Best Heat Protectant Buying Guide

If your hair looks unruly and almost unrecognizable, then, it only means one thing, your hair is damaged and needs saving. After listening to friends and researching online, you will realize that there are countless products which could be the best for your hair. Confusing, isn’t it? Fret not because we’ve got you covered.

How to Choose the Best Heat Protectant

Look at the level of heat temperature protection

When looking for the best heat protection spray, you should look at the level of protection offered by the hair spray. The best protectant will safeguard your hair at temperatures of about 450 degrees Fahrenheit, and others offer a higher level of protection.

However, just because the protectant protects your hair at such high temperatures doesn’t mean that you should use such harsh products. Always choose gentle blow dryers and flat irons.

Type of heat protectant

Two ingredients make up heat protectants – Cyclomethicone and Dimethicone. The combination of these two compounds in treatment sprays, leave-in conditioners, setting lotion and straightening serums makes such products heat protectants.

Heat protectants reduce the molecular breakdown of hair and prevent hair from drying out retaining the water in every strand of hair. With hair holding enough moisture, it prevents the cuticles from cracking, and this allows your hair to keep its strength and bounce.

What are these compounds and why use them in heat protectants?


This is clear silicone which boasts a sleek and smooth feel on the hair. Cyclomethicone evaporates easily from the hair, and this helps in transferring nutrients and oils into your hair shaft making the shafts more resistant to damage.


This is a form of silicone used in detanglers and conditioners to help in smoothening your hair making it easy to comb through hair. Since dimethicone covers hair strands, hair looks sleek after styling.

Both these silicone compounds are FDA-approved, and they are safe on your hair and the skin.

Benefits of Heat Protectors

  • Here is something we often forget about our hair – hair is delicate and dead fiber. Once it emerges on the scalp, it doesn’t have any active cells remaining meaning that it is prone to damage. The absence of live cells means that hair cannot repair itself in case of damage.
    Heat destroys hair at the molecular level by damaging the structure of keratin. Eventually, you will have frizzy hair with brittle split ends so; you need to protect your hair.
  • They lower the rate of moisture loss from hair making your hair stronger and healthier. Your hair may have lost moisture because of over processing or over-exposure to dangerous chemicals.
  • They decrease your hair’s porosity making your hair less prone to dampness after heat treatment or styling.
  • The protectors lubricate the surface of the hair making detangling easy and your hair smoother.

Factors to consider when looking for a heat protectant



The best heat protectors have safe ingredients that encourage the growth of healthy hair. The two important protectant ingredients are dimethicone and Cyclomethicone as they protect the hair. These two are FDA-approved, and they are safe for use by humans.

The other ingredients include vitamins and natural oils or natural proteins that encourage healthy growth of hair. You should avoid products with sulfates, parabens, and cheap or carcinogenic fillers.


Your hair type

A heat protectant protects your hair strands from direct exposure to heat but, you can’t expect any protectant to work on your hair. Because of differences in the types of hair, there are different types of heat protectants for hair.

Black hair

Natural Hair

Fine hair

Colored hair

Frizzy hair

Fine and greasy hair


Frequency of heat styling

If you use heat styling tools regularly, then you have to find a heat protectant able to withstand high temperatures. You want to use a gentle styling product because your hair can only take too much heat before you get split ends and hair breakage.


Effects on your hair’s weight

How will the protectant feel on your hair? Will it increase or retain the body and bounce of your hair? You will also want to know if the protectant improves the texture of your hair and if makes your hair softer, shinier and healthier-looking.
