We will further provide you with our thoughts on the best way to keep your hair safe from damage, even without using a heat protectant.
What is the right hair protection spray?
Heat protectant is a type of spray which can be applied to your hair before blow-drying or heat styling such as using a curling iron.
A good heat protectant creates a shield on your hair that will help to protect your hair from over-heating during the blow-drying procedure.
Although the ingredients used in heat protectant vary, most of the heat protectants contain silicone and polymer as the shielding agents of your hair.
It also includes oils and scents which can moisturize your hair and assist in styling.
Hair protection spray from heat: How it works
The key function of hair protection from overheating is provided by the use of heat protectant during your haircare regimen.
You can use a protectant before you style your hair with the help of curling irons and straighteners, but you can also use the protectant before you blow dry your hair.
Overheating your hair with the excessive application of heat through a hair dryer, straighteners or curling irons may lead to the degradation of keratin proteins in your hair.
In addition, moisture evaporates from your hair when heated, causing your hair to dry out and even break.
Using hair protection spray will help reduce the risk of overheating your hair when drying and styling.
Although a hair protection spray doesn't provide 100% protection, studies show that using such products leads to 20% less damage.

The secret behind heat protectants is in formation of a thin film layer on your hair that reduces heat conductivity by evenly distributing the heat throughout your hair.
Silicones are characterized by lower thermal conductivities; therefore, they do a good job in slowing down heat transfer.
Hence, although heat protection sprays will not shield your hair from damage done by a hot dryer or iron, they limit the damage that is done to your hair during drying using high temperatures.

Home-made heat protector spray for straightening hair
While heat protectants work effectively when applied properly, they tend to cost quite a lot, and buying a bottle in order to try them out at home would not seem reasonable.
However, there is always something that you can use without spending too much money:
Argan oil
Argan oil is rightly recognized as the perfect heat protector spray for curling and straightening hair.
All you need to do is to apply some Argan oil to your hair ends before styling them with the help of curling or straightening irons.
Argan oil is rich in antioxidants, its smoke point being 420 degrees.
So, it is a wonderful ingredient to use to protect your hair during the process of drying or styling. Here are the best oils for dry scalp.
Coconut oil
There are numerous benefits that coconut oil offers as a hair care product.
Apart from being used as a hair conditioning product, coconut oil can also be used as a sealant on medium thickness hair to provide protection from heat exposure.
Even though the smoke point of coconut oil is relatively lower compared to the smoke point of Argan oil at 350 degrees, it's a good solution as a heat protectant spray for curly hair, wavy hair, and thick hair.
Grapeseed oil
When considered as a home remedy, grapeseed oil is one of the best heat protectant sprays that can be used to take care of your dry hair.
Its smoke point is 420 degrees and it also acts as a treatment option for hair problems such as dandruff and even dermatitis.
Another good point about grapeseed oil is that it keeps moisture in your hair cuticles.
The verdict: Is heat protectant spray good or bad for your hair?
No worries, heat protectant spray is not bad for your hair. You may purchase a protectant spray and then use it on your hair prior to using blow dryers, straighteners, and/or curling irons. In most cases, it will provide extra protection and may have some moisturizing effects as well.
However, it's not the most effective method of protecting your hair from heat.
At Laifen, we would like to recommend you using an ionic hair dryer with adjustable temperature settings, such as Laifen Swift Special.
Thus, you may dry your hair at low or medium temperatures to avoid hair damage from excessive heat.
Also, Laifen Swift Special comes equipped with a diffuser attachment that you can use to dry your curly or wavy hair.
This feature allows you to ensure the proper distribution of heat across the hair's surface.
