When you're trying to get your hair to do something it doesn't naturally do, you need to give it a helping hand. Don't expect a tong or ghd styler to work miracles on its own. Use some product! Firstly, for hot tools you'll need a heat protector. Then choose a holding product that will give added oomph. If you hair has a natural wave, a curl-enhancing mousse will help to provide hold and lasting power. But if you have straight hair, you'll need something really powerful. Old-fashioned setting lotion is like liquid hair spray. It's not the most glamorous product, but it will definitely help to hold a curl.
