Nour Mansour experienced dramatic weight loss after starting Mounjaro, dropping from a size 18 to a size 8 in under seven months. However, she soon noticed severe hair loss, a side effect that has affected many users of the medication. Experts say the hair shedding is not directly caused by the drug itself, but rather by rapid weight loss and nutritional deficiencies that can result from reduced appetite and dietary changes.

Medical specialists recommend that anyone experiencing hair loss after weight-loss treatments should consider blood tests to check for deficiencies in key nutrients such as iron, vitamin B12, folate, zinc, and vitamin D. Improving diet and taking supplements can help reverse the problem, and most people see their hair regrow once their nutritional needs are met. Slowing the pace of weight loss and focusing on balanced nutrition are essential steps to minimise damage and support recovery.
