World’s Most Asked Questions: How Do I Grow a Beard?


[Intro] A lot of people have a lot of different questions,
and sometimes those questions line up so that a lot of people have the same question. And
people ask the internet for answers to these questions like “Why are tears salty?” or “How
do I get rid of bedbugs?” or maybe just “How do I see more cat videos?” We’re all about fostering curiosity here are
SciShow – that’s why we’ve worked with Google and YouTube to answer 10 of the most googled
questions on the internet. This is The World’s Most Asked Questions. Today’s question: “How do I grow a beard?” Well I can’t really help you sprout a stylish
Van Dyke or a bushy Shenandoah or a Lincoln-esque chin curtain, but I can explain the science
of facial hair; all you need to have for a big, bristly beard are two things. First: testosterone. Both males and females
produce the sex hormone testosterone, but the highest levels typically occur in males
who have reached sexual maturity. Testosterone is responsible for all of the secondary sex
characteristics you generally find in men, like more muscle mass, more body hair, and
an enlarged larynx resulting in a deeper voice. It also triggers the growth of facial hair. But the whiskers don’t just show up out of
nowhere; testosterone actually interacts with the little wispy peach-fuzzy hairs that everybody
already has, pigmenting them to make them darker and stimulating them to grow thicker.
But make no mistake, the bushiness of a man’s beard is not a measure of how much testosterone
he’s producing. Lots of research comparing men across various ethnic groups found that
guys who produce less facial hair have the same hormone levels as those who look like
Duck Dynasty stand-ins. So what else do you need? The right genes. ‘Cause it takes two players to make a whisker
after all. The testosterone and the follicle, or sac in the skin where the little fuzzy
hair grows into a thick bristle. But the thing is, not all follicles respond
to testosterone’s chemical signal in the same way. Genetic variations can change your follicles’
sensitivity to hormones; as a result some guys’ hairs have a hard time reading and responding
to the signal, resulting in your kinda patchy Bob Dylan scraggle. While others are really
sensitive to the hormone, giving you your Sacha Baron Cohen types. So just as the hair on your head is a certain
color and texture depending on your genes, so is your beard, or lack thereof. Finally, a tip that might save you some trouble:
shaving really does not make your beard grow faster! We’re not sure how that myth got started,
but it probably has to do with the fact that hairs are long and tapered, coming to a narrow
point at the end. When you shave off the skinny top of the hair, you leave the thicker lower
part exposed, making it look a little bigger. But your whiskers won’t grow in any more full
or lush because you shaved them. Like it or not, you’re stuck with whatever
your face can produce; for me it’s mostly just…right here…ughh. Unscientific survey analysis time: SciShow
Space watchers, according to the survey, were way more likely to have beards than people
who don’t watch SciShow Space. Now that seems really weird until you realize that SciShow
Space viewers also are much more likely to have Y chromosomes, and thus a lot more testosterone,
which is why statisticians are important. Of all the fascinating questions in the world,

  1. When they grow em I suppose to feel the groath? It kinda felt good like if it was dopamine but on my skin.

  2. Yeah I didn't gor any facial hair until I was 19, my father and brothers told me not to worry and that we all grow our facial hair in our 20s, sure enough my brother suddenly started growing a full beard in his late 20s and I started with a light moustache to more defined moustache and a bit of hair on my chin which also happend very fast. My 3 brothers and my father can grow hull beards so I am not as scared anymore.

  3. Easy. Increase the amount of androgen receptors in your upper layers of your skin and the amount of dihydrotestosterone in your body. In some way.

  4. Im ten years old and my sister sayin that im growin a beard alot of times if u shave u grow beard faster but im stupid so now i am growin a beard hopefully what my sister said was true because i want a beard i sound stupid so iml shut up now

  5. since my southern ancestors are British–I have been able to impersonate St Nick since I was a teen–although the beard was strawberry blond

  6. Better question. How do I stop a beard forever? They are gross and horrible and need to go away, never come back, and preferably our species should loose the trait entirely. It's just gross and makes you look like a homeless bum looking for some feces to flavor your rat stew.

  7. If I could grow as much hair on my face as I do on my ass I’d be in good shape. Also my facial hair is red and the rest of my hair is brown, why?

  8. The question I want most to know is Why was this in my recommended for weeks?
    and will it stop now? ……. Please?

  9. Most asked questions:

    1. Why are there white people that are racist to blacks?

    2. Why do people prefer whiter skin when they produce the least amount of melanin and sunburn terribly?

  10. he is TOTALLY wrong. First of all testosterone is not the one that grows facial hair. It is Dyhidrotestosterone. To increase the amount of it here's 1 tip:
    -Stop masurbating.

  11. My brother has the longest beard on earth because he works in passport things he says if you have a beard people are more scared than you having a clean shave.

  12. What if you scrape you're facial hair on concrete or sum does it grow normal or be more difficult to grow I know this is an old video but it would help me out allot due to the fact that I'm dealing with this

  13. I think scruffiness is unattractive. A clean cut well dress man is better looking then a scruffy one that has a beard. This is my preference and personal appearance. Someone who has scruffy beard on there faces it points out that someone doesn't take care of oneself and personal hygiene. A clean cut guy is more attractive then a scruffy beard guy.

  14. I was about to skip this video but then he mentioned the Y chromosome and my whole entire world changed! My whole life has just changed Y CHROMOSOME!!!

  15. wow…ok, I thought the number one question would be, "Why does god allow horrifically awful things to happen to good people, like innocent children and babies??"….guess I was wrong…

  16. My dad had a beard my grandfather had a godly beard
    Even my mother's father had a full beard and I'm about to turn 20 now and still don't have it , tf is wrong with me

  17. This can change over time too – couldn't really grow more than a thin moustache and chin patch until mid 20's, since that time it's slowly become a bit thicker as time goes on…

  18. And I'm hear asking how to permanently get rid of it as facial hair, then again any bodily hairs really, is very annoying to me lmao.
