Hair cortisol

Psychological stress research is often interested in measuring cortisol secretion over extended periods of time. Whilst the occasional occurrence of acute cortisol reactions may not be particularly problematic for an organism, the cumulative burden of frequent hypothalamus-pituitary-adrenal (HPA) axis activation and / or long-term changes to basal cortisol secretion is associated with a range of maladaptive effects. Common measurement strategies only reflect acutely circulating cortisol levels (blood or saliva) or cover cortisol secretion over short time periods usually not exceeding 24 h (urine). The analysis of cortisol in hair constitutes a major methodological advancement here. Being incorporated into the growing hair, hair cortisol concentrations are assumed to provide a retrospective reflection of integrated cortisol secretion over periods of several months.

Q: What do I have to pay attention to when sampling the hair for steroid analysis?

Q: What do I have to pay attention to when sampling the hair for steroid analysis?

A: The hair sampling is a very important step in the process of hair steroid analysis. This presentation will give you all relevant information concerning this subject

Q: How much hair is necessary for the hair steroid analysis?

Q: How much hair is necessary for the hair steroid analysis?

A: For hair steroid analysis one single hair strand with an overall diameter of at least 3 mm (⅛ inch) is needed. Please note, if the hair strand is too thin, a correct result cannot be guaranteed. However, hair sampling normally does not leave any visible marks and is mostly well tolerated by participants.

Q: How do I have to store the hair samples?

Q: How do I have to store the hair samples?

A: The single hair strands can be placed in separate aluminium foils and stored at room temperature over long periods of time. Please find further information concerning hair storage / packaging in this general presentation.

Q: What kind of information / what documents should be sent with the hair samples?

Q: What kind of information / what documents should be sent with the hair samples?

A: Please send us the filled out “order form” both via email (Ina.Kaden@tu-dresden.de) and place a copy in the package when sending the samples. It is important that the single packed hair samples are all labelled with consecutive numbers. Please also send us an Excel-File with all hair samples and corresponding code via email (Ina.Kaden@tu-dresden.de)
