The 5.5cm rule reveals the best hair length for you

Have you always wanted to try a short cut, but afraid that short hair doesn’t suit you? Or, conversely, you think a bob or a pixie is right for you, but you can’t help but wonder: would long hair look better on me?

In fact, never let a simple math formula get in the way of your personal taste, especially if you’re comfortable with your current hair length. In that case, don’t change anything. But if curiosity is so strong and you’ve always wondered what is the most suitable hair length for you, now we have the answer.

How does the 5.5cm rule work for the perfect hairstyle?

If you are among those who are already planning the next makeover, but want to know which hair length suits you before the hairstylist gets to work, we offer you the solution to this dilemma. The optimal haircut for you can be calculated very simply. Yes, that’s right and mathematics comes to the rescue.

Those familiar with angles and numbers can breathe a sigh of relief. And for those who haven’t done math for a while, no problem. We are here for this. The optimal hair length depends on the angle of the jaw. We will now explain exactly how to apply the 5.5 cm rule with this knowledge.

Applying the 5.5 cm rule correctly: how to do it

The formula was developed by John Frieda hair product line experts to calculate the most harmonious hair length for each face shape. And you don’t need to go to the hairdresser, you can easily find out at home. All you need is a ruler, a pencil and a mirror.

Instructions for the 5.5cm rule for hair:

1. First, stand in front of the mirror.
2. Now take the pencil and place it horizontally under your chin.
3. This is where the ruler comes into play: place it at right angles to the pencil and push it up to earlobe height.
4. Now the math comes into play: just measure the distance from the earlobe to the stud vertically down.

But why is it called the 5.5 cm rule? It’s simple: if the distance measured in the last step is less than 5.5cm, the short haircut suits you well. Self exceeds 5.5cm, the longest hair are more suitable for you.

Short or long hair? What factors need to be considered in addition to the 5.5cm rule?

Of course, a mathematical formula doesn’t determine the hairstyle, but it might help you decide. Additionally, the shape of your face or the texture of your hair can also play a big part in determining which haircut is best for you. Therefore, we advise you to consult your hairdresser, regardless of what the ruler has shown.
