| PERMANENT HAIR DYES
Unfortunately, Foresight is unable
to accept for mineral analysis
hair samples that have been treated with permanent dyes or perming
solution.
Dyes that are intended to "stay put" contain materials
that actually penetrate the hair shaft. They can in some cases
add minerals such as lead (black dyes), manganese (brown dyes)
and copper (red dyes). In other cases they can result in some of
the minor trace minerals, which lie mainly in the outer casing
of the hair, being lost, and also zinc.
As we do the analysis on your hair for such crucial reasons, it
is essential that it is really accurate. for this reason, we have
to ask you to get us a sample that is completely free from dye.
If your hair has been dyed very recently, it may take about 6-8
weeks to grow out about 1" at the nape of the neck that is
not contaminated.
For the long term, we have very recently learned from the London
Hazards Centre that permanent dyes can enter the bloodstream from
the scalp, and can be found in the urine 40 minutes after the hair
is dyed. Recent research has linked them to bladder cancer; over
4,000 women a year are known to suffer from balder cancer, and
1,600 deaths are caused by it, with a high number of hair-dressers
being included in these.
Because the dye enters the blood, we advise people very strongly
to avoid hair dyes while the ova is ripening, and during pregnancy
and breast-feeding. It is really only sensible to keep from all
avoidable causes of cancer once you are a mother - and obviously,
if you decide not to dye, it will be doing your hair-dresser a
good turn too!
The wash-in/wash-out dyes appear at the moment to be less suspect,
but we have insufficient research on them to be able to give total
reassurance. We will try and give further updates in forthcoming
Foresight newsletters.
