Does Dieting Cause Hair Loss?

In our pursuit of health and the ideal body image, many of us have faced the challenge of dieting. Restricting calories and modifying our food intake is a common strategy. However, an often unexpected side effect emerges a few months into these dietary changes: hair loss. This phenomenon is not localized to a specific area but can occur across the entire scalp. So, could dieting be the culprit behind hair loss?

The Link Between Dieting and Hair Loss

Hair loss associated with dieting is typically observed after periods of fasting or when the diet lacks sufficient nutrients. This can also be exacerbated by excessive exercise, which introduces additional stress to the body. Our body hosts rapidly dividing cells, notably in our skin, internal organs, and notably, our hair and nails. These cells require a constant supply of nutrients to function and regenerate.

During dieting, especially when intake of essential nutrients like proteins is inadequate, the body may prioritize vital organs over hair follicles, leading to hair loss. This mirrors the effects seen during chemotherapy, where rapidly dividing cells are targeted, resulting in hair loss among other side effects.

Nutritional Deficiencies and Hair Loss

A significant factor in diet-induced hair loss is nutritional deficiency. The human body requires a variety of nutrients to sustain hair growth, including proteins, vitamins, and minerals. When the diet lacks these essential components, hair growth can be adversely affected. Proteins are particularly crucial since they make up the primary structure of hair. Without adequate protein, the body cannot effectively replace shed hair, leading to noticeable hair loss.

Strategies for Healthy Dieting Without Hair Loss

To avoid hair loss while dieting, a gradual, balanced approach to weight loss is recommended. Rather than adopting extreme diets that promise rapid results, it's healthier to aim for a modest weight reduction, adjusting caloric intake and exercise levels sensibly. High-calorie foods, desserts, and alcoholic beverages should be consumed in moderation. Extreme diets, like those focusing solely on one type of food or completely eliminating meat, can lead to significant hair loss.

Diversify Your Diet

The key to preventing hair loss during dieting is to ensure a balanced intake of various foods. Extreme dietary restrictions, whether it's an all-meat or all-vegetable diet, can be harmful. A balanced diet that includes a wide range of nutrients is essential for maintaining healthy hair growth.

Hair Multivitamins: An Additional Solution

In addition to a balanced diet, hair multivitamins formulated to prevent hair loss can offer an extra layer of support. These supplements are designed to provide the essential vitamins and minerals that support hair health, filling any gaps in nutrition that a diet might leave. By ensuring your body receives a comprehensive range of nutrients, you can help minimize diet-related hair loss and support overall hair health.


While dieting can lead to hair loss due to nutritional deficiencies, this side effect can be mitigated by adopting a balanced, gradual approach to weight loss and ensuring a diverse intake of nutrients. For those looking for additional support, hair multivitamins such as Heebin's Royal Hair, Brows & Lashes can provide essential nutrients specifically targeted to enhance hair health. Remember, the goal of dieting should be not only to achieve a desired weight but also to maintain overall health, including the health of your hair.
