How to perform a hair test in the privacy of my home?
One gets a list of instructions with these tests. But the most important points to note are these: You must cut hair as close to the scalp as possible. After cutting put them in the foil that come along with these kits and press the sides of the foil together, trapping the hair sample tightly inside. If hair is long, wrap the remaining hair around the foil but do not cut the ends. Now, insert the foil-wrapped sample into the Sample Acquisition Card with the root ends to the left. Seal the envelope and drop into any mailbox. No additional postage is needed for most of such kits.
