Yes! Always apply it to freshly washed and conditioned hair that’s still damp. As it is a humectant, it will both help to retain moisture in your strands as well as also attracting additional moisture into your strands too. You'll also find you won't need to use as much gel. Don’t “rearrange” your hair before the gel has dried (especially if you have curls) as you might force it into an unnatural position which can mess with the natural shape of your hair fibre.
