The temperature can be set in three stages between 180 and 210 degrees Celsius. Normal, thick, and robust hair can therefore be styled with the straightening iron without any problems.

FAQs on Best Hair Straighteners

1. What should be considered when buying a hair straightener?

The heating plates: The size of the heating plates depends on your needs and the length of your hair. For long hair, wide plates are more recommended than for short hair. However, if you also want to style curls with the straightening iron, then you have to use small heating plates.

The temperature setting: Most straightening irons have an adjustable temperature setting. Depending on which hair type you have, you should pay attention to the right temperature setting when buying.

The cable: A rotating cable enables better handling and adapts better to the movements. The detail is particularly helpful when used to style waves or curls. The cable length should be at least two meters.

The heating-up speed: good straightening irons are ready for use in 15 to 30 seconds. Teflon heats up the fastest and titanium, for example, takes a little longer.

The automatic switch-off: An automatic switch-off function should be integrated in every straightening iron. As a rule, the straightening irons switch off by themselves after 30 to 60 minutes.

The accessories: A fireproof case and a heat protection pad are available on some models and ensure more safety.

2. What temperature is suitable for which hair type?

When straightening your hair, heat is the most important factor. Some straighteners have a set temperature. In most models, however, the heat can be regulated. The most suitable temperature for your hair depends on your hair structure. We have compiled the recommended settings for you here:

100 ° C to 140 ° C – for very sensitive hair.
140 ° C to 160 ° C – for fine and thin hair.
160 ° C to 180 ° C – for normal hair.
180 ° C to 240 ° C – for thick and unruly hair.

3. Which coating is gentle on the hair?

The surface of the heating plate is one of the most important features of the straightening irons. Models with a ceramic coating are the most common and suitable for all hair types. The smooth plates do not damage the hair and allow even heat distribution and a short heating time.

Tourmaline straighteners provide the hair with moisture and shine. They are suitable for fine and sensitive hair as they prevent unwanted creping and static charging at the same time. Less common materials are titanium and Teflon. However, they are just as effective at protecting against heat and are often found on professional styling tools.

4. Which straightening iron technologies are out there?

Two technologies are common in home straightening irons: Ionization and steam technology. In straightening irons with ion technology, negatively charged anions are transferred from the straightener to the hair and positively charged cations are neutralized.

The anions act to hold the moisture in the hair cuticles. This will make you look shinier and healthier. The method also protects the hair from static electricity.

The steam technology is rather unknown, but it is very suitable for unruly, dry, and thick hair and enables quick and gentle styling. The models are less suitable for fine hair.

5. What are the different heating plates used in hair straighteners?

The size of the heating plates is also differentiated. Narrow heating plates are ideal for short hair. You can also use them to create curls so that you do not need an additional curling iron. The classic plate size is around 25 millimeters. You are most flexible with this heating plate, as the straightening iron is suitable for almost all hair types and lengths.

Wide heating plates, on the other hand, are particularly suitable for long and thick hair. Smoothing is faster and much easier thanks to the wide plates. However, curls can be difficult to create with wide devices.
