Which? finds top hair dryers across budget ranges

Hair dryers divide consumers between budget buys and premium models. Which? Experts for You magazine tested 17 hair dryers for power, speed, and how well they leave hair bouncy and smooth, and highlighted a top three you should consider before buying.

Prices in the test ranged from about £26 for the cheapest to about £400 for the most expensive. The most expensive item tested was the Dyson Supersonic Nural at £400, while the cheapest was Tresemmé Smooth & Shine at £26.

The study used a mix of objective measurements and subjective judgments to compare performance. Testers weighed each model, measured cable lengths and tracked energy use. They deployed a decibel meter to gauge noise levels and an anemometer to measure wind speed. For the subjective portion, a ten-person panel with varying hair types used the 17 dryers and graded how effectively each dried and styled hair. The goal was to separate marketing claims from real-world results by combining data with user experience.

Which? notes that the organization has been testing products since 1957 and, unlike some outlets, buys the items before testing. That approach is meant to minimize bias from freebies and ensure independent results. See the full range of expert-recommended models at which.co.uk/hair-dryers.

BEST HIGH-END: Dyson Supersonic

Temperature settings: Three Speed settings: Three Weight: 490 g Cable: 256 cm

What works? Testers described the Dyson as easy to control, capable of drying hair quickly, lightweight, and strong for styling. It was among the quietest models and came with five head attachments to suit different hair types. The energy efficiency was also noted as a plus.

What’s the catch? The price tag is steep, with the Dyson not offering the lowest-cost option in the lineup.

BEST MID-RANGE: GHD Helios Professional

Temperature settings: Three Speed settings: Two Weight: 590 g Cable: 286 cm

What works? The GHD Helios was the best-rated option for curly and Afro hair, largely due to its concentrator nozzle that helps deliver ultra-smooth blow-dries. It also stood out for being relatively quiet despite its power.

What’s the catch? It’s heavier than many rivals, which some users may notice during extended styling sessions.

BEST BUDGET: Mark Hill Style Addict Perfect Blow Dry Kit

Temperature settings: Three Speed settings: Two Cable: 290 cm

What works? The Mark Hill model was easy to use and lightweight, drying hair effectively while offering good energy efficiency. It also includes clips, rollers, and a concentrator nozzle, which adds value at a low price.

What’s the catch? The airflow isn’t as strong as the Dyson or GHD products, and some users did not feel it was ideal for more advanced styling.

The article notes that even with familiar marketing terms such as ionic, ceramic, or tourmaline technologies, the real test is performance and user experience. While premium models offer strong control and quieter operation, mid-range options often deliver a strong balance of speed, weight, and value for money.
