GLP-1s don’t directly cause hair loss. Instead, it can be a temporary side effect of rapid weight loss caused by taking the drug.

Rapid weight loss can sometimes lead to nutritional deficiencies and hormonal imbalances, which can put stress on the body and lead to hair shedding or thinning. This is medically referred to as telogen effluvium.

While hair loss from GLP-1s is typically temporary, it may take some time for your hair to grow back.

If you’re experiencing hair loss, it can be helpful to:

  • Ensure adequate nutrition: As GLP-1s can cause rapid weight loss, it’s essential to eat a balanced diet to ensure you are still getting enough nutrients. This can help reduce any deficiencies that can worsen hair loss.
  • Be gentle with your hair: If you’re experiencing hair shedding or thinning, it’s important to be gentle with your hair and avoid harsh brushing and washing.
  • Manage any stress: Stress can often worsen hair loss. It can be helpful to manage stress through techniques such as ensuring you get enough sleep and exercise and eating a balanced diet.
  • Be patient: Hair loss or thinning from GLP-1s is usually temporary and will resolve over time.

If you are concerned about your hair loss or thinning, it’s important to speak with a healthcare professional. They can determine if your hair loss is a result of the medication you are taking or an underlying condition. They can suggest whether a change in medication may be suitable or discuss other options with you.
