Low-calorie diets and rapid weight loss can trigger shedding. How to keep your hair healthy while you lose weight.

The short answer
Rapid weight loss and low-calorie diets can push hair into a shedding phase called telogen effluvium. Lose weight gradually, eat enough protein, iron and zinc, and support your scalp. Shedding is usually temporary.
Weight Loss Shouldn’t Cost You Your Hair
We hear it all the time in January: “New Year, New You!” It’s the rallying cry of the weight-loss industry, a reminder that many people use the new year as an opportunity for change. While improving your diet and lifestyle is commendable, one surprising side effect of rapid weight loss can be hair loss. Here’s why it happens and how you can prevent it while reaching your goals.
Low-Calorie Diets and Hair Loss: What’s the Connection?
Very low-calorie diets—typically under 1,000 calories per day—can lead to quick weight loss, but they’re also hard on your body. When your body lacks sufficient calories, hair follicles may not receive enough energy to support hair growth, resulting in thinning or brittle hair. This condition is often temporary but can be frustrating.
Another contributor is telogen effluvium, a form of hair loss caused by stress or abrupt body changes:
Dieting can trigger this condition.
You might notice hair loss three to four months after starting a weight-loss regimen.
Hair usually grows back within three to six months as your body adjusts.
How to Prevent Hair Thinning During Weight Loss
Avoid extreme measures and focus on a balanced approach to dieting:
Choose sustainable changes: Gradual weight loss is kinder to your body and less likely to stress your hair follicles.
Focus on macronutrients: Ensure your meals include proteins, healthy fats, and carbohydrates to support overall health and hair strength.
Add supplements: A daily multivitamin with minerals can help make up for any nutrient gaps caused by calorie reduction.
Don’t skimp on protein: Hair is made of keratin, a protein. Include foods like lean meats, eggs, and beans in your diet.
Include biotin-rich foods: Biotin is vital for hair health. Add biotin-rich foods like salmon and nuts to your meals.
Be mindful of zinc: Zinc deficiencies can lead to brittle hair. Foods like pumpkin seeds, spinach, and whole grains can help.
