Ella Henderson looked fantastic again on the X Factor this weekend, and we asked the X Factor's hair stylist, Jamie Stevens, to give us the low down on her waterfall braid.

Jamie says: “With Ella, it’s all about keeping her look young and fresh, whilst working with on-trend looks such as plaiting and braiding, which has been all the catwalks for this Autumn/Winter season.”

To get her look:
1. We blow-dried the hair with TRESemme’s Weightless Volumizing Mousse which was applied onto damp hair and blow-dried in with a round brush for plenty of volume and hold!

Earlier today we brought you a step-by-step guide to recreating Ella Henderson's amazing retro make-up look from Sunday night's X Factor. Now, X Factor's official hair stylist Jamie Stevens explains exactly how to recreate Ella’s amazing hair look.

To begin, put a low side parting into the hair & blow dry, I used TRESemme’s Weightless Volumizing Mousse & a medium round brush.

She's not shy about trying new things but we were surprised when we saw the pic Ke$ha tweeted of her new hairdo.

She's had the sides shaved before but now she's gone one step further and got studs glued onto the side. She tweeted the pic with a short and simple statement: "Is happening"

"For the final show, we went for simpler hair. We gave all four girls curly hair to start so it could have a natural progression from curly to a softer curl and then a wave as it dropped."

Here's Jamie's step-by-step guide:
