For hair samples, what is the best short-term storage condition?

For hair samples, the best short-term storage condition is temperature-controlled environments. Storing hair in a temperature-controlled setting helps maintain sample integrity by minimizing the effects of temperature fluctuations that can lead to degradation or contamination. It ensures that the hair retains its physical and chemical properties, which is crucial for accurate forensic analysis.

Room temperature can lead to issues with potential contamination and degradation over time, so it isn't ideal for maintaining the integrity of the hair samples. Refrigerated storage would also be inadequate for any long-term preservation, as this does not control for moisture or other environmental factors that might affect the sample. Similarly, while freezing might preserve samples over longer periods, the immediate needs of short-term storage are better met with temperature control that allows for consistent and stable conditions.
