Can Weight Loss Trigger Shedding?
The Short Answer: Yes, rapid weight loss is a major trigger for hair shedding. When the body perceives a sudden calorie deficit or protein shortage, it shifts energy away from "non-essential" tissues (like hair) to support vital organs. This condition is called Acute Telogen Effluvium and usually appears 3 to 6 months after starting a restrictive diet.
Why Diets Damage Hair
Hair is made almost entirely of Keratin (protein). If you are on a restrictive diet (like Keto, Intermittent Fasting, or using weight-loss medications like Ozempic), you may not be consuming enough amino acids to sustain hair production.
Furthermore, rapid weight loss depletes stored iron (Ferritin). If Ferritin levels drop below a certain threshold, the hair growth cycle stops immediately.
Prevention Strategy: If you are planning a diet, "bridge the gap" with a supplement. Viviscal PRO is ideal for dieters because it provides a concentrated dose of AminoMar™ (Marine Protein) directly to the follicle, ensuring hair grows even while you cut calories.
Common Questions About Diet & Hair
Will the hair grow back after weight loss?
Yes, once your weight stabilizes and your nutritional intake normalizes, the shedding will stop. However, it can take 6 months to a year for the volume to return.
Do weight loss drugs (Ozempic/Wegovy) cause hair loss?
The drugs themselves do not cause hair loss; the rapid weight loss they induce does. The faster you lose weight, the higher the shock to the system, and the more likely you are to shed.
