Best Heat Protectant for Natural Hair

After putting in so much work and effort into keeping your hair healthy and lustrous, it would be a shame to throw it all away due to heat damage. Heat styling can cause our hair cuticle to open up. This destroys the keratin in our hair that provides strength and elasticity to our hair strands.

Excessive heat isn’t good for hair, but that doesn’t stop us from using flat irons, blow dryers, and curling wands to achieve that perfect look. Since styling has become routine in many women’s beauty regimens, we’re giving you ideas on how you can protect your hair from heat damage. 

One of the key ways to prevent heat damage is by using the best heat protectants.

All of HSI’s hair care products are manufactured in the US. Its antioxidant-rich ingredient argan oil has vitamins A, B, C, and D. Together these nutrients protect your hair from heat damage while keeping your hair shiny and healthy.

Things to Consider when Buying Heat Protectant

Temperatures

Regardless of whether you choose to style hair with low or high heat temperatures, it is always better to have heat protectants that can protect against heat of up to 450 degrees Fahrenheit. 

Moisture

Some products have ingredients that help keep your hair’s moisture. Heat styling tools by nature can be very drying. Heat protectants are hair products that can help counter the drying effects of these tools. Without them, there is a higher chance of drying and even damaging your hair. 

Consider heat protectants with moisturizing ingredients like sunflower seed oil and sunflower seed extract, shea butter, and silk amino acids. You may also want to look at leave-in conditioners like It’s A 10 Miracle Leave-In Conditioner Spray.

Natural Ingredients

The use of natural ingredients in hair products ensures the integrity of your hair is not compromised. It also helps to protect your hair from any chemical damage. Keep an eye out for products with ingredients like shea butter, coconut oil, proteins, argan oil, olive oil, fennel seed oil, wheat protein, etc.

What Is The Best Heat Protectant for Natural Black Hair?

We think that the best protectant for natural hair that has not received chemical treatments is L’Oréal’s Paris Advanced Hairstyle Sleek It Iron Straight Heatspray. We like the fact that their heat protectants save your hair from heat damage while keeping your look intact for up to three days. 

Do Hair Heat Protectant Sprays Really Work?

Yes, they do. As you might have noticed from our reviews, a hair spray can do more than just protect from heat damage. It can also be formulated to address related issues that heat styling can cause such as dry, frizzy hair, and split ends. You will protect your hair from a lot of damage by simply adding a heat protection spray to your daily styling routine.
