Shipping & Packaging Instructions for Hair Samples


  • Place hair samples in a foil packet (see examples).
    • For longer hair, loop the sample without bending the hair sharply (see example 1 “do” & 9 “don’t”).
    • Clearly delineate the scalp end of the hair by banding the hair near the scalp end, noting the scalp end marker on the foil, or preferably both (see example 1 & 2).
  • Fold the foil packet such that it makes an envelope over the hair (see example 3).
  • Label the foil envelope with all relevant sample information (see example 4).
  • Place the hair sample in a manila envelope for shipping. If sending less than 15 samples please use a padded envelope.  
  • Label the envelope with all relevant sample information (see example 5).
  • Keep the sample at room temperature.
  • Label samples in a clear and legible manner.
    • Please include participant biological sex when possible.
  • Please use a tracked shipping method.
