Weight loss injections such as GLP-1 agonists (Ozempic®, Wegovy®, Mounjaro®) are becoming increasingly popular for achieving quick, sustainable weight loss. However, many people report hair loss as a side effect — which can be distressing.
At DermAttract, a doctor-led aesthetic clinic based in Reigate and Redhill, Surrey, we understand how important it is to maintain healthy hair while pursuing your weight loss goals. Here’s our evidence-based guide to minimising hair loss during weight loss injections, so you can achieve your desired results without compromising your hair health.
Understanding Hair Loss During Weight Loss
Hair loss during weight loss treatment often results from a condition called telogen effluvium, where hair follicles enter a resting phase due to physical or metabolic stress. Rapid weight loss and calorie restriction can trigger this process — research suggests up to 30% of people experience this type of shedding after significant weight changes.
Nutritional deficiencies also play a key role. Studies show 38% of individuals with thinning hair have a deficiency in iron or essential nutrients. Maintaining good nutrition is therefore crucial to support healthy hair growth while on GLP-1 injections.
Nutritional Considerations
1. Prioritise a Balanced, Protein-Rich Diet
Hair is primarily made of keratin, a protein. Adequate protein intake helps strengthen and rebuild hair fibres. Include lean protein sources like chicken, fish, eggs, legumes, and nuts. Aim for at least 50g of protein daily, particularly when losing weight.
2. Include Key Vitamins and Minerals
Hair follicles need a balance of micronutrients to grow optimally. Focus on:
Vitamins A, C, D, E, and B-complex
Minerals like zinc and iron
Add leafy greens, berries, and nuts to your daily meals to enhance your nutrient profile and support follicle function.
Hydration Matters
Dehydration can make hair brittle and prone to breakage. Aim for at least 2 litres of water daily.
Hydration Tips:
Carry a reusable water bottle to sip throughout the day.
Infuse your water with fruit or herbs like lemon or mint for flavour and added antioxidants.
Stress Management
Weight loss journeys can be stressful — and stress is a major trigger for hair loss. Studies show that up to 50% of individuals under chronic stress experience increased shedding.
Simple stress-reduction strategies:
Mindfulness or meditation for 10 minutes daily
Regular exercise, such as walking or yoga
Adequate sleep (7–9 hours per night)
Lowering cortisol not only helps your mind but also supports the natural hair cycle.
Hair Care Practices
1. Gentle Hair Care
Avoid harsh shampoos or overuse of heat styling tools.
Use sulfate-free shampoos to retain natural oils.
Let your hair air dry when possible.
2. Maintain Scalp Health
A healthy scalp encourages better hair growth.
Perform scalp massages for a few minutes daily to stimulate blood flow.
Try essential oils such as rosemary or peppermint mixed with a carrier oil to enhance circulation.
Medical Consultation & Advanced Treatments
If you’re noticing significant hair loss during weight loss injections, speak with a healthcare professional or aesthetic doctor.
At DermAttract, we offer treatments to support scalp health and stimulate regrowth, including:
Polynucleotides – an innovative injectable treatment using purified DNA fragments to rejuvenate the scalp and encourage new hair growth.
Nutritional and lifestyle reviews to address underlying deficiencies.
Lifestyle Adjustments
Avoid crash diets or severe calorie restriction. Research consistently shows gradual weight loss (1–2 lbs per week) leads to better long-term results and reduces hair shedding risk.
Your Path to Healthier Hair
Hair loss during weight loss injections doesn’t have to be inevitable. By focusing on nutrition, hydration, stress control, gentle care, and professional guidance, you can protect your hair health while achieving your body goals.
