Length, color, and curliness are macroscopic characteristics. Microscopic characteristics include the pattern of the medulla, pigmentation of the cortex, and types of scales on the cuticle (Figure 3-12). Medullary index can be measured. Typical magnification for viewing hair is between 40 times and 400 times.Click to see full answer. Simply so, what are the characteristics of hair? Terms in this set (5) texture. the size or diameter of the hair shaft. porosity. The ability of hair to absorb and hold moisture and liquid. tenacity. the degree of difficulty with which the cuticle can be penetrated. density. -the quality of number of hairs per square inch on the scalp. elasticity. Similarly, do all hairs from the same person have the same microscopic characteristics? But a microscopic look at hair can’t absolutely identify the owner. Since few people have the exact same hair characteristics, however, microscopic exams can provide compelling evidence that hair samples are associated with a certain person. If the hair root has tissue, DNA testing can provide absolute identity. In this manner, how can you identify hair under a microscope? Procedure Place a drop of water at the center of a microscope glass slide. Using a pair of forceps, place a few strands of hair onto the drop of water (or any other mountant used) Place the slide under the microscope and observe under low and high power. Compare different types of hair under the microscope. What is microscopic hair analysis?Hair analysis. Microscopic hair analysis has traditionally been used in forensics as well. Analysts examine a number of different characteristics of hairs under a microscope, usually comparing hair taken from a crime scene and hair taken from a suspect.
