The most common cause of hair loss is genetic, a condition known as androgenetic alopecia. This hereditary condition is progressive and causes hair follicles to shrink, producing thinner, finer hairs over time. Eventually, the follicle stops producing hair altogether. Hereditary hair loss occurs because of an inherited hormonal sensitivity passed down from either or both biological parents. For men, it’s often called male pattern baldness because it follows a pattern of loss at the temples and/or crown. For women, hair loss doesn’t always follow a recognizable pattern. It may present as a widening part, patchy hair loss or thinning all over. Rescue Hair 911
