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.

“I bought the HSI titanium tourmaline ionic flat iron and I was so impressed with it. It glides so smoothly down the hair without any tugs! The digital display screen lets me adjust the temperature without any problems, it heats up fast, and I love that it comes with a pretty purple pouch, glove, and argan-oil serum. I also own the digital HSI ceramic ionic flat iron from 2013, and it’s still going strong, but I do like the titanium iron better, and I see myself using for it for years to come. It leaves my hair shiny and soft!”

Available with either ceramic plates (good for all hair types) or titanium ones (choice for curly, thick, and coarse textures), this innovative styler features touch sensor technology that lowers the heat when it's not being used, then automatically brings it back up to temp as soon as it's touched. Translation: No more waiting for your iron to heat up in between passes. Use it for smooth and sleek styles, or take advantage of the round brush-esque attachments to create more of a bouncy blowout effect.
