There is an indirect link between belly fat and hair loss due to the hormone insulin-like growth factor (IGF-1), which is affected by insulin.IGF-1 increases blood flow to the root of the hair bulb, promoting hair growth and preventing hair loss.Excess belly fat can be a sign of an unhealthy lifestyle, leading to nutrient deficiencies and chronic stress, which can contribute to hair loss.Maintaining a healthy weight, eating a balanced diet, and managing stress levels can help promote healthy hair growth.
