Doctor reveals finger measurements may predict male baldness risk

A US doctor has identified a method to predict male baldness using finger measurements. Dr. Joe Whittington explains that the ratio of the ring finger to the index finger, known as the 2D:4D ratio, can indicate hair loss risk. Research shows that men with a lower 2D:4D ratio, where the ring finger is longer, are nearly six times more likely to experience hair loss. This is linked to prenatal testosterone exposure, which increases sensitivity to hormones that affect hair follicles. For those experiencing hair loss, treatments include medications like minoxidil, hair transplants, and FDA-approved laser therapy. These options aim to address various causes of hair loss and improve hair density.
