Bumble and bumble Thickening Blow-Dry Prep Spray - 8.5 oz draws complaints about weight and volume.

Thickening Blow-Dry Prep Spray - 8.5 oz

Works best used sparingly and applied before other styling products; gave hair volume and shine

reviewer macabeda (St. Louis), 5-star review

Boosts volume in fine hair and makes styling easier

reviewer Lyn (Oregon), 5-star review

High alcohol content dried out fine, color-treated hair and left an overpowering chemical odor that lingered on clothing

most-helpful negative review, 2-star

Left hair flat and staticky, felt like adding water rather than adding volume

reviewer Diana (Kansas), 1-star review

Adds volume and lift without weighing hair down; a little goes a long way, but the scent is a downside

reviewer Bbradley (Bloomington, IN), 4-star review

Thickening Full Form Soft Hair Mousse

A customer with fine, thinning hair says it works better than alternatives they have tried, though they wait for a promotion because of the price.

Ulta customer review by Jan

A fine, wavy-haired reviewer says even a very small amount left their roots too stiff to run fingers through.

Ulta customer review by LC

A detailed critical review from a very-fine-haired user says this Soft version makes their hair lie flatter than the earlier product they preferred, despite liking that predecessor's fuller, non-tacky texture.

Ulta most-helpful critical review

One user says the mousse performed as advertised but reports substantial shedding after two uses; this is an individual review report, not a verified causal effect.

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.
  • 3 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.
