When the stress-regulating hormone—cortisol—is excessive in the body, it will mostly likely trigger a change in the 4 stages of the hair cycle. This, in turn, results in premature hair fall and thinning.
Hereditary-pattern baldness is another common cause of major hair loss. It is a natural condition caused by a specific combination of genetics, hormone levels, and the ageing process.
