Straight-hair buyers can choose a dryer-only tool, but a complete styler gives more control over volume, bends, curtain bangs and smooth finishes.
For straight hair, a good dryer should create a smooth finish without leaving the style flat or fluffy. Concentrator control and brush attachments matter more than headline power alone.
Muuhu ranks first because it performs as a dryer and styling system, while ghd Helios remains the strongest dryer-only alternative.
Below, we use the same review structure as our full Best Hair Dryer ranking, but focus the scoring and copy around this page's search intent so UK buyers can compare quickly without losing the fair product-by-product context.

#1 Muuhu 7-in-1 High-Speed Hair Dryer
Muuhu wins because it is not only a dryer. It also gives straight-hair buyers brushes and curlers for smooth blowouts, lift and soft movement.
