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.
ProGrowth + Peptide Hair Strengthening Scalp Serum
Many reviewers say results were inconclusive after weeks of consistent daily use, with no visible change in hair growth, thickness or density.
A recurring complaint targets the twist/push applicator, which many reviewers find hard to unlock, prone to leaking, or breaking after a short time.
Some reviewers report the serum left hair or scalp feeling greasy, itchy or irritated, and a few describe a small bottle that runs out quickly relative to the price.
Reviewers repeatedly describe the serum as lightweight, fast-absorbing and non-greasy, leaving little to no residue on the scalp.
The fragrance-free formula is appreciated by reviewers with scalp sensitivity, though a few wished it had some scent.
Clean Beauty Scalp Therapy Drops
A few reviewers report their dandruff got worse or the product made no noticeable difference after weeks of use.
Many reviewers with dry, flaky or itchy scalps say the drops relieve irritation without leaving hair oily or weighed down.
Several reviewers describe the dropper applicator as messy or hard to control, with liquid running out before it reaches the scalp.

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.

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.
- 10 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.
