Want a subtle hair colour change but don't want to commit to something permanent? Book yourself in for the Colour Plus treatment, just launched at Mahogany salons. There are eight shades to choose from, which act like a transparent film over your own hair whether you want to take your flat blonde tresses a little honeyish, or rusty red hair more fiery. They last for around 8-12 shampoos, so we recommend you give one a try six months before your wedding to check you like the results, then another a the beginning of your wedding week for the freshest effect. Colour Plus Treatment, £43 for 2 hours, at Mahogany London, Oxford and Manchester, head to www.mahoganyhair.co.uk for more information.
