variation in hair strand diameters on an individual's scalp
Hair Shaft Thickness Heterogeneity refers to the variation in the diameter of hair strands on an individual's scalp or body. This means that some hairs may be thicker or thinner than others, which can be influenced by factors such as genetics, hormonal changes, or health conditions. For professionals, this heterogeneity can be an important diagnostic marker for conditions like alopecia areata or other hair disorders.
