The most widespread cause of progressive hair loss is hereditary, taking on various names such as male-pattern baldness, female-pattern baldness and androgenetic alopecia. Other causes range from lifestyle habits and hormonal imbalances, to stress and nutritional deficiencies, according to the American Academy of Dermatology.
Common characteristics of Progressive Hair Loss include:
- Balding on top and crown of scalp
- Hair thinning
- Widening of center hair part
When hair follicles become smaller and produce shorter, thinner, more brittle hairs, it can eventually lead to the disappearance of those follicles altogether.
