Short hair is the undeniable hair trend of 2020.
All our favourite celebrities have been opting for lobs and bobs - and giving us the ultimate hair envy in the process.
Don't believe us? Just look at the Golden Globes red carpet (the last red carpet in living memory) you couldn't move for short hair.
And now that we're stuck at home, it's the perfect excuse to switch up your style by grabbing some scissors and giving your hair the trim it deserves. However, it's not that easy is it? The thought of chopping off your hair can be extremely daunting, especially if you're used to having long hair.
You'll question what you would look like with short hair, if you could pull off daring pixies or trendy shags, or if you'd even know how to style a chin scraping bob. If that's the case for you, stop stressing.
We have found a genius trick that will help you find out whether or not a bob will look good on you. It's merely a simple case of maths and measuring your face. Fear not: It's not complicated and traumatising as it sounds; all you have to do is follow the simple instructions below:
The 5.5-Centimeter Rule
Discovered by hair icon John Frieda, the rule is simply this:
1. Take a pencil and place it under your chin.
2. Then place a ruler under your ear.
3. Take the measurement from where the pencil and the ruler meet.
4. If it's less than 5.5 centimetres, short hair is a go. If not, you should consider sticking to a longer length. Easy, no?
Not sure why this works? Us either but Giles Robinson from John Frieda told Glamour, this is because the key factor in whether a short hairstyle will suit you relies on the angle of your jawbone, and not your face shape.
And she's not wrong. It works well with Michelle Williams and Kim Kardashian (see below), and when you think of other obvious examples such as Audrey Hepburn next to Sarah Jessica Parker it becomes crystal clear.
That said, there's also a strong case for sacking all this off and just getting the hairstyle you want anyway, right?
