What Makes Brilliance New York Advanced Professional Diamond Flat Iron the Best
Technology is what sets this advanced professional flat iron apart from others is also what makes it one of the best hair straighteners. Firstly, Brilliance New York uses 100% titanium plates for this model, featuring the latest diamond technology. Not all brands include the coating of crushed diamonds over the plates like you get with this flat iron.
Specifically, the Advanced Professional Diamond Flat Iron comes with a set of two ultra smooth Diamond and titanium plates. The Diamond plates with crushed diamonds over titanium offer many daily styling benefits. For example, this design enables a very high maximum heat temperature to deliver straight hair in less time than many traditional fully ceramic-plated models.
This 1 in styling tool can reach an impressive top temperature of 450 degrees Fahrenheit (225 degrees Celsius). That’s least 50 degrees Fahrenheit more than some other hair straighteners.
The high heat enables you to control your hair well, indicate users’ reviews. And getting it to the straightness you prefer rather than spending valuable time only to still have kinks in your hair is a good thing!
Brilliance New York’s Safety Conscious Design
Given the high heat, this flat iron can reach, we are pleased that Brilliance New York designs it with safety features. For example, it automatically shuts off to prevent a potential accident like a fire if left unattended. When you’re in a morning rush, that setting is terrific to have so that you’re not sitting at work wondering if you turned off the appliance or not.
Even if you didn’t do so, it’s made to turn itself off you forgot to do so. Furthermore, the tip stays cools as you use it for safety and ease of use, no matter the current temperature.
Also, if you worry that this Professional Diamond flat iron will be overly hot and fry your hair, that’s not a concern with the great precision the user has at controlling its heat level. In fact, this styling aid has over 100 temperature settings available to you.
Simply adjust the built-in LCD display to the desired temperature. Not only does this very flexible functionality enable you to set the hotness level exactly where you’re comfortable but it also allows you the best one for your particular hair.
Course hair, for instance, typically requires higher heat than the normal hair type to straighten it. For fine or damaged hair, try a cooler setting to safeguard against possible damage to the tresses.

How Did We Choose the Top Hair Straightener as the Advanced Professional Diamond?
The perks we’ve discussed so far aren’t ones you’ll get with every titanium or ceramic flat iron, by the way. That’s a huge part of why this Brilliance New York model is on the top of our list.
The other reason the Professional Diamond Flat Iron is our #1 choice is that it’s professional grade. So, what does that mean, exactly?
It provides salon-worthy styling without having to go to the salon, which can be expensive to do regularly. Alternatively, this appliance is one that Brilliance New York designs for use by salons, and it’s even approved for Brazilian Keratin straightening services. All of which indicates to us that this particular flat iron is high quality.
While that means paying more than most ceramic hair straighteners, we feel it’s worth it for the exceptional temperature levels and all-over heat, neither of which typically comes with cheaper models. The equal heat distribution, thanks to a smart design that includes far-infrared heat, means you won’t have to pass the tool over your hair as much as one with uneven heat, thus saving you time and energy.
What’s more, uneven heating leads to hot spots, which can tug or pull the hair; the Advanced Professional Diamond flat iron prevents this damage issue with a built-in Advanced Ceramic Heater for better recovery time. The all-over heat comes quickly too; fast heat means fast styling time in a busy day, thankfully.
Another reason it’s worthy of the price tag is the included lifetime warranty. Rather than going through cheaper hair straighteners that don’t last, you’ll actually save money over time by only buying the one tool. One reviewer online boasts she’s had hers for 10 years, while another one writes she’s in her 5th year of use.
Additional Features of the Brilliance NY Advanced Professional Diamond Flat Iron
If you often travel, whether it’s for pleasure or work-related, you’ll likely appreciate something else: the dual voltage design. This immediately means that when you travel to another country that has different wall plugs than the U.S. – yes, that’s real – you’ll be able to use this styling appliance.
That’s good news when you want to look your best while away from home. Simply put it into your luggage and use it at the hotel or another place.
Lastly, an ionic generator is part of the styling tool design. Specifically, it has not only millions but hundreds of millions of negative ions more than some other hair straighteners. While that might not seem important, it’s actually key to getting shiny hair without frizz.
Basically, the negative ions contribute to a smooth cuticle layer, hence no frizz and luminous-looking locks. A related benefit is that ionic flat irons, including the Brilliance New York Diamond flat iron, work well at straightening a range of hair types, from fine to wavy or thick.

Conclusions on the Brilliance New York Advanced Professional Diamond Flat Iron
Although the Diamond flat iron is at the higher end of the typical hair straighteners’ price range, it’s anything but average. The results are professional looking, thanks to numerous thoughtful features, including a very high temperature maximum, ionic generator, precise control over hair, and a lifetime warranty.
These features and the others we note in the above review enable users to get high heat fast and evenly for salon quality strands, all while simultaneously providing excellent hair protection. Achieving straight shiny hair doesn’t have to be a myth with a tool like this! Thus, the Advanced Professional Diamond Flat Iron from Brilliance New York is a valuable addition to a home or a professional salon.
