The best Secret Santa gifts are ones they can really use, and this Philosophy Cinnamon Sugared Apples Shampoo (£16) certainly fits the brief. In a cinnamon and sugared apple scent, it's classically Christmassy with a slight shimmer to boot. Over 2,500 people have rated it online with an overall score of over 4 out of 5 stars, so it's definitely a crowd pleaser.
