this episode of life noggin is brought
to you by aj+ hey there i'm blanco and i
might be an ageless animation but you on
the other hand are getting older every
day and with old age comes a lot of
interesting changes it's Thursday so
that means we're answering one of your
questions and this week we're gonna find
out why does hair turn gray with old age
let's do this let's figure out how hair
gets its color in the first place
hair like the skin gets its color from a
pigment called melanin did you know that
melanin formation happens before we're
born did you know that all hair is white
before it grows while you do now dark
pigments are called you melanin and like
pigments are called pheomelanin which
blend together to create a broad
spectrum of beautiful hair colors these
pigments are composed of cells called
melanocytes that are positioned on the
skin surface which the hair follicles
grow through melanocytes inject melanin
into cells that contain keratin which
the protein or hair is made up of there
are many factors that can change the
pigment of your hair both internal and
external things such as genetics
hormones age the climate that you live
in toxins and even chemical exposure can
all affect hair pigmentation I would
check with your parents or grandparents
and find out when they went gray that's
when you probably will too as you grow
older your hair turns gray as the result
of failed maintenance of melanocytes
cells they may die or just function
improperly the less melanin you have the
gray or your hair becomes each hair
follicle grows separately and contains
its own amount of melanin this is why
certain hairs turn gray at different
times there is still no solid proof as
to why this happens more recent studies
have shown the hair follicles produce
small amounts of hydrogen peroxide which
over time can lead to a gradual loss of
hair color I personally would take gray
hair over a hairless blockhead any day
thank you so much for watching as usual
I'll be answering a new question every
Thursday so ask anything you want to
know in the comments or on Facebook and
Twitter if you liked this video you
should definitely click the one that
just popped up on the screen or check
the description for the link but the
pudding is in the eating the meaning
behind this expression is that to
experience something to the fullest you
need to try it out yourself like pudding
try it you'll like it
unless you're allergic somehow I'm like
oh this has been life noggin don't
forget to keep on thinking
