The measurement runs from the bottom of the ear to the bottom of the chin. To measure yourself, place a pen or pencil horizontally under your chin (so that it sticks out on either side).
The 5.5 Centimetre Rule
One of the most famous rules in the beauty industry is the 5.5 cm rule, which says that the best length of hair is determined by the angle of the jawbone. The measurement runs from the bottom of the ear to the bottom of the chin. To measure yourself, place a pen or pencil horizontally under your chin (so that it sticks out on either side).
Next, grab a ruler and place it vertically under your ear (so that the top of the ruler is touching the bottom of your earlobe). Now, see where the pen or pencil meets the ruler. If it’s less than 5.5 centimetres, then a short hairstyle is best. If it’s more than 5.5 centimetres, then you should go with longer hair.
Short Face or Long Face
The rule above ties into this one, but it’s not a direct correlation. Some women with longer faces might not have a jawline longer than 5.5 centimetres, but will still look better with longer hair. The same applies for women with shorter faces (shorter hair suits better in most instances).
Face Width Matters, Too
It’s not just a question of how long your face is. A hairdresser in London will be able to judge what sort of length will be right for you based on the width of your face, as well as the length. Wider faces are better suited to longer hair, as it makes your face look longer and slimmer. Likewise, a narrower, longer face might be better suited to shorter hair, particularly if you want to create the illusion that your face is shorter or wider than it is.
Personal Preference and Experimentation
While the tips above may help you decide whether you’re better suited for short hair or long hair, remember that it’s your hair. You can do what you want with it. Play around with different styles. Experiment a bit. Get creative. There’s no hard and fast rule about what type of hairstyle is best for an individual person, simply because we’re all different. If you have large eyes and a narrow face, you might find that short hair is a great way to accentuate that feature even though longer hair would be the general recommendation.
Ultimately, your hairstyle should be more of an expression of your personality and passions than it should be about fashion or what’s popular with celebrities. It’s your hair. It should be about you.
Your Hairdresser in London
Of course, a great deal of the success (or lack thereof) with your hair cut rests on the quality of the hairdresser in London that you choose to work with. Look at before and after photos of past clients to see what they’re capable of creating. You should also consider the experience offered by the hairdresser as a whole – is it an “in and out” shop, or do they go the extra mile to create a unique experience that goes far beyond merely having your hair cut and styled?
