Celebs love to tell us what beauty products they use - just check out their Tweets! But what do the experts think about their favourite products?

@Palomafaith: Has anyone tried superdust by L'Oréal? It's so bloody good? Instant BIG HAIR!
What the experts say: "I can see why this product got a great tweet from Paloma. It is every woman's dream to have full hair and this product is great for creating instant oomph," says celebrity make-up artist Lee Pycroft (@sarah8leesworld). "A touch of powder sprinkled into the roots of hair is all it takes to add volume to limp locks."
