The Disney girls did it first when Bella Thorne and Debby Ryan both added a red tint to their natural hair colours. Ariel Winter followed suit, before going blonde, and then a slew of other celebs jumped on the bandwagon. The trick is to just a red or copper tint to your natural hair colour to warm it up. As with going lighter, this is best left to the professionals to help decide whether this look will suit your skin tone. If you want to try this at home, stick to non-permanent formulas with the words “golden” or “auburn” for the tiniest hint of red before committing to this trend. This look is perfect for trying during the colder months as it looks amazing paired with a darker wardrobe. Will you dare to take the plunge?
