Introduction to Heat Protectant
Heat protectants are a necessity when you are using a flat iron, curling wand, and blow dryer on a regular basis. The magical shield to heat styling tools is that of using a heat protection spray or serum.

Why Heat Styling is Damaging
Heat (particularly heat over 350°F/175°C) dissolves the natural keratin in hair, resulting in dryness, split ends, breakage, and frizz. Hairs can lose moisture and elasticity and become more susceptible to permanent damage.
What is a Heat Protectant?
It is any product, usually in spray, serum or cream form, that prevents your hair and the hot styling tool coming into contact with one another. It will minimize water loss, avoid breakage and leave your strands looking smooth and shiny.
How Does Heat Protectant Work?
It creates a thin layer on the hair strand for an even heat distribution and reduces direct heat contact.
