Eh, you dye your hair?
Yah lah, bo bian, too many white hair
You know the red will just fade and soon you will see all the white again, right?
Serious?
Yah
Hmm... interesting
We all have friends who has gray hair, 我们都有灰发的朋友
whether he is 25 or 52
But do you know that Asians like us would have white hair later, compared to Caucasians?
And also, do you know that the story of pulling one white hair out would cause three white hair to grow out
is... merely a myth
Here are eight facts about graying hair you should know
So you won't end up like him
First thing first: What is white hair?
Usually, we call it graying hair, as the entire hair looks gray instead of pure black
Basically, our hair colour is caused by Melanin, something that creates hair
When we have less Melanin
the hair starts to lose colour
and so, it will turn gray first, than white
For people who has just white hair
It's due to the complete lack of Melanin for our hair
Melanin is a pigment
and it's not only responsible for our hair,but for our skin colour too
Obviously, this is affected by our genes
For people who have darker skin
they usually have more melanin in their skin
Now, if you have got freckles
it is also due to the increased Melanin production in your skin
Okay, enough of the science lesson: let us move on to something everyone is dying to know
What causes the melanin in our hair to just AWOL?
You know, just like any part of our body
We get weaker as we grow older
Same thing for Melanin
In order for it to work, it gets a specialized cell known as melon
How to pronounce arh?
Yes, melanocyte
As we grow older
It loses its function about 10% to 20% every ten years after 30 years old
So grey hair is actually normal 所以灰发是正常的
But hey, there is another discovery
Hydrogen Peroxide, the New Discovery about Hair Loss
It is said that as we grow older
Our hair builds up hydrogen peroxide
Basically, our body builds this up on a regular basis as a byproduct for survival
They are usually neutralized by an enzyme by our body
As we grow older, the enzyme gets lower
and tada: it's not broken down anymore
and our hair is bleached by our own body
Whichever discovery you believe in, here's the thing
Premature white hair, which isn't caused by aging
can somehow be prevented. Watch on.
We all have friends who're like 20 and have white hair
Why, you might ask
Genes play a large role
but there are several external factors that contribute to the lack of Melanin
or the enzyme that breaks down hydrogen peroxide
Stress, smoking, unbalanced diet are a few examples
Reason being, if your body is working as usual
the Melanin levels would be normal
But if you, say, smoke a lot
it'll change the level and your hair would age faster
Actually, it's not just your hair, but you get the idea
The solution is to always keep yourself healthy
After watching all these, it should be obvious that
If you pluck out one white hair, just one more would replace it
I'm not sure where the theory of
"pluck one white hair leads to three" comes about
but here's something based on fact
If you pluck out one white hair, it might not grow again
as the hair follicle would be damaged
So remember: don't pluck any hair
Here's something interesting
Men have more gray hair than women
And Asians are less likely to have gray hair than ang mos
even so, they'll have it later
Generally, Asians start to have white hair in their late thirties
while ang mos in their mid-thirties
So if you're thinking of becoming a George Clooney in your 30s
forget about it
So, you're starting to see some gray hair on your head
and wonder if any other parts of your body hair is going to turn white as well
The short answer is
Yes
If you've watched through the boring science lesson in the beginning of this video
you'll know that it affects not just your hair
but your entire body as well
So if you're dyeing your hair black to cover your grey hair
you might want to consider dyeing other parts of your body too
We've spoken about how smoking affects your hair colour
but here's one shocking fact for you
A 2013 study reveals that smokers are 2.5 times more prone to have white hair earlier than non-smokers
So, if you've friends who have white hair
chances are they might be a smoker
