How do I take a hair sample?

Using your forefinger and thumb gather 3 or 4 strands and slightly twist the hair together. This will make cutting the hair sample much easier and keep all the hair strand in the same direction.

Try to cut the hair sample as close to the scalp as possible, using one cut. We do not need the follicle (bulb) for the testing.

You do not actually have to cut your hair. You can brush your hair and collect hair strands from your hairbrush.
