One of the best ways to keep your hair looking luscious and healthy for longer is to use a heat protection spray prior to styling.

Designed to create a shield between your hair and heated styling tools, including hairdryers, straighteners and curlers, a bottle of quality heat protectant can also keep the frizz at bay, resulting in a smoother, sleeker finish. 

From ghd to Olaplex, Keratase and Aussie, we've tracked down the top-rated and bestselling heat protection sprays on the market – and they're worth their weight in gold.
