Can losing a lot of weight make your hair fall out?

Rapid or extreme weight loss can cause temporary hair loss. This is because when the body is under stress, such as from drastically cutting calories or severely restricting food intake, it can go into survival mode and divert its energy to essential bodily functions, such as keeping the heart and lungs working. Nonessential functions, like hair growth, may be temporarily suspended as a result.

However, it's important to note that not everyone who loses weight will experience hair loss. Many factors can influence hair loss, including genetics, hormonal imbalances, certain medical conditions, and medications. If you're concerned about hair loss or notice a significant change in your hair's texture or thickness, it's best to consult with a healthcare professional to determine the cause and discuss potential treatment options.

In most cases, hair loss due to weight loss is temporary and will resolve once a healthy weight is restored and the body's nutrient stores are replenished. Eating a balanced diet that is rich in vitamins and minerals, such as iron, zinc, and biotin, can help support healthy hair growth.
