Do you really need a heat protection spray?
Lustrous and smooth is what most of us would like its hair to be. To reach this goal we run the hot plates of a flat iron along the strands every morning. And even though the effect is achieved, it doesn’t last. Soon the hair will turn brittle and dull. Why? Simply because the heat deprives hair of moisture. It should be also realized that the high temperatures are also infamous for making keratin bonds weaker, which leads to spilling and damage. Furthermore, when exposed to heat, cuticles rise, leading to frizz and tangling.

And to make choosing the right product easier for you, we have tested five most popular heat protectants that keep the hair safe as you straighten it.
