When hair may be used as a DNA sample, and why roots matter.
A typical scenario
A customer has hair from a relative who cannot provide a cheek swab.
Roots matter
Cut hair without roots usually contains little usable DNA; plucked hair with roots is preferred.
Assessment first
Hair is a non-standard sample and should be assessed before mailing — use Check My Sample.
Expectations
DNA recovery is not guaranteed, additional fees may apply and processing usually takes longer.
