Adele's hair style for the 2017 Grammy Awards was inspired by an ''[old] Hollywood icon'', according to beauty expert Chris Appleton.

The 28-year-old powerhouse's hair stylist for the star studded bash, which took place on Sunday (12.02.17) evening at the Staples Centre in Los Angeles, has revealed he pinned the vocalists tresses up into a modern chignon when she adorned the green Givenchy gown - one of three outfits she adorned on the evening - because he wanted the musician to have a ''classic Adele glamorous look'' with a ''modern finish''.

Speaking to PEOPLE about the flame-haired musician's aesthetic, he said: ''[Old] Hollywood icon but [in] 2017.

''I wanted it to have a classic Adele glamorous look, but I wanted it to have a modern finish. The look was effortless and glam, but I wanted it to have a polish to it. [A] glamorous finish, so the hair looked super glossy and healthy.

''I love it when Adele looks glamorous.''

Chris added extra volume to the 'Hello' hitmakers locks without using any kind of backcombing with a hair brush because he wanted to keep a ''looseness'' to her beauty look.

He explained: ''Because the look was very glam, I wanted to keep a looseness to it. At no point did I use a comb or a brush, which was an integral part of the look to keep it really natural. I didn't want it to look too stiff.''

''[The two French twists on either side of Adele's head] gives you that really nice volume at the back. And then I just textured out the curl to let the front fall out into wispy sections using a toothbrush and some hairspray to make it fun and natural.''

However, when Adele took to the stage to perform her '2015' hit single, which was recognised as Song of the Year at the music extravaganza, Chris wanted a ''beachy, undone'' style for the artist.

He explained: ''I'm all about change. Everybody knows 'Hello' and the beautiful hair she's got so I wanted to show it off with a tousled finish. I went for more of a beachy, undone, slightly wet-looking texture.

''The trick is, putting it up first. It gives amazing texture. Some people like their hair a couple days old, and it's great when you put your hair up because it gives it that few days old, rock and roll finish.''

And Chris twisted Adele's hair into a ''romantic'' topknot bun for tribute to the late music legend George Michael.

He explained: ''I wanted it to be romantic to complement the tribute. [It] worked perfectly.''
