Hair Differences In Forensic Science

African American women's health, hair politics, and physical activities. Studies show that African American women tend to pay more attention to their hair instead of their health issues. Researches came up with a theoretical argument to figure out why hair matter for some women. They discover that hair presents a barrier to exercise in that the time and economic restrictions involved in maintaining a hairstyle post exercise for physical activity as prohibitive. This study provides some perception about the relationship between hair and health for African American women and suggests that extra attention is justified to address views about beauty ideals and hairstyles as a barrier to exercise (Versey, 2014, p. 2015)

At the scene of the crime a hair was found near Anna Garcia. After viewing and testing the hair, we concluded that the hair belonged to Erica. The unknown hair had the exact same thickness and color of Erica’s hair. The hair at the crime scene had a similar cuticle to Erica’s. Both Erica’s hair and the one at the crime scene had the same cortex as well. We believe that Erica’s hair was brought to the crime scene on a piece of clothing by Alex Garcia(Anna’s ex-husband). When Alex came to murder Anna a hair of Erica’s must have fallen off when Alex was doing his deed.

In regards to hair communities there are different patterns of hair textures. Everyone has different DNA, skin color, and of course hair. Hair textures all over the world have different types. This refers to your specific pattern of hair. This goes from one to four and has specialized divisions labeled A, B, C. The first is 1A, which is described as bone straight. 1B is not completely straight and holds a curl easier. 1C has slight waves and is not fully straight. The second category of hair is wavy or “S” shaped. 2A is loose, and beachy; 2B is tighter and more defined. Lastly 2C is susceptible to more frizz with small spiral like curls. The third is curly. This goes to 3A, which has the curl diameter of sidewalk chalk. 3B refers to a curl

DNA from animals and plants can also be utilized in criminal forensics. One of the most common applications of this is the analysis of pet hair from a crime scene, which often links its owner to the crime. DNA fingerprints have also been applied to cannabis plants, and a database is being created to trace samples to their sources. This has been extremely successful so far, as this technology can distinguish between closely related, carefully bred plants (Westphal, 2003). Heather Miller Coyle of the Connecticut

Trichology is the study of hair. Interestingly, this study dates back to mid-1800s. However, hair analysis in forensic science began in 1930. During which time, a forensic scientist by the name of Edmond Locard introduced the Locard Exchange Principal. This principal hinges on the fact that any time there is contact between two surfaces an exchange of material will take place. (Oien, 2009) In this paper, I will prove how Forensic Hair Analysis and Forensic Hair comparison and studies if properly performed and correctly interpreted hair analysis meets all the scientific method standards.

Trace evidence- very small amounts of certain physical evidence that is found at a crime scene. Example of trace evidence include blood, hair particles, glass, gunpowder and fingernails. The different types of trace evidence are biological and physical. Biological evidence are samples collected at a crime scene that contain biological material. Examples of biological evidence include hair, tissue, bones, teeth, blood, semen or other bodily fluids or evidence containing biological material. Physical evidence is any item that comes from a nonliving origin. Examples of physical evidence includes fingerprints, footprints, tire marks, fibers, paints and building materials. The importance of trace evidence in forensic science specifically hairs and fibers are that they contain DNA, which can be traced back to the origin. An important figure in the history of forensic science was Edmond Locard who came up with the transfer of evidence. He called this Locard’s exchange principle which means that when two objects come into contact with one another a cross-transfer of materials occurs. An example of Locard’s exchange principle can be when jean fibers come into contact with a computer chip and a transfer of materials occurs. In this example Locard’s exchange principle relates to

“Live your beliefs and you can turn the world around” said Henry David Thoreau. If you do not stand strong for your beliefs, you’ll fall for anything. After I get accepted into the Lewis and Clark Business program and getting my masters in business, I plan on going to The Skin Institute to achieve my Esthetician license. In the Cosmetology world, I have to test the waters, and stand out. There are a lot of people that believe that if a person has unnatural hair color, “odd” haircuts, or a lot tattoos or piercings, that they are automatically a bad person.

The only way to know if Wen By Chaz delivers beautiful hair without trying it yourself is to read a review with pictures from a self-described hair care fanatic who works in a hair salon. Emily McLure's review on Bustle is very informative as she includes pictures on her hair from day one of the test to day seven.

On October 18, 1977, James Anagnos was found dead in his bar. The suspect was Frank Wright, who detectives learned was in an argument with Anagnos a few hours before closing time. Anagnos had a chunk of hair in his hand, and it was sent to a secret laboratory in Texas to get tested. Later the DNA confirmed that the hair belonged to Wright.

Unwanted facial and body hair can be a source of distress for both men and women. Since the early 1990 laser has become a widely accepted and a safe method for treatment of excessive hair growth provided it is done by trained hands. Excerpts from the talk with Dr.Anshul Jain , M.D. (Skin) regarding myths about Laser Hair Removal.

The transfer of animal hairs at a crime scene have played a vital role in solving countless crimes. Animal hairs can lay dormant at a crime scene or can be transferred from victim to or from the scene. Animals have their own unique DNA. Any animal hairs found in a particular location can be tested against a specific animal to rule out the likelihood of that specific follicle coming from that specific

Each year about 33,000 crimes are solved by DNA database, therefore, showing that DNA has an important element when determining and finding potential suspects who may have committed the crime. DNA, or deoxyribonucleic acid, is a substance that makes up an individual's genetic identity. DNA is found in all organisms, but more the abundance of DNA is found in cells which include a nucleus or “nucleated cells”(“preservation and collection of biological evidence”). Within a crime scene detectives and officers can use common materials such as tissues, pillows, a bottle, and more. When a detective finds cases in which DNA is present, they can take the samples back to lab to extract and quantify the DNA to see if they can do further analysis on

My long term goal in life is becoming independent. It enables me to take care of myself while looking out for another person. There’s no shortcut in pursuing an aspect in life. This first step considers how what I ought to do for a living. What I want to do is hairdressing. The hairdressing career interests me because I like to braiding hair, twisting, cutting it, and sometimes adding color to it for style.

Bad news for modern women: Many of today's common hair care practices are not great for hair follicles. "The types of alopecia we're seeing are different than what we were seeing 20 years ago because of the different types of processing that people are doing now," says Roopal V. Kundu, MD, Associate Professor of Dermatology at Northwestern University's Feinberg School of Medicine, "Whereas in the '70s and the early '80s the hairstyles were more natural, these days there's a lot more crunched out styles in terms of perms and putting heat in the hair and keeping it straight, and a lot of tension."
