Best Products to Keep Your Hair Safe as You Style It With a Flat Iron. We’re Reviewing 5 Heat Protectants

Use of a flat iron seems to be an essential part of most women’s daily hair routine. Smooth and sleek, hair simply looks better and helps us look well-groomed. The sad truth is that the abuse of the heat styling tool brings more harm than good – it deprives hair of water, causing brittleness and serious dehydration. To avoid this adverse effect of straightening, you should turn to a heat protectant spray. Why is that? Because only this product is able to shield your delicate hair from the extreme temperatures. Using heat protectants is an absolute must if you often expose your hair to heat.

Having such a huge arsenal of heat protectant sprays in drugstores is both a course and a blessing. How will you know that the product you’re holding in your hand is right for you? How can you be sure that it delivers promised results? This is why we’ve created the following ranking of the best heat protectants, so you don’t need to test all the products on your hair.

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.

To put a stop to the negative impact that a flat iron clearly has on all hair types, you need to introduce a heat protection spray to your daily hair ritual. 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. We analyzed their formula and the strength of protection. Which product turned out the best? See below.
