How does heat damage hair?

Hair is mostly keratin, the protein that gives it structure and strength. High heat from straighteners and curling irons weakens those protein bonds, leaving hair dry, brittle and prone to split ends — which is exactly what a heat protectant is there to prevent.

How does heat protectant work?

Heat protection sprays and creams form a protective barrier around each hair strand. They typically contain silicones, polymers, and natural oils that work together to reflect heat away from the hair. These ingredients can create a thermal shield, which helps to minimise moisture loss and maintain the hair’s integrity during styling.

Do silicones protect hair from heat?

Silicones are a key ingredient in many heat protectants due to their ability to withstand high temperatures. They coat the hair shaft, providing a smooth surface that reduces friction and prevents damage. Additionally, silicones can enhance shine and reduce frizz, making them a popular choice in styling products.

How to choose a heat protectant

When selecting a heat protectant, consider your hair type and the styling tools you use. For finer hair, lightweight sprays are ideal, while thicker hair may benefit from creams or serums that provide extra moisture. Always apply the product evenly throughout the hair, focusing on the mid-lengths and ends.

More ways to protect hair from heat styling

Incorporating heat protection products into your routine is just one aspect of maintaining healthy hair. Regular washing and conditioning, as outlined in The Right Way to Wash Your Hair, can further enhance hair health. Additionally, consider the benefits of regular trims to remove split ends and improve overall hair appearance.

In conclusion, heat protection products are essential for safeguarding hair against the damaging effects of high heat styling tools. Understanding their composition and function can help elevate hair care routines and promote healthier hair.
