Alopecia can be categorized by types; there are different types of hair loss with different specific causes behind it. But the common causes of hair loss ranges from inherited factors, diseases, stress, medicines, injury to the scalp, aging, nutrition and hair care.


  • Inherited hair loss: The medical term for this type of hair loss is androgenetic alopecia. The cause behind this type is genetics. A person inherits the tendency to lose hair from either or both of the parents. This type of hair loss is also known as male pattern baldness and female pattern baldness. In this type of hair loss, your genes act as a stimulant to a class of hormones called androgens (including testosterone), which causes hair follicles to shrink. The shrinking follicles are unable to grow hair at normal pace and quality causing baldness. While man develop baldness in the crown or as receding hairline, women have an overall thinning of the hair.
