Losing weight with GLP-1 injections such as semaglutide (Wegovy® or Ozempic®) or tirzepatide (Mounjaro®) can be a game-changer for many. However, rapid weight loss or reduced nutrient intake may sometimes lead to unwanted side effects like hair thinning or fatigue. At Weight Medics, we believe in supporting your weight loss journey holistically—starting with the right nutritional support.
Why Nutrition Matters During GLP-1 Weight Loss Treatments
GLP-1 medications are designed to suppress appetite and support sustainable weight loss, but they can also reduce your intake of vital nutrients. Nutrient deficiencies during weight loss may affect your skin, hair, energy levels, and overall wellbeing.
That’s why we recommend a balanced, nutrient-dense diet and targeted supplementation as part of your medical weight loss plan.
Essential Nutrients for Hair Health and Whole-Body Wellness
To help maintain strong, healthy hair and support your body throughout your weight loss programme, focus on the following key nutrients:
- Protein – Vital for producing keratin, the building block of healthy hair. Include lean meats, fish, eggs, dairy, and plant-based proteins.
- Biotin (Vitamin B7) – Supports hair growth and scalp health. Found in nuts, seeds, legumes, and fortified foods.
- Omega-3 Fatty Acids – Help reduce inflammation and keep the scalp hydrated. Look to oily fish, flaxseeds, and walnuts.
- Iron & Zinc – Support healthy hair follicles and immune function. Found in red meat, poultry, beans, and spinach.
- Vitamin D – Plays a role in the hair growth cycle and supports immunity. Get it through safe sun exposure and fortified foods.
How GLP-1 Users Can Stay Nourished
GLP-1 receptor agonists can lead to smaller meals and less frequent eating, making it harder to meet daily nutritional needs. At Weight Medics, we recommend pairing your treatment with high-quality supplements and expert dietary guidance to ensure your body stays nourished while the pounds come off.
Our medical team can provide personalised advice on supplements that align with your GLP-1 treatment plan, helping you avoid deficiencies and feel your best throughout your journey.

Does rapid weight loss cause hair loss?
Rapid weight loss might cause telogen effluvium. When your body suffers physiological stress (such as a large calorie deficit or rapid weight loss), more hair follicles enter the resting (shedding) phase. This transient loss normally occurs a few months following a rapid weight shift.
Can GLP-1 medications like semaglutide or tirzepatide lead to hair thinning?
Semaglutide and tirzepatide do not harm hair follicles. They depress appetite, which may lower calorie and nutrient intake and cause hair thinning. This can cause telogen effluvium with rapid weight loss. Some people on these drugs experience hair thinning due to weight loss and vitamin deficiency, not the drug.
What nutrients are essential to prevent hair loss during weight loss?
Focus on hair growth and follicle function nutrition to lose weight and improve hair health.
Getting enough of them through food and supplements can reduce weight loss and hair loss.
How much protein should I eat to maintain healthy hair while dieting?
When dieting, many doctors recommend 1.0–1.2 g of protein per kilogram of body weight per day to sustain muscle and hair health. For instance, a 70 kg person should aim for 70-84 g of protein per day. Lean meats, fish, eggs, dairy, legumes, nuts, and seeds are good.
Is hair loss from weight loss temporary or permanent?
In most cases, hair loss linked to weight loss, including that seen with GLP-1 medications, is temporary. This type of shedding (telogen effluvium) typically resolves once your body adapts, nutrient intake improves, and weight stabilises, often within several months. There’s no strong evidence that semaglutide, tirzepatide, or other GLP-1s cause permanent hair loss when used appropriately.
