Cantu shea butter thermal shield heat is another product that you should take the time to try out as it is designed for those with textured hair.

You can prevent heat damage from happening by applying this protectant by Cantu on your hair. What you’ll love about this item is that it contains shea butter which is commonly known for delivering plenty of moisture not just to your skin, but to your hair as well.

The shea butter is the one that keeps your hair soft and smooth regardless of your hair type and style. Be proud of your natural curls and waves by using Cantu thermal shield heat protectant.

How Does It Work?

High-grade heat protectants contain specific ingredients such as humectants which are known to fight off frizz and split ends, amino acids that deliver nutrients needed to strengthen hair, and plant extracts, and natural oils that are known to seal the cuticle of your hair to reduce breakage. When applied to your hair, they will create this protective barrier that will reduce the damage to your mane significantly especially when you will be using styling tools on them. They need to be applied prior to using any heat-generating equipment.

There are certain hairstyles that will require the use of a protectant such as straightening your mane, aiming for that slick back style, and even beachy waves too just to name a few. Any time that you use a styling tool you should apply a heat protector first to minimize any damages that may be caused by high temperatures.

How to Choose a Heat Protectant for Hair

If you want to protect your hair from heat damage, you should definitely look for a heat protectant product to include in your list of hair products to get. However, there are dozens of heat protectants available in the market that it can be tough to find the right one for you. The best way to narrow down your options is by considering the following factors:

Offers Maximum Protection from Heat.

Since you are looking for a heat protector, you should choose one that will be able to offer you the highest level of protection against heat. One particular ingredient that should be listed is silicone since it plays a part in coating your mane with a protective covering that will lessen the possible damage. If you are going for a heat protectant spray, you should check if there are dimethicone and Cyclomethicone. This two keep your mane feel smooth and soft.

Fights Frizz.

It is also a good idea to look for heat protectant sprays that come with ingredients that can tame or keep frizz at bay. This is essential when you are going to use a hair straightening tool since the hot plates may cause your hair to become burned. Applying a protectant against heat can help keep frizz at bay.

Moisturising Properties.

Your hair will need moisture if you will be constantly exposing it to high temperatures. With enough moisture, you will be able to correct any damage to your mane. Like it was mentioned before, there are products to protect hair that also come with moisturizing properties which you should look for. Ingredients like shea butter, aloe vera, or glycerin will help lock in the moisture thus minimizing the effects of styling tools on your mane.

Check for Keratin.

Since our hair is made of a protein called keratin, it is only right that you look for protectants that contain this ingredient. One reason why you should look for a product that has this feature is that it will help strengthen your mane by locking in the moisture.

Price.

If you want to buy something to protect your hair against heat, then do not forget to consider the price of the products. The expensive ones don’t automatically mean that they will be effective. This is why you need to compare features and prices before making any purchases. There are those that are priced cheaply but can give good protection from intense heat.

Wrap Up

Exposing your hair without proper protection is inviting problems in the long run. Whatever your hair type, it’s crucial to a protectant before picking up a styling tool. If I had to pick a favourite, I would opt for Evo Icon Welder Heat Protection Spray.

It’s perfect for hot tools, sun exposure, hair styling and comes at a very affordable price.
