Thermal protector: how can the product save the health of the wires?

It is very common to use flat iron, dryers and babyliss on the hair, but did you know that excess heat can damage the hair? Well, these allies can become great villains when it comes to hair health.

Thus, the use of thermal protector is the number 1 rule to keep the wires protected from external aggressions, including excessive heat.

With it, the wire is protected by means of a film, with a sealing action that prevents water and nutrients from being lost during the receiving of heat.

There are several types of thermal protectors, which can be used on damp or dry hair. They can increase the durability of the straight or curls, decrease the frizz, keep the wires aligned, among other proposals.

However, it is important to note that even with the use of the thermal protector, heat equipment can only come into contact with dry locks!

The Healthy Minute separated some tips on how to use the product correctly and keep your hair healthy and silky daily.

What is the thermal protector and how does it work?

The thermal protector is a product developed for all types of hair. It assists in protecting against the high temperatures of the dryer, flat iron and babyliss.

When using any heat source, water evaporation from the hair occurs very quickly and not only does the hydration go away, but also the hair nutrients.

This aggression results in the formation of bubbles in the structure of the threads, leaving the locks more dry and very fragile.

Thus, the thermal protector forms a protective layer on the hair, sealing the strands and preventing the loss of water and nutrients during the use of heat sources. At this stage, the locks are protected and free from dryness.

In addition to thermal protection, the product may contain other benefits for the hair, such as assisting in hydration, reducing frizz, increasing the durability of straight or curls, keeping the locks aligned and returning the shine.

When to use?

There is no frequency indicated for the application of the product, but the ideal is to apply it every time you use a heat source such as the flat iron, the babyliss and the dryer.

The thermal protector helps in the drying process of the wires, reducing the time that the dryer or other instrument needs to stay in contact with the hair, in addition to protecting the locks from daily external aggressions.

How to use the thermal protector?

The ideal is to gently remove excess water from the strands with a towel or wait for the hair to dry naturally for a while before applying the product.

At the time of application – if the product is in cream, it is recommended to put a small amount of the product in the palm of your hands, equivalent to a coin of R $ 0.50 cents and apply lightly throughout the hair. You can use a comb or brush to distribute the entire thermal protector over the hair fiber.

In spray versions, it is recommended to spray the product all over the hair and use your fingers or a comb to spread the product evenly over the strands.

It is important to mention that the excess of thermal protector can cause a rebound effect, leaving the threads with a heavy and oily appearance. The best is to use a small amount and choose the one most suitable for your type of hair.

How to use thermal protector before flat iron

If you choose to let your hair dry naturally and decide to finish your hairstyle with the flat iron or babyliss, the ideal is to use lighter thermal protectors, such as a serum or spray.

The application is basically the same: if it is spray, just spray the product all over the hair and spread it with your fingers or a comb for complete protection of the strands.

If it is the protector in the form of a serum, it is recommended to put a small amount of the product in your hands and start spreading from the length to the ends so as not to weigh.

After application, it is recommended to look at the product packaging to see how many degrees the protection is on the wires. Thus, it is easier to adjust the heat source to the indicated temperature, preventing the hair from being unprotected.

What is the difference between thermal protector and leave-in?

Leave-in is a finishing treatment to be applied to clean hair. This type of product has several purposes that meet various types of needs and hair.

Its functions are varied, being able to be moisturizing, texturizing, antifrizz, among others.

However, not all leave-in is thermal protector! It is important to always look at the product proposals and check the benefits or the list of ingredients to make sure it will protect the strands from high temperatures.

Today, most products, in addition to being leave-in, which finishes and maintains the health of the hair, also protects against high temperatures, being more comfortable and avoiding the need to buy two different products.

Regarding the application, the two products can be used equally. Both in wet and dry threads, which can give more finishing and definition in the threads and, if there is thermal protection, also protecting it from excessive heat.
