What is hair analysis? In 1982, microscopic hair analysis of strands found on the body of a victim was used and Dennis Fritz and Ron Williamson were framed for the murder. Seventeen years later, DNA analysis of the same hair fragments was used to prove that these men were innocent. As this case shows, hair analysis has come a long way the past thirty years. Hair analysis, basically, is the scientific examination of a hair sample. It can be hair from a crime scene examined to find out who committed the act, or it can be hair taken from the back of your head and sent to a laboratory where it is checked for signs of health problems.
Fortunately, conjoint analysis can facilitate the process. Conjoint analysis is a tool that allows a subset of the possible combinations of product features to be used to determine the relative importance of each feature in the purchasing decision. Conjoint analysis is based on the fact that the relative values of attributes considered jointly can better be measured than when considered in isolation. In a conjoint analysis, the respondent may be asked to arrange a list of combinations of product attributes in decreasing order of preference.
