We all know how much damage we can do to our hair by over-using those curlers, straighteners and hair dryers and there are many products out there claiming to protect hair but can they really save the day?!

Heat protect sprays all work in a similar way – by leaving a fine film to cover the hair that should act as a thermal barrier and provide some protection. Of course nothing is a complete fix but it can help reduce the amount of damage, which includes degradation of keratin, bubbles interrupting the structure of our hair and a loss of the ability to hold onto that all important water. These sprays should help keep the cuticle of our hair intact and smooth for great looking hair!

There is a huge list of ingredients that can help to do this, so we took a look at 3 well known heat protectors to see if they REALLY work…

GHD Heat Protect Spray

GHD have three ingredients that they claim get the job done! First is sodium laneth, which is added to prevent cuticle lift and maintain strength. There is not a lot of evidence out there to back this up but as it is a polymer, it could work. Polymers are the basis of all heat protect sprays as they coat the hair, reducing the contact between your hair and that hot metal. This reduced contact will provide some protection to our hair.

Hydrolysed wheat protein is next and this has a bit more science behind it. It is thought that this will increase the strength of the hair fibre as well as retain some moisture (we know how important this is as our everyday heat styling leads to complaints of dry hair!). This works especially well when combined with other ingredients such as panthenol, which just so happens to be in GHD’s heat spray too so looking good so far!

Last is thermus thermophilus ferment, this comes from bacteria which live in the deepest and darkest parts of the ocean and as an ingredient it is slowly creeping into our cosmetics! There is little solid evidence at the moment to support this ingredient but we are keeping our eyes peeled for some soon. The ferment is thought to be a good antioxidant so will protect our hair from free radicals.

There are many more ingredients in this spray and most are either there to condition our hair or are a polymer to provide a barrier to the heat. Perfecto!

Verdict: The Geeks think this is a good spray to add to any heat tool addict’s arsenal! Although there’s some research lacking on a couple of the main ingredients, overall we think it’s a good formula to keep hair healthy, hydrated and protected.

TRESemme Protect Heat Defence Styling Spray

This contains many of the same ingredients as the GHD heat spray including the hydrolysed wheat protein (but it’s much lower down on the ingredients list, meaning it’s probably in a lower concentration) and panthenol. However, the second ingredient here is propylene glycol, this (and other glycols) is great for coating the hair fibre to stop the contact between our hair and the heat styling tool to provide some protection. After this is glycerin a humectant commonly used in skin care to moisturise, but this is also important for our hair to look hydrated! TRESemme also include amodimethicone, which is a silicone based polymer known to improve the appearance of hair (shine and smoothness) and is another ingredient, which will coat the hair in a partially heat resistant layer.

Verdict: This is our budget beauty heat protection spray must-have! It’s only £5.25 and does what it says on the tin! This will keep damage at bay without breaking the bank.

John Frieda Frizz-Ease Heat Defeat Protecting Spray

This product also has the propylene glycol and glycerin that create a protecting layer and help to prevent hair drying out, keeping hair healthy. John Frieda also use the sodium laneth that GHD swear by, but we still can’t find much more science behind it to get us excited!

This product claims to combats frizz as well as tackling heat protection, so there are some additional ingredients that are not present in the other two products. It is packed with natural ingredients such as camellia sinensis (a small shurb), jojoba oil, tetterwort, aloe vera and rose extracts. Oils and extracts like these are often found in hair care products to help moisturise hair and keep it smooth, avoiding the frizz. However, the research is limited so the Geeks see them more as a bonus ingredient.

The Verdict: As a heat protection product this spray lives up to expectation but we are less convinced by the combating frizz part. We wouldn’t recommend for fine hair either, as it’s likely to be too heavy due to the number of different oils in the product.
