The advantages of hair analysis include the non-invasiveness, low cost, and the ability to measure a large number of, potentially interacting, toxic and biologically essential elements. Hence, head hair analysis is increasingly being used as a preliminary test to see whether individuals have absorbed poisons linked to behavioral or health problems.
Forensic DNA analysis can be a useful tool in aiding forensic identification because DNA is found in almost all cells of our bodies except mature red blood cells. Deoxyribonucleic acid is located in two different places of the cell, the nucleus; which is inherited from both parents, and the mitochondria; inherited maternally.
Short tandem repeat (STR) analysis is the primary type of forensic DNA analysis performed in modern DNA laboratories. STR analysis builds upon RFLP and AmpFLP used in the past by shrinking the size of the repeat units, to 2 to 6 base pairs, and by combining multiple different loci into one PCR reaction.
The National Institute of Standards and Technology has reviewed the scientific foundations of bite-mark analysis used in forensic science. Bite mark analysis is a forensic science technique that analyzes the marks on the victim's skin compared to the suspects teeth. [107]

A recent development in forensic science is the isotopic analysis of hair strands. Hair has a recognisable growth rate of 9-11mm [26] per month or 15 cm per year. [27] Human hair growth is primarily a function of diet, especially drinking water intake.
Alex J. Krotulski, who runs the toxicology and chemistry lab at the Center for Forensic Science Research & Education in Horsham, Pennsylvania, analyzes samples for police and other clients.
Bloodstain pattern analysis (BPA) is a forensic discipline focused on analyzing bloodstains left at known, or suspected crime scenes through visual pattern recognition and physics-based assessments. This is done with the purpose of drawing inferences about the nature, timing and other details of the crime. [ 1 ]
