Best Blow-Dry Brushes Under $150 in Australia

What makes a blow-dry brush easier to use for smooth hair

Start with handling: barrel size, grip, published weight, switch position and a swivel cord. You need to guide small sections without stretching your wrist or repeatedly catching the controls. A specification sheet cannot establish how comfortable a tool will feel in your hand.

For a smooth finish, follow the maker’s preparation and sectioning instructions and use manageable sections. Compare lower heat and airflow choices before maximum wattage. Ionic or ceramic claims do not prove a better finish or damage-free styling; BuyCheck has not measured those results.

Oval vs round barrels

An oval barrel offers a broad surface for smoothing with lift and curved ends. A smaller round barrel is worth comparing for fringes, short layers or more defined shaping. Shape and diameter are separate checks: an oval brush is not automatically smaller or easier to manoeuvre.

Mermade specifies a 60mm oval barrel; Hydraluxe specifies an oval barrel without a diameter in the source checked. The AS7700AU lists 50mm, 38mm and 25mm brush heads. Treat these as layout choices, not a performance ranking.

Fine/short hair vs thick/long hair needs

Fine hair and short hair are different considerations. For fine strands, prioritise a lower heat option and gentle handling; for short layers or a fringe, compare a smaller head that can reach the section you want to shape. Fine, long hair may still suit a larger barrel.

For thick or long hair, compare head size, grip and how you will divide the hair into sections. A concentrator can support a separate pre-drying step if the instructions allow it. Do not assume a higher wattage or larger barrel will dry thick hair faster: we have not tested drying time.

Heat and airflow controls

Check whether heat and airflow can be adjusted separately or only through paired settings. Count the usable combinations rather than assuming that three settings provide independent controls. A cool shot is a control feature, not a removable attachment.

Mermade publishes three paired heat/speed settings at 60°C, 95°C and 115°C. Hydraluxe lists three heat and two speed settings, a cool shot and a Hydracare lower-heat setting. AS7700AU lists two heat/speed settings and a cool shot. Follow each manual and start with the lowest useful heat for your hair.

Attachment bundles: cool shot, concentrators and diffusers

A fixed brush avoids swapping heads. An interchangeable bundle is useful when its smaller brushes, paddle brush or concentrator match steps you expect to use. Check that attachments lock securely, how they are removed after cooling, and what needs storing or cleaning.

AS7700AU lists three brush sizes, a paddle brush, a drying concentrator and Root Boost. Its published bundle does not list a diffuser. If preserving natural curls is part of your routine, verify diffuser inclusion and compatibility separately; do not assume every airstyler includes one. Neither fixed oval brush is an interchangeable attachment bundle.

Mermade Blow Dry Brush, Sleek Black: fixed oval layout

The manufacturer lists a 60mm oval barrel, 400g weight, three heat settings, a 1200W motor and 2.5m swivel cord. Its Australian listing states 220–240V, an AU plug and a two-year warranty.

Compare this layout for a simple fixed-brush routine. The broad barrel may be less convenient around short layers; that is a fit-based inference, not a result from hands-on testing. Follow the maker’s towel-dried-hair instructions.

Remington Hydraluxe AS8901AU: fixed oval controls

The Australian manufacturer source lists an oval barrel, 1200W, three heat settings, two speed settings, cool shot, swivel cord and a five-year warranty. Hydracare is described as a lower-heat setting.

Compare its controls with Mermade if you prefer a fixed oval brush. The source checked does not establish barrel diameter, handling weight or real-world smoothing performance; verify missing details on the exact model before buying.

Remington Blow Dry & Style AS7700AU: interchangeable heads

The maker lists 50mm mixed-bristle, 38mm retractable-bristle and 25mm mixed-bristle brushes, a paddle brush, concentrator and Root Boost. It also lists 1200W, two heat/speed settings, cool shot, a 3m swivel cord and a three-year warranty.

Compare this model if smaller heads or a separate pre-drying step matter to your routine. More attachments mean more parts to swap and store; attachment count does not prove easier use or a better finish.

What to verify before buying

Confirm the exact Australian model and bundle, barrel dimensions, heat/airflow combinations, included attachments, weight, grip and cord length. Read preparation, cleaning and cooling instructions. Check the ratings label and Australian plug rather than assuming an overseas listing is equivalent.

Verify seller, current availability, warranty, returns and total delivered cost. Under $150 is a shopping budget, not a guarantee that every listing or checkout total qualifies. We do not provide live prices, stock guarantees, test scores or endorsements.
