Shoppers seeking a solution for fine, damaged, or ageing hair have been rushing to Boots after the retailer slashed the price of a highly-rated thickening spray. The John Frieda PROfiller+ Thickening Spray 150ml, which promises visible results after a single application, has been reduced from £9.25 to just £6.17.
What Makes This Thickening Spray So Popular?
The product has garnered an impressive 4.1-star rating from over 120 Boots customers, with many claiming it outperforms far more expensive salon alternatives. According to the brand, when used as part of a three-step system with its matching shampoo and conditioner, the spray can thicken hair overall by an impressive 200%. It also offers the added benefit of heat protection during styling.
One enthusiastic reviewer wrote: "Wow, this product by John Frieda is the best thickening spray I have ever used and trust me I have purchased nearly a tractor full of hair products." They praised its non-sticky feel and ability to add definition and height to fine, flat hair.
Another customer, accustomed to high-end products, was shocked by its efficacy: "After using highly priced salon products for years, I was shocked to see how well this product worked on my fine hair, especially as it was a fraction of the price."
The Full Range on Offer at Boots
The discount is not limited to the spray alone. Boots has also reduced the entire PROfiller+ range. Both the matching Thickening Shampoo and Thickening Conditioner are now priced at £6.17 each, down from £9.25. This makes it an opportune moment to try the complete regimen recommended for the maximum 200% thickening effect.
The spray is formulated with biotin for strength and hyaluronic acid for hydration. Boots states it is a lightweight, flexible-hold spray designed to plump fine hair without leaving any dulling residues.
How It Compares to Other Volumising Products
The Boots offer presents significant savings compared to similar products on the market. For instance, the WOW Raise the Root Volumising Spray costs £15.05 on Amazon, even with a 30% discount applied. Meanwhile, Superdrug sells the Charles Worthington Thicker and Fuller Densifying Mousse for £9.99, or £6.66 for members.
While feedback is overwhelmingly positive, one critical review noted the spray did not work for their fine, short hair, leaving it flat. This highlights that results can vary depending on individual hair type and style.
The product news was initially highlighted on December 7, 2025, and the current promotional price at Boots offers a cost-effective chance to test a product that has generated considerable buzz among beauty enthusiasts across the UK.
