Tag: Thin eyebrows

According to the World Health Organization, iron deficiency is the most common nutritional deficiency worldwide, and it is a known contributor to hair loss. So, can low iron cause thin eyebrows? The answer is yes, as insufficient iron levels can disrupt the hair growth cycle, affecting not only the hair on your head but also the delicate follicles of your eyebrows.

While over-plucking is a well-known culprit for sparse eyebrows, nutrient deficiencies are a significant, often overlooked cause. Understanding what vitamin deficiency causes thin eyebrows is the first step toward addressing the issue. A balanced diet is critical for hair growth, and a lack of certain vitamins can disrupt the hair cycle and damage follicles, affecting not just the hair on your head but also your brows.
