Hair loss can happen during rapid weight loss, including when using the Wegovy pill (oral semaglutide weight loss tablet). In most cases, it’s not the medicine directly ‘causing’ hair loss it’s the stress of fast fat loss, lower calorie intake, and low protein or nutrient intake. The best prevention plan is steady weight loss, high protein, iron and zinc awareness, and avoiding crash dieting.
Why Hair Loss Happens During Weight Loss
When your body loses weight quickly, it can shift more hairs into a resting phase (often called telogen effluvium). This is common after:
• Rapid weight loss
• Stress and poor sleep
• Low protein intake
• Low iron or low calorie intake

If you’re unsure, a clinician or dietitian can help set a realistic daily target.
When Hair Loss Needs Medical Advice
Speak to a clinician if:
• Hair loss is severe or sudden
• You have scalp irritation or patches
• You feel weak, dizzy, or unwell
• You’re losing weight extremely fast
Sometimes blood tests for iron, thyroid, vitamin D or B12 may be appropriate.
