A wide curling iron can make loose waves faster, but the wrong barrel or heat range can leave long hair uneven or make curls fall flat. The Conair Double Ceramic 1 1/2-Inch Extra Long Barrel Curling Iron CD710L is built around a 6-inch-long barrel, 30 heat settings up to 375°F, and double ceramic heat for soft waves and loose curls. Its long barrel is especially useful when you have medium to long hair, although the 1.5-inch diameter is less suited to tight, defined curls. This review explains the features, limitations, safety considerations, and styling situations that matter before you buy.
Quick Verdict
Rating: 8.4/10, Recommended with caveats
Best For: Medium to long hair when you want soft waves, loose curls, or added body.
Bottom Line: The 6-inch extra-long barrel and broad heat range make this Conair iron practical for styling longer sections of hair. Its main tradeoff is the 1.5-inch barrel, which favors relaxed waves rather than small or tightly defined curls.

What Is the Conair Double Ceramic Curling Iron?
The Conair CD710L is a corded curling iron with a 1.5-inch double ceramic barrel. Unlike the shorter standard version of a wide curling iron, this model uses a 6-inch extra-long barrel. That gives you more heated surface for wrapping longer sections of hair without stacking as much hair over itself.
The barrel size is designed mainly for big soft waves, loose curls, bends, and body. It is a better match for medium and long hair than for very short styles because you need enough hair length to wrap safely around a 1.5-inch barrel.
Conair gives you 30 heat settings up to 375°F, plus Turbo Heat for sections that resist styling. The combination gives you more control than an iron with only a few preset temperatures, but you still need to choose heat carefully for your hair condition and texture.
Power your essentials anywhere with a 999Wh pure sine wave power station delivering up to 1000W continuous with 2000W surge. It supports fast charging via USB-C PD 60W and USB-A QC 18W, plus simultaneous output for multiple devices through AC, USB, wireless, and car/DC ports. Recharge using AC, car, or solar with a built-in MPPT controller and dual cooling fans, while the upgraded battery management system protects against surges, short circuits, and overheating.
SOFT WAVES, LASTING CURLS, ALL-DAY HOLD: The Double Ceramic 1½-inch barrel creates soft waves, loose curls, and polished volume on medium, long, fine, or thick hair, while even ceramic heat helps eliminate hot spots for smooth, long-lasting results with less damage.
BIG, SOFT WAVES THAT LAST: This double ceramic curling iron heats up fast and delivers even heat for beach waves, loose curls, and full-body volume with less frizz and lasting shine on fine, medium, and coarse hair.
Who Should Buy It?
Best For
- Medium to long hair that benefits from the 6-inch barrel.
- Soft waves, loose curls, rounded ends, and full-body styles.
- Buyers who want adjustable heat instead of one fixed temperature.
Skip If
- You mainly want small ringlets or tight curl definition.
- Your hair is too short to wrap comfortably around a 1.5-inch barrel.
- You specifically want a lightweight compact iron for a small travel bag.
Before You Buy: The 1.5-inch barrel is intentionally wide. It creates relaxed curls and waves, so choose a smaller barrel if tight curls are your main goal.
How the 6-Inch Extra-Long Barrel Changes Styling
The barrel length is one of the biggest reasons to choose this model. Long hair can crowd a short barrel, forcing you to overlap sections or curl the same area more than once. The 6-inch barrel gives you more room to spread a longer section across the heated surface.
This can make the iron easier to use for shoulder-length hair and longer styles, especially when you want a smooth bend through the middle and ends. You can also work with slightly longer sections without packing several layers of hair onto one spot.
Barrel length does not change the curl diameter. The 1.5-inch width still produces a broad curl pattern, so expect soft movement rather than compact spirals.
How Does Double Ceramic Technology Make Curling Easier?
Conair describes the barrel as using double ceramic technology to distribute heat evenly and help reduce hot spots. More even contact can make it easier to curl a section consistently rather than overheating one area while another receives less heat.
The ceramic barrel is also intended to support smoother styling and frizz control. Results will still depend on your hair texture, humidity, product use, heat level, and technique, so the coating should not be treated as a guarantee of frizz-free hair.
Heat Settings and Temperature Control
You get 30 temperature settings with a maximum of 375°F. That range lets you adjust the iron rather than using the highest heat on every section. Fine, fragile, bleached, or damaged hair generally calls for more caution with heat, while harder-to-style hair may need a higher setting to form a curl.
The iron also has Turbo Heat for stubborn areas. This is best treated as an occasional styling aid rather than a reason to apply maximum heat repeatedly.
Pro Tip: Start below the maximum setting and increase heat only when your hair is not forming a curl. Using smaller, fully dry sections can improve results without automatically moving to the hottest setting.
Controls, Cord, and Everyday Handling
The CD710L includes recessed buttons, which help reduce accidental button presses while you are rotating and repositioning the iron. A 5-foot swivel cord gives you useful movement around a mirror or vanity without the cord twisting as easily during repeated turns.
The listing gives the iron a weight of 1 pound. That is worth considering if you have very long or thick hair and expect to hold the tool up for extended styling sessions.
A cool tip provides a designated cooler area for steadier handling, but the barrel itself becomes hot enough to burn skin. Always treat the barrel, clamp area, and nearby heated surfaces as burn hazards during and immediately after use.
