If you use heat-styling tools regularly (or even if you just blow dry your hair), then it’s important to use a quality hair styling heat protectant that shields strands from damage. The protective formulas, typically available in spray, cream, or oil form, work by creating a barrier between your hair and your hot tool, slowing down the rate at which heat penetrates the cuticle. They also help tame frizz, condition strands, and add shine—and some can even block out humidity.
But what’s the best heat protection for your tresses? We asked some of our top stylists to weigh in on the topic and to share their favorite picks.
According to Gretchen Friese, Salon Director and Hair Stylist at Foushee Salon in Denver, CO and a BosleyMD Certified Trichologist, the goal of any heat protectant is to reduce the damaging effects of applied heat. Heat can strip strands of their natural oils and proteins, breaking down the hydrogen bonds that give them their strength and flexibility. Heat protectants work by coating the surface of strands with a thin layer of protective gel, which helps to create a buffer between your hair and heated tools to slow down the penetration of heat so that it doesn’t cause as much damage.
The right heat protectant will be thick enough to form a protective coating, but thin enough to let the air through to the roots and scalp to keep strands from drying out. It should also be water-resistant, so it won’t wash away in the shower or during a rainstorm. Finally, it should be non-greasy, so it won’t feel heavy or greasy on the scalp.
If you’re looking for a lightweight hair styling heat protectant, look for a product with ingredients like humectants and amino acids that seal in moisture, keeping strands smooth, soft and shiny. Shea butter is another good ingredient to check for, as it protects against damage from heat and sun exposure, as well as adds nourishing moisture.
Another key consideration is whether or not the heat protectant is compatible with your style and lifestyle. Some products require wet application, while others work just as well with a dry blow-drying or styling session. It’s also important to remember that applying a heat protectant regularly can lead to buildup, so you’ll want to consider adding a clarifying hair wash to your routine every week or so to prevent that buildup.
You can also make your own DIY hair protection spray at home by combining shea butter with other natural oils with high smoke points, such as coconut and avocado oils. It’s essential to note that each oil has its own smoke point, which is the temperature at which it starts to burn. If you use too much shea butter or a higher-smoke point oil in your DIY protectant, it could burn and damage your hair, instead of protecting it from the heat.
