Do experiment. With your hair at its thickest and fullest, if ever you're going to get that Pixie Geldof inspired crop (pictured), it's now. A recent survey revealed that your hair peaks at 29 so make the most of it while you can. If you have gone snip-happy, reach for Michael Van Clarke's 3 More Inches range (from £17) to promote hair growth. What bad haircut?
Don't forget to detox. Just like your skin, your hair needs a break sometimes. So step away from the hairdryer/straightener/curling tongs* (*delete as appropriate) at least once a week and treat your hair to a little 'me' time
Try a weekly overnight treatment, like TIGI S-Factor Wonderful Tonight (£16.40).
