurring complaint is that the product has a strong, unpleasant smell that reviewers compare to rancid cheese, yeast, or ammonia, unlike other Olaplex products.
reviewers across hair and scalp typesSeveral reviewers found the product made no noticeable difference to their scalp or hair volume, calling it expensive for the small tube size relative to results.

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.
- 8 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.
