Dr Knowles, Dr Knowles, you've got to help me. | 0:06:02 | 0:06:04 | |
I've been invited to the annual beekeepers' ball tonight. | 0:06:04 | 0:06:07 | |
Ooh! That's exciting, Colin. | 0:06:07 | 0:06:09 | |
I know it is, but I can't go looking like this. | 0:06:09 | 0:06:13 | |
Hmm... Well, your look is a little... vintage. | 0:06:13 | 0:06:16 | |
-BANG -Hey, lads, look what I got. | 0:06:16 | 0:06:19 | |
A total makeover kit, 100% satisfaction guaranteed. | 0:06:19 | 0:06:23 | |
Who wants to be on my guinea pig? Huh? | 0:06:23 | 0:06:25 | |
Oh, I think I know where this is headed. | 0:06:25 | 0:06:27 | |
This is Brain Freeze. | 0:06:27 | 0:06:31 | |
With Dr Knowles... | 0:06:31 | 0:06:33 | |
Professor McCourt... | 0:06:33 | 0:06:36 | |
And Colin, the floor manager. | 0:06:36 | 0:06:40 | |
Stand-by! | 0:06:40 | 0:06:44 | |
Hello again and welcome to Brain Freeze. | 0:06:50 | 0:06:53 | |
It's time for... | 0:06:53 | 0:06:54 | |
Today's question is... | 0:06:57 | 0:06:58 | |
Well, first things first, all mammals have hair, | 0:07:00 | 0:07:03 | |
and the primary function of hair is to keep us warm. | 0:07:03 | 0:07:05 | |
Even before we are born, we have a layer of fine, downy hair | 0:07:05 | 0:07:09 | |
which prevents body heat from escaping. | 0:07:09 | 0:07:11 | |
Yeah, that'd explain all the hairy babies in our family. | 0:07:11 | 0:07:14 | |
Now, there are two other types of hair. | 0:07:17 | 0:07:19 | |
The very fine colourless hair found on most of our bodies | 0:07:19 | 0:07:22 | |
and the thicker, longer, darker hair that grows on our heads. | 0:07:22 | 0:07:25 | |
So we're pretty much covered all over in some kind of hair? | 0:07:25 | 0:07:29 | |
That's right. In fact, there are only a few places where hair doesn't grow. | 0:07:29 | 0:07:33 | |
These include your lips, the palms of your hands | 0:07:33 | 0:07:36 | |
and the soles of your feet. | 0:07:36 | 0:07:37 | |
That's proof enough for me. Basically we're monkeys. | 0:07:37 | 0:07:40 | |
-Ooh-ooh! -Well, speak for yourself, Professor! -Ooh-ooh-ah! | 0:07:40 | 0:07:44 | |
We'll be right back after this break. | 0:07:44 | 0:07:46 | |
And we are clear! | 0:07:47 | 0:07:49 | |
OK, Colin, take a deep breath and prepare to be transformed. | 0:07:49 | 0:07:54 | |
Oh, crumpets! I don't like this. | 0:07:54 | 0:07:57 | |
Meet Colin, he's a floor manager from the Midlands | 0:07:57 | 0:08:00 | |
with the fashion sense of a sausage. | 0:08:00 | 0:08:02 | |
We need to freshen up his dated look and make him feel like 1 million. | 0:08:02 | 0:08:07 | |
Work it, Colin. Own it! | 0:08:07 | 0:08:09 | |
Yeah, baby. That's the look. | 0:08:09 | 0:08:12 | |
Oh, stop it! This is all wrong. | 0:08:12 | 0:08:14 | |
-BELL -Positions! | 0:08:14 | 0:08:16 | |
Welcome back. Lynn got in touch to ask | 0:08:18 | 0:08:20 | |
"So what is hair exactly and how does it work?" | 0:08:20 | 0:08:23 | |
Our skin contains over 5 million tiny openings called hair follicles. | 0:08:23 | 0:08:28 | |
Inside these follicles, hair cells work together | 0:08:28 | 0:08:31 | |
to produce the hard protein, keratin, | 0:08:31 | 0:08:33 | |
which forms the hair shaft that grows out from the root. | 0:08:33 | 0:08:36 | |
Oh, don't talk to me about roots! | 0:08:36 | 0:08:38 | |
The root is the living part of the hair | 0:08:38 | 0:08:40 | |
and it's connected to blood vessels, | 0:08:40 | 0:08:42 | |
nerve endings and other glands | 0:08:42 | 0:08:44 | |
that help it function. | 0:08:44 | 0:08:45 | |
Well, we all need a little help from time to time. | 0:08:45 | 0:08:48 | |
But by the time the hair has reached the skin surface, | 0:08:48 | 0:08:50 | |
it's made up entirely of dead cells. | 0:08:50 | 0:08:52 | |
Which leads us conveniently to... | 0:08:52 | 0:08:54 | |
So, Dr Knowles, why doesn't a haircut hurt? | 0:08:57 | 0:09:01 | |
What the...? Well, the answer is quite simple. | 0:09:01 | 0:09:04 | |
There are no nerve endings in the dead part of our hair, | 0:09:04 | 0:09:07 | |
so we don't feel anything when it's cut. | 0:09:07 | 0:09:09 | |
But it does hurt if we pull hair | 0:09:09 | 0:09:11 | |
because we're pulling out all the little nerves inside the roots. | 0:09:11 | 0:09:14 | |
-See you next time on Brain Freeze! -Toodle-oo. | 0:09:14 | 0:09:17 | |
-Hey! Where's Colin? -I'm in here, Dr Knowles! | 0:09:20 | 0:09:23 | |
I'm just putting the finishing touches to my new look. | 0:09:23 | 0:09:27 | |
-Ooh, let's see, let's see! -Very well. Prepare to be amazed! | 0:09:27 | 0:09:32 | |
But... Em... What happened to... ? | 0:09:33 | 0:09:36 | |
I decided, Dr Knowles, that I'm happy just the way I am. | 0:09:36 | 0:09:40 | |
You know what, Colin, you're right. | 0:09:40 | 0:09:42 | |
Well, perhaps just a hint of styling cream. | 0:09:42 | 0:09:46 | |
Beekeepers' ball, here I come! | 0:09:46 | 0:09:49 | |
Oh, honestly, Dr Knowles. | 0:09:49 | 0:09:51 | |
Some people just don't know style when they see it. | 0:09:51 | 0:09:54 | |
Argh! | 0:09:54 | 0:09:56 | |
