The advice my hairdressing friend gave me was to have a couple of washes with a shampoo that strips your hair. I used original vosene but washing up liquid would do (followed by a good conditioner). Alternatively, go for a 'clarifying' shampoo which removes build up as these work well too! Pantene does one and so does Neutrogena. Good luck!
