Japanese thermal protection for hair. Why is it needed and how does it

After contact with the hair, the product creates a thin film on the entire surface of each hair, preventing the hair from excessive moisture loss. Good heat protectants also heal and strengthen hair, make it manageable, prevent split ends, tangle problems, etc. It is very important how much thermal protection treats hair. Japanese thermal protection products stand out because they most intensively restore hair, while simultaneously performing the function of protection. 

It turns out that the bulk of thermal protection contains a mixture of silicones, ethyl alcohol, as well as additives that make silicones easier to wash out and produce a smell. Due to the controversy regarding the safety of silicones and the difficulty in washing them out of the hair, they began to develop new series of thermal protectants that are easily washed off even with mild shampoos. As part of such preparations, water-soluble polymer films are used instead of silicone, which take part of the temperature effect on themselves and significantly reduce hair damage. There are a lot of such polymers and different manufacturers can use different polymers in their compositions. In Japanese care products, emphasis is placed on naturalness, so you will not find pure silicones here.

It is better to choose a leave-in care according to the type of your hair and the level of damage.

It is very important to know that water has a huge impact in providing thermal protection. Therefore, the wetter the hair before applying thermal protection, the more effective the result will be. Do not dry your hair with a towel, just remove excess moisture with your hands and proceed to apply thermal protection.

For a leave-in to also protect from the sun, it must contain a chemical sunscreen, such as octyl methoxycinnamate. Pay attention to the abbreviation SPF and PA ++, they indicate that the product protects the hair from sunlight.
