How to choose a professional hair straightener that does not damage your hair?

Before moving on to selecting the three best models, it is essential to review in a brief guide the fundamental elements that must be included in a straightener so that it protects your hair as much as possible.

100% ceramic or titanium plates

To protect the health of your hair, the material your plates are made of is essential. The best materials are titanium or ceramic. And ideally, if your budget allows, the leaves should be 100% titanium or ceramic.

Suppose the straightener you choose has only a light layer or coating of ceramic or titanium, but the inside is made of another material (e.g., aluminum). In that case, your hair may come in contact with these internal metals and be damaged during use.

We know this is one of the most expensive aspects of the product, but you also have to consider that the device’s quality and lifespan will be much higher.

humidity sensor

Some models also incorporate humidity sensors that detect when your hair is too wet to straighten.

The cuticle (the outer part of your hair) burns more quickly when damp. This sensor is not an essential element, but it is true that sometimes in a rush, we do not put much effort into drying, and we can damage our hair if we use the straightener when our hair is still damp.

This is why a straightener equipped with a humidity sensor will let you know when your hair is dehydrated and ready to be straightened or curled.

Adjustable temperature

Another critical aspect is that the model you choose must allow you to adjust the temperature according to the characteristics of your hair. This result is obtained thanks to the sensors integrated into these straighteners, which constantly measure the temperature of the plates.

For excellent safety, it is advisable to equip them with a temperature indicator so that you know the amount of heat you are applying to your hair.

As stated in this post, too high a temperature can damage our hair. For this reason, we recommend that you always apply the minimum temperature that allows you to obtain the best results without carrying out too many passes.

After reviewing the essential elements that a straightener must have to avoid damaging your hair, below, you will find a selection of three straighteners that meet these requirements.

Comparison of the best straighteners that do not damage the hair

1- GHD Platinum+ Styler – 1″ Flat Iron, Professional Hair Straightener

GHD PLATINUM PLUS: Ideal for colored and fragile hair

The GHD Platinum Plus is the most respectful and attentive to the color of highlights and dyes, preventing damage and discoloration thanks to its temperature control technology and extreme care.

Its ultra-zone technology predicts and adapts to the needs of your hair. How does it work? Each of its plates incorporates an “infinite” sensor that controls the container’s heat 250 times per second always to maintain them at 185º C regardless of the hair’s thickness, the styling’s speed, and the lock’s size.

The other unique feature of this model is that it has a patented plate design that ensures perfect alignment of the plates to provide better control during styling and ensure ideal glide. Although it does not have a humidity sensor, it is a 100% recommendable styler with only one drawback: its high price, which will make you wonder if the investment is worth it.

On the other hand, these hair straighteners last a very long time (some users have had straighteners from this brand for more than ten years in perfect condition). So if you spread the cost over the years of the estimated term, it’s easier to be convinced of the investment.


  • Ultra-zone predictive technology.
  •  Long rotating cable.
  •  The constant optimal temperature of 185º C.
  •  Versatile: smooth and loop (rounded edges).


  • Price.
  •  Does not include a humidity sensor.

2- Corioliss C3 Hair Straightener Flat Iron Professional for Hair Titanium Plates 

Corioliss C3: For perfect temperature control

The Corioliss C3 is part of what we consider to be high-end models. Its plates are one of the few made of polished solid titanium, which is even more robust and durable than ceramic.

It incorporates negative ion technology to prevent static electricity. This improvement in the frizziness of your hair will help you achieve a more professional result and reduce the number of passes, which is also a positive aspect of its protection and maintenance.

It also features tilting plates with an excellent tip (which allows you to hold them by the end without getting burned) and rounded edges, which are great for curls and waves.

As the benefits listed above needed more, it’s temperature adjustable and comes with a heat-resistant storage pouch.

The main drawback, as it could not be otherwise with all these features, is that it is somewhat expensive.


  • Solid titanium plates.
  •  Adjustable temperature from 135° to 235° C.
  •  Anti-frizz technology with negative ions.
  •  Heat-resistant storage case.


  • Price.
  •  They do not have a security lock.

3- Braun ST300 Satin Hair 3 Style and Go Straightener

Braun Satin Hair: A cheap straightener that protects hair

Braun isn’t the brand most people have in mind when it comes to straightening hair. But their Satin Hair model is one of the best around. Their 100% ceramic plates will leave your hair shiny and smooth and prevent damage thanks to their quality and even heat distribution.

It has everything you need from a professional straightener to create multiple looks: rounded edges, tilting plates, a cold tip, and a swivel cord.

As a bonus, it incorporates technology that allows you to set up three different profiles – ideal if you share with colleagues or family members. The straightener automatically adapts the temperature settings to your characteristics throughout the styling process, depending on your hair type, humidity at any given time, etc.

It is a straightener whose price is quite economical on the high end. On the other hand, it is a pity that the cord is not a little longer. It also doesn’t come with a safety lock or a heat-resistant cover for storage.


  • 100% ceramic plates.
  •  Programming according to the user’s profile or hairstyle.
  •  Temperature and humidity sensor.
  •  Tilting plates and rounded edges.
  •  Cheap


  • No security lock.
  •  Short cable (2m).

What is the difference between a traditional straightener and a steam straightener?

The steam straightener straightens the hair using steam, gentler on the hair cuticles. The only difference is that steam straighteners minimize frizz and leave hair softer. It is because they retain the proper amount of moisture. On the other hand, they contain a built-in reservoir that you need to replace with water regularly and are primarily intended for straight styling.

Should we prefer a small hair straightener to a straightener with larger blades?

Again, it depends on your needs. The small straightener is more controllable and more convenient to use, but if you have long hair, a broad plate straightener may be better. It allows you to process more hair at once and saves time. The only basic guideline is that wide plate straightener are not recommended for people with short hair; everything else is up to you.
