Action plan: For hair, try the Apple Cider Cleansing Rinse by Frederic Fekkai, £13; Philip B products are great for damaged hair - try the Deep-Condition Creme Rinse, £21, left (both from Space NK, 0870 169 9999). Leave your nails varnish-free for several days. Massage daily with avocado or wheatgerm oil for a week, and avoid varnish removers that contain acetate. Alternatively, take a herbal supplement containing mineral-rich nettles such as Napiers' Nettle Blend (£12.55 for 200ml, www.napiers.net).
