Our advice and questions

– What sizes of plates?
The choice of the plate size will depend on the nature of your hair. The long and rather thin plates are for normal, fine, short or medium-length hair and the wide plates are suitable for hair that is more difficult to style, very long, frizzy or frizzy.

– What temperature ?
Here too, the temperature of your straightener must be selected according to your hair type. Because even if it is true that the higher the temperature, the faster the straightening, this high power is not recommended for the finest hair which will risk being damaged.
Here are the temperatures that we recommend according to your type of hair: Very damaged hair: 80 ° to 140 ° C
Fine hair: 140 ° to 170 ° C
Normal hair: 170 ° to 190 ° C
Wavy hair: 190 ° to 210 ° C
Thick hair: 190 ° to 235 ° C
But there are also straighteners capable of automatically adapting their temperature according to the type of hair to be straightened.

– Which coating to choose?
The material of the plates is an important consideration when choosing your straightener. The three most common coatings are ceramic, titanium, and tourmaline. The ceramic facilitates gliding and the diffusion of heat. It is ideal for fine hair for a silky and shiny result. Titanium is a light material that offers effective straightening, but will not be suitable for hair weakened by colorations and discolorations. Finally, tourmaline, which is a semi-precious stone, is the ideal coating for frizzy hair, because it will limit static electricity and frizz.

What are the differences between a classic straightener and a steam straightener?

In addition to its main function which is to straighten the hair, the first difference that can be seen on a steam straightener is its format which will be more voluminous than a traditional straightener. Due to its steam function, the device is composed of a tank which must be filled with demineralized water before each use.
Its advantage is to release steam in order to prepare your hair before the passage of the plates. This protects your hair from heat damage. If you have thin and / or sensitized hair, a steam straightener is the most suitable device.

– Use your straightening iron correctly
Once you have selected your ideal hair straightener according to the various characteristics mentioned above, it is now important to know how to use your heating device properly.
If you straighten your hair after washing it, take the time to dry it well. Running your iron on hair that is still damp is the best way to damage it, and in the worst case, dehydrate the hair fiber and make it brittle.
Last thing, do not iron the same wick ten times, at the risk of seeing your lengths cry out for help!

– Protect your hair with a specific product before straightening
The step not to be neglected is undoubtedly the application of a spray thermo-protector before passing the straightener. It acts as a protective heat barrier and also simplifies the gliding of the device.

– Apply a moisturizer after smoothing
In the same way as we apply a treatment before, it will be advisable to apply another one after! Indeed, to finalize your smoothing and especially hydrate your lengths after the passage of heat, opt for an oil or a cream that you will apply lightly and evenly over the lengths.

A smoothing that lasts is above all a smoothing that has been done carefully. Take your time by separating your hair into different sections and smoothing strand by strand.
Once the smoothing is finished, you take your hair dryer again and put it in cold mode and run it for a few seconds, always positioning the air flow downwards in the direction of the lengths. This little trick allows you to fix the hairstyle.
You can also put the odds in your favor by opting for a smoothing shampoo and conditioner.
Finally, to keep it smooth after a night's sleep, always brush your hair before going to bed and tie it into a low ponytail with an elastic that doesn't leave a mark.
There is also an ancestral method which consists of winding its lengths in a strip of fabric called the Kardoune.
