The best heat protection sprays to add to your haircare arsenal immediately 

Keep in mind, however, that they don't offer 100% protection - using a high temperature will still cause some damage, even with a heat spray - and they don't offer broad protection from other threats either (like air pollutants).

Having said that, a lot of brands nowadays have created formulas which also condition, nourish, tame strands, protect colour and help to detangle your hair as well as shelter it from scorching temps. How clever? Sounds a worthwhile purchase to us.

Everyone wants 'Cindy Crawford hair' right now, so here's how to get the big, bouncy '90s blowdry of your dreams

Yes! You should be using protectant spray every time you’re styling your hair. “Everybody should use it, it doesn't matter what hair type you are,” says Lewis. This even includes re-styling your hair quickly on day two or three. Trust us, a few spritzes is worth it to keep your hair from unnecessary damage.

Believe it or not, more isn’t always more when it comes to hair product; though, we’ll still need more convincing on that when it comes to conditioner. “The amount someone would use would depend on your hair and hair type so if you had thin fine hair then you could use less than someone with thick hair,” says Lewis.

Lewis says that application technique matters, too. “A quick spritz over the top isn’t going to cut it!” Heat goes all over your hair so you need to make sure as many of your stands are coated as possible.

“The quickest way to apply it would be holding the spray in one hand and grabbing your hair with the other and basically lifting and dropping the hair while you spray, then swap hands to cover all of your hair,” he says. “I’d love you all to do it section by section but we both know that will never happen so try this it’s much easier!” We love an understanding hairstylist.

The answer to this question depends on a few things, the first being what type of hair you have and the second being how much money you want to spend. Have you got curly hair, dry hair, straight hair...?

Say your hair is prone to dryness. The Shea Butter Thermal Shield Heat Protect by Cantu is well worth picking up. Made with pure shea butter to replace vital moisture and reveal stronger, healthier hair with a natural shine, this formula is a pre-treatment for all hairstyles to prevent damage and create smooth results.

A pricier option that's a good heat protecting spray for straightening hair is the trending Balmain Hair's Thermal Spray. Ticking all the right boxes with its ultra-fine spray that defends against all styling tools, it's infused with silk protein and pro-vitamin B5 to create an invisible shield all while protecting the hair from breakage and heat damage up to 220°C.
