What features to consider when choosing a flat iron?

Choosing a flat iron curler is not a task to be taken lightly – not unless you want to end up with a product that will scorch your hair or break down halfway through your very first styling session. With so many options out there, one can easily get overwhelmed.

Not to worry, though: helping you make a smart decision is what this guide is all about! Here are some of the key features to consider when shopping for a flat iron curler:

Temperature settings

If you have little experience in curling hair with a flat iron (or any other heat styling appliance for that matter), picking the one with adjustable heat settings is a must. Every hair texture needs a different temperature range, and it might take you a while to understand which one is yours.

In the meantime, stick to the basics – never go over 420°F, do not hold for longer than 10 seconds, and always apply hair care products.

Plate material

  • Titanium irons are great in every way but their price. They heat up quickly, reach a very high temperature in mere seconds, maintain consistent heat, clean easily, and last long. A rounded flat iron for curls, which plates are made of titanium, will be a fine purchase for users with coarse and thick hair.
  • Ceramic irons (not ceramic-coated, mind you!) are best for people with fine or normal hair. They take a little longer to heat up but preserve heat effectively and disperse it evenly, just like titanium products. They are also less pricey, which is a clear advantage.
  • A tourmaline tool is a decent option for people whose hair tends to be a bit frizzy and unmanageable. Generating negative ions, tourmaline seals hair cuticles and keeps it calm, moisturized, and protected against unnecessary damage.

Overall size and shape

If you seek a truly versatile option, a flat iron and curler with rounded plates should be your first pick. These appliances are capable of straightening your hair into sleek and shiny strands, as well as turning it into beautiful waves and curls without unsightly creases and kinks. Square-edged irons will make short work of smoothening your tresses but might be a little challenging to handle if you use them for curling purposes.

Extra frills

Depending on your needs and budget, there are a couple of cool features you may want your flat iron curler to have, such as:

  • far infrared technology: these irons heat your hair from inside out without damaging its outer layers;
  • floating plates allow you to adjust the grip on your hair properly and ensure tighter contact with it, which leads to heat being spread more evenly;
  • dual- or tri-zone sensor technology is used to make sure heat is dispersed evenly at all times;
  • automatic shut off function guarantees that your iron goes into sleep mode after some time of non-use, so you are less likely to cause an accident if you leave it unattended;
  • dual (universal) voltage is a must-have feature for travelers if you do not want to carry around a voltage converter. Wherever you go on a trip, you can be sure that your straightening/curling iron will work just fine.

Curling your hair with a flat iron: Step-by-step guide

Girl with Paul Mitchell Pro Flat Iron

If willing to give it enough time and practice, you are more than capable of creating picture-perfect beach waves and salon-grade curls with your flat iron. This short 5-step instruction contains all the tips and tricks you will need to get the hairstyle of your dreams.

  • Step 1. Apply a reliable heat-protectant spray to shield your strands from getting scorched or damaged.
  • Step 2. Begin curling the hair that is closer to the nape of the neck and gradually move all the way up toward the hairline. The iron needs to clamp the hair section above its mid-length, or only the ends will be curled.
  • Step 3. Finish the side by curling the section right at the hairline. Repeat with the other side.
  • Step 4. Massage the roots with your fingers to break the curls apart a bit. If you want a more homogeneous finish, use a boar bristle brush to do the job.
  • Step 5. Use a little hairspray on your styled hair to fixate the curls and keep them in place.

Mistakes you can make when curling hair with a flat iron

  • Using the wrong barrel size. Bigger plates are hard to maneuver on shorter hair. As a rule, you will need a 1-inch wide barrel for short and medium hair and a 1.25-inch-wide appliance for long tresses.
  • Using hair oil before curling since it may weigh down your locks.
  • Using a curler on damp hair will simply fry it.
  • Using higher temperatures to set the hair faster will lead to long-term damage, especially if your hair is delicate, colored, or lacking moisture.
  • Keeping an iron on your hair for more than 10 seconds will lead to its becoming scorched and damaged.
  • Not using a heat protectant. Big mistake. Period.

Flat iron vs. curling iron curls

You should decide which of the two heat styling tools to use to get yourself lovely waves and curls based on your experience level, type of hair, styling frequency, budget, etc. While a regular curler will be entirely up to the task at hand (as suggested by its name), a modern flat iron may give more flexibility and spare you the need to shop for a multitude of additional appliances.

Curling irons are easier to manage to make perfectly tight ringlets of the same size, but these devices are limited to just one purpose, which is inconvenient. Flat irons, on the other hand, can be used to create sexy curls, beachy waves, or silky strands that are smooth as glass. The downside here is that using a flat iron for curling requires practice.

Best Curling Flat Iron FAQ

In this section, I decided to provide the most common questions about flat irons for curling hair. Perhaps, the answers to them will help you clarify any uncertainty you might have about these tools.

Is titanium or ceramic better for curling hair?

Choosing between the two should depend on the type of hair you have. Ceramic irons are best for fine, delicate hair prone to damage, while titanium flat iron curlers will manage coarse and thick hair more effectively.

What should I put on hair before flat ironing?

Applying a heat protectant before flat ironing or curling your hair is an absolute must. Apart from that, you might consider using hold products like a thickening mousse or a tad of hairspray to help your future curls last longer.

Can you curl your hair with any flat iron?

In theory, yes. However, the less specialized the tool is, the more time and practice it will take you to manage it. If you want perfect and consistent results fast, you should stick to flat irons that are rounded at the edges or have special curling attachments.

Final Verdict: Which Model to Choose

Flat irons are incredibly handy multipurpose tools that give you an excellent value for the money. If you are new to curling hair with a straightener and want to have an easy learning curve, I recommend setting your eyes on RUSK Engineering Heat Freak as the best straightener to curl hair. It is very manageable, reliable, gets the job done faster than others, and comes with an appealing price tag.
