Healthy Hair Isn’t What You Think… Hair Science!

Healthy Hair Isn’t What You Think… Hair Science!


We talk a lot on this channel about
healthy hair, but you might not even know exactly what healthy hair really means,
so we’re gonna talk about that now. Hello and welcome to the Queendom. I’m Sarah Ingle and today we’re talking about hair health and we’ve been, in case it’s your
first time here, on this mission to find the best and worst hair care advice on
the internet which means we’ve been doing a lot of reaction videos to a lot
of places we know is good they’re gonna have terrible advice like Troom Troom,
5-Minute Crafts, and Brightside. They tend to just have garbage advice and we
know it but we know it’s gonna be funny to react to it so we do it because if
you can understand these things we’re gonna talk about today
you’re gonna have such an easier time taking care of your hair so we’re gonna
dive into some of that today I have spent so many hours and hours this week
been reading medical journals academic research articles I did all the boring
part for you so you don’t have to sit through that we’re gonna just dive in
and get the part that’s actually useful for us so that we can understand our
hair are the differences between our hair and really understand what hair
health means because before I did this research I sure had the wrong idea of
what it was so first of all what do you think of when you think of healthy hair
I think the picture that comes to a lot of our minds like is this thick shiny
like glossy smooth sometimes like long and flowing hair very like Pocahontas but that is not the only picture of what
healthy hair is for one we’ve got to start with one really big misconception
is the difference between thin hair and fine hair have some diagrams for later
but for now I’ve got sticky notes we’re just gonna draw some these little dots
there we go I’m going to stick this here um here it’s another person with ten
hairs this hair is thick hair even though the hairs themselves are very
small this technically could be thin hair even though the width of the hairs
are very very wide one thing that you cannot change is the number of hair
follicles on your head from the time you are a baby you have the same number of
hairs but different things can happen so you might not be growing hairs out of
all those hair follicles at any given time my hair in particular happens to be
very very fine there’s a lot of them so it’s technically thick and fine at the
same time and that is one of the biggest misconceptions that we hear all the time
people are like oh my hair is is thin what can I do about it and in a lot of
cases your hair isn’t thin it’s fine so the actual width of each hair is small
you can still have fine hair that is healthy and a lot of that the width of
your hair tends to be genetic and it tends to change with the type of hair
that you have and a lot of it has to do with certain ethnicities tend to have
wider diameter hairs than others especially different hair colors and
different hair colors also tend to have more hair follicles it’s just a lot of
stuff but first of all like just clearing that up right from the
beginning frizzy hair does not always mean unhealthy hair it can it can
especially for certain hair types like if you tend to have very thin straight
hair frizz is probably more likely to be a sign of damage but that you can have
perfectly healthy hair that is very frizzy and we’re gonna get into a bit a
little bit of that and why that is in a minute and there’s different things you
can do to prevent it from being force but just because it’s frizzy does not
mean that your hair is damaged a lot of old like very early like 1900s
hair advertising and stuff was meant basically for white women with street
hair and even the white women with curly hair were like there there was not
information out there for them for a long time we’re gonna take a little bit
closer look what is actually going on with your hair so but uh diagram it’s
actually possible to over here if there’s more space over here but
whatever it’s gonna go probably here you’ve got your little hair follicle and
you’re not going to increase the number of hair follicles on your head and just
basically just kind of shows you what’s happening with a single hair we’re not
gonna go into a lot of detail on this but I wanted to show you this so that
you see what’s happening all over your body the next slide has the cuticle on
the outside you can see the cuticle has all these little it’s like almost think
of them like shingles on and they’re like little flaps and they
can lick open and close kind of and certain things can cause them to open up
and when they’re open can make the inside more vulnerable to damage because
it’s exposed or sometimes we need to let things in there depending on what we’re
trying to do with our care I think we all new things we hear things about hot
water it makes it open up and then cold water closes that we’re gonna bust that
myth sorry I die this is when I heard a lot in the comments and someone’s still
probably gonna come at me but I’ve got by the way linked in the description
links to a ton of different medical and scientific journals that go into like
the sources for all of this in case you’re curious so so basically you’ve
got the hair shaft moisture makes the hair shaft swell up and then the cuticle
opens all the little doors up when it swells and some certain products are
designed to open it up even more depending on what you want to do with
your hair as what allows us to to style our hair to change things about it to
