How Heat Protectant Works & Why It’s Important

If you come into the salon complaining of dryness, brittle ends or breakage, chances are your stylist will ask “what are you using for heat protectant? We get that there are a lot of hair myths out there, but let’s start by clarifying: yes, hair protection does work and yes, it’s important to always use it if you're using heat styling tools.


In this article we dive into what heat protectant is, why it’s important and how to use. We’ve also pulled together a list of our favorite hair protection products for different hair types!


What is heat protectant

Think of heat protectant as a form of armor for your hair against your heat tools. Most hair protectants include three main items, though ingredients often differ by product. First, you’ll often find humectants like panthenol or propylene glycol in these sprays and creams, which are added to preserve moisture and block frizz. Amino acids like keratin are also often found in hair protectants, and they work to strengthen by providing antioxidants. Lastly, a moisturizing ingredient like aloe is often used to protect and seal each strand’s cuticle.


Why it’s important

Well there’s the obvious answer, which is that heat protectant works to prevent and reduce damage to your hair from heat styling. Without it, hair subjected to heat styling is easily damaged, resulting in higher amounts of breakage, brittle hair and split ends (that lead to even more breakage). Most heat protection products will protect hair from heat styling up to 450 degrees, so make sure to pay attention to the temperature of your heat tools to avoid overdoing it.


Keep in mind that like any product, use can cause coating and build up over time. To keep your scalp and hair clear, use a clarifying shampoo once a week to remove build up and start fresh.

Continue with other necessary hair products like mousse, then your hair is ready for blow drying and heat styling.
