These are the 13 best fine hair thermal protectants that shield your hair from heat. In the next section, we will discuss why your hair needs a heat protectant.

Why Your Hair Needs A Heat Protectant

A heat protectant safeguards against heat damage. Regularly styling your hair with a hair dryer or hair straightener without a heat protectant can strip off the hair’s natural moisture and oils. Even a celebrity hairstylist would advise against regular exposure to heat without protection. You can lose hair elasticity and your hair can also become dry, brittle, and frizzy. Fine hair heat styling protectors act as a polymer that wraps around the hair strands. Their natural humectants seal moisture, and their infused proteins strengthen hair fibers.

It is important to know what you need to consider before buying a heat protectant. The following guide can help.

What To Consider Before Buying Heat Protectants

  • Ingredients: Choose the ingredients based on your need. Heat protectants come with both natural and chemical combinations. Argan oil, olive oil, and shea butter are some of the best natural humectants that nourish and hydrate hair strands. Choose fine hair heat protectant with natural ingredients.
  • Heat Protection: Not all heat protectant sprays are good at handling extreme heat. Ensure your protectant can handle at least 200o C of heat.

Lindsay Loo, a cosmetologist, says, “Not all thermal products are created equally. Make sure when you are purchasing or researching that the product is best used for direct or indirect heat or both. Example, a thermal protectant that helps against the heat of a blow dryer might not be formulated to protect against the heat of a flat iron/curl wand.”

Frequently Asked Questions

Do we need to put a heat protectant on wet or dry fine hair?

It is preferable to apply a few spritzes of heat protectant spray on dry tresses before using a heat styling tool. This way you can seal your hair moisture better, strengthen the hair, and protect it from thermal damage.

Will heat protectant spray make straighteners or a curling wand burn the fine hair?

No. Heat protectant sprays wrap a protective layer around your strands. They prevent the straighteners or curling wands to burn or cause any kind of damage to your fine hair.

Can we use a heat protectant while applying a keratin treatment for fine hair?

No. Keratin treatment requires a lot of heat in order to fuse the keratin properly to your hair follicles. So, using a heat protectant while applying Keratin treatment is not recommended as it may block some of the follicles. However, to retain the shine of your keratin-treated tresses, you must use a heat protectant to guard your hair against damage caused by the styling tools.

Can hair moisturizer be used as a heat protectant for fine hair?

No, a regular hair moisturizer is not an ideal alternative for fine hair heat protectant spray as it will not protect your hair from severe damage caused by styling tools. A heat protectant spray will act as a polymer around your strands and seal essential moisture, allowing no damage caused by several rounds of styling.

Does styling one’s hair every day damage the fine hair, even if a heat protectant is used?

Yes, styling your fine hair daily with hot styling tools is not recommended even if you use a suitable heat protectant spray. Overusing heat styling tools can lead to brittleness, making the hair prone to breakage and causing it to appear limp and dull over time.
