Tips To Select The Perfect Hair Length

There is no such thing as the PERFECT hair length. The length of your hair all depends on the different hair types or textures your hair type falls under. 

Straight Hair Length

Naturally, straight hair will always fall longer as it’s fully showing its true length when you go to measure the hair. There is no need to move where the hair falls naturally as you get the full length no matter where it falls. 

Wavy Hair Length

Wavy hair textures which lie between straight and curly will be a little harder to measure lengthwise, as you will lose some length with the wave in the hair. 

It is suggested to take the front part of your hair and pull it straight so you can measure it fully. You could also straighten your hair to achieve the straight length without losing the length with the wave. 

Curly Hair Length

Measuring curly hair is likely one of the hardest hair types to measure accurately as you naturally dont have the length showing with the curls. So you would need to pull the hair down straight to measure from the beginning to the end. 

It’s important to remember when measuring your hair length, it should be calculated from the top of your head to the bottom of your hair, as the hair is straight in line.

This way every time you check your hair length you can achieve accurate measurements to work out how much it has grown. 

Using a MEASURING TAPE is more than sufficient to measure your natural hair length. 

Be sure to measure from the same point each and every time you measure the length to keep the results accurate, this way you can work out if your hair is slowing down in growth more than usual then you can arrange a trim to help the health and growth of your hair.
