Detailed answer

When consuming excessive amounts of sugar, it can lead to inflammation in the body, including the scalp. This inflammation can disrupt the natural hair growth cycle, resulting in weaker hair strands and increased hair loss. Additionally, sugar can promote the production of advanced glycation end products (AGEs), which can damage the collagen and elastin in the hair follicles, further contributing to hair thinning and loss. Moreover, a diet high in sugar can lead to nutrient deficiencies, such as decreased levels of biotin and vitamins D and E, which are essential for healthy hair growth. Lastly, excess sugar consumption can also cause imbalances in hormone levels, such as insulin resistance, which may further disrupt the hair growth process. To maintain optimal hair health, it is recommended to reduce sugar intake and maintain a balanced diet rich in essential nutrients.
