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.

For better or worse, we are B-U-S-Y nowadays. Running from meeting to meeting and trying to pick up our kids from carpool before soccer practice, it’s no wonder that we often place ourselves at the bottom of our daily priority list. This mindset typically carries over into our appearances and explains why more women than ever are rocking messy top knots and buns than ever before.


FHI’s rounded edge allows you to easily curl or add waves without much effort. It’s almost as small as a travel flat iron, and I love that it straightens even the poofiest sections with just a single pass. But don’t just take my word for it, listen to Beyoncé (via InStyle): “I’m crazy about it! I can’t live without my flatiron! It takes me about an hour to do my hair, and the only time I don’t is when I’m on vacation.”
The titanium plates in the BaByliss Pro Nano Titanium Straightening Iron were designed to conduct high levels of heat (again, up to 450° F!) in a short amount of time. Coupled with the Nanotechnology that is packed in each plate, this hair straightener is ideal for anyone that experiences unwanted frizz or static on a regular basis! The titanium also acts as a barrier from corrosion keeping your hair straightener and precious strands free of build-up for years to come!
Not sure which temperature setting is right for your hair? We recommend starting slow and building up to higher heat settings gradually. Not only will you be able to perfectly identify the optimal heat setting for your hair, but you will also avoid overheating. After all, very few of us actually need upwards of 400° F to see the salon results we’ve always wanted!
The BaByliss Pro Nano Titanium Straightening Iron really is the Baskin Robins of hair straighteners, making it the perfect choice for anyone that wants to straighten their hair quickly. Whether you have naturally short hair and opt for extensions on occasion or you just chopped off your do’ into a new pixie cut, you will have a hard time not finding the perfect heat setting for your hair so many choices!
While temperature control is typically a good thing to have in a hair straightener, it can also result in hair damage if you're keeping the temperature too high. The GHD Gold eliminates the chance of any user error, operating at an even 365 degrees Fahrenheit. This is the optimal temperature for most hair types, getting you smooth results without damaging your hair. The gold coated ceramic plates heat up quickly and maintain an even temperature, eliminating the chance for any hair damaging hot spots as well.

By-and-large, most people with natural hair have some variation of type 3 or type 4 – which is exactly why low-end hair straighteners can be so dangerous. More curly natural black hair has a tendency to be more porous than other hair types. As a result, it can lose moisture easily and become damaged. With the wrong flat iron, this can lead to split ends and breakage after just a single use.

For those with thick hair, the idea of "quick styling" often feels like an impossible dream. It's usually easier to use the "throw it up and go" technique to get out the door in time. However, straight, sleek hair doesn't have to be a luxury reserved for those with fine hair, especially when you have a styling tool designed to tackle even the thickest, curliest hair like the Xtava Pro.
If you have trouble remembering to unplug your flat iron before heading out, you’ll appreciate the Chi Air’s one-hour automatic shutoff. Since people have preferences regarding auto shutoff this wasn’t a criteria for us, but our testers thought it was helpful. One tester said she often leaves her flat iron on in the morning and invested in a timed switch to make sure it’s off. So if you’re forgetful when it comes to turning off your tools, then auto shutoff might be an important feature for you.
According to hair pro Christian Wood, if you want to make sure your hair stays in the place, use the GHD gold mini styler. “I prefer a small straightener that I can get really close to the roots to remove stubborn kinks and cow licks,” says Wood. The small straightener trick is probably how he nails the beauty looks of Tessa Thompson, Emily Ratajkowski, Rosie Huntington, and Olivia Munn.
For some people, automatic shutoff is a critical feature since forgetting to unplug your flat iron could lead to a fire. However, others aren’t fans of auto shutoff since that means their flat irons could turn off while they’re still styling their hair. If this is the case for you, we recommend investing in a timed switch. That way, you can program the switch to turn off at a specific time and your flat iron will shut off as well.

An upgrade from their since discontinued Eclipse Styler, you won't be tempted to heat this flatiron up to 450 degrees, because the temperature dial is always stuck on one number: 365 (the ideal heat to mold hair without frying it, according to the scientists at GHD). Underneath each of those 365-degree plates are three fancy sensors that measure the density of the hair in the iron so that it can maintain consistent heat regardless of the chunk of hair you grab. The result? Silky, shiny hair with zero frizz.
