Weight loss can bring a host of improvements to metabolic health, but for some people, it comes with an unexpected side effect: hair loss. In this article, Mary Dan Eades explains telogen effluvium, a temporary form of hair shedding that can follow significant weight loss, illness, surgery, pregnancy, or even a major positive change in diet and lifestyle. The process is rooted in the hair growth cycle, as metabolic stress can push more follicles than usual into a resting phase, leading to noticeable shedding a few months later.

The important distinction is that hair shedding after weight loss does not automatically mean your diet is deficient or that your new lifestyle is doing harm. In many cases, the follicles are already preparing to grow new hair, and normal hair density gradually returns over the following months. Understanding the physiology behind the process can prevent people from abandoning beneficial changes out of fear. Persistent hair loss, however, warrants further evaluation to rule out other causes.
