On average, Asians, particularly East Asians, tend to have the thickest hair, meaning each individual strand has the largest diameter. While other ethnicities may have higher hair density (more strands per square inch), the individual hair strand thickness is generally greater in East Asians.
Understanding Hair Thickness
Hair thickness is determined by the diameter of each individual hair strand. This differs from hair density, which refers to the number of hair strands per square inch of scalp. It's important to distinguish between these two aspects when discussing hair thickness.
- Diameter: This measures the width of a single hair strand. Studies indicate that Asian hair often has a diameter of 80-120 µm.
- Density: This measures the number of hair strands per square inch of the scalp. Caucasian individuals often have higher hair density than those of Asian descent.
Multiple sources confirm that Asian hair tends to have the largest diameter of individual strands. However, individual variations exist within and across ethnic groups, making generalizations challenging. Anecdotal evidence from online forums and social media further supports the observation of incredibly thick hair in individuals of various ethnicities.
These sources further highlight the complexity of defining “thickest hair.” The question needs to specify whether it refers to:
- Individual strand thickness: In this case, East Asians generally have the thickest strands.
- Overall hair volume: This depends on both the thickness of individual strands and hair density, making it difficult to definitively say who has the thickest hair overall.
Therefore, a precise answer requires clarity on the definition of "thickest hair."
