This toast test proves why using a heat protectant is super important

There are many pieces of beauty advice out there that one may read and think "what a load of crap".

Honestly, aside from using an SPF every day, there aren't that many tips we treat as 'would be upset if we skipped it' musts. And although we know using a heat protectant on the hair before heat styling is a good thing, we didn't realise just how much of a difference it truly makes... until now.

UK-based hair stylist Patrick Wilson has shared an eye-opening video, in which he sprays a piece of toast with ghd bodyguard, the UK version of the ghd unplugged heat protect spray. Using a paper towel to create two halves — one that's sprayed and one that isn't — he then pops it in the toaster to cook. 

The result? The sprayed half is barely any different, while the unprotected side has been subtantially toasted. Not only that, but the flip side of the bread( which had no contact will the spray at all) is even more cooked through.

So if, like us, you were doubting whether heat protect products actually do anything, this video proves they 100 per cent are.

Consider us converted, Patrick.

bh's most-reviewed heat protection products:

John Frieda Frizz-Ease® 3-Day Straight™ Semi-Permanent Styling Spray

"The John Frieda 3 Days straight styling spray does exactly what it claims. It doubles as a heat protectant and keeps my hair smooth and straight for up to 3 days or until I next wash my hair. I do not currently have keratin treated hair but imagine the effects of this would be very similar to a keratin treatment, when I go over my hair with a straightener." - PoshBec 

Kérastase Paris Nectar Thermique

"This product is great for my long, dry hair! I use it before blow-drying and it makes my hair soft and smooth. You only need a tiny amount of the product because it's so easy to work through your hair. It's an expensive product but it will last for ages since you use so little, I would definitely recommend it." -Michelle737

TONI&GUY Heat Protection Mist

"This product doesn't make my hair weighed down or sticky, but it is important to ensure an even spray. I usually spray it into my hands and work it through. I can notice the protection this product offers as the ends of my hair don't feel dry anymore from hair straighteners." - Khajiit
