Hi. in an article about "DNA Collection and Archiving" I read that hair samples could be stored in a silica desiccant dryer. I live in Norway, so I found a possible source

Which one of the silica desiccants in the link below would be most suitable for

long term storage of hair for at least 5 years? I plan to store the hair in room temperature.  Thank you for answering.
