The more temperature control options you have, the more control you'll have over the heat you'll be applying to your hair. Keep in mind, any type of heat styling can be damaging to your strands, so you want to take care not to use too much high heat, especially if you're styling daily. Flat irons that have lower temperature options that start around 250 degrees Fahrenheit are ideal for those with thin, damage-prone hair. If you do have thick hair, higher heat settings can help straighten those curls. To help prevent damage, you should start with lower heat first, and then only increase as needed. Keep in mind, anything above 400 degrees has the potential to damage your hair. Even those with coarse, curly hair should stay within the 350-400 degree range to be safe.

This is an absolute MUST HAVE for anyone with natural black hair. We talked earlier about how dangerous low-end flat irons can be for anyone with type 3 or type 4 hair, and this is precisely why. If you fit into those hair types, any straightener without an adjustable temperature control is likely to be way too hot for your hair to handle – especially for long-term use.


With so many models and styles to choose from, it can be hard to find the right hair straightener for your medium or long hair. That’s why we love the Cloud Nine Original Flat Iron! This straightener is ideal for users with medium to long hair; this hair straightener can tame even the most stubborn tresses. Featuring 1-inch plates and low, medium, and high heat settings, this flat iron is ideal for anyone with thick or lengthy hair.
The question is, does it live up to all the hype? There are more than 30,000 reviews on Amazon, 70% of these reviews give a 5-star rating, and 14% give a 4-star rating. According to the numbers, the HSI Professional truly is a high-quality product that is well-deserving of the attention it's been given. Buyers love how quickly the HSI Professional heats up, what it does for their hair, and how easy it is to use— even on short hair.
In the end you want to make sure that your hair is protected no matter what hair straightening treatment or tools you choose. Many hair straighteners are for daily discipline and upkeep. There are lotions, sprays, balms, serums and cremes to help you tame wavy or curly hair, control frizz or protect from humidity. Several hair straightener creams offer protection against damage from hair dryers and hot irons. Look for the hair products that will protect your hair and keep it smooth, shiny and silky.
Many hair straighteners feature a visual interface to alert you when the device is getting a bit too hot for comfort or when it has surpassed the ideal temperature for your hair. With the T3 Micro Single Pass Flat Iron, you can expect the same visual cues with the bonus of sound alerts as well! That’s right; this flat iron will actually tell you when it reaches its ideal temperature or when it is about to shut off automatically after one hour. Now that’s some hot tech!
When you apply heat to your hair, which is not a living thing, you’re essentially cooking it. And, just like food, it’s easy to overdo it. Short of actually searing your hair, you still run the risk of drying out each strand, which can lead to breakage and split ends over time. Every head of hair is different, and each type of hair has an optimal flat-iron temperature. Some locks need extremely high temperatures to relax — coarse hair or those with kinky hair need 380 degrees F or above. Others need hardly any heat at all — fine or damaged hair should be good below 300 degrees.

Featuring the same 1.25-inch plates CHI users have loved for years, the new CHI G2 Ceramic and Titanium Flat Iron make it easier to style longer hair! If you’ve ever tried to use a non-professional hair straightener on your hair, then you know just how quickly the process can become a literal pain! From hand strain to sore wrists and arms, most hair straighteners stick to old adage of “beauty is pain.”
This lesser-known brand made a great impression when it was available on Amazon (you can now buy it at TerresaBeauty.com), where the majority of reviewers gave it five stars. "It allows my hair to glide so smoothly through the plates, never snagging it," says one shopper. "I can straighten or curl with this straightener and it works great," says another.
4. The button placement is very similar to the Remington flat iron. When the iron is powered on, quickly press the power button 2 times and a small lock icon will appear on the digital indicator under the Fahrenheit symbol. When the lock icon is visible you cannot change the temp or turn it off by accidentally pressing the buttons. To unlock, quickly press the power button 2 times again and the lock icon will disappear.
The two strips of silicone atop Bio Ionic’s flat iron plates seem silly, but they serve an important purpose. By buffering the outer edge of the plates, they reduce your chances of hair snags. They also force you to glide the flat iron more slowly through your hair (they are called speed strips, after all). While the slower technique maximizes shininess and smoothness, the speed strips can become a bit of an obstacle if your hair is thick.
