Although a single hair may appear insignificant, it can provide valuable information to forensic investigators. Hair analysis helps investigators determine whether a hair belongs to a human or an animal, identify the body area from which it originated, and sometimes establish a link between a suspect, victim, and crime scene. The scientific study of hair is known as <strong>trichology<\/strong>, and it plays an important role in forensic investigations.<\/p><div id=\"ez-toc-container\" class=\"ez-toc-v2_0_86 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title\" style=\"cursor:inherit\">Table of Contents<\/p>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" aria-label=\"Toggle Table of Content\"><span class=\"ez-toc-js-icon-con\"><span class=\"\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #0c0c0c;color:#0c0c0c\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #0c0c0c;color:#0c0c0c\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/span><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/www.legalserviceindia.com\/Legal-Articles\/forensic-hair-examination-collection-preservation-microscopic-analysis-dna-testing-and-evidentiary-value\/#Introduction\" >Introduction<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/www.legalserviceindia.com\/Legal-Articles\/forensic-hair-examination-collection-preservation-microscopic-analysis-dna-testing-and-evidentiary-value\/#Structure_of_Hair\" >Structure of Hair<\/a><ul class='ez-toc-list-level-3' ><li class='ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/www.legalserviceindia.com\/Legal-Articles\/forensic-hair-examination-collection-preservation-microscopic-analysis-dna-testing-and-evidentiary-value\/#21_Root\" >2.1.

A typical hair consists of three main parts:<\/p>\n\n\n\n<h3 id=\"h-2-1-root\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"21_Root\"><\/span>2.1. Root<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The root is the part of the hair embedded in the skin. Examination of the root can reveal whether the hair was naturally shed or forcibly removed.<\/p>\n\n\n\n<h3 id=\"h-2-2-shaft\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"22_Shaft\"><\/span>2.2. Shaft<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The shaft is the visible portion of the hair above the skin. It contains important characteristics used in forensic examination.<\/p>\n\n\n\n<h3 id=\"h-2-3-tip\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"23_Tip\"><\/span>2.3. Tip<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The tip is the end of the hair. It may be natural, cut, broken, or damaged, providing clues about grooming habits or the method by which the hair was separated.<\/p>\n\n\n\n<h2 id=\"h-internal-structure-of-hair\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Internal_Structure_of_Hair\"><\/span>Internal Structure of Hair<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The hair shaft consists of three layers:<\/p>\n\n\n\n<h3 id=\"h-3-1-medulla\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"31_Medulla\"><\/span>3.1. Medulla<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The medulla is the innermost layer of the hair. It may be continuous, fragmented, or absent. In animals, the medulla is usually wide and occupies more than half of the hair diameter. In humans, it is generally narrow and occupies less than one-third of the diameter.<\/p>\n\n\n\n<h3 id=\"h-3-2-cortex\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"32_Cortex\"><\/span>3.2. Cortex<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The cortex forms the major portion of the hair. It contains pigment granules that determine the hair&#8217;s color and provides strength and texture.<\/p>\n\n\n\n<h3 id=\"h-3-3-cuticle\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"33_Cuticle\"><\/span>3.3. Cuticle<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The cuticle is the outer protective layer composed of overlapping scales. Human hair typically has flattened scales, while animal hair often has scales that protrude outward.<\/p>\n\n\n\n<h3 id=\"h-3-4-medullary-index\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"34_Medullary_Index\"><\/span>3.4. Medullary Index<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>medullary index<\/strong> is the ratio of the diameter of the medulla to the diameter of the entire hair shaft.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Medullary Index = Diameter of Medulla \u00f7 Diameter of Hair<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This measurement helps forensic scientists distinguish between human and animal hair.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Human hair: Usually less than 0.33<\/li>\n\n\n\n<li>Animal hair: Usually greater than 0.50<\/li>\n<\/ul>\n\n\n\n<h2 id=\"h-human-and-animal-hair-comparison\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Human_and_Animal_Hair_Comparison\"><\/span>Human and Animal Hair Comparison<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Forensic scientists use several characteristics to distinguish human hair from animal hair:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Feature<\/th><th>Human Hair<\/th><th>Animal Hair<\/th><\/tr><\/thead><tbody><tr><td>Medulla<\/td><td>Narrow or absent<\/td><td>Wide and prominent<\/td><\/tr><tr><td>Medullary Index<\/td><td>Usually less than 0.33<\/td><td>Usually greater than 0.50<\/td><\/tr><tr><td>Cuticle Scales<\/td><td>Flattened<\/td><td>Project outward<\/td><\/tr><tr><td>Pigment Distribution<\/td><td>Evenly distributed<\/td><td>Often concentrated<\/td><\/tr><tr><td>Shape<\/td><td>Usually round or oval<\/td><td>Varies by species<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 id=\"h-information-obtained-from-hair-evidence\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Information_Obtained_from_Hair_Evidence\"><\/span>Information Obtained from Hair Evidence<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Hair examination can help answer several important forensic questions:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Is the sample actually hair?<\/li>\n\n\n\n<li>Is it human or animal hair?<\/li>\n\n\n\n<li>From which body part did it originate?<\/li>\n\n\n\n<li>Was it cut, pulled, or naturally shed?<\/li>\n\n\n\n<li>Has it been dyed, bleached, or chemically treated?<\/li>\n\n\n\n<li>Does it show evidence of poisoning or contamination?<\/li>\n\n\n\n<li>Can it be linked to a suspect or victim?<\/li>\n\n\n\n<li>What animal species does it belong to?<\/li>\n<\/ul>\n\n\n\n<h2 id=\"h-forensic-significance-of-hair-parts\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Forensic_Significance_of_Hair_Parts\"><\/span>Forensic Significance of Hair Parts<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3 id=\"h-6-1-root-examination\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"61_Root_Examination\"><\/span>6.1.