Travel and Safety Features
The curling iron supports dual voltage, which makes it more practical for international travel than a single-voltage styling tool. You may still need the correct plug adapter for the destination. An adapter changes the physical plug connection, not the electrical characteristics of an incompatible appliance, so check destination requirements before use.
The automatic shutoff feature provides an extra layer of protection if the tool is accidentally left on. It should not replace the habit of turning the iron off and unplugging it after styling.
Use the iron only on dry hair unless the manufacturer specifically states otherwise. Keep the appliance away from water, avoid touching the heated barrel to your scalp or skin, and allow it to cool before storing it.
How It Performs in Real Use
For Long Hair
This is where the CD710L makes the most sense. The long barrel gives you more room to position a full section without crowding the hair toward one end. That can make loose curls and waves easier to form on lengths that feel awkward with a standard short barrel.
For Loose Waves
The 1.5-inch diameter creates a broad curve. Curling sections away from your face and letting them cool before separating them can give you softer waves with visible movement rather than tight ringlets.
For Adding Volume and Shape
You can use the barrel to add bend through the lower half of your hair or create rounded ends. This makes the tool useful even when you do not want a fully curled hairstyle.
For Harder-to-Style Sections
The adjustable heat range and Turbo Heat give you options when certain areas do not hold shape easily. Use the extra heat carefully, especially around previously processed or damaged sections.
How to Use the Conair Curling Iron for Better Results
Start with completely dry, detangled hair. Divide your hair into manageable sections so each section can contact the barrel evenly instead of creating a thick bundle with an underheated center.
Open the clamp, position the hair carefully, and roll the iron without allowing the hot barrel to touch your scalp. A smaller section generally creates more defined shape, while a larger section tends to produce a softer result.
For a less uniform finish, alternate the direction of curls on different sections. Around your face, many people prefer directing the curl away from the face for a more open look.
After releasing each curl, let it cool before brushing or pulling it apart. Cooling gives the hair time to settle into its new shape. Follow the manufacturer’s instructions for safe operating times and temperature selection.
Pros and Cons
Pros
- 6-inch extra-long barrel gives longer hair more usable styling space.
- 1.5-inch diameter works well for soft waves and loose curls.
- 30 heat settings provide more temperature control.
- Turbo Heat can help with harder-to-style sections.
- Dual voltage, auto shutoff, cool tip, and swivel cord add practical convenience.
Cons
- The wide barrel is not ideal for tight curls or small ringlets.
- The extra-long design can feel larger than a compact curling iron.
- Getting the best heat setting may take some trial and error for your hair type.
Is It Worth the Price?
The Conair CD710L makes the strongest value case for buyers who specifically want a wide, extra-long curling iron rather than a compact iron for tight curls. The combination of a 6-inch barrel, 30 heat settings, Turbo Heat, and practical safety features gives you a useful feature set for everyday loose-wave styling.
You get the most value if your hair is long enough to benefit from the extended barrel. If your hair is short or you mainly want defined curls, a smaller-diameter or shorter curling iron will likely match your styling goals better.
How It Compares to Alternatives
Conair sells the Double Ceramic line in several barrel sizes, including smaller options that create tighter curves. A standard 1.5-inch Double Ceramic model is also worth comparing if you like the same broad curl diameter but do not need the added barrel length.
The CD710L makes the most sense when long-barrel coverage is the priority. If curl definition matters more than styling long sections efficiently, a 1-inch or 1.25-inch model may provide the tighter shape you want.
Frequently Asked Questions
Is the Conair CD710L good for long hair?
Yes. Its 6-inch extra-long barrel gives you more room to spread medium or long sections across the heated surface. That can make wrapping long hair easier than with a shorter barrel.
What kind of curls does a 1.5-inch barrel create?
A 1.5-inch barrel is best for loose curls, soft waves, bends, and body. It is not the best size when you want tight ringlets or very defined curls.
How hot does the Conair CD710L get?
The verified listing states that it has 30 heat settings up to 375°F. You do not need to use the maximum setting for every hair type, so begin conservatively and increase only as needed.
Can you use this curling iron on wet hair?
You should use the curling iron on dry hair. Water and a hot electrical styling appliance are a poor combination, and wet hair may also respond differently to direct high heat.
Does the Conair curling iron have automatic shutoff?
Yes, automatic shutoff is listed as a feature of the CD710L. You should still turn the iron off and unplug it when you finish styling instead of relying on automatic shutoff as your normal routine.
Can you travel internationally with the Conair CD710L?
The product is listed as dual voltage, which makes it suitable for a wider range of electrical systems. You may still need the correct physical plug adapter for the country you visit, so check local outlet requirements before traveling.
How should you clean and store the curling iron?
Unplug the iron and let it cool completely before cleaning or storing it. Wipe away styling-product residue carefully with a suitable soft cloth and follow Conair’s care instructions rather than using abrasive cleaners on the ceramic surface.
The Bottom Line
The Conair Double Ceramic CD710L is a strong choice for medium to long hair when your goal is soft waves, loose curls, and body. Its 6-inch extra-long barrel and 30 heat settings are the main advantages, while the wide 1.5-inch diameter makes it less suitable for tight curls or very short hair.
If that wide, relaxed curl pattern matches your styling goals, this model earns a Recommended with caveats verdict.
