Abstract
Hair as trace evidence plays an important role during the forensic investigations. Human and animals hairs both are often recovered from the scene of crime. Human hair is a vital biomaterial, principally grows as follicle in dermal layer of skin comprises of protein, particularly keratin. Hairs are made up of keratin protein which is potentially affected by the various denaturing agents (Heat, PH, Detergent, soapy water). Hair is approximately consisting 90% of protein. This short review gives an overview about thermal denaturation of keratin protein of bleached-damaged as well as control hair and the analytical techniques that are used to monitor structural changes during thermal denaturation of keratin structure. Hair bears the high range of temperature due to that it has potential to resist the heat provided to hair. However, Continuous transformation of heat can be damaged the integrity of hair structure. It is important to determine what are the actual thermal properties of hair exists
