Remington Shine Therapy Hair Dryer Brush (AS9550NA) review

A corded hot-air brush whose exact product page promises a sleek, straight finish as well as a blowout. Its 2.4-inch oval head is not a plate measurement, and the linked manual illustrates volume styling rather than a dedicated straightening routine.

A dryer-brush hybrid, not a flat iron

The AS9550NA sits near the edge of this category for a reason. Remington calls it a Shine Therapy Hair Dryer Brush, and its linked booklet names the AS9550NA (AS20A) as a 1100 W air styler. There are no opposing plates. Instead, the pictured oval head has mixed bristles and airflow passes through the barrel. The product page says to rough-dry with a concentrator and then use the oval brush for either a sleek, straight finish or a bouncy blowout. That explicit straight-finish mode is why this dryer/brush hybrid is included alongside dedicated straighteners; it should not be mistaken for a plate iron or a tested substitute for one.

The distinction also matters when reading the manual. Its English instructions say to squeeze out excess moisture, use the pre-styling nozzle until the hair is about 80% dry, and then move the oval brush down a section. The illustrated method is for lifting at the roots and creating volume. The booklet does not provide a separate, step-by-step straightening technique, although the product page makes that mode claim. These sources describe adjacent ways to style with the same tool, not independent proof of a particular finish.

Heat control is coupled to airflow

The manual labels its selector for high heat/speed, low heat/speed and cool air. That is more than one heated level, so the documented plan is user-adjustable rather than a single fixed target. But the booklet does not publish temperature values, and heat and airflow speed change together. Anyone who needs a specific temperature range or a plate-contact routine should compare a dedicated adjustable iron instead. The product page describes two heat/speed settings plus a cool shot; those control labels, rather than an unverified maximum-temperature figure, are the useful comparison facts.

Remington describes a 60 mm (2.4-inch) oval brush, mixed thermal bristles and a removable pre-styling nozzle. That large rounded head may be relevant to a blowout routine, but it is not a 2.4-inch straightening plate. The finder treats plate width as a plate-only field, so AS9550NA cannot pass any entered maximum-width condition. If a narrow plate is needed to reach close to a hairline or to work a small section, this brush head is a different tool geometry rather than a wider or narrower plate option.

Power and practical limits

The booklet states ordinary household current of 125 VAC, 60 Hz, and identifies a polarized plug and an ALCI safety device. This supports a corded US operating plan, not universal-voltage operation. A plug adapter cannot convert voltage; check the rating on the exact tool and the destination supply before travel. The source page and booklet do not state a numeric cord length. “Swivel cord” is a feature, not a measurement, and cannot establish whether the cable reaches a particular mirror or outlet. The manual says not to use an extension cord.

The model-specific instructions also say to keep air inlets clear, clean the removable filter grille, and allow hot attachments to cool before removing them. The product page describes a three-year limited warranty. Confirm the exact AS9550NA code, the included brush and concentrator, warranty terms and current instructions with the seller; gallery photos and package contents can vary. The manual does not document an automatic shutoff time, so none is assumed here.

Who should compare it—and who should look elsewhere

Consider AS9550NA if you are comparing a dryer-brush hybrid that the manufacturer says can produce a straight finish, want a corded tool with two heat/speed levels plus cool air, and are comfortable beginning on towel-damp hair. It may be a poor match if you require heated plates, a documented plate width, a named temperature in degrees, universal voltage or a verified cable reach. In particular, do not read the 60 mm head dimension as a plate-width answer or treat the maker's finish claim as our own result.

It differs from Remington's CB7403, CB5750NA and CB9350US: those are dry-hair heated-bristle straightening brushes with three named temperature settings, while AS9550NA uses a 1100 W dryer handle, airflow and damp-hair preparation. See the cord-and-setup guide and keep the exact model and household-voltage label in view. This is a source-based comparison, not a hands-on review or a promise that any tool will produce a particular result on an individual routine.
