What should you check before buying a heat protectant



Always check the label! You really should avoid applying products on your hair which contain harsh chemicals or at least you should understand the chemicals that you are going to use on your fragile hair otherwise, you may end up losing money on products which will harm your hair.

Quality heat protectants contain ingredients like amino acids( usually keratin), natural oils and extracts( usually argan oil) and humectants( like propylene glycol) and for providing insulation for the high temperature, a good heat protectant should contain silicones( like Cyclomethicone). 

Try to avoid products that contain alcohol. Gray hair is naturally drier, brittle and coarser than pigmented hair, therefore putting alcohol on your hair will only dry it further.

Sulfate-free hair products are better for dry or frizzy hair because sulfates can lead to a loss of moisture. If your hair is dyed it is recommended to use sulfate-free products as they are less likely to wash away your hair dye. If your hair is tortured from hot tools like flat iron it is also recommended to use sulfate-free products as are more likely to repair your hair.

Try to use products which contain essential oil. The most popular oil in the beauty industry is the argan oil and it’s recommended for gray hair too, as it is rich in vitamin E and fatty acids. It usually is combined with jojoba oil which contains vitamins and minerals essential for healthy hair.  

Types of heat protectant for hair

Hair heat protectants can be found in different types such as spray heat protectants; oil, cream, milk and lotion heat protectants. Spray type of heat protectant is more suitable for fine and thin hair and it’s easier and quicker to use, where a thick or coarse hair needs an oil, leave-in conditioner, cream, milk or lotion as they will moisturize better.  

Please notice that not all hair products are vegan, therefore if you are looking for a vegan heat protectant you should check the label first. 

Consider the brand

As you don’t want to damage your hair with poor quality products that contain any harsh chemicals, you should consider products from reputable brands that are mainly focused on hair products. Brands specialized in hair products invest much more money and do more elaborate tests on their products before selling them, therefore the chance of ending up with a poor quality product is lower.

However, this thing may also increase the cost of the product, but no one should trade the hair’s health for a couple of bucks. Most of the times, really cheap products are not properly tested, it is your duty to do some research about a hair product before purchasing and applying it as in some cases it can prove harmful (even wrong usage can cause harm), therefore it is recommended to get information about the testes passed by the product and to apply it following the instructions.


Final Recommendation 

In order to achieve your dreamy hair, you should invest time and quality products, especially if your hair color is gray. Fortunately, there are several good products you can find on the market, therefore you can find products which will not only protect your hair from the heat, but will also cut the blow-dry time, will leave your hair healthy, hydrated and glossy, will reduce frizz and will leave your hair manageable, but it depends on the product and its ingredients. 

Also, pick a high-quality iron to protect your hair, and choose the brand carefully. Irons or straighteners made from high-quality materials like titanium, ceramic or tourmaline won’t damage your hair as much as cheap quality materials will do, but even a high-quality iron won’t protect you from damage, but a heat protectant will help you to reduce the damage.

Thus, with a bit of research, it is impossible to not find your winning product.
