John Frieda ULTRAfiller+ Thickening Spray is a leave-in styling product for fine or thin hair, used on towel-dried hair and blow-dried to create a fuller-looking style. The available evidence does not establish typical results or provide independently verified review photos of this exact spray, so the brand’s claims should not be mistaken for a product test.
What the spray is—and how to use it
John Frieda describes ULTRAfiller+ Thickening Spray as a styling spray intended to make fine, thin hair look fuller. Its US product page directs users to apply it throughout towel-dried hair, fully cover the roots and under sections, comb from root to tip, then blow-dry until completely dry. The brand’s wording is: “For maximum fullness, style hair using a blow-dryer until completely dry.”
- Spray throughout towel-dried hair, including the root area and under sections.
- Comb from roots to tips to distribute the product.
- Blow-dry until the hair is completely dry.
The Canadian product page lists the spray in a 150 ml size.
What John Frieda claims—and what the evidence shows
John Frieda advertises “200% thicker, fuller” hair when its ULTRAfiller+ Shampoo, Conditioner and Spray are used together, compared with basic or conventional shampoo. That is a manufacturer claim about the three-product routine, not evidence that the spray alone produces that result. The product pages do not establish how typical users will fare.

- HAIR THICKENING SPRAY - This thickening spray visibly plumps your hair so that it’s thicker, fuller and ready to style in just 1 use
- PLUMPS - This volumizing spray is infused with biotin and hyaluronic acid–it visibly plumps overall thickness by 200% (with ULTRAfiller range vs basic shampoo)
- HEAT PROTECTION - Thin or fine hair can be fragile, so this volumizing spray gives you heat protection while you’re styling
- LIGHTWEIGHT HAIR SPRAY - This thickening spray feels light, yet gives you long-lasting hold that makes your hair look voluminous without feeling heavy, sticky or crunchy
- MORE THAN HAIR SPRAY - Try the whole ULTRAfiller+ line–all three products (thickening spray, shampoo, conditioner) give the best results
The Canadian page also claims heat protection during styling up to 220°C/430°F and says the formula helps defend against hair loss from breakage. These are manufacturer statements; independent verification was not established. The page does not provide grounds for treating the heat-protection figure as a guarantee for every styling tool or routine.
Formula and ingredient considerations
John Frieda describes the formula as infused with biotin and hyaluronic acid. Its Canadian ingredient listing includes water, alcohol denat., polyquaternium-16 and polyquaternium-68, panthenol, hydrolyzed rice protein, glycerin, caffeine, hyaluronic acid, tocopheryl acetate, biotin, fragrance, preservatives and fragrance components. The listing does not establish ingredient concentrations or effects, and ingredients alone cannot predict how the spray will feel or perform on an individual’s hair.
Rank #2

John Frieda notes that formulas can change and advises checking the packaging for the current ingredient list. If a particular ingredient matters to you, compare the package in hand with the online listing before use.
Are there review photos or independent results?
The product-page material and search evidence available here do not establish representative real-world results or independently verified photos of the exact ULTRAfiller+ Thickening Spray. Promotional before-and-after imagery, if shown on a product page, is not an independent test. A related fine-hair forum discussion asks about John Frieda Pro Filler, but that is a different, category-adjacent product discussion—not a review of this spray.

That distinction matters because styling results depend on the amount applied, hair length and texture, where it is applied, and the blow-drying routine. Without a documented test using this specific spray, claims about volume, residue, stiffness, scent, or how long a style lasts should not be presented as observed results.

It may be worth considering if you have fine or thin hair and want a leave-in product designed to be distributed through damp hair and activated as part of blow-drying. The evidence supports describing its intended use and manufacturer claims, but not promising a particular change in fullness. Readers who need a proven result should look for an independent review that identifies the tester’s hair type, application amount, styling method and outcome.
