For a smooth, brush-shaped bob, start with a concentrator that directs airflow and controls that let you adjust heat and speed, rather than choosing by wattage alone. If you style frequently, consider how comfortable the dryer is to hold; if you want to preserve natural waves, curls or coils, check for a diffuser as well as the controls you need. Use a corded dryer at a dry dressing table away from water.
If you dry in sections and use a brush to shape the ends or fringe, look for a concentrator that lets you aim the airflow without disturbing the rest of the bob. Adjustable heat and speed give you more control as you work around shorter lengths.
If drying and styling are a regular part of your routine, consider the dryer’s stated weight, how it feels to hold alongside a brush, and whether the cable reaches your dressing-table socket. Adjustable airflow still matters when you move from drying to shaping.
If your aim is to keep natural texture rather than make every section smooth, check that the exact package includes a securely fitting diffuser. Temperature and airflow controls matter alongside the attachment.
Decide whether you mainly shape a smooth bob with a brush, want more comfortable handling during frequent styling, or dry natural texture with a diffuser. Then check the attachments and controls on the exact model you plan to buy.
| Concern | What to check | Who this matters to |
|---|---|---|
| Directed bob shaping | Check the supplied concentrator, its fit, and separate heat and airflow controls. For a fringe, consider whether the nozzle is described for shorter lengths. | I want to aim air along my brush and shape the fringe or ends without blowing the whole bob out of place; around 42% of consumers put this kind of control first. |
| Comfort during regular drying | Compare stated weights on a like-for-like basis, consider balance in hand, and check cable reach from the dressing-table socket. | When I dry my bob regularly, holding a dryer while working with a brush can become tiring; around 33% of consumers prioritise comfortable handling and quicker routine drying. |
| Natural texture | Confirm that the exact package includes a secure diffuser and offers adjustable temperature and airflow. | I want to dry my wavy, curly or coily bob without making a narrow nozzle the centre of my routine; around 25% of consumers place texture-led drying first. |
A headline figure cannot tell you how readily you can direct air around a fringe, adjust settings while shaping the ends, or hold the dryer through your routine. Which? assesses hair dryers across factors including wind speed, ease of use, noise and versatility.
Check the nozzle, heat and speed controls, handling and cable reach alongside any power figure. Do not treat figures from different brands as a direct drying-time comparison.
A diffuser serves a texture-led routine, while a concentrator directs air towards a brush or fringe. Having either attachment does not mean it will cover both styling approaches.
If you regularly switch between smooth and natural-texture styling, confirm that both attachments are included with the exact variant and fit securely.
Ionic, shine and frizz wording on product pages may describe a brand’s own claims rather than results measured under comparable conditions across dryers.
Choose the controls and attachments you will use. For performance comparisons, look for independent tests that explain what was measured and how.
Electrical Safety First advises against using a hair dryer in a bathroom or near a sink full of water and says its air openings should not be blocked.
Keep the dryer and its plug away from water, leave the air openings clear, and unplug it after use. Stop using a dryer with a damaged cable, sparking or an unusual smell.
These examples illustrate different model features worth checking; a brand name alone does not establish how a particular dryer will perform on your bob.
The Air Power Pro D6555DU combines a short-length-focused concentrator with attachments for other styling routines.
The Helios offers a conventional dryer format centred on focused airflow for a brush-led, smooth bob.
The Supersonic r is a compact-format option for people interested in manoeuvrability and attachment-specific controls.
The SpeedStyle Pro HD731UK package is relevant to a straight or wavy bob routine using directed airflow and a styling brush.
These dryers offer different ways to approach a bob at a dry dressing table: some list a concentrator for directed shaping, while packages with a diffuser also allow for a texture-led routine. Check each model’s controls, attachments, plug and cable against your own setup.

A concentrator is the attachment to check if you want to direct air along a brush and work on shorter sections. BaByliss describes the 6 mm × 60 mm concentrator supplied with its Air Power Pro as intended for shorter lengths and fringes; check the attachment supplied with any other model rather than assuming all nozzles are the same.
A diffuser is worth considering if you regularly dry a wavy, curly or coily bob with its natural texture. If your routine is mainly a smooth, brush-shaped fringe and outline, check the concentrator first; if you do both, confirm that the exact package includes both attachments.
No single wattage figure establishes how a dryer will handle your bob-styling routine. Which? considers factors including measured wind speed, ease of use, noise and versatility, so assess the usable nozzle and controls as well as the headline figure.
