What to Consider Before Purchasing the Best Heat Protectants

1. Ingredients

The best heat protectant spray should have safe ingredients that will encourage your hair to grow healthily because the hair is protected. You should choose ingredients based on the needs of your hair, as heat protectants usually include chemical and natural combinations. It's important to avoid sprays that contain parabens, sulfates, or any cheap fillers since the product is a leave-on and may react with your scalp.

The two main protectant ingredients, which are also FDA approved, meaning they are safe for humans to use, are silicones (Cyclomethicone and Dimethicone) or water-based polymers (polyquaternium and acrylate copolymer,) and they protect your hair. Other safe ingredients you should look for in heat protectants are natural proteins or natural oils such as argan oil, shea butter, and olive oil, as they will boost the healthy growth of your hair by sealing the hair's cuticle. Additionally, humectants like Propylene Glycol attract moisture and lock it in your hair, and amino acids such as keratin strengthen your hair.

2. Hair Type

A heat protectant is responsible for protecting your hair strands against direct heat exposure, but all heat protectants cant work the same on different hair types. Most heat protectant sprays are customized based on different hair types making it necessary to choose one based on your hair type. Therefore, for every hair type, there are specific sprays that will work the best and might not work as well for another hair type.

If you don't know your hair type, you should either look for a professional stylist that will guide you in testing your hair or check for online quizzes that will help you know which hair type you fall under, whether the curly hair, fine hair, dry hair or frizzy hair.

3. How the Protectant Feels on the Hair

You should research how the hair protectant felt on people who used the same to avoid getting a product that will not fulfill your hair completely. Some products increase the body or retain the body of your hair while others improve the texture of your hair, and others make your hair shinier, healthier, and softer.

Depending on what you are going for, ensure you choose the best heat protectant to give you the specific results. Also, look for a lightweight spray formula that will not feel heavy on your hair or leave any residues on your strands. For color-treated hair, opt for heat protectants that have clearly stated they are safe to use on your colored hair, and this is because color-treated hair may need extra attention because of the quick moisture loss that may not be necessary for other hair types.

4. Heat Styling Frequency

How much frequently you use your heat styling tools should determine the heat protectant spray you opt for. If you style your hair regularly, you should opt for a heat protectant that can withstand high temperatures, and also, the styling product should be gentle to avoid any breakage and split ends.

5. Maximum Hair Protection

All of the best heat protectant sprays will handle different amounts of heat, with some being able to handle high temperatures while some can handle moderate temperatures. Before making your purchase ensure the heat protectant, you are interested in can handle a minimum of 200 degrees celsius of heat to avoid any disappointments.

Additionally, to ensure you get the best out of your heat protectant, ensure that your product has silicones in the ingredients because they help coat and guard your hair against heat damage. The most common silicones include Cyclomethicone, which coats your hair with a moisturizing film, and Dimethicone keeps your hair smooth and prevents moisture loss.

6. Applicator Type

The type of applicator in your spray determines how well the heat protectant will be applied to your hair. The best applicator is the spray nozzle that will dispense the protectant evenly in a light mist, and this will help all your hair strands to get evenly coated without necessarily getting your strands damp. Also, for some hair types, the best applicator would be dry spray from an aerosol spray as spray nozzles may wear down the hair with the product.

7. Convenience and Duration

When a heat protectant spray is convenient, you can apply it to damp and dry hair where some products usually need one or the other. People who frequently wash their hair should opt for a spray that works well with damp hair. On the other hand, if you don't wash your hair often but need to spray to touch up your look and style, then go for a spray that will be easily applied on your hair when it's dry that will need no drying time.

In addition to convenience, check to see the lasting capacity of the heat protection spray you are interested in. Some products may last for 24 hours, while others may last up to 72 hours or even your next hair wash day, and choose this depending on your needs.
