In the UK, weight loss medications are increasingly used to support health goals. Many people worry that these medications cause hair loss. The truth? Hair shedding is usually not a direct side effect of the medication itself.
Instead, it’s often linked to rapid weight loss and how the body responds.
Why Rapid Weight Loss Can Trigger Hair Loss
Hair loss related to weight loss is typically telogen effluvium, a temporary condition where more hair follicles than usual enter the resting phase. This happens due to stress on the body caused by sudden changes in diet, weight, or nutrient intake.
Main Causes:
- Calorie restriction: When the body lacks sufficient energy, it prioritises vital organs over hair growth.
- Nutrient deficiencies: Rapid weight loss can reduce intake or absorption of protein, iron, zinc, and essential vitamins.
- Hormonal changes: Weight fluctuations can affect thyroid function and sex hormones, influencing hair growth cycles.
Hair usually starts to regrow within 3–6 months once your body stabilises.
