Remington S8540 review

The same 110 mm (4.33 in) floating plates on a digital body: an LCD display with nine settings from 150 to 230 °C (302 to 446 °F), a dedicated Pro+ setting at 185 °C (365 °F), a temperature boost, and a keratin and almond oil ceramic coating.

Where it leaves us The S3500 with a screen and a named setting — worth it if you want to see the number.

The same 110 mm (4.33 in) floating plates as the S3500, on a body with an LCD display. Nine temperature settings from 150 to 230 °C (302 to 446 °F), a temperature boost to reach the top of the range quickly, and a fifteen-second heat-up.

The addition Remington puts forward is the Pro+ position at 185 °C (365 °F), which it describes as a gentler styling setting. This page reports the figure and the description and stops there.

One note for anyone comparing prices. Nine of the twelve straighteners here publish a price on amazon.com and three do not — and the three include the ghd Gold and the S3500, which is the model this one is built on. So the comparison this page invites, against its own cheaper sibling, is the one the catalog cannot price for you.

The comparison it can make is less flattering. At $70 this is the dearest straightener on the shelf that publishes a price at all; the eight others run from $14 to $44. It shares its plates, its range and its heat-up with the S3500, so what the difference buys is the Pro+ position and the LCD. Against the American irons, the Arkam at $29 gives twelve heat levels from a 250 °F floor where this gives nine from 302 °F, and the CHI at $44 gives none, being fixed at 392 °F. Nine steps on 110 mm (4.33 in) floating plates is a sound specification. At twice the price of twelve steps, the plates have to be the reason. The S3500, BaByliss ST393E and ghd gold are the other European references on the hair straighteners shelf, and what the temperature dial means explains the range.

What people ask about this

What is the Pro+ setting?

Remington publishes it as a dedicated 185 °C (365 °F) position, described as a gentler styling setting. The figure is the manufacturer's and it is reported here as published. Whether it suits your hair is a question for the manual and for a hairdresser.

Our score
