Impacts of Obesity on Hair Health

03 Aug, 2023

Obesity has become a prevalent health concern worldwide, affecting millions of individuals. While the detrimental effects of obesity on physical health are well-known, its impact on hair health is often overlooked. Obesity can have various adverse effects on the body, and one area that can be significantly affected is the health and appearance of the hair. In this blog post, we will explore the causes and effects of obesity on hair health, shedding light on this lesser-known aspect of the obesity epidemic.

Causes of Hair Problems in Obesity:

  • Nutritional Deficiencies: Obesity is often associated with a diet high in processed foods, sugars, and unhealthy fats. Such a diet may lack essential nutrients like vitamins, minerals, and proteins, which are vital for maintaining healthy hair. Inadequate nutrition can lead to hair thinning, dullness, and increased susceptibility to damage and breakage.
  • Hormonal Imbalances: Obesity is frequently linked to hormonal imbalances, particularly an excess of oestrogen and insulin resistance. These hormonal imbalances can disrupt the natural hair growth cycle, leading to hair loss. Elevated levels of estrogen can trigger a condition known as androgenic alopecia, commonly referred to as female or male pattern baldness.
  • Inflammation: Obesity is associated with chronic low-grade inflammation throughout the body. This inflammation can affect hair follicles, impeding their ability to produce healthy hair. Inflammatory substances released in the body can disrupt the growth phase of the hair cycle, leading to hair loss or thinning.

Effects of Obesity on Hair Health:

  • Hair Loss: Obesity can contribute to various forms of hair loss, including androgenic alopecia and telogen effluvium. Androgenic alopecia, as mentioned earlier, is a genetic condition that causes pattern baldness. Telogen effluvium is a temporary hair loss condition triggered by hormonal changes, nutritional deficiencies, or physical or emotional stress. Obesity can increase the risk of these hair loss conditions, leading to noticeable thinning or bald patches.
  • Reduced Hair Quality: Poor dietary choices associated with obesity can result in weak, brittle hair that lacks lustre and vitality. Nutrient deficiencies can affect the structure and strength of hair strands, making them prone to damage and breakage. Additionally, the chronic inflammation caused by obesity can disrupt the normal hair growth cycle, resulting in slower hair growth and a compromised overall hair quality.
  • Scalp Issues: Obesity can contribute to various scalp conditions, including dandruff, seborrheic dermatitis, and fungal infections. These conditions can cause scalp itching, flaking, redness, and inflammation, leading to discomfort and potentially exacerbating hair loss.
  • Psychological Impact: Hair loss and poor hair health can significantly impact an individual’s self-esteem and body image. Obesity already carries a stigma in society, and when combined with hair-related issues, it can lead to increased stress, anxiety, and lowered self-confidence. This can create a vicious cycle, as increased stress can further exacerbate hair problems.

Addressing Hair Health in Obesity:

  • Balanced Diet: Adopting a balanced diet rich in essential nutrients is crucial for maintaining healthy hair. Include a variety of fruits, vegetables, lean proteins, whole grains, and healthy fats in your meals to provide the necessary vitamins and minerals for optimal hair growth.
  • Weight Management: Managing weight through a combination of a healthy diet and regular physical activity can help regulate hormone levels and reduce inflammation. This, in turn, can positively impact hair health.
  • Consultation with Professionals: If experiencing hair-related issues, consult with a healthcare professional or a dermatologist specialising in hair health. They can evaluate your condition, identify any underlying causes, and recommend appropriate treatments or interventions.
  • Stress Management: Implement stress-reducing techniques such as meditation, yoga, or engaging in hobbies to manage stress levels. High-stress levels can exacerbate hair problems, so it is essential to address this aspect as well.


While the impact of obesity on overall health is widely recognized, its effects on hair health should not be overlooked. Nutritional deficiencies, hormonal imbalances, inflammation, and other factors associated with obesity can lead to hair loss, reduced hair quality, and scalp issues. By adopting a balanced diet, managing weight, consulting a trichologist, and addressing stress levels, individuals can mitigate the negative effects of obesity on hair health. Remember, a holistic approach to overall health is essential for maintaining vibrant, healthy hair.
