Heat protectant sprays are specifically designed to create a protective barrier between your hair and heat-styling tools such as flat irons, curling irons, and blow dryers.
They work by coating the hair shaft with a heat-resistant film that helps to minimise the damage caused by high temperatures.
The primary purpose of heat protectant sprays is to prevent heat from penetrating the hair shaft and causing damage.
When you apply heat to your hair, it can lead to a loss of moisture, protein damage, and even structural changes to the hair shaft. This can result in dryness, frizz, breakage, and split ends.
By using a heat protectant spray, you can reduce the amount of damage caused by heat styling tools.
The heat-resistant film formed by the spray helps to retain moisture in the hair, minimises protein loss, and provides a buffer against high temperatures. This helps to keep the hair healthier, smoother, and more manageable.

When it comes to using a heat protectant, it is generally recommended to apply it on dry hair before using any heat-styling tools.
The reason for this is that applying heat protectants on wet hair may dilute the product and reduce its effectiveness.
If you apply heat protectant on wet hair, the water present in the hair can mix with the product and potentially dilute it. This may lead to a less effective barrier against heat and increase the risk of damage to your hair.
To ensure proper protection, it is best to wait until your hair is completely dry before applying heat protectant. This way, the product can adhere to the hair strands and provide maximum protection when heat is applied.
However, there are some heat-protectant products specifically designed for use on damp hair. These are usually labelled as “wet-to-dry” or “pre-styling” sprays.
These products are formulated to be applied on towel-dried or slightly damp hair and can protect against heat while also helping to speed up the drying process.
