Hair health depends on several factors, and among them, taking care with the right products and treatments plays an important role. The risk factors that undermine its maintenance are many, but there is one that boasts the reputation of being the most insidious: the heat! Protecting our hair from any source of heat is a gesture of love and care that repays us by giving our hair health and beauty. But how can we do that? In this article, you will learn how following some useful tips, you can significantly reduce heat damage.

Listen to your body is the first step to take if you want to preserve your overall wellbeing, and giving yourself an extra cuddle, such as the use of new devices, cannot do anything but good!

Hair vs Heat Damage 1–0

Here are 3 tips to follow if you want to win this match:

1. Apply sunscreen protection on your hair

The sun is an important source of energy and wellbeing, but at the same time, it can cause a lot of damage to our skin, especially in summer. You should protect not only your skin but also your hair from the sun: excessive exposure to UV rays dries and weakens the hair, and over time burns and breaks it. Besides, UV rays bleach dye color molecules and melanin pigments, as a result, our hair becomes lighter in summer, and damages the keratin protein. To not run these risks, you can wear hats or stay under your umbrella at the beach, but avoiding sun rays is not possible. Fortunately, you can protect your hair and scalp using a sunscreen cream/oil/spray containing UV filters that create a protective barrier.

2. Use the hairdryer and irons properly

The heat source not only comes from the sun but also from hairdryers and irons, such as flat irons and curling irons, which we use almost every day. They are necessary to achieve our desired look, so it’s not that simple doing without them. It is thought that using them at high temperatures allows us to achieve much more results from the point of view of styling. It’s true, but not safe: using the hairdryers and irons at high heat temperatures damages the hair cuticle. To minimize the chances of heat damage, it’s recommended to use these tools at low temperatures. In addition to this, using them not that often allows you not to put your hair to the test. Regarding the hairdryer, you should hold it further away from your hair, so as not to be too close, or use the professional one with the intelligent control system of heat.

3. Use a Thermo-protector

Speaking of the damage that can cause the stylist tools, in addition to what is mentioned above, there is another way to prevent their hair damage: the use of a thermo-protector. It is like an invisible shield, providing protection and, at the same time, maintaining the health and beauty of your hair. Its usage is changing and revolutionizing the hair health panorama these days thanks to its effective benefits:

  • Heat Protection: it protects your hair from heat damage from styling tools by keeping hair cuticle integrity and health;
  • Anti-frizz effect: its barrier defends hair against heat and moisture as well, reducing frizz effects and ensuring softness and brilliance;
  • Hydration: some thermo-protectors are composed of moisturizing ingredients that help prevent dryness and split ends.

There are different types of thermo-protectors on the market, but the most common are in spray. It’s recommended to apply them on wet hair after washing and before styling, or on dry hair before using an iron. Using them makes the difference!

In conclusion, heat damage can compromise hair health, and what we can do is find a way to minimize its consequences. If you incorporate the three pieces of advice discussed above into your routine, you will not only provide effective protection but also achieve a perfect hair look!
