Takes time to style

These are the 11 best flat irons specifically designed for coarse hair. But before you choose one, consider the following factors.

How To Choose Flat Iron For Coarse Hair

Temperature Setting: It is important that you choose a flat iron with a high-temperature setting for coarse hair. Denser and thicker hair means you need to pass your iron multiple times to get straight hair. This is rather a time consuming and difficult task. Choose a flat iron with a high warm-up temperature that reaches above 380o

Plate Type: Usually, titanium plates heat faster than ceramic plates. Titanium plates also retain heat longer and work best with thick hair. Ceramic plates help with even heat distribution and minimize hair damage caused due to heat. Certain plates are an infusion of both the plate types. Hence, choose as per your needs.

Negative Ion Technology: Negative ion technology helps your hair have a frizz-free and sleek look. It works by drawing moisture from your cuticles and sealing it in your hair strands. Ensure the flat iron has this technology.

Size: Coarser hair calls for wider plates. Look for a straightener with floating plates as they hold a larger hair volume. Also, make sure your plates are more than 1 inch thick for optimal results.

What Safety Features Should A Flat Iron Have?

Automatic Shut-Off: Sometimes, in a hurry, we tend to forget to switch off our heating tools. This can cause serious fire hazards. Look for flat irons with an automatic shut off feature.

Heat-Resistant Gloves: Coarse hair takes a long time to style, and the iron tends to get hot while styling. It is always recommended to wear heat-resistant gloves for safety.

Sound Indicator and LCD Display: Sound indicators and LCD displays help you monitor the ideal temperature so that you will not burn or scorch your hair.

Tips For Straightening Coarse Hair

Always Use A Heat-Protectant Spray: Not using a heat protecting spray will cause heat damage to your hair. It also may result in hair breakage and frizz, and may even burn your hair. Always use a heat protectant spray while styling your hair to prevent such damage.

Move From The Roots To The Tips: It is advised to straighten your hair starting from the roots to your hair tips. This gives an even, sleek, and straightened look.

Protect Your Hair From Excessive Heat: Make sure to set the exact temperature ideal for your hair type.

Use A Brush To Comb Your Coarse Hair: Using a comb while straightening your hair will cause static friction and flyaways. You may instead use a paddle brush while straightening – it gives a more convenient styling experience.

Mistakes To Avoid

Not Cleaning Your Flat Iron Properly: Not cleaning your flat iron can leave product deposits on your scalp and ruin your straightening plates. These deposits may also react with your hair and cause damage.

Not Drying Your Hair Well: Using a flat iron directly on wet hair will damage your hair strands. Always dry your hair thoroughly before straightening your hair.

Using The Wrong Size Flat Iron: Coarse hair needs a wider plated iron. A flat iron with smaller plates will take a long time to style your hair and may not give you the desired results.

Holding The Appliance In The Same Spot For Too Long: Do not hold your heat tool for a prolonged time in the same spot as it may scorch your hair.

She comprehends the users’ requirements and analyzes the market and user reviews before selecting the products. Shiboli has curated this list of flat irons suitable for coarse hair types after considering their effectiveness, affordability, and other required aspects. She has also included their factors and some safety aspects to help you make an informed decision. Can you use a flat iron to curl your hair? Yes, you can use a flat iron to curl your hair. There are certain techniques by which you can style your hair into beachy waves and curls. Can I use too much heat? Excessive heat can scorch your hair. It is important you use the ideal heat setting depending on your hair type – 250o F for very thin hair, 300o to 370o F for medium hair, and 370o to 420o F for thick, coarse hair. What is the difference between ceramic and non-ceramic plates? Ceramic plates straighten your hair by heating it from the inside-out, while non-ceramic plates, such as titanium, straighten by heating the hair surface. Ceramic plates also take a longer time to heat but cause minimal damage compared to non- ceramic plates. Should I use a heat protectant to flat iron my thick hair? Not using a heat protectant spray will cause heat damage to your hair, resulting in hair breakage and frizz. Your hair may also experience burns. Always use a heat protectant spray while styling your hair to prevent such damage. Can I use a flat iron regularly? Regular straightening will damage your hair and make it feel brittle and dry. It is okay to straighten your hair once in a while (make sure you use a heat protectant spray before styling). Does flat iron cause hair loss? No. Using a flat iron has no direct connection with hair fall. But, flat iron uses heat to alter the internal hair structure and break the hydrogen bonds. As a result, the hair weakens. Therefore, always use a heat protectant on your hair before straightening it with a flat iron to prevent hair damage. How long does it take to straighten coarse hair? Depending on the length of your hair, it will take 10 to 30 minutes to straighten coarse hair.