straighten it to curl all sorts of different things because you got to open
it up to get to the inside water that’s coming through your shower a lot of
waters are not at a good pH level that you get automatically through your
shower for your hair and it can cause a lot of extra frizz water doesn’t open up
the cuticle as much as some of the pH balance stuff it can cause extra damage
to the hair I actually have a showerhead that filters that out and gets the water
it filters out of us that that’s really bad and I think it’s s’posed to pH
balance it I think that’s part of what it does that keeps it from opening up
the cuticles so much so it keeps your hair a little bit more protected so now
really something super interesting that I think I’d heard it before but I didn’t really understand it. This is actually
really simple and one of the biggest like lightbulb moments if you just like
hang on for like three seconds what we talked about what that means
hair bonds it’s like what holds your hair together and there’s three
different types of bonds when you unbond the hair that is what allows you to
style it to either straighten it or curl it or basically change the shape of it
the three types of bonds hydrogen bond that’s the first type which basically is
water the second one is disulfide bonds or also known as S bonds it’s initialed
with an S and the third one is salt bonds it’s the salt they’re after we’re not really gonna talk much about here because most of what we need to know is
the the first two so hydrogen bonds are the most flexible. if you get your hair wet
you can style it and the hydrogen bond can actually rebind itself because it’s
the most flexible one of the three so that’s what allows us to get our hair
all wet put it up in rollers and as it’s drying it’s rebonding basically and then
it bonds in the shape that it’s held and so then when you take it out when it’s
all dry it stays in that shape until it gets wet again or it gets heated up
because he is the other one that can can break that particular bond
the thing about hydrogen bonding with heat and water it is temporary and you
know that if you think about it like obviously if you straighten your hair
and then you go take a shower it’s not gonna be straight anymore the same thing
that allows you to style in the first place allows you just style it again so
it’s really not that complicated so the hydrogen bonds are responsible for about
30% of the hair strength and about 50% of the elasticity which by the way
elasticity is something that is a really good
measure of how healthy your hair is so basically if you take it depending on
how if you can pull on it and it’s kind of got some elasticity to
it that is a sign of healthy hair if you’re getting ahead of me a little bit
here and starting to think what the hydrogen bond and the water thing means
you might have already started to figure out why certain types of hair frizz but
before we get to that I want to talk about the disulfide bonds and disulfide
or s bonds sounds really scary but it’s basically another type of bond but
what’s different with than the hydrogen bond is that once that bond is broken it
does not read bond disulfide bonds are the strongest type of bonds and only
chemicals can break them if you get a perm or you get your hair relaxed
something that it’s chemically done to your hair to change the shape of it
that’s not just water or heat and then there’s salt bonds which are basically
broken by pH changes we’re not gonna go a lot into that but I think had to do
some with like shampoos and stuff and now that we understand a lot more about
how our hair works we’ll just talk about one other thing and that is how your
hair grows and the phases of growing there’s like four different phases of
hair growth you have Anagen, Catagen, Telogen, and Exogen the names of them
obviously you’re not gonna be tested on this it’s not like you’re gonna break it
down and remember but basically those are the four types Anagen is your
growing face my goodness girl on your heads like the hair that grows out of
your head that is about 2 to 7 years typically a hair is in that phase
growing and growing and then we have catagen or the second phase is kinda
like this transition phase it lasts about 10 days during those 10 days that
is when the hair follicle shrinks up and detaches from the dermal papilla papilla i don’t know how to say it but i know how to read
so the third phase is the resting phase your little hair follicle is taking a nap. this lasts for about three months and at any given time about 10 to 15 percent of
your hair in normal cases is in this phase just resting and there’s no hairs
growing out of the hole where a hair could be growing out if your hair enters
this phase too soon for some reason that is when your hair can start to thin and
you don’t have as many hairs growing out of your head as you normally should be
and then we can move on to our last phase of hair the Exogen phase and
basically that’s the new hair phase so the old hair just sheds and it’s totally
normal for your hair to for you to shed anywhere between like 50 and 150 hairs
per day obviously if you’re shedding a lot more than usual that signifies
there’s something wrong if you have severe hair thinning it’s probably not
because of something happening putting on the outside of your hair because that
would happen more down here because everything once it comes out of your
scalp that hair is dead it’s not alive this is dead it’s only like in the scalp
inside like the dermis under your epidermis where things are alive and and
and doing things once it’s out here it’s dead
