The Braun Satin Hair Straightener does what it is supposed to - it straightens the hair. However, thicker hair has to be crossed over the strand several times, otherwise the result will be unsatisfactory. Thanks to the IONTEC technology, this product offers more protection and moisture for the hair at the same time. It is suitable for all hair types (especially thinner hair) and can be adjusted manually. The price/performance ratio is therefore completely ok.


  • Detailed operating instructions
  • Easy to use
  • Better styling protection thanks to IONTEC
  • Can also style curls and waves


  • Not so well suited for thicker hair with Frizz
  • The additional warranty document is only available in Turkish.
  • Very short cable

Good hair straightener, useful for thin hair.

The product

The Braun Satin Hair Straightener comes in a rather small package. The packaging itself is printed with information of the product in different languages. The first impression of the quality is good. It feels very stable, whereby the plates are easily movable to the left and right when pressed together. The smoothing iron has a display, an on/off button, as well as a "-" and a "+" button to set the temperature. There is also a satin ion button. This button provides additional protection for the hair by restoring the moisture content of the hair, which is otherwise often damaged by styling at too high temperatures. If you press this button, you will hear a soft noise, which is "normal" in this case.


To use the smoothing iron, first connect it to a power cord and press the On/Off button for a few seconds before it starts. The LCD indicator will turn red during heating. Depending on the type of hair, the following temperature setting is recommended:

1. fine, porous, dyed, blond hair -> 130 °C - 160 °C

2. normal hair -> 160 °C - 175 °C

3. strong, resistant hair ->175 °C - 175 °C

4. for professional styling -> 175 °C - 200 °C

With the "-" or "+" key you can set any temperature. Then the thermometer symbol flashes until the desired temperature is reached (approx. 30 seconds).

When using it, it is important to use only small hair strands. With this device it is noticeable that with thicker hair one must cross over the hair strand several times in order to achieve an optimal result. Otherwise the handling is very easy and the device lies comfortably in the hand.

In addition to smoothing, you can also make light waves with this hair straightener. To do this, you have to twist the hair strands a little at the end with the help of the hair straightener.

An additional function of this product is that it remembers the last temperature setting for the next use.

This device has an automatic switch-off function, i.e. it switches itself off automatically after approx. 30 minutes.

How do you like this product?


Sometimes when I use the ST710, there is a red indicator light with three waves, do u know what is that supposed to be?
The heat can be changed in small steps by pressing a button and allows individual use. An LED display indicates the level of the hairdryer. However, the lights are not separated from each other and you can not read the exact level. The air flow can also be adjusted manually in two stages.
How long do straight hairs last?
Until the next time the hair is washed.
How does the product work with natural curls?
It makes the hair smooth even with natural curls.
How wide are the ceramic plates?
Approx. 2 x 6 cm
Is a heat-resistant bag included in the scope of delivery?
No, unfortunately not, but the trowel cools down very quickly.