When properly collected, preserved, and analyzed, hair evidence continues to play a significant role in solving criminal cases and assisting the administration of justice.<\/p>\n\n\n\n<ul class=\"wp-block-yoast-seo-related-links yoast-seo-related-links\">\n<li><a href=\"https:\/\/www.legalserviceindia.com\/Legal-Articles\/marico-vs-minolta-natural-care-trade-dress-trademark-infringement-bombay-high-court-2025\/\">Marico vs Minolta Natural Care (2025): Bombay High Court Protects Trade Dress, Trademarks &amp; Consumer Trust<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/www.legalserviceindia.com\/Legal-Articles\/forensic-science-how-reliable-is-it\/\">Forensic Science: How Reliable Is It?<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/www.legalserviceindia.com\/Legal-Articles\/a-cat-helped-solve-a-murder-and-changed-crime-science\/\">A Cat Helped Solve a Murder and Changed Crime Science<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/www.legalserviceindia.com\/Legal-Articles\/legal-personality-in-law-types-of-persons-animal-rights-and-landmark-cases-in-indian-jurisprudence\/\">Legal Personality in Law: Types of Persons, Animal Rights, and Landmark Cases in Indian Jurisprudence<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/www.legalserviceindia.com\/Legal-Articles\/dna-testing-and-its-role-in-todays-legal-system\/\">DNA Testing and Its Role in Today\u2019s Legal System<\/a><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Introduction Hair is one of the most common forms of trace evidence found at crime scenes.

His tenure as Special IG and subsequently as IGP of Correctional Services, West Bengal, for over 4 years, saw him deeply engaged in improving the prison and correctional system. He visited numerous correctional homes across West Bengal, interacting with inmates, both male and female, including children residing with their incarcerated mothers. His outreach extended to correctional homes in Assam, Bihar, and Tripura. This hands-on approach provided him with invaluable insights into the workings of prisons and the complexities of the prisoner psyche. Beyond his operational roles, Md.

Imran Wahab's interests extend beyond law enforcement to include law, politics, international affairs, prison management, and business management.
