The Power of Kérastase Heat Protectants

Care and Style Without Compromise

Using a heat protectant is extremely important when using heat styling tools on your hair. Heat protectants create a barrier between your hair and high temperatures, helping to minimize damage and protect your hair from breakage, dryness, and split ends. Heat styling tools such as blow dryers, straighteners, and flat irons can reach hot temperatures that can weaken the protein structure of your hair, leading to damage. Heat protectant sprays typically contain ingredients that help to absorb and distribute the heat evenly, reducing the direct impact on your hair.
By using a heat protectant, you can minimize the negative effects of heat styling and maintain the health and integrity of your hair. It can also help to preserve your hair's natural moisture, prevent frizz, and enhance the lifespan of your hairstyle.

The heat actually empowers the actives in the product to add strength to the hair fiber from the inside out.

What should you look for in a heat protectant?

Heat Protection: Look for a heat protectant that specifically mentions heat protection on the label. It should be able to withstand 450-degree temperatures and provide a barrier between your hair and the heat styling tools.

Ingredients: Look for heat protectants that contain ingredients like silicones, polymers, or ceramides. These ingredients help to coat the hair shaft, seal in moisture, and provide a protective layer against heat damage.

Hair Type: Choose a heat protectant that is appropriate for your hair type. If you have fine to medium hair, opt for a formula that is lightweight and will not weigh your hair down. If a formula is too heavy it can make your hair feel greasy or limp. If you have thicker or coarser hair, opt for something that will help tame your frizz and keep your style in control.

Application: Consider the application method that suits your preference. Heat protectants are available in various forms such as sprays, creams, serums, or oils. Choose one that is easy to apply and distribute evenly throughout your hair.

Remember, it is important to follow the instructions on the product and apply the heat protectant to damp or dry hair before using any heat styling tools.

How to choose the best heat protectant for your hair?

To choose the best heat protectant for your hair, consider the following factors:

Hair Type: Consider your hair type and specific needs. Different heat protectants may work better for certain hair types. For example, if you have fine or thin hair, you may want to choose a lightweight spray or serum that will not weigh your hair down. If you have thick or coarse hair, a cream or oil-based heat protectant may provide more moisture and protection.

Heat Styling Frequency: Consider how often you use heat styling tools on your hair. If you frequently use heat styling tools, you may want to opt for a heat protectant with stronger heat protection and long-lasting effects.

Desired Results: Think about the desired outcome of your heat styling. If you want sleek, straight hair, look for a heat protectant that also offers smoothing properties. If you are aiming for voluminous curls, choose a heat protectant that helps to hold volume and reduce frizz.

How should you use a heat protectant?

To effectively use a heat protectant, follow these steps:

Start with clean, towel-dried hair: Apply the heat protectant to damp hair after washing and conditioning. Gently pat your hair dry with a towel to remove excess moisture, leaving it slightly damp.

Apply the heat protectant: Spray or apply the heat protectant evenly throughout hair, focusing on the mid-lengths and ends. These areas are more prone to damage from heat styling tools. If using a spray, hold the bottle about 6-8 inches away from your hair to achieve an even application. If using a cream or serum, dispense a small amount onto your palms and distribute it through your hair.

Comb through: Use a wide-toothed comb or your fingers to comb through your hair, ensuring that the heat protectant is evenly distributed from roots to ends.

Style as desired: Once the heat protectant is applied, you can proceed with heat styling your hair using tools like blow dryer on damp hair and a straightener on dry hair. Remember to adjust the heat settings to a safe and suitable temperature for your hair type.
