2020 Ultimate Buyer’s Guide – Top Rated Heat Protectant for Fine Hair

Anyone who uses thermal products on their hair will know how much damage heat can cause. Curling irons, curling wands, flat irons, hot rollers – even a basic blow dryer can damage hair, making it frizzy and easily breakable in the long term.

This is why you need to consider investing in a good thermal protectant. What happens to your hair when you do not use a thermal protectant is that the heat from your styling product weakens and destroys vital proteins in your hair, and also depletes your hair’s natural oils.

Using a straightening or curling iron can give your hair the look you want, however, excessive use could also damage them. What can one do to avoid this? Well, simply apply a protectant such as a serum, cream, or lotion. This protectant should be easy to apply and should also nourish your hair. However, the market has been overflooded with so many of these protectants which makes it hard to decide which one is worth buying and which one is not.

To help you buy the best heat protectant for fine thin hair, we have compiled a list of our recommendations. At the end of this list, you’ll also find a guide that will educate you on the factors that you should consider when buying or applying.

What Are Thermal Protectants?

Heat protectants are serums and lotions having silicones that protect the hair from excessive heat damage. Each brand makes its own formula and therefore uses different ingredients, resulting in unique characteristics.

Some thermal protectants are better for thin hair while others are for thick hair. Similarly, every thermal protectant has its target category of hair which you can know by reading the label.

Some of these products are packed with other qualities such as nourishment of hair and regrowth process. If you heat your hairs above 230 Fahrenheit, then your hairs are taking heavy damage.

Heat protectants will avoid the damage caused by higher levels of heat exposure. However, it is worth noting that these products cannot completely take away the effect of the heat styling. Even the very best thermal protectant for fine hair can reduce the effect by up to 50%.

Silicones are known to retain moisture in the hairs which reduce the effect of heat treatment. Silicone Quaterniums and dimethicone are also proven to protect the hair during heat styling. Hydrolyzed wheat protein is also formed at the center of all protectants.

Do You Really Need a Thermal Protectant?

If you use any kind of heat styling whether it is a blow dryer or a styling iron, your hairs are exposed to higher temperatures that can damage it. To avoid this damage, you need to apply thermal protectant and some of them can leave a significant impact on your hair.

These protectants can also protect your hair from the harmful effects of the sun. So, yeah, you do need a thermal protectant if your hair is exposed to both conditions mentioned above.

How to Use A Thermal Protectant for Your Hair

It is always best to apply some kind of thermal protectant to your hair before using any kind of thermal styling tool. Before blow drying, you should apply a light heat protectant oil to the ends of your hair to prevent split ends. If you are using a flat iron or a curling iron or wand, it is best to apply a heat protecting spray that has a little hold in it.

In these instances, even a lightweight hold hairspray will work fine but we recommend using a spray that was designed to protect your hair from heat.

It is important to keep in mind that thermal protectants only help to prevent hair damage. You still have to make sure that you do not leave your hair in the clamp of your flat iron or curling iron or wand for too long. Let’s take a look at some of our favorite thermal protectants.
