Heat Defense Highlight: The Best Heat Protection Sprays To Try

Addicted to your hair straighteners? Prevent frazzled strands with our editors' best heat protection spray (UK) list.

Introducing the best heat protection sprays for styled, unfried hair. Invest in a high-quality heat protection spray and you can enjoy the best of both worlds: safe hair and a killer hair do.

But which spray to choose? To help you out, we explain what heat protection sprays are, what they do, and the best on the market, below.

Why Do People Use Heat Protection Spray?

Most of us, at the very least, use a hairdryer regularly and that’s before we add straighteners and curling wands into the mix.  

Even if your hair looks okay from the outside, heat styling causes internal damage which weakens the hair over time and makes it more prone to breakage. 

But don’t worry, we’re not here to try and convince you to hang up your heated curlers just yet. You just need to take extra care of your tresses every time you use a heated appliance.  

Enter heat protection spray. 

How Do Heat Protection Sprays Work?

Heat protection sprays act like sunscreens do on your skin. They protect your hair from heat by forming a protective barrier over hair cuticles, which also traps in moisture. 

What Defines The Best Heat Protection Sprays?

The best heat protection sprays will defend hair from high temperatures while helping you achieve the style you want.  

What Is the Best Heat Protection Spray?

Want smoother, shinier and healthier-looking tresses with less breakage and split ends? You’d be silly not to! To make your hair dreams a reality, look no further than our editors’ pick of the best heat protection sprays. 

1. The best ‘all-round’ heat protection spray: TRESemmé Heat Defence Spray (Voted Best Heat Protection Spray by ATH)

The TRESemmé Heat Defence Spray contains a heat-activated complex that can help to protect your hair from heat up to 230°C (usually the highest setting on your straightener and curling wand). It is perfect for those who use heated appliances regularly and want to restore shine in their locks, it also offers UV protection. Double win. 

Styling tip: Spray liberally on damp or dry hair and use a wide-tooth comb or a flexible bristle brush to help distribute it evenly before styling your hair. 

2. The best heat protection spray for frizzy hair: TRESemmé Keratin Smooth Heat Protection Shine Spray

As the name suggests, the TRESemmé Keratin Smooth Heat Protection Shine Spray is infused with keratin, helping to tame frizz and boost smoothness, making it one of the best hair heat protectants for girls with curls or natural hair. The results? Smooth and shiny locks no matter what style you’re going for. 

Styling tip: If you’re a prolific user of straighteners, try washing your hair with the TRESemmé Keratin Smooth Shampoo and TRESemmé Keratin Smooth Conditioner first so that your hair care and styling routine can work together. 

Once washed and towel dried, apply the Heat Protection Shine Spray to damp hair, starting from the mid-lengths to the tips, as the ends tend to be the most damaged. When blow-drying, make sure the nozzle of the hairdryer is pointing downwards to help boost the cuticle-smoothing effect. Voila!
