The Amory REVOLUTIONARY BLACK is a hair straightener from Amory London that pairs infrared heat with tourmaline plates. It is aimed at people who straighten often and want smooth, less frizzy results. Whether it is worth the money depends on how often you use heat, your hair type, and how much you value those features over a standard ceramic iron, so below we explain what they are and who they suit.

What the Amory REVOLUTIONARY BLACK offers

Two features set this straightener apart from a basic flat iron:

Infrared heat. Brands that use infrared say it warms hair more evenly than plates alone, so you can style with less surface heat. That is the maker’s claim, and we cannot tell you how much difference it will make on your hair.
Tourmaline coated plates. Tourmaline is a mineral used on many straighteners. It is marketed as releasing negative ions that help smooth the cuticle and reduce static. In practice, a smooth coated plate glides more easily and snags less than a rough one.

Before you order, check the listing for the details that matter day to day: plate width, the temperature range and how you set it, heat-up time, whether it switches itself off, cord length and swivel, and the voltage if you plan to travel. Those details, not the heating technology, decide how the tool fits your routine.

How to judge any straightener

Whatever you buy, these points are worth comparing:

Feature	Why it matters
Plate width	Narrow plates suit short hair and fringes. Wider plates cover long, thick hair faster.
Adjustable temperature	Fine or damaged hair needs lower heat than thick, coarse hair. A clear display helps you stay consistent.
Plate coating	Ceramic, tourmaline and titanium all aim to glide smoothly and spread heat evenly.
Floating plates	Plates that flex slightly keep even pressure on the section you are styling.
Auto shut-off	A safety feature if you are ever unsure whether you unplugged it.
Weight and grip	A heavier tool can tire your wrist on long styling sessions.

Who the Amory REVOLUTIONARY BLACK suits

We would consider it if you:

Straighten several times a week and want a tool built for regular use
Have medium to thick hair, or hair that frizzes easily
Want a smooth plate coating that glides through without snagging

It makes less sense if you rarely use heat, have very fine hair that straightens easily at low heat, or mainly want curls and waves. For curls, Amory also sells the Korean Edition curlers: the Korean curling iron in a 19mm barrel for tighter curls and the Korean Edition curler in a 25mm barrel for looser waves.

Using a straightener with less damage

No straightener is damage free. Heat changes the hair’s structure every time you use it. These habits limit the harm:

Dry your hair fully first. Straightening damp hair turns water into steam inside the strand.
Use a heat protectant on every section before you style.
Start at a low setting and only go higher if your hair does not respond. Fine and damaged hair need the least heat.
Work in small sections so each one needs fewer passes.
Keep the plates moving. Holding them in one place is how hot spots and breakage happen.
Take breaks from heat when you can, and trim split ends.

For a pre-styling treatment, Amory sells the Back to Life hair serum. Check its label to see whether it is meant as a heat protectant or as a finishing serum, and use it as directed. Keeping a bottle of Back to Life serum next to your straightener makes it easier to remember before every session.

Care and cleaning

Product build-up on the plates makes them drag and heat less evenly. Once the tool has cooled down to just warm, wipe the plates with a soft, damp cloth. Avoid abrasive cleaners or scrubbing pads, which can scratch the coating.

Let the straightener cool fully on a heat-resistant mat before you put it away. Wrap the cord loosely instead of winding it tight around the handle, which strains the wire where it enters the tool. If you travel with it, use a heat-proof pouch and check that it works on the local voltage.

Is the Amory REVOLUTIONARY BLACK worth it?

It is worth a look if you straighten often, have thicker or frizz-prone hair, and want a tool with a smooth tourmaline plate and adjustable heat. If you straighten only now and then, or your hair is fine and easy to style, a simpler ceramic straightener may do the job just as well for less.

If you would rather add volume and movement than straighten, an automatic curler like the Korean automatic hair curler is a different approach.

Questions

Does the Amory REVOLUTIONARY BLACK work on thick, coarse hair?

It is aimed at people who straighten often, including those with thick or frizz-prone hair. For coarse hair, work in small sections, use a heat protectant, and raise the temperature only as far as you need.

What temperature should I use?

Start low and only go higher if your hair does not respond. Fine or damaged hair needs the least heat and thick, coarse hair usually needs more. Check the listing for this tool's exact temperature range.

Can I use the Amory straightener on damp hair?

No. Dry your hair fully first. Straightening damp hair turns water into steam inside the strand, which can damage it whatever heating technology the tool uses.

Is infrared better than a ceramic straightener?

Brands say infrared heats hair more evenly with less surface heat. We cannot confirm how much difference that makes for your hair. Technique, temperature and a heat protectant matter more than the heating type.

What is the warranty on this tool?

Check the product page, the packaging or Amory London's support page for the current warranty terms, and keep your proof of purchase.
