0:05:50 > 0:05:57.
0:06:02 > 0:06:04Dr Knowles, Dr Knowles, you've got to help me.
0:06:04 > 0:06:07I've been invited to the annual beekeepers' ball tonight.
0:06:07 > 0:06:09Ooh! That's exciting, Colin.
0:06:09 > 0:06:13I know it is, but I can't go looking like this.
0:06:13 > 0:06:16Hmm... Well, your look is a little... vintage.
0:06:16 > 0:06:19- BANG - Hey, lads, look what I got.
0:06:19 > 0:06:23A total makeover kit, 100% satisfaction guaranteed.
0:06:23 > 0:06:25Who wants to be on my guinea pig? Huh?
0:06:25 > 0:06:27Oh, I think I know where this is headed.
0:06:27 > 0:06:31This is Brain Freeze.
0:06:31 > 0:06:33With Dr Knowles...
0:06:33 > 0:06:36Professor McCourt...
0:06:36 > 0:06:40And Colin, the floor manager.
0:06:40 > 0:06:44Stand-by!
0:06:50 > 0:06:53Hello again and welcome to Brain Freeze.
0:06:53 > 0:06:54It's time for...
0:06:57 > 0:06:58Today's question is...
0:07:00 > 0:07:03Well, first things first, all mammals have hair,
0:07:03 > 0:07:05and the primary function of hair is to keep us warm.
0:07:05 > 0:07:09Even before we are born, we have a layer of fine, downy hair
0:07:09 > 0:07:11which prevents body heat from escaping.
0:07:11 > 0:07:14Yeah, that'd explain all the hairy babies in our family.
0:07:17 > 0:07:19Now, there are two other types of hair.
0:07:19 > 0:07:22The very fine colourless hair found on most of our bodies
0:07:22 > 0:07:25and the thicker, longer, darker hair that grows on our heads.
0:07:25 > 0:07:29So we're pretty much covered all over in some kind of hair?
0:07:29 > 0:07:33That's right. In fact, there are only a few places where hair doesn't grow.
0:07:33 > 0:07:36These include your lips, the palms of your hands
0:07:36 > 0:07:37and the soles of your feet.
0:07:37 > 0:07:40That's proof enough for me. Basically we're monkeys.
0:07:40 > 0:07:44- Ooh-ooh!- Well, speak for yourself, Professor!- Ooh-ooh-ah!
0:07:44 > 0:07:46We'll be right back after this break.
0:07:47 > 0:07:49And we are clear!
0:07:49 > 0:07:54OK, Colin, take a deep breath and prepare to be transformed.
0:07:54 > 0:07:57Oh, crumpets! I don't like this.
0:07:57 > 0:08:00Meet Colin, he's a floor manager from the Midlands
0:08:00 > 0:08:02with the fashion sense of a sausage.
0:08:02 > 0:08:07We need to freshen up his dated look and make him feel like 1 million.
0:08:07 > 0:08:09Work it, Colin. Own it!
0:08:09 > 0:08:12Yeah, baby. That's the look.
0:08:12 > 0:08:14Oh, stop it! This is all wrong.
0:08:14 > 0:08:16- BELL - Positions!
0:08:18 > 0:08:20Welcome back. Lynn got in touch to ask
0:08:20 > 0:08:23"So what is hair exactly and how does it work?"
0:08:23 > 0:08:28Our skin contains over 5 million tiny openings called hair follicles.
0:08:28 > 0:08:31Inside these follicles, hair cells work together
0:08:31 > 0:08:33to produce the hard protein, keratin,
0:08:33 > 0:08:36which forms the hair shaft that grows out from the root.
0:08:36 > 0:08:38Oh, don't talk to me about roots!
0:08:38 > 0:08:40The root is the living part of the hair
0:08:40 > 0:08:42and it's connected to blood vessels,
0:08:42 > 0:08:44nerve endings and other glands
0:08:44 > 0:08:45that help it function.
0:08:45 > 0:08:48Well, we all need a little help from time to time.
0:08:48 > 0:08:50But by the time the hair has reached the skin surface,
0:08:50 > 0:08:52it's made up entirely of dead cells.
0:08:52 > 0:08:54Which leads us conveniently to...
0:08:57 > 0:09:01So, Dr Knowles, why doesn't a haircut hurt?
0:09:01 > 0:09:04What the...? Well, the answer is quite simple.
0:09:04 > 0:09:07There are no nerve endings in the dead part of our hair,
0:09:07 > 0:09:09so we don't feel anything when it's cut.
0:09:09 > 0:09:11But it does hurt if we pull hair
0:09:11 > 0:09:14because we're pulling out all the little nerves inside the roots.
0:09:14 > 0:09:17- See you next time on Brain Freeze! - Toodle-oo.
0:09:20 > 0:09:23- Hey! Where's Colin? - I'm in here, Dr Knowles!
0:09:23 > 0:09:27I'm just putting the finishing touches to my new look.
0:09:27 > 0:09:32- Ooh, let's see, let's see! - Very well. Prepare to be amazed!
0:09:33 > 0:09:36But... Em... What happened to... ?
0:09:36 > 0:09:40I decided, Dr Knowles, that I'm happy just the way I am.
0:09:40 > 0:09:42You know what, Colin, you're right.
0:09:42 > 0:09:46Well, perhaps just a hint of styling cream.
0:09:46 > 0:09:49Beekeepers' ball, here I come!
0:09:49 > 0:09:51Oh, honestly, Dr Knowles.
0:09:51 > 0:09:54Some people just don't know style when they see it.
0:09:54 > 0:09:56Argh!
0:10:06 > 0:10:09# Brain Freeze! #
