A lot of hair straighteners will boast that their nano-ceramic like this is a good thing. In reality, this means that they’re made up of a cheap filler material (that will not heat as evenly or remain as durable as true ceramic) which is coated with a thing outer ceramic layer. If you want a flat iron that’s safe for natural hair, make sure you go 100% ceramic, or better yet, solid ceramic infused with tourmaline or titanium.
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.
If being limited to only a handful of temperature settings isn’t really your cup of tea, look no further than the BaByliss Pro Nano Titanium Straightening Iron! This lightweight flat iron features a whopping 50 heat settings for hair types of all shapes, styles, textures, and colors making it one of the most versatile hair straighteners on our list.

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.
