Using too much can cause more damage, so what’s the right proportion? We have curated this report to answer your queries.

How Much Heat Protectant Should I Use?

How Much Heat Protectant Should I Use?

Well, it depends on the length of your hair and the product’s consistency. You can generally use either a spray heat protectant or an oily one. 

For Long Hair

Long hair is often unmanageable and is said to be around 10 to 20 cm below the shoulders. So in case you fall into this category, here’s your guide.

If you opt for an oily heat protectant, then it’s best if you go with a small amount of heat protection spray around the size of a walnut. 

  1. Spray the protectant once on every section of your hair.
  2. Make sure you massage your hair well and comb them from the roots to the end, so the protectant is spread throughout.

However, if you go for a liquid heat protectant, follow the steps below to know how much heat protectant to use.

  1. Since it is a liquid spray, you must ensure that all sections of your hair get the right spray. Squirting the spray all at once can drench your hair with the protectant and make it saturated. This will only make you look like someone who tried doing something to their hair but utterly failed.
  2. Divide your hair into sections. Spray about two times at every section. Ensure you keep the spray bottle at least 15 cm away from your hair. 
  3. If you have thicker hair, you can respray it until you feel all the sections have enough spray. 
  4. Comb your hair from the roots to the end to evenly distribute the product.

For Mid-Length Hair

Mid-length hair is nothing but chest-length hair and is relatively easy to manage. 

For mid-length hair, if you choose an oil-based heat protectant, then follow the steps:

  1. A good coin-sized amount of protectant will work well for shoulder-length hair. By taking this amount of protectant, massage your hair.
  2. If you feel an excess product, run it from the roots to the ends of your hair.
  3. Comb your hair for good distribution.

If you choose the liquid spray protectant, then:

  1. About six to seven protectant sprays should be good for a mid-length. 
  2. Spray it about two or three times by keeping the spray bottle at a distance.
  3. Then comb your hair and respray it about two to three times on the inner layers of the hair.
  4. Comb your hair from the roots to the ends.

For Short Hair

If you’ve got short hair, meaning the length is around 5 to 10 cm above the shoulders, you can get the job done quickly.

For an oil-based protectant:

  1. The size of a small coin can be enough for small hair.
  2. Rub the amount of product on your palms and apply it well from the roots to the ends.
  3. Make sure you cover the inner layers of the hair as well.
  4. Comb well to distribute the protectant.

If you use a spray protectant or the liquid one, then:

  1. Keep the bottle at a distance and spray about five times on your hair.
  2. Ensure you don’t saturate a single section of your hair and leave the others dry. Hence cover all the surfaces layer by layer.
  3. Comb your hair from the roots to the ends to distribute the excess.

After using heat protectant sprays, wait for them to dry completely and then move on with the flat iron or curler. If you immediately go with the heat, then it might make your hair stiff and make it look like a hair gel to set your hair.

Frequently Asked Questions

Do I really need a heat protectant spray?

Heat protectant sprays do not prevent hair damage but work on minimizing the damage that is caused due to direct heat applied to your hair. So, using it every time you heat your hair is best, especially when you have treated hair.

How does a heat protectant spray work?

The protectant forms a layer to your hair and helps keep it safe from the heat produced by the heating irons or tools. 


Styling your hair is essential, but not damaging them while acing the look is also important. Just as you take good care of your skin before applying makeup, your hair also needs such attention! So before you make your hair undergo excess heat to be styled perfectly, ensure they’re masked up with good products like heat protectants that will reduce the damage, if not wholly prevent it.
