10 Best Heat Protectants 2025 in the UK

The OGX Argan Oil of Morocco Shine+ Heat Protection Spray is designed to protect hair from heat damage caused by styling tools, offering defense up to 230°C. It is suitable for all hair types and features a blend of Argan Oil and Shea Butter, which helps condition and smooth the hair, providing a salon-quality finish at home.

In addition to heat protection, this spray aims to reduce blow-dry time and impart a silky shine to the hair, making it more resilient and manageable. The product is easy to use—simply spritz on damp hair before styling with heat tools. One of its major strengths is the inclusion of high-quality ingredients like Argan Oil and the fact that it is free from Sodium Lauryl Sulphate, making it a gentler option for daily use.

However, the spray is unscented, which may not appeal to those who enjoy fragranced hair products. Additionally, while it claims to offer flexible control, it might not provide the hold needed for more complex hairstyles. This product is particularly beneficial for individuals who frequently use heat styling tools and seek to maintain hair health and shine.

The ghd Bodyguard Heat Protect Spray in travel size is designed to offer robust protection for your hair against the damage caused by heat styling tools. This product features the ghd heat protection system, which blends protective polymers and conditioning agents to keep hair cuticles intact, resulting in sleeker and smoother hair. It's suited for all hair types, making it versatile for a wide audience. The spray forms a thermal protective layer on hair, effectively creating a barrier against heat, with many users reporting that it leaves their hair looking and feeling healthier.

The formulation is lightweight, offering an invisible, non-greasy feel that won't weigh your hair down, which is a significant advantage for those who prefer a natural look and feel. It also provides additional benefits such as UV protection and damage control, making it a comprehensive option for hair care during heat styling.

In summary, the ghd Bodyguard Heat Protect Spray is ideal for someone looking for a reliable heat protectant that's compact and easy to use, especially frequent travelers or those who need a quick fix for on-the-go styling. On the downside, the product's travel size means it's only 50 milliliters, which might not last long for regular users. While it's free from sulphates and parabens, it is unscented, which may or may not appeal to those who enjoy fragrant hair products. Additionally, despite its compact design, it might be a bit pricey per milliliter compared to larger bottles or other brands.

Kérastase Nutritive Nectar Thermique is designed as an anti-frizz blow-dry milk specifically for medium to thick dry hair. One of its strongest features is its capability to protect hair from heat up to 230°C, which is crucial for those who regularly use heat styling tools. This makes it suitable for users looking to shield their hair from potential heat damage. Additionally, it contains specially selected polymers to increase smoothness and shine, making it easier to manage and style hair, while also providing a layer of humidity protection which is beneficial in maintaining moisture balance in humid conditions.

The product stands out for its detangling benefits and ability to enhance the softness and suppleness of hair after each application. This can be particularly advantageous for individuals with dry hair who struggle with tangling and rough texture. The formulation as a milk allows for easy application and distribution throughout the hair, which can streamline the styling process.

However, it's important to note that this product is tailored to medium to thick hair types, which might not yield the same results for those with finer hair. Users with fine hair may find it too heavy or rich, potentially leading to unwanted residue or a greasy feel. Furthermore, while the product is effective in several other benefits like shine and softness, it may not address specific issues like split ends or deeply damaged hair. For optimal results, it's recommended to use Nectar Thermique as part of the Nutritive range from Kérastase, which could be an additional investment for users. Despite these considerations, for those with the appropriate hair type, it offers a comprehensive solution for heat protection and hair manageability.
