So you want to know how much hair grows in a month? Well let’s first look at what hair is and how it grows.
The Cuticle, cortex and medulla are the 3 main layers of the hair. Cuticle is the outer layer of the hair and it is thin and colorless. The cuticle is responsible for offering protection to the cortex which is the thicker part of the hair strand. The cortex contains melanin which is the part of the hair strand that is responsible for determining the color of the hair. The color of the hair will depend on the kind of melanin one has out of two kinds which are; eumelanin and pheomelanin. Eumelanin is the kind of melanin that develops black hair and brown hair. The people who have black hair or brown hair have eumalanin which those with reddish hair have pheomelanin which is the kind of melanin responsible for reddish hair. Those people with blonde hair are a result of melanin being low in their hair. Gray hair due to lack of melanin and this is caused by aging or even illnesses and high stress levels. The medulla is responsible for giving the hair the different shades when it is hit by light. Medulla reflects light and this is why hair will look different in light than when one is under shade. Cortex determine the shape of the hair, straight-cortex makes the hair straight but when the cortex is oval shaped in the mid section, most probably you’ll have a curly hair.
Having said this about what hair is formed of, we can know look at how hair grows. Hair growth happens in 3 phases. These are Catagen Anagen,and Telogen. Anagen is the kind of growth that takes place between the longest periods of between two to eight years in someone’s life. During this phase, the growth cells which are in the papilla divide and develop the hair shaft which then becomes keratinized while it pops out of the follicle into the pore. During this time, the follicle also does grow deeper to try to get into the dermis where it gets nourishment from the blood. This determines the difference between the people who have long hair and those who have short hair. The people who have longer hair than others have a longer anagen period which enable them grow long hair while those who have short hair have a shorter anagen period. Catagen is the period that follows anagen period. This period lasts about two to four weeks only. In this period, the hair stops growing and the follicle are degraded. However, the hair does not fall. Telogen period is where the hair does not show growth at all but remains attached to the follicle.
