Flat Iron For Thick Hair-Buying Guide

Usually, the temperature needs to be set between 350-400°F.
- Right plates
Ceramic: Less damaging to the hair. Heats up from the inside.
Titanium: Heats up faster, and the outside heats up first.
- Plate size for thick hair
Choose a plate that is wide and can hold more hair if you have thick hair.
- Technology:
Make sure that the technology used to design the straightener is one that allows heat to be distributed evenly.
- Temperature Range:
Ensure the straightener has many temperature controls and can be adjusted for preference.
Other factors that you must consider:
- Grip: Ensure the iron is easy to hold onto and will not slip.
- Weight: Should not be uncomfortably heavy and as lightweight as possible, so it is easy to carry around.
- Auto turn-off: Must have this feature, wherein it shuts off automatically if not used for a while.
What Safety Features Should A Flat Iron Have?

The Bottom Line
Thick hair appears voluminous and makes you look like a diva. But it also requires special styling tools and hair care products to stay healthy and damage-free.

In addition, these flat irons help retain moisture and minimize frizz.
