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.

Both praised for hold. Aussie Mega Hair Spray draws complaints about hold and residue or cast.

Mega Hair Spray

Older/curated reviews (predating the reformulation complaints) describe a pleasant, light scent and a hold that doesn't feel crunchy or stiff

curated 'what others are saying' reviewers

New formula leaves a white, flaky residue, especially noticeable on dark hair

a long-time user with dark hair

A formula change is widely reported to have ruined the product -- reviewers who used it for years say the new version is sticky, stiff, and no longer 'flexible'

long-time repeat buyers (some citing 10-15+ years of use)

Reformulation also changed the hold: reviewers say the spray now feels wet and provides little to no lasting hold

decades-long repeat buyers

Miracle Curls 2nd Day Curl Activator

Tames frizz and locks in shine on wavy/curly hair

CVS reviewer (Julie)

Reactivates curl pattern on hair that's straight until wet, adds volume and hold without oiliness

Walmart reviewer (Virginia/Shela)

Cuts styling time by refreshing curls without a full rewash, adds moisture

Walmart reviewer (M)

Revives second-day curl pattern and adds shine without a rewash

CVS reviewer (Ljc12) on curly hair

Fragrance is strong right after spraying but settles down once dry

Walmart reviewer (Shela)

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.
  • 7 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.
