Understanding hair structure and the stages of hair growth allows one to understand the ingredients and processes in hair maintenance that can support healthy hair & scalp.
HOW DOES THE HAIR GROW? THE GROWTH CYCLE
Hair growth can be explained via 3 stages: Anagen, Catagen & Telogen. The growth phase is the Anagen phase in which hair strands get longer. It can last anywhere from two to six years. The Catagen phase is a transition time when the hair fibre stops growing and detaches from the growth portion of the follicle. It lasts about two weeks. The Telogen phase is a dormant phase of the hair follicle and lasts anywhere from 1 to 4 months. At the end of this phase the hair follicle starts growing again and the Anagen phase commences. Hair grows about ~1.2cm per month. Hair fibre diameter changes as people age. Â It starts out thin and gets thicker as a person enters adulthood. Then it begins to get thinner and become more fine with advancing age. Maximum hair length changes too with older adults having generally shorter growing hair.
WHAT DOES HAIR LOOK LIKE? THE STRUCTURE
There are 3 main structures of hair: Cuticle, Cortex, and Medulla. The cuticle is the out layer of the hair and looks like tiles on a roof or scales. It is responsible for hair shine, smoothness, and ease of combing. Most hair products will interact with this layer. The cortex is the inner structure of the hair which is responsible for the fibre strength and flexibility and is mainly made of keratin. The medulla is the inner core of the hair fibre which is made of sugars and amino acids.
The shape of a hair fibre depends on the shape of its follicle.Â Hair gets pushed out of the head through a tiny hole. The more circular the hole, the straighter the fibre. The more elliptical the hole, the more curly the hair.
WHAT IS THE CHARGE OF YOUR HAIR? WHY IS THIS SO IMPORTANT?
The surface of hair (the cuticle) has a net negative charge. Especially when in contact with products that have a higher pH than ~3.7. The reason why this is important is that it allows us to choose the right ingredients that will work with the hair. Thatâ€™s why cationic ingredients (positively charged) are more substantive to hair.
