Why can Weight Loss Cause Hair Loss?

Weight loss can cause hair loss due to a few reasons.

First, if you lose weight rapidly or if you follow an extremely low-calorie diet, your body may not be getting the nutrients it needs to support healthy hair growth. Your hair requires essential nutrients like protein, vitamins, and minerals to grow and stay healthy. So, if you are not getting enough of these nutrients due to a restrictive diet, it can lead to hair loss.

Secondly, weight loss can be a stressful experience for the body, and stress is known to be a common cause of hair loss. The stress of weight loss can lead to a condition called telogen effluvium, where more hairs than usual enter the resting phase of the hair growth cycle and eventually fall out. This type of hair loss is usually temporary and resolves on its own once the body adjusts to the weight loss.

Lastly, weight loss can also lead to hormonal changes in the body that can affect hair growth. For example, rapid weight loss can cause a drop in estrogen levels, which can lead to hair loss in some women.

It is essential to ensure that you are losing weight in a healthy way and that you are getting the necessary nutrients to support healthy hair growth. If you experience significant hair loss during weight loss, it is best to consult a doctor or a registered dietitian to identify the underlying cause and develop a plan to address it.
