2 Essential Tips on How to Use Your Automatic Curler Correctly

The two things that decide whether an automatic curler gives you curls that last are simple: curl bone-dry hair in even sections, and let each curl cool completely before you touch it. Get those right and an auto curler does the rest. Here is how to apply both, the full step-by-step routine, and the styling choices that shape the final look.

Tip 1: dry hair, even sections

An automatic curler sets a curl with heat, and heat cannot set a curl in damp hair, the water just boils off and the curl drops. Start with fully dry hair, apply a heat protectant, and feed even, sensible sections into the barrel. Sections that are too thick will not heat through, so they never really set; about 2 to 3cm wide is the sweet spot. Freshly washed? Read curling after the shower first.

Two prep habits make this tip work harder. Day-old hair usually holds a curl better than freshly washed hair, so styling the day after a wash is easier than fighting squeaky-clean strands. And if your hair is flat or static before you start, a quick blow-dry through the roots adds volume and knocks out the static that makes sections misbehave.

Tip 2: let the curl cool

The curl sets as it cools, not while it is hot. When the curler releases a warm curl, let it drop and cool without brushing or pulling it straight away. Once every curl is cool, rake through gently with your fingers for a soft, lasting finish. This single step is the most common reason curls hold or fall.

The full routine, step by step

1. Choose your heat: lower (around 170°C) for fine or colour-treated hair, higher (up to 230°C) for thick or coarse hair.
2. Take a small, even section, about 2 to 3cm wide, and clip the rest away.
3. Feed the ends into the barrel chamber and let the curler wrap the hair for you.
4. Hold until it signals the curl is set (the TNS Auto Curler beeps).
5. Release gently and let the curl drop and cool without touching it.
6. Work around your head, then once everything is cool, rake through with your fingers and set with a light mist.

Most people finish a full head in 10 to 20 minutes once they have the rhythm; very long or thick hair can take closer to 30. That is still faster than a wand, because the wrapping and timing are automatic and every curl matches.

Shaping the look you want

• Direction: curling away from your face is the most flattering; alternate directions for a natural, undone finish.
• Curl size: a shorter timer and tighter setting gives defined ringlets; longer, looser settings give soft waves. Smaller sections curl tighter, bigger sections curl softer.
• Texture: once cool, scrunch gently with your fingers to break the curls up, and add a small amount of curl-defining product if your hair needs hold.
• Hairspray: keep it light and use a non-aerosol mist; a slight spritz holds the bounce, while a heavy coat dries the hair out and drags the curl down.

Put it together

Even heat plus a real cool-down is exactly what the TNS Auto Curler is designed around: a Diamond-Titanium-Ceramic barrel spreads heat evenly, the open barrel's wide tooth spacing keeps hair feeding through without tangling, and it signals when each curl is set, so you get curls that last 3 days, not 3 hours.

FAQs

Why do my auto-curler curls fall out?
Almost always damp hair or touching the curl before it cools. Curl dry hair and let each curl cool fully before you rake it through. The deeper diagnostics are in why curls fall out and how to fix it.

How do you use an automatic hair curler?
Feed a small section of dry hair into the barrel, let it wrap and time the curl, then release and let it cool. Match the heat to your hair type.

Should I use heat protectant with an automatic curler?
Yes, every time. It shields the strand and helps the curl set cleaner, so it lasts longer.

How big should my sections be?
Even and moderate, about 2 to 3cm. Sections that are too thick will not heat through, so the curl never fully sets.

Which direction should I curl?
Away from your face is the most flattering; alternate directions for a more natural look.

How do I keep the curls soft, not crunchy?
Finish with your fingers, not a brush, and use only a light-hold mist rather than heavy product.
