How to Choose the Right Hair Straightener For Fine Curly Hair

Buying the right hair straightener according to your hair type is vital in ensuring the tool does not damage your hair and works effectively.
Here are a few factors to consider when choosing the best straightener for fine curly hair:


The shape of a flat iron directly affects its versatility. Rounded or curved plates and edges are easier to work with, and can easily make transition function from straightening to curling.
You can, therefore, make more use of the hair straightener if it’s curved or rounded at the edges and plates.

Plate Width

Depending on their function, the width of the plates is an essential factor to consider when buying a hair straightener.
Choosing the right width depends on the volume and texture of your hair. Women with smooth and fine hair may experience too much heating due to thick plates, and should, therefore, consider irons with narrow plates.

Plate Material

Often plates in hair straighteners can be made of either titanium, tourmaline, or ceramic irons. All three are good, but you need to choose one that is suitable for your hair type.
Titanium plates tend to heat more quickly, producing more heat. This is recommended for rough curly hair.
Tourmaline works well on fine, damaged hair since they produce negative ions, perfect for eliminating frizz.
Ceramic irons distribute heat more evenly, and are suitable for most hair types.


Not all hair types require extreme temperatures for straightening. In fact, the recommended temperature for fine hair is about 360 °F. You should consider the flat irons that have a limit around this figure or allow you to adjust temperatures.
At the same time, go for a hair straightener that distributes heat evenly throughout your hair. The ghd Gold Professional Hair Styler, in particular, has a heat sensor to protect your hair.

Straightening Tips for Fine Curly Hair

To achieve the perfect look using a flat iron, follow the following tips;
  • When washing your hair, use a microfiber material towel to prevent hair from frizzing.
  • Avoid blow-drying your hair. If you have to blow dry your hair, let the blow-dryer’s nozzle facing downwards.
  • Use boar bristle brushes to avoid static.
  • Use a thermal protectant to protect your hair while using a flat iron to straighten your hair.
  • Take note of the temperature readings on your flat iron before using it. Do not exceed 360 degrees.
  • Split the hair into small portions to avoid skipping or uneven distribution of heat.
  • Finishing products come in handy in reducing and eliminating frizz.
  • Use the latest flat iron, which incorporates modern technology to protect your hair.
  • Do not use a flat iron on wet or damp hair. First, dry it thoroughly using a good towel to prevent damage.

FAQ: Flat Irons For Fine Curly Hair

How Do Hair Straighteners Work?

The hair straightener’s resistors convert the electricity to heat energy. Auto sensors control the amount of energy released depending on the hair type and volume. You can reduce or increase the amount of heat on your flat iron.

Can You Use Hair Straighteners Every day?

Of course, you can use a hair straightener every day, but the effects are adverse. Extreme temperatures on your hair cause breakage due to drying and increase hair fragility; it is advisable to avoid using hair straighteners every day to maintain healthy hair.

Which is Better, a Tourmaline or Ceramic Hair Straightener?

Tourmaline works best with damaged hair since they produce a lot of negative ions, which reduce hair frizzing. Ceramic, on the other hand, works more efficiently to distribute heat evenly to your hair. However, due to this feature, they wear out more quickly.

What Heat Setting is Right for Fine Hair?

Temperatures around 250- 380 degrees are recommended for all hair types. However, depending on your hair types and volume, you can adjust the temperatures to suit your needs. In this case, fine hair requires about 360 degrees Fahrenheit.

How to Clean a Flat Iron

It is necessary to clean your flat iron regularly to enhance its effectiveness. To clean the tool, you need the following equipment:
  • Cotton.
  • Damp cloth.
  • Alcohol
  • Unplug the flat iron.
  • Use alcohol immersed cotton to clean the plates.
  • Wipe using the wet cloth.
  • For stubborn spots, you can use a toothbrush to scrape out the dirt gently.
