Suki Waterhouse’s beauty rules

Model-turned-actress Suki Waterhouse on her unusual hair trick and why goat poo rules OK (sort of).

I once accidentally shaved off one of my eyebrows! It was in a crazy attempt to tidy them up when I didn’t have any tweezers. Naturally, my brows can be quite feral, so I look a bit happier when the hairs are brushed up. I tend to use any eyebrow gel I can get my hands on.

I’m more comfortable as a blonde. I went brunette for a film and I can confirm that dyeing your hair is both liberating and distressing. The good thing about having dark hair is that you can go without washing it for a few days, which is always a plus. When I’m blonde I’ll throw on egg whites, mayo and yoghurt to keep it conditioned and, douse it in argan oil overnight.

I cut my own fringe and have take scissors to it late at night when I can’t sleep. It isn’t looking too great right now, so I’m growing it out and starting again. I use hairstylist Neil Moodie’s products and never blow-dry my hair. I prefer the way it looks after washing it, then sticking my head out of the car window. A quick brush-through and I’m good to go.

I have a HydraFacial with Chantelle at the Waterhouse Young Clinic in London. They have a machine that shows you where there’s sun damage and how the skin looks beneath the surface. After seeing the effects of UV rays, you will want to wear sunscreen. My skin goes through so many make-up changes and this facial puts the bounce back into it.

I love to do a headstand when I’m stressed. It stimulates the pituitary gland, which calms the mind. And the rush of blood to my face nourishes my skin.

I need to be healthy for Fashion Week. The best thing I have ever come across for my immune system is the Vitamin C sachets from Altrient. They taste like goat poo, but absolutely rule.

Red-carpet ready? My favourite look was for the Met Ball in 2014. I’ve always been afraid of a red lip, but make-up artist Wendy Rowe convinced me to go with Burberry Kisses in Union Red. I loved it. For a red carpet event I’ll always use Burberry Fresh Glow Foundation; it has the most gorgeous sheen to it. When it comes to my hair, I like a ‘do’ that doesn’t fall in my face, so I can forget about it.

When I’m flying, I usually just collapse and fall asleep for 11 hours straight without drinking water or even taking my make-up off. I’m really not very good at looking after myself on a flight. If, however, I’m being good, I’ll put on some vitamin C serum and slather myself in HealGel – it’s my greatest skin weapon.

I’m a vocal boxer! Boxing is awesome, because you can be aggressive and make strange grunting noises, and it’s OK. I do weight training to keep my body toned, but I’m also a strong believer in yoga and its powers to lengthen us out.

I love juice! The Juice Well in London is an absolute juice mecca. When I’m in LA, I go to Earth Bar. They even have a vitamin IV drip – talk about a hangover cure.

Lou Duillon changed my life. I saw her once at a gig in Paris. It wasn’t even what she was wearing; it was just the whole thing, her beautiful vibe. I think it’s all about finding a style that expresses the uniqueness everyone possesses; that feeling that you’re putting it out there.
