How To Make Your Own Heat Protection Spray

Heat protection spray is used to prevent damage to the hair when blowdrying, straightening or using other heat tools. I used to straighten my hair regularly, so heat protection spray was essential for me. Over the years I have tried many different brands of heat protection spray including TRESemmé, Hairburst and John Frieda. I never really stopped to think about what was in them and how they worked.

One day, I ran out of heat protection spray. I needed to straighten my hair but I didn’t have time to go shopping for some new spray. I thought to myself, I wonder if it’s possible to make my own DIY heat protection spray?

Homemade Heat Protection Spray for Hair

Is homemade heat protection spray effective?

With a bit of research, I discovered that yes it is possible to make an effective DIY heat protection spray at home! I had always assumed that there was some complex and magical combination of ingredients in the spray that provided heat protection. But I was amazed to discover that the main way heat protection spray works is simply to coat the hair with moisture before straightening it so that it doesn’t dry out so much.

This can easily be achieved with a homemade, DIY recipe. Of course, there are other ingredients added to commercial sprays that have advanced heat protectant properties. But basically, water and some kind of moisturising oil would still do a good job!

Why make your own heat protection spray?

Here are some of the advantages of making your own heat protection spray:

  • You’ll save money.
  • It’s quick and easy to make.
  • You probably already have the ingredients at home.
  • You’ll reuse a spray bottle rather than buying a new one, so it’s better for the environment.
  • Many heat protection sprays contain potentially harmful chemicals, so by making your own, you will avoid these.

What you will need

When researching the topic I came across various different recipes for homemade heat protection sprays. For mine, I kept it very simple by only using these 3 ingredients that recurred in a lot of the recipes I found:

I already had these ingredients at hand which meant I could make my heat protection spray and start using it immediately. If you don’t have coconut oil, you could use a different oil such as almond or argan oil, or just leave it out.

You will also need an empty spray bottle. I used the bottle from my TRESemmé heat protection spray that had just run out.

How to make your own heat protection spray

  1. Fill an empty spray bottle about 3/4 full with water.
  2. Add a generous squeeze of conditioner.
  3. Add a spoonful of coconut oil.
  4. Close the bottle and give it a good shake.
  5. Ready to use!

I’ve found that sometimes the coconut oil forms clumps in the bottle, especially when the room temperature is cool. This is because coconut oil melts at about 24ºC (76ºF). I usually give the bottle a good shake every time before I use it. Sometimes when my spray runs out and I don’t have any coconut oil, I just use water and conditioner and this obviously solves the problem of clumps!

Nowadays, I tend to leave my hair curly because I have been trying the Curly Girl Method. However, I do still straighten my fringe, so I still use my homemade heat protection spray for that.
