Heat protectants are designed to help reduce the impact of high temperatures on the hair during blow-drying, straightening, curling and other forms of heat styling. They create an added layer of protection while often helping with smoothing, softness and manageability at the same time.

At Vault, we curate heat protection products across a range of formats, from lightweight sprays and mists to creams, serums and multi-tasking leave-in treatments. Some are designed specifically for blow-drying, while others can be used before straighteners, curling tools or repeated styling.

The right heat protectant depends on your hair type and how you style it. Fine hair may prefer a lightweight spray, while dry, thick or processed hair can often benefit from a more conditioning cream or serum. Apply evenly before heat styling and follow the individual product directions for best results.

A heat protectant helps reduce the impact of high temperatures on the hair during styling. Many formulas also provide added smoothing, softness or detangling benefits.

When should I apply heat protectant?

Most heat protectants are applied before blow-drying or using hot tools. Some work best on damp hair, while others can also be used on dry hair before straightening or curling.

Do I need heat protectant every time I use hot tools?
