No, it is not always necessary to use the highest temperature, depending on the curvature of the wire, it can change
While your instincts may be to jump to the highest temperature when you take the iron, this isn’t always necessary and it’s important to combat that urge. “All equipment that reaches very high temperatures can damage the hair cuticle (the external structure) and, in this way, make the hair more porous, often also fragile” he warns Meire Gonzagadermatologist.

If you’re not sure which temperature setting to choose, you’re not alone. Depending on your hair type and goals, a lower setting can actually create the best and healthiest result for you.
THE IDEAL TEMPERATURE FOR EVERY TYPE OF HAIR
According to Meire, each curl requires a different temperature and reinforces the importance of not exceeding it. “Never exceed that temperature, especially when you use it at home because the possibility of damaging the wire is very high and, of course, never forget to apply the heat protector when using this type of appliance”.
- Very fine straight hair or delicate hair: 150 degrees
- Wavy and curly hair: 180 degrees
- Curly or thick hair: 190 or 200 degrees
HOW TO PREPARE THE HAIR FOR THE HAIR
the dermatologist Natascia Crepaldi explains that “applying the heat protector to the hair before using the straightener helps to reduce the damage that could be caused by its use by up to 50%. Another tip is to use the straightener only with dry hair”.
AND THEN?
You may not even think about it too much, but the first wash after using the iron is very important. “The ideal is that we do a hydration, to recover the hair cuticle“says Meir.
