The Power Of Heat Protectants: What Are Its Benefits?


When it comes to hairstyles, nothing matches the effect of curling, straightening or blow-drying your hair using heat. The simple act of aiming heated air at your hair can make it bend to your will in a matter of minutes, totally transforming your look.

Of course, this blow-dried/heat-styled gorgeous hair comes at a cost. It can be difficult to get it right, and it can be damaging to the hair if not done correctly. Read ahead to know how you can style your hair to your heart’s desire without damaging it in the process.

What is a heat protectant & why do you need it?

Constant use of heat styling tools can make your hair dry, brittle and prone to damage. This is exactly why you should add a heat protectant to your styling routine.


A heat protectant for hair is a leave-in product used before applying heat to style your hair. It provides a protective layer over your hair to reduce the heat damage caused by styling products like curlers, straighteners and blow dryers. Not just that, it adds moisture and shine to your hair while creating a protective barrier against heat. Read on to know more and to find a heat protectant that suits your hair:

What are the benefits of heat protectants?

1. Adds Nourishment

Your hair needs moisture and can’t do without it for even a day. You are often recommended to use good conditioners that could give your hair enough nourishment. Heat protectants can help seal this moisture and even amplify it with nourishing ingredients. They form a layer on the shaft of your hair trapping moisture as you heat style your hair. Enriched with skincare ingredients like niacinamide, the Nutritive Nectar Thermique Blow Dry Primer helps to lock in nutrition, strengthening the fiber barrier for long-lasting health, all while offering 230°C thermic protection!




2. Reduces Frizz

Heat protectants soften your hair shaft's cuticles. In humid conditions, they reduce the porosity of your hair and reduce frizz. You can finally say goodbye to frizz caused by heat styling by using the Discipline Keratine Thermique Blow Dry Primer. It is perfect for fine, unruly hair that needs smoothness and manageability. Its unique Thermo Protecting Agents coat the hair fibre, protecting it from heat styling tools up to 180 degrees!

3. Increases Manageability

You often spend a lot of time in the morning styling your hair and making it look presentable. Adding a heat protectant to your styling routine will reduce a lot of effort. As mentioned above, it provides moisture and seals it in your hair. As a result, the moisture keeps your hair lubricated and makes it more manageable. The Genesis Défense Thermique Blow Dry Primer is created with Ginger root and Edelweiss Native Cells which protect your hair from external aggressors, reduce breakage and give you detangle-free hair before you heat style it.


How to use a heat protectant?

Heat protectors come in different types such as sprays, serums, and creams. They should be used carefully to avoid weighed-down tresses. Thin hair should avoid greasy protectants because it has less space to absorb them, while thick hair should use easy-to-absorb amounts.


Apply a heat protectant to your damp hair before styling. Damp or conditioned hair absorbs heat protectants more efficiently than dry hair. Distribute the product evenly even at the back of your head. Make sure you never heat-style wet hair as your hair is extremely brittle to use any heat over it.


You can apply a heat protectant every time you use heat styling tools to style your hair. However, we recommend you to minimize using these tools as they can cause hair damage if used aggressively on a daily basis.


With a heat protectant for hair as a first line of defense, blow drying gets easier, gives better results, and becomes a worry-free way to get the hair you want, whenever it pleases you.
