The singer won this year's contest with her track 'Euphoria' for Sweden on Saturday (May 26), gathering points from all 41 nations apart from Italy.
Speaking about her win, she told BBC Breakfast: "I think people liked my performance because it's not usual for Eurovision. Normally it's maxed, and I had a message.
"Normally you have to look a certain way, but my hair was messy. Sometimes it's good just to narrow it down."
Loreen revealed that her winning routine was tough, but that she was able to "focus" despite accidentally swallowing the fake snow on stage.
"It's all about focus, there's so many important parts in this performance. I'm standing on the podium, it's one metre high and with all the cameras. I have to put out everything and focus.
"I swallowed some snow. But it's like that when we create art."
When asked why Sweden won, while Norway finished last despite sharing a songwriter, she said: "I don't think it only has to do with the song.
"It has to do with the artist and how you present it. Those are different parts which are as important to the song."
Loreen also praised UK entry Engelbert Humperdinck, who finished second from last for his performance of 'Love Will Set You Free'.
She added: "I liked the song, and I like his voice. He has a beautiful voice."
'Euphoria' is expected to reach the UK top ten singles chart following Loreen's win on Saturday.
