Long-term medical weight loss
Side Effect – Hair Loss
Hair Loss: Symptoms, Causes & Treatment
Hair loss is a common side effect experienced by some people taking GLP-1 medications (such as Wegovy and Mounjaro). GLP-1 medications work by reducing appetite and slowing down digestion. It is also an effect of reduced nutritional intake, as the body directs vital minerals and nutrition to more important organs, and is recognised by the body as stress or trauma.
Additional factors that could contribute:
- Ongoing stress, disrupts normal hair growth
- Reduced protein or nutrient intake
- Hormonal shifts
- Metabolic changes as your body adjusts to rapid weight loss
Symptoms of hair loss can include:
- Gradual thinning of hair
- Receding hairline
- Loosening of hair that leads to handfuls of hair coming out
- Thinner ponytail
Hair loss usually begins 2-4 months after weight loss starts and can continue for several months before improvements can be seen. Hair loss associated with GLP-1 medication is temporary and reversible.
- Dietary recommendations:
- Increase protein intake and try to aim for at least 1g of protein per kilogram of body weight per day or 100g of protein daily. Try and consume complete proteins like lean meats, fish, eggs, dairy, and legumes
- Focus on a balanced diet with plenty of fruits, vegetables, and other nutrient-rich foods to try and address potential deficiencies
- Supplements & Medical interventions
- Take multivitamin supplements regularly, especially if you are eating much less
- You can request blood tests through your GP to test for your iron, zinc, B12 and vitamin D levels
- Lifestyle Changes
- Manage your stress levels by trying to use stress reduction techniques like exercise or meditation
- Adapt gentle hair care by avoiding use of harsh chemicals and excessive heat when styling or drying. This can help reduce strain on hair follicles
- Hair growth is a gradual process and it is important to be patient while your body adjusts and responds over time
When to Seek Medical Advice
Losing hair can be upsetting for patients, as it is an important part of who they are.
- If hair loss is causing distress, your GP can help arrange some blood tests and help with some treatments that might help
- Counselling might help reduce stress and you may also be able to join a support group, or speak to other people in the same situation on online forums
Important Safety Advice
It is important to use GLP-1 medications safely and in line with clinical guidance. Side effects can often be managed effectively when identified early and addressed appropriately.
Maintaining open communication with your provider is key to ensuring safe and effective treatment.
Remember:
- Do not ignore persistent or worsening symptoms
- Do not increase your dose without clinical advice
- If you have had a break in treatment, restarting at a lower dose may reduce side effects
- Ensure your GP is informed of any new or unusual symptoms
