Because Uncle Simon said he can't.
But it has now surfaced that Simon has told Niall Horan that there is no blinking way that he is going to dye his hair black.
A source told The Sun:
‘Niall was desperate to get rid of his blonde locks and go black just for an experiment, like loads of normal teens.
‘Luckily, he had the sense to ask Simon first because he knows how he works. He put in a text to him asking if he could change his hair colour.
‘Simon was straight back on to him with a short reply, “No way”. Simon still controls a lot about the band down to the finest detail.’
We think that is pretty unfair, because maybe Niall just wants to grow his hair out and dye it a dark and mysterious colour.
Well, to be honest he just really wants to put his hair back to the way it looked before the X Factor.
Well, whether this is true or not, we think Niall would look great whatever way he had his hair.
We don’t judge.
Anything’s cool with us.
