What causes people to lose hair ? Most cases of hair loss are caused by genetics.  Those with pattern baldness have DNA code sequences which will result in weaker protein receptors on the hair follicles.  This makes them more likely to suffer from damage caused by DHT.  DHT will cause these hair structures to become less able to absorb normal amounts of nutrition from the blood stream.  As a result, the follicles miniaturize.

Researchers are also learning that a prostaglandin called PGD2 is found abundantly on the scalps of men with pattern baldness. This compound is believed to also facilitate hair loss.

Genetic predispositions can interact with environmental variables which can either speed up the rate of loss or slow it down.  Heavy  smoking and alcohol consumption as well as environmental pollutants can exacerbate shedding and thinning . Stress which leads to physiological effects (e.g. poor sleep, diet etc.) can also lead to significant hair loss

Aside from genetics, there are other contributing factors.  Side effects from many forms of prescription medications can increase the rate at which hairs enter the telegen effluvium phase.  Overactive or underactive thyroid conditions can also lead to rapid hair loss.  Also extensions and tight hair styling practices can also lead to balding through follicular damage
