Hello, in an article about «DNA Collection and Archiving» I read that hair samples could be stored in a silica desiccant
dryer. 

Where can I buy a silica desiccant dryer? Thank you in advance
for answering.

Almost any place that sells lab supplies or shipping supplies. It's something you can and should find using a search engine.
