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.

Biotin & Collagen Extra Strength Volumizing Shampoo for Fine Hair

Many reviewers say the shampoo cleans and lathers acceptably but note the claimed volumizing or strengthening effect is mild to unnoticeable after weeks of consistent use.

A minority of reviewers report increased shedding or oily-feeling roots the day after use, describing the effect as the opposite of the product's stated benefits.

A recurring complaint from reviewers with fine, color-treated or bleached hair is that the shampoo leaves hair feeling dry, stripped or straw-like with repeated use, sometimes requiring a switch back to a prior shampoo.

Reviewers repeatedly single out the scent as the strongest positive, describing it as fresh, sweet and long-lasting even before any effect on hair strength is noticed.

Blonde Enhance + Purple Toning Shampoo

Reviewers with blonde, highlighted or bleached hair repeatedly report it neutralizes brassy or yellow tones and brightens color within one to a few washes.

Several reviewers report noticeable hair shedding or hair loss during use and say they stopped buying it after hearing news reports linking OGX products to hair loss claims.

A recurring complaint is that regular use dries hair out, with several reviewers recommending limiting it to once or twice a week and always following with a conditioner or mask.

A large group of reviewers praise the scent as pleasant and not overpowering, distinguishing it favorably from other purple shampoos they have tried.

Reviewers who normally buy salon-brand purple shampoos (Pureology, Fanola, Kristin Ess) describe this as a comparable but slightly less pigmented, budget alternative.

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.

$0.77/oz vs $0.82/oz — within about the same cost per ounce.

$0.00/oz median $1.47/oz $17.29/oz $0.77/oz Biotin & Collagen Extra St $0.82/oz Blonde Enhance + Purple To

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.
