What Is A Heat Protectant Spray?
A heat protectant will create a barrier between your hair and the object exposing your hair to heat styling.
In order to create this barrier, many heat protectant sprays have two emollients in them: Cyclomethicone and dimethicone.
These are silicones with hydrophobic qualities, meaning that they create a seal around your hair cuticle.
This locks moisture into the hair as well as preventing humidity from causing frizz. The result is soft, smooth locks that won’t easily tangle.
There are also some heat protectant sprays that don’t contain silicone. If your hair is particularly thin and prone to being a bit limp, it’s probably best to avoid silicone, as it can cause build-up which weighs hair down.
Why Should You Use Heat Protectant On Gray Hair?
Gray Hair Has Less Oils
Caring for gray hair requires time and patience, and it’s important to use the right products according to the changes your body is undergoing.
Gray hair also has fewer melanocytes in it than non-gray hair, a change in pigmentation that can also cause the hair to become brittle.
If you regularly use heat styling tools – such as straighteners, curling wands, or hair dryers – you need to be sure that you’re helping your hair to protect itself and lock in moisture.
As we’ve hinted, gray hair is more vulnerable to the damage caused by these heat styling tools.
Gray hair is both very porous, but also prone to dehydration and frizz. Heat styling can exacerbate both of these latter qualities in gray hair, leading to exceptionally dry, easily breakable locks.
Gray Hair Can Turn Yellow From Heat Styling
The lack of color pigmentation in gray hair also makes it more vulnerable to dryness.
Surprisingly, heat tools also can cause gray hair to discolor, a side effect that no one wants. Regular use of heat tools on gray hair – if no heat protectant is used – can cause hair to turn either green or yellow.
The color your hair will turn is dependent on the type of water in which you’re washing it. If there’s lots of calcium in your water, using heat styling on gray hair can cause it to go green.
If your hair turns yellow, you might be burning it, or the heat from the tool may be reacting badly with another hair product.
To avoid this discoloration and damage, it’s really important to use the highest quality heat styling tools and the best heat protectant there is.
If you do experience green hair, however, use a shampoo that’s specifically designed for hard water in order to get rid of the tinge and restore gray hair to its natural glory.

Types Of Heat Protectant
There are different kinds of heat protectants. A spray is the most common, but there are also serums, oils, lotions, and creams. The best heat protectant for your gray hair will depend on your hair’s texture.
If you have thin and fine hair, using a spray is best, as you aren’t weighing hair down with extra oil and thereby causing a greasy scalp. If you have coarser, thick hair, you can use heavier products like serums or oils, but sprays will still work well for you.

Ingredients To Watch Out For
You’ll typically find the following ingredients in a good heat protectant:
- Humectants. These locks in moisture, ensuring that gray hair is kept luscious and elastic.
- Amino acids. Usually keratin or collagen, these work to restore and support the protein of hair.
- Natural oils and extracts. The purer the oil, the better the heat protectant.
You want to avoid a heat protectant with sulfates and alcohol in. Gray hair is already prone to coarseness, dryness, and brittleness – these ingredients will only dry hair further, leading to moisture loss and frizz.
Some heat protectants also have silicone in, as described above. Whether or not you want to use a heat protectant with silicone in is entirely up to you.
There’s disagreement about whether or not to use products with silicone in them, but it’s generally agreed that silicone has a number of benefits for hair. These include:
- Reduces the porosity of hair, leading to smoother, sleeker hair
- Traps moisture into the hair, and therefore has a conditioning effect
- Lubricates the hair strands, thereby acting as a great detangler and helping to tame frizz and flyaways.
As already mentioned, if you have thin hair that’s prone to lacking volume and looking a bit limp, it’s probably best to avoid a heat protectant with silicone.
That said, silicones are the most effective way to create a barrier between your hair and the heat styling tool.
If you do opt for a heat protectant with silicone in, be sure to use a clarifying shampoo once every week in order to remove build-up. This is a good way of ensuring balance so that your gray hair gets the heat protection it needs but won’t become weighed down by the residue or oiliness of silicone.
