If you're a slave to your GHD's, then L'Oreal's Elnett Heat Styling Sprays should be gracing your bathroom shelves.
There are three products in the range, for tailoring the exact result you're looking for, whether it's straight, curly or full of volume.
I'm particularly partial to the curls version, which I've been using along with curling tongs to create loose waves.
I apply the spray liberally to damp hair, blow dry my hair roughly with my hair dryer, then curl random sections of my hair with the tongs.
The spray promises three days of hold on the bottle, and it lives up to its name. I find that it locks in the style without weighing down my hair or leaving it looking dull and loaded with product.
