Is Hair Loss After Weight Loss Normal? Causes, Risks, And Prevention


Hair loss after weight loss is a common concern. To understand it better, let’s look at causes, risks, and prevention.

Stress and nutrient deficiencies are two possible causes. Stress leads to telogen effluvium, where hair follicles enter a resting phase and shed. Nutrient deficiencies from rapid weight loss can also harm follicles.

To prevent or lessen hair loss, make mindful choices. Eat a balanced diet with proteins, fruits, veggies, and whole grains. Use gentle shampoos and avoid heat-style tools. Consider consulting a healthcare professional or dietitian before starting a weight-loss program, to get the right nutrients.

What Are The Causes Of Hair Loss After Weight Loss?

Hair loss after weight loss is common. Nutritional deficiencies, rapid weight loss, and hormonal imbalances can cause it. These disrupt the hair growth cycle and cause shedding.

Nutrition is key. With weight loss, the body may not get enough vitamins and minerals. This affects hair health and makes it thin or shed.

Rapid weight loss shocks the body and can lead to telogen effluvium. This causes more shedding for months.

Weight loss can also cause hormonal changes. These disrupt the natural hair growth cycle and cause thinning or loss.
