Ever wondered just why your hair won't grow past a certain length?
Or why it's curly?
Or what it's made up of?Hopefully my new series of posts will help to answer some questions. As a self-confessed hair geek I love exploring the science of our hair, and really getting to the root (see what I did there) of what makes our hair, well, our hair.
First up, it's the structure. This is one of the first things I learnt (after A LOT) of health and safety, when I was training for my Hairdressing NVQ. Each strand of hair is made up of three primary layers, the cuticle - which most of you have heard of, the cortex, and the medulla.
