Hair develops from follicles found in the dermis or skin. It is one of the distinguishing features of warm-blooded creatures. The human body is covered in follicles which produce both thick terminal hair and fine vellus hair, except for areas of glabrous skin. Hair is primarily made of protein keratin and serves as a vital biomaterial, though attitudes towards hair vary across societies and time periods, and is sometimes used to indicate age, gender, or religion.

Abstract
Mammalian hair is structured into various components. This paper aims to establish the structural characteristics of mammalian hair. The most basic structure is the medulla, the cortex, and the cuticle. The paper also explores the other substructures of hair among the three main structures. The research paper also includes pictures describing the various structures of hair that have been highlighted herein. The differences in structure between different types of hair has also been captured and real examples of species with those structural variations in morphology provided. The findings of this paper were arrived from the poster project based on the color and thickness of head hair of a Turkish mail and through performing academic research in credible sources of information such as journals. Informative internet websites were also included in the research. Research results from our own group experiment related to biological imaging and other experiments related to mammalian hair observations have also been used in establishing the facts of the paper. Different types of mammalian hair from different species was observed under a microscope and the observations recorded. The paper establishes the structural microscopic differences in the structure human hair from different species of animals such as difference in the medulla and the cuticle. These differences are useful in telling species apart by using microscopic characteristics of hair.

INTRODUCTION
Hair is the slender outgrowth from the skin of most mammals through the skin follicle. A growing hair originates from the papilla and is made up of dead, cornified cells. Basically, hair is made up of a protein called keratin and a black pigment known as melanin which gives color to the skin. It is not uncommon to find trace elements of metals in hair and melanin. Such elements of metals are usually deposited in the hair at the time of growth or they can be absorbed into the hair from external pollutants. Once hair is grown, it goes into telophase or resting stage after which the hair is shed. Mammalian hair from different parts of the body has different structures. This makes it necessary to compare mammalian hair structure from the same place of the body. For example, in an experiment to examine the structure of a mammalian hair, the following procedure can be used;
MATERIALS AND METHODS
Materials
grains of mammalian hair.
Methods
· Place the sample of human hair under a microscope.
· Using a Zeiss Discovery V12 microscope
· Starting with an objective lens of 63x*13.8x observe the specimen then move to 63x*79x
· Record the obse.
This ppt gives information about the hair structure, function of hair, hair cycle(all phase are explain in this ppt) how to maintain healthy hair during all the phase of the hair cycle.

Trichotillomania (trik-o-til-o-MAY-nee-uh), also called hair-pulling disorder, is a mental disorder that involves recurrent, irresistible urges to pull out hair from your scalp, eyebrows or other areas of your body, despite trying to stop.
Hair pulling from the scalp often leaves patchy bald spots, which causes significant distress and can interfere with social or work functioning. People with trichotillomania may go to great lengths to disguise the loss of hair.
For some people, trichotillomania may be mild and generally manageable. For others, the compulsive urge to pull hair is overwhelming. Some treatment options have helped many people reduce their hair pulling or stop entirely.Symptoms
Signs and symptoms of trichotillomania often include:
Repeatedly pulling your hair out, typically from your scalp, eyebrows or eyelashes, but sometimes from other body areas, and sites may vary over time
An increasing sense of tension before pulling, or when you try to resist pulling
A sense of pleasure or relief after the hair is pulled
Noticeable hair loss, such as shortened hair or thinned or bald areas on the scalp or other areas of your body, including sparse or missing eyelashes or eyebrows
Preference for specific types of hair, rituals that accompany hair pulling or patterns of hair pulling
Biting, chewing or eating pulled-out hair
Playing with pulled-out hair or rubbing it across your lips or face
Repeatedly trying to stop pulling out your hair or trying to do it less often without success
Significant distress or problems at work, school or in social situations related to pulling out your hair
Many people who have trichotillomania also pick their skin, bite their nails or chew their lips. Sometimes pulling hairs from pets or dolls or from materials, such as clothes or blankets, may be a sign. Most people with trichotillomania pull hair in private and generally try to hide the disorder from others.
For people with trichotillomania, hair pulling can be:
Focused. Some people pull their hair intentionally to relieve tension or distress — for example, pulling hair out to get relief from the overwhelming urge to pull hair. Some people may develop elaborate rituals for pulling hair, such as finding just the right hair or biting pulled hairs.
Automatic. Some people pull their hair without even realizing they're doing it, such as when they're bored, reading or watching TV.
The same person may do both focused and automatic hair pulling, depending on the situation and mood. Certain positions or rituals may trigger hair pulling, such as resting your head on your hand or brushing your hair.
Trichotillomania can be related to emotions:
Negative emotions. For many people with trichotillomania, hair pulling is a way of dealing with negative or uncomfortable feelings, such as stress, anxiety, tension, boredom, loneliness, fatigue or frustration.
Positive feelings.

As Europe's leading economic powerhouse and the fourth-largest hashtag#economy globally, Germany stands at the forefront of innovation and industrial might. Renowned for its precision engineering and high-tech sectors, Germany's economic structure is heavily supported by a robust service industry, accounting for approximately 68% of its GDP. This economic clout and strategic geopolitical stance position Germany as a focal point in the global cyber threat landscape.
In the face of escalating global tensions, particularly those emanating from geopolitical disputes with nations like hashtag#Russia and hashtag#China, hashtag#Germany has witnessed a significant uptick in targeted cyber operations. Our analysis indicates a marked increase in hashtag#cyberattack sophistication aimed at critical infrastructure and key industrial sectors. These attacks range from ransomware campaigns to hashtag#AdvancedPersistentThreats (hashtag#APTs), threatening national security and business integrity.
🔑 Key findings include:
🔍 Increased frequency and complexity of cyber threats.
🔍 Escalation of state-sponsored and criminally motivated cyber operations.
🔍 Active dark web exchanges of malicious tools and tactics.
Our comprehensive report delves into these challenges, using a blend of open-source and proprietary data collection techniques. By monitoring activity on critical networks and analyzing attack patterns, our team provides a detailed overview of the threats facing German entities.
This report aims to equip stakeholders across public and private sectors with the knowledge to enhance their defensive strategies, reduce exposure to cyber risks, and reinforce Germany's resilience against cyber threats.
