What to Consider?
Here’s what you should look out for in a flat iron before buying
Always ensure that whatever flat iron you intend to get has temperature control. You don’t want to just ‘freestyle’ the heat level, because that could damage your extensions. This is especially important for synthetic extensions because human hair extensions can still withstand some degree of heat.
Also, note the material used for the flat iron. Materials like titanium or ceramic are excellent because they conduct electricity well, and won’t heat up outside the surface. However, those made with metal on the interior and exterior may always radiate heat on the outside, and that could be uncomfortable.
Automatic Shut-offs or Regulator
This feature in flat irons will enable its durability. Flat irons with automatic shut-offs have a way of detecting when the iron is in use or not. So even when you’re carried away with after-styling paparazzi, the flat iron automatically puts itself off. This enables longevity.
Here are some commonly asked questions relating to flat irons for hair extensions and their quick answers.
