Celebrities by the dozens are today seen lopping off their long locks every day, and instigating a normal woman to embrace the change. But the A-list themselves can’t always pull off a bob.

Therefore, before heading to the salon with a photograph of Mary Quant, note the latest theory for when to chop and when to stop – the foolproof 2.25-inch rule.

Do you wanna know whether you’d look good with short hair? Or learn how to tell if longer hair is a better match for your face?

Hair professionals at Color Wow – the range of products for coloured hair – have come up with a fool proof way to get the short answer to these questions.

THE 2.25′ (5.5cm) RULE.

To find out the right hair length for your face, you don’t need to consult with a stylist, embark on a never-ending research, or pull back your hair, squint your eyes and try to imagine your face with a short hair style.

The only essentials you’ll need for it is a ruler and a pencil, and The 2.25-inch (5.5cm) Rule.

International Training Director of Color Wow and Senior Stylist at John Frieda Salons UK, Giles Robinson, says: ‘It’s all about the angles. The Rule was created by John Frieda, and it is a fool-proof guide for hair stylists to use so they can tailor the cut to make the length as flattering as possible to the face shape.

John after years of studying faces has deduced an exact, easy to understand measurement that clearly indicates whether a face is suited to long or short hair.


Procure a ruler and a pencil. Now, place the pencil under your chin horizontally. Then place the ruler under your ear, vertically. The intersection of the pencil and ruler indicates a measurement.

A measurement under 2.25 inches indicate that like Halle Berry and Audrey Hepburn, your face is made for short hair. And if it’s more than that length, like Kim Kardashian and Sarah Jessica Parker, then long hair will be the most flattering choice.

So, before going for short crop or a long hairstyle, just remember The 2.25′ Rule… if the distance from the bottom of your ear to your chin is greater than 2.25′, consider longer haircuts. But, if that distance is less than 2.25′, you have a face suited to short hair, even a super-short pixie cut.

Giles says: ‘Two A-list women that suit the chop are Katie Holmes, whose shorter jawline is perfect for a pixie or fringed bob as seen at the Met Ball earlier this month. DJ Quintero at the John Frieda Salon in NYC created this flattering style for her, this cropped cut really makes her features pop – it’s spot on.

‘Although she looks gorgeous ‘old world Hollywood’ with long hair, Emma Stone is another celebrity whose features are enhanced by this cut she really looks amazing with a bob.’

Giles further adds Jessica Alba got it wrong. The bob or crop doesn’t fit well to her longer jawline, instead long hair is really more flattering. ‘The same is true for Kim Kardashian, she recently went for the lob but she suits longer flowing locks that balance and frame her longer heart shaped jawline,’ he says.
