How to Use an Automatic Hair Curler? | Step-By-Step Curls

An automatic hair curler is a motorized styling tool that rotates a section of hair inside a heating chamber, so you don’t have to wrap strands around a barrel yourself. The process is simple: detangle dry hair, insert a small section, choose your heat and direction, hold the button, wait for the beep, and slide the tool down. With the right technique, you get consistent curls in under ten minutes. Read on for the complete step-by-step method, including tips for natural-looking results and mistakes to avoid.

How Do You Use an Automatic Hair Curler?

Using an automatic curler involves a short prep phase followed by a simple load-and-release rhythm. The basics are the same across corded and cordless models, though button layouts vary slightly.

Prep Your Hair

Start with completely dry, combed hair. Using any automatic curler on wet or damp strands can cause uneven styling or damage. Apply a heat protectant and brush through to remove tangles. For longer or naturally curly hair, work in smaller sections—around 1 to 1.5 cm—to prevent tangling. If your hair is very thick, keep each section smaller than the chamber opening to avoid jams.

Power On and Set the Heat

Plug in the curler (or charge it, for cordless models). Most devices have a Power/Mode button you press and hold for about 1.5 to 2 seconds to turn on. Use the Menu button to adjust temperature, curl direction, °C/°F display, and timer length. Default temperature is often Mode 3—good for medium hair. For fine or damaged hair, choose a lower heat setting; for thick or coarse hair, use a higher one.

Load a Section of Hair

Take a clean section of hair, ideally no wider than about 2 cm. Hold the curler upright with the chamber’s open part facing your head. Place the ends of the hair into the chamber opening, then press and hold the Left or Right Curling Button (or Start) until the hair is drawn in automatically.

The left button curls hair from one side; the right button curls from the other. Hold the button until you hear beeps indicating the timed curl is done—usually 10–15 seconds. Some models use a single final beep, while others use four quick beeps. Let go of the button, then smoothly slide the tool straight down and away from the curl. Don’t pull sideways or twist, as that disrupts the curl’s shape.

How Do You Get Natural-Looking Curls?

Choose curl direction before you start. L’Oréal Paris’s curling guide notes that curling hair away from your face is often the most flattering option. For a softer, more natural look, alternate directions—curl one section away from your face, the next toward it. Let each curl cool in your palm briefly before releasing it, then finish with a light hairspray. If you want tighter curls, use a longer timer; for loose waves, shorten the timer and use larger sections.

What Mistakes Ruin Automatic Curler Results?

The most common failure is feeding in too much hair at once, which causes jams and uneven heat. Another frequent error is pulling the tool away sideways instead of sliding it straight down after the beep, which stretches the curl out of shape. Touching curls immediately after releasing them is also a problem—both the hair and the chamber stay hot for a few seconds, and handling them too soon can both burn you and flatten the result. Finally, never use the device on damp hair; wait until hair is completely dry to avoid damage and poor curl formation.

Safety Notes

Many cordless models have an auto-shutoff feature—one manual notes the appliance turns off after five minutes if forgotten. If you have naturally curly hair, expect to use more, smaller sections to avoid tangling, per manufacturer guidance.
