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.

American Crew Defining Paste draws complaints about frizz.

Boost Powder

Reviewers with thinning or fine hair say the powder provides lasting texture and volume all day.

Several reviewers value that the product is effective on hot, humid days without adding oiliness.

Multiple reviewers say a jar lasts a long time because only a small amount is needed per use.

Defining Paste

Consistently works on thick, hard-to-style hair where other pastes have failed.

5-star Ulta reviewer describing years of use on a partner's thick hair

Builds texture and hold without leaving visible product buildup, for a natural look.

4-star Ulta reviewer

A little goes a long way — one fingertip amount lasts all day and the tub lasts a very long time despite the price.

5-star Ulta reviewer weighing cost against longevity

Needed an unusually large amount to work and it made hair look dirty; didn't control frizz as advertised.

1-star Ulta reviewer

Scent is strong and lingers through the day; product needs to be warmed between palms first or it leaves white clumps.

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.
