It's true that men are more likely to lose their hair than women, mostly due to male pattern baldness (more on that later).But thinning hair and hair loss are also common in women, and no less demoralizing. Reasons can range from the simple and temporary a vitamin deficiency to the more complex, like an underlying health condition
Some men have areas on the scalp that are very sensitive to the male sex hormones that circulate in men’s blood.The hormones make the hair follicles – from which hair grows – shrink. Eventually, they become so small that they cannot replace lost hairs. The follicles are still alive, but are no longer able to perform their task.
