Your Questions Answered...
What
if the hair is too short to cut?
Stainless steel thinning shears may be used by placing them next to the
scalp.
What
if there is no new growth because of recent chemical coloring or perming?
It is best to wait until new growth is available--hair grows approximately
1/2 inch per month. If an analysis is needed before then, save as much
new growth as possible from the roots and take samples from additional
places.
May
I use hair from other parts of my body?
Yes. Ideally, you should use hair from your scalp, although hair from
your pubic area is acceptable as well. It is important that you use hair
from one area only. Mixing hair from different areas of your body will
render the analysis inaccurate. You must indicate on the requisition form
from which area you have collected the sample .
How
much scalp hair is needed?
A sufficient amount of hair is needed to properly analyze your sample.
Make sure that the amount of hair in your sample tips the hair scale,
as shown in Step 5. Insufficient hair samples cannot be processed.
