How Blonde is too Blonde? Can you take it too far?
So, what do colourists really think when you badger them to go blonder?

‘I don’t believe there is a rule on how blonde anyone should go, I tend to think of the hair condition first and then the client’s overall style,’ says Lamb (who incidentally couldn’t do a ‘bad’ blonde if she tried). ‘You can be as blonde as you want but only if your hair can take it. Over-processing your hair equals damage and damaged hair makes your colour looks dull, which again gives you that urge to want to be blonder. It’s your colourist’s responsibility to make sure they are not overlapping the colour as that will double process your hair. Your colourist will build up your blonde up to a point in order to give you the desired blonde but it’s all about knowing when to stop and not pushing it to breaking point…literally.’
To avoid being blighted by blonde blindness, Lamb advises keeping on top of your roots rather than dragging out your appointments which then means you’re left with having to overload your hair with foils and/or balayage. ‘A good pick-me-up for when you’re feeling low in between appointments is to go for my signature 12 foils technique which means just placing colour around the high points of your face. It’s the perfect way to lend a natural-looking boost of brightness.’Did I mention I’m seeing her tomorrow?
