The plate material you choose can also make a big difference on your style results. Ceramic, titanium, and tourmaline are the most common terms you'll come across. Ceramic plates hold heat well and provide even heat distribution, preventing any hot spots on the plates can cause damage. Ceramic is especially effective for fine hair that can be especially vulnerable to heat damage. While many hair straighteners have ceramic coated plates, plates made entirely from this material are more effective, as this coating can wear off over time. Tourmaline is a gemstone, but when crushed and used to coat the plates of a hair straightener, it has properties and results similar to ceramic plates.
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.
Despite these downsides, the HSI Professional comes with plenty of positives, including extras not often found with other hair straighteners. Along with the straightener, you'll receive a carrying case, a heat-resistant glove for easier hair styling, a style guide, and a travel-size argan oil leave-in hair treatment serum to smooth and protect your hair. This is more than most high-end hair straighteners come with, all for a fraction of the price.
Straightening irons, straighteners, or flat irons work by breaking down the positive hydrogen bonds found in the hair's cortex, which cause hair to open, bend and become curly. Once the bonds are broken, hair is prevented from holding its original, natural form, though the hydrogen bonds can re-form if exposed to moisture. Straightening irons use mainly ceramic material for their plates. Low-end straighteners use a single layer of ceramic coating on the plates, whereas high-end straighteners use multiple layers or even 100% ceramic material. Some straightening irons are fitted with an automatic shut off feature to prevent fire accidents.
The ceramic blue plates aren't just pretty; they push conditioners into the hair, quelling frizz 65 percent more efficiently than a traditional ceramic iron. Even experts were impressed. "[It] leaks heat-protective ingredients onto the hair at the exact point of contact, coating every strand during the straightening process," says cosmetic chemist Ni'Kita Wilson.
