Buyer’s Guide to Select the Best Flat Iron for Thick Hair
1. Heat Settings
Thick hair usually requires high heat for straightening; therefore it is important to look for a Flat iron that offers a high heat setting.
The optimum temperature for straightening thick hair is 365 F, so always choose a Flat iron that heats up to at least 365 F and up to 450 F.
It is generally recommended that you do not go over the same section of hair again and again, and that is why it is important to have a high heat setting so that you do not damage your hair.
2. The material of the Plates
Flat iron plates can be made up of different types of materials, the most common materials are ceramic and titanium. The plates could be made either from one of these materials or from a mixture of both.
These materials are great for thick hair, as they are capable of holding high heat, and they allow the heat to distribute evenly, which ensures that the hair is not damaged in the process.
Ceramic or titanium plates glide through the hair without any resistance, which greatly reduces heat damage. Another material that is often used is tourmaline; it is a kind of mineral stone that is infused into ceramic to produce negative ions, which is great for reducing frizziness in thick hair.
3. Size of the Plates
The size of the straightener determines the amount of hair that can go through the two plates in one pass. For thick hair, we obviously want a larger plate, so that more hair can be straightened at once.
The plates must be wide in order to ensure that all the hair strands get equal amounts of heat and get straightened effectively. The minimum plate size that one should look for is 1inch and the maximum is 1.75inch.
