Niall is known for his bleach blonde hair but he has now gone to the dark side... sort of.
Over the years Niall has changed up his hair quite a bit. From completely blonde, to partially blonde, and more recently only the front bits lightened. And now, he has a solid brunette colour.
Sweet Niall has been working on his debut solo album over the past few months, and in December, made a string of appearances performing his debut solo single "This Town".
We can't wait till we hear more from Niall. Still a little unsure what look we love best though...
