Tips for Choosing the flat iron for keratin treatment

When you’re looking to purchase a flat iron for keratin treatments, there are a few factors you’ll want to keep in mind to ensure you’re purchasing the best flat iron for your needs. Some of the most important flat iron features to consider include the iron’s material, temperature range, and features.

Most flat irons are made with either titanium or ceramic material, both of which are very effective when it comes to straightening hair.

While both materials are effective, ceramic flat irons tend to be more popular because they’re less damaging to hair. Ceramic flat irons heat up and cool down more gradually than titanium flat irons, which means they won’t cause hair to get overly hot and burned. They also don’t transfer as much heat between passes, which helps to keep hair from becoming over-straightened.

Temperature range
The temperature range of your flat iron will play a major role in how effectively it straightens your hair. For best results, your flat iron should have a temperature range that is high enough to effectively straighten hair without causing damage, but low enough to avoid overheating and burning your hair.

Many flat irons have temperature ranges that range from around 300°F to 450°F. For the best results, you’ll typically want to choose a flat iron that has a temperature range that is at least 350°F.

As you search for the best flat iron for keratin treatments, you’ll come across a variety of different flat iron features. Some of the most important flat iron features to consider include the flat iron’s digital controls, tourmaline technology, and heat-resistant cases.

Digital controls
Many flat irons come with digital controls that make it easy to adjust the temperature of the flat iron. While digital controls are a helpful feature, it’s important to note that they’re not always reliable. In some cases, the controls may malfunction or provide incorrect temperature readings. Before purchasing a flat iron with digital controls, it’s a good idea to do some research to determine whether or not the controls are reliable.

Tourmaline technology
Tourmaline technology is a feature that’s often included in flat irons that are designed to straighten and smooth hair. Tourmaline technology uses crystals that contain both negative and positive charges, which creates an electric field that helps to smooth hair and prevent frizz.

Heat-resistant case
