A heat protectant is a leave-in spray formula that you apply to your hair before heat styling with a hot tool. It minimizes the damage caused by high temperatures from styling tools like curling irons, hair straighteners, and blow-dryers.

The product acts as a barrier between your hair and the styling tool. It seals in moisture and controls frizz. The nourishing formula smoothens your hair cuticles and adds shine and softness. Many heat protectants also contain anti-humidity ingredients that keep your hair sleek in highly humid conditions. Some also contain UV filters to protect your hair against sun damage.

Frequently Asked Questions

Is heat protectant hairspray necessary?

Heat styling can damage your hair in many ways, making it rough, dry, and brittle. A heat protectant spray can address these issues by strengthening and protecting your hair against the heat damage.

Do you put heat protectants on wet or dry hair?

When blow-drying your hair, apply heat protectant on towel-dried, damp hair. It should be applied to dry hair when using a flat iron.

Can a leave-in conditioner be used as a heat protectant?

A leave-in conditioner might protect your hair from heat styling tools sometimes, but excess of it can cause buildup, making your hair look dull and limp.

Should you let the heat protectant spray dry before straightening your hair?

Follow manufacturers instructions.

Can I use a heat protectant every day?

No. Use a heat protectant whenever you are heat-styling your hair. Skip heat-styling the hair daily to prevent turning the hair dry and brittle.

Do you put heat protectant before or after oil?

Use a heat protectant after applying oil to the hair to lock the healthy ingredients inside the hair shaft and create a barrier between the hair and the heat tool.

How long does heat protectant last in hair?

The effect of a heat protectant can vary but, on average, it lasts for four hours in the hair.

Can you use olive oil as a heat protection spray?

Yes. Olive oil has a high smoke point that makes it a good heat protection spray.
