We asked a dermatologist to explain the scientific reasons that some men aren't able to grow thick, dense facial hair. Dr. Jennifer Chwalek is a Board Certified dermatologist at Union Square Laser Dermatology in New York. Chwalek explained that an inability to grow thick facial hair is not directly related to low levels of testosterone. Facial hair growth is largely determined by genetics, which can determine the number of hair follicles a person has, as well as how the follicles react to a byproduct of testosterone known as dihydrotestosterone. ------------------------------------------------------ #Beard #FacialHair #ScienceInsider Following is a transcript of the video: Narrator: Look at that beard. The density. The thickness. It's what a beard is supposed to be! Not this. This is my beard, if you even want to call it a beard. This footage was taken after I let it grow for two weeks. Two weeks! It's thin, patchy, and in some spots there's no hair at all. Sad. But let's look at this one again. This is Kevin. We're around the same age, both Caucasian males of Irish descent. You could say we have a lot in common, except in the facial hair department. So, I asked a dermatologist about why he's able to grow a beard and I'm not. Dr. Jennifer Chwalek: It's based on genetics as well as hormones. Some men, you know, have more hair follicles, so they can grow denser, coarser beards than others. Testosterone gets converted in the hair follicle to a more potent form called dihydrotestosterone. Some hair follicles have receptors on them that are very sensitive to this higher form of testosterone, dihydrotestosterone, and that will stimulate hair growth. Graham Flanagan: How would you characterize my facial hair? Dr. Chwalek: I'd say it's like, sparse, and you have light-colored hair, so it doesn't show up quite as much. Flanagan: I can't really grow a great beard. It's been a problem. I want one. I wanna look like my colleague, Kevin. I mean, look at that beard. It is just glorious. Why can't I grow a beard like Kevin? Dr. Chwalek: Well, Kevin has some good hair genes, so because of that, the hair follicles on his face are more sensitive to the effects of a form of testosterone called dihydrotestosterone which can help to stimulate thicker, coarser, longer hair growth in some areas of the body like the beard area. Narrator: Beards and facial hair have long been associated with masculinity and virility. I began to wonder if my inability to grow thick facial hair like Kevin makes me less of a man. Flanagan: Does the fact that I can't grow a beard, does it make mean that I have low testosterone? Dr. Chwalek: No. Men who can't grow a beard or have patchy beards usually have normal testosterone levels. It isn't a reflection of having low testosterone or being deficient in testosterone. Flanagan: So, you can still be virile — Dr. Chwalek: Right. Flanagan: And grow a crappy beard like this? Dr. Chwalek: Yes. Flanagan: Okay, good. Narrator: And in fact, there are some ways to increase the chances of growing facial hair, but shaving more often isn't one of them. Dr. Chwalek: So, the idea that shaving can impact hair growth is actually a myth. When you're shaving, you're just cutting the hair off at the surface of the skin, and what's controlling the hair growth is really occurring deeper in the skin. So, it shouldn't have any impact on how quickly the hair grows, or how dense the hair grows. People have tried topical Rogaine or Minoxidil. These things may stimulate a little hair growth, but assuming it's due to genetics, then you're kind of stuck with what you have. Flanagan: It's all about the sensitivity of the hair follicles and how they interact with this — Dr. Chwalek: Dihydrotestosterone or androgens in the blood. Flanagan: So, you're saying that, that his hair follicles are "sensitive." Dr. Chwalek: Yes. Flanagan: See, mine aren't. Dr. Chwalek: Right. Flanagan: They aren't sensitive. They're like rocks. They have no sensitivity at all. Okay, so I win that! Dr. Chwalek: Right. Science Insider tells you all you need to know about science: space, medicine, biotech, physiology, and more.

http://www.matthewbey.com If you've ever wanted to watch paint dry, you can now do it in half the time through the wonders of time lapse. I stumbled upon Space Squid contributor David Johnston as he was in the middle of an experiment in layering of patina. Because of the 94-degree Texas sun, it didn't take all that long for the transformation to occur. Paint dries quick in Austin.

How a cheesy joke from the 1830s became the most widely spoken word in the world. Subscribe to our channel! http://goo.gl/0bsAjO OK is thought to be the most widely recognized word on the planet. We use it to communicate with each other, as well as our technology. But it actually started out as a language fad in the 1830’s of abbreviating words incorrectly. Young intellectuals in Boston came up with several of these abbreviations, including “KC” for “knuff ced,” “OW” for “oll wright,” and KY for “know yuse.” But thanks to its appearance in Martin Van Buren’s 1840 presidential re-election campaign as the incumbents new nickname, Old Kinderhook, OK outlived its abbreviated comrades. Later, widespread use by early telegraph operators caused OK to go mainstream, and its original purpose as a neutral affirmative is still how we use it today.

So I spent a year learning to play the piano. This video - the result of probably about 350-400 hours of practice - doesn't even come close to some of the one-year progress videos out there, but I'm putting it up here as a record of my progress, and hopefully to inspire someone else to take a leap into starting something they've always wanted to do. I messed around with a bunch of different songs that I couldn't include in this video, and I'm planning to continue tweaking everything I worked on - as you can probably hear, my tempo and dynamics need work even on the stuff I can 'play'. I used a bunch of resources, but some of the most useful were: Jane's Piano (YouTube channel) Andrew Furmanczyk (YouTube channel) Alfred's Basic Level 1 (https://amzn.to/3KG6WOI) My keyboard is a Roland FP10: https://amzn.to/3ejmeg7 (Disclaimer: These are affiliate links, I'll a commission if you buy the book or piano from them. No extra charges are made to you. Thank you!) I practised scales pretty much every day that I sat at the piano for at least the first eight months, and added in arpeggios and chord inversions after that. I also started reading music from my first day, although I didn't practice that as much as I should have - planning much more of it over the next year. If you've got any more questions about technique/songs I learned, etc, please hit me up in the comments - and please subscribe to see future piano projects!

It is time to take a closer look at some foods that are often said to be radioactive: bananas and brazil nuts. How active are they in reality? And why would they even be radioactive in the first place? Can I find something way more active and still edible in a grocery store? Let's find out!

Why are men obsessed with beards? Do women even like beards? In this video, we explore why women are indifferent to beards and why men love them so much.

When the engine cools down completely and exhaust gasses exit the combustion chamber, condensation of water and carbon dioxide can be noticed much more, and in a moment like this, you notice water dripping from your car's exhaust pipe. This is completely normal and you don't have to take your car to a professional. #Mustang #Exhaust #Water
