Dear Mr. Alexander
Your query about the use of a specific hair-protective product is
very difficult for me to answer to. I am not a hair specialist. But
from our understanding of aging, some paradoxical results have come
forward, specially in relation to the hormones.
Hormones are very important for growth, development, maturation and
reproduction. But after the effective reproductive age from
evolution's point of view (which for human species is between 45 to
50 years), a chronic presence of high levels of some hormones appears
to be actually harmful. Specially, in the case of men, the presence
of high levels of testosterone and other steroids can be life
shortening. With animal studies also it has been observed that
presence of high circulating levels of these hormones causes more
damage than any good and lifespan is shortened.
The main trouble in extrapolating from animal studies to human
beings, and that too to any individual being is our inability to
really know what is the "normal" situation for an individual.
Extrreme high or extreme low levels of hormones and any effects of
such high/low levels can be picked up clinically, but the range of
"normal levels" is very large.
So, here you have my very scientific - which generally mean, very
cautious, reply to your question. I don't think this answer can be of
much use to you, but I am sure that some intelligent hormone
specialist clinician can judge better.
My general message is: if there are no bad/disease symptoms due to
the lack of hormones, then using extra hormones may not be doing any
good to the body, and may actually be harmful over long term.
All the best,
Suresh Rattan
