The One Direction star is considering ditching his famous blond locks in favour of a darker 'do.
'My natural hair colour is nearly black,' Niall, 18, tells Channel 955.
'So I'm thinking about heading towards that kind of thing, because I've been doing this for a while.'
But it's not quite that simple for Niall - boss Simon Cowell, 52, is reported to have opposed his plans.
'Niall put in a text to him asking if he could change his hair colour,' a source tells The Sun.
'Simon was straight back on to him with a short reply: "No way."'
