You do not have to use a blow dryer. In fact, I recommend not using one at all, as it could save extra damage to your hair and the extra heat isn't needed. After a shower, you could put your damp hair in a braid, let it dry in the braid, and when you want to straighten, your hair won't be as puffy or frizzy. That ultimately leads to straight, sleek hair.
This styling iron has 1-inch plates, allowing it to do more than just straighten. It can also curl, flip, and be used to add volume if your hair tends to fall flat. It heats up in under 30 seconds so you can start styling almost right away, and there are a wide range of temperature settings from 250 degrees to 460 degrees Fahrenheit. While the high-temperature options make this straightener ideal for other hair types, too, if you do have fine hair you'll want to keep this in the lower temperature range.
The nano ceramic plates in this straightener deliver far-infrared heat, a gentler alternative in and of itself. As if that weren't enough, there's also a reservoir where you can pour in some of the (included) argan treatment and thermal protectant, creating a conditioning steam that will strengthen and safeguard strands while you straighten. Admittedly an extra step, sure, but one that's well worth it.