when your body is not getting especially if it’s not getting all the nutrients it
needs or something is wrong it is very smart it goes and focuses all of its
resources on essential things to your life and hair is not one of those so if
it’s having to divert resources basically if you’re not getting the
nutrients you need it’s going supply those nutrients to your vital
organs before it’s going to supply them to your hair and so that is when you can
start to lose hair so hair starts on the inside and comes up outside once it’s
outside of our head there’s things we can do to take care of it
but once that cuticle is damaged there’s nothing we can really do for it to
regenerate itself there’s things we can do to keep on it like keep it protected
to keep it smooth to keep it looking nicer even if it is damaged but it
cannot be regenerated like our body heals like if we get cut or something
like that because this is just basically a bunch of protein wrapped in a little
shell so kind of bringing this in fact to hair health and what healthy hair is
we talked about elasticity but we also talked about the myth that frizzy hair
means damaged hair and it doesn’t always especially in the case of people with
very curly hair and I’m going to provide some examples here for you my mom insert
picture my mom now basically every day blow dries her hair straight she or if
you in your case if you have curly hair and you straighten your hair what you’re
doing is you’re breaking that hydrogen bond and you’re letting it rebonds
straight and so now your hair is nice and straight but because that is not the
natural state of your hair if you walk it out in the humidity
the second humidity hits it what is humidity it is moisture in the air that
is hydrogen that is unbinding that so that is basically when you’re using anti
frizz products it’s basically trying to block the the hydrogen atoms from coming
in from the moisture and on bonding that hair which causes it to frit my hair in
particular I feel like I got lucky in a way it never gets like – I can get
frizzy but not like my mom my mom’s hair literally just poof poof but then my
dad’s side of the family has the tiniest finest hair imaginable so I think we
almost kind of need to rethink what we think of as healthy hair and what things
we do to point out at people so every now and I’ll get somebody who’s like
well your hair obviously isn’t healthy because there’s frizz yeah because I
don’t have straight hair so it can frizz like that’s just a fact if I had never
touched it and it was perfectly healthy it can still frizz my hair I tend to
prefer the look when I am in a very humid place because the extra you get
the frizz honestly that kind of sometimes happens in here gives me some
extra volume just makes my hair look more like ooh if it’s a thing it’s a new
thing we we have so much like this marketing pushed at us where your hair
has to be this glossy like sleek no it doesn’t really have to be it’s perfectly
natural for there to be some amount of frizz I guess what all this boils down
to is one we got a mind our own business do your hair the way you like to do your
hair do your thing I’ll continue doing my thing and secondarily if you want
thicker hair by the definition of what thicker is it’s probably an internal
thing just make sure you’re taking care of your body giving your body all the
proper nutrients that it needs and your hair will be more likely to to be
growing out at its maximum potential we’re born with like our baseline I just
kind of acknowledge that baseline and if you’re treating yourself really well I’m
really healthy that’s gonna be the best way you just keep your hair healthy
understand what’s happening you with your hair because I think understanding
what’s happening with your hair is a really good first step into taking
better care of it I know we had a lot science hair science throwing it to you
so if you made it this far congratulations so I want to hear it
from you guys in the comments below if you have a straight hair or wavy hair or
curly hair anyways if you guys want to continue with me on my hair journey a
different type of hair journey a lot of people’s hair journeys like let’s my
hair get longer no we’re on a journey to educate ourselves so that we know when
somebody’s lying to us about our hair and a lot of times they don’t need to
lie to us they just do because there’s not a lot
of good information so if you guys want to see more videos like this Marvin
about hair lifestyle beauty and also we’ve got a magical twist quite a bit
Disney stuff sprinkled in remember to subscribe we put out new videos every
Monday Wednesday and Friday so ring the little bell if you want those to come
right to you thank you guys so much for watching hope your hair is happy for
watching and I’ll see you next time umm won’t let this hair tickling me actually
speaking of hair oh I’m so sorry to anybody who hates the whole the whole
thing just look away for a couple of seconds if I’m sorry I’m sorry this is
just one of those times where you’ve got to draw dogs maybe chic simple shake
some boats rock boats earthquake you it’s not a big thick hair and fine hair
they’re hammering again okay this oh boy the hairs different that grows out of
your head obviously then it grows out of your face on your face it’s very very
fine and we’re all fine with that I’m not fine with the amount of hammering
that is happening below me it’s like trying to fill

  1. yes!! i love your hair videos!! i’ve been straightening my hair for years & i’ve finally started to slow down on it because of you and your videos! :)) do you think you’d ever do a video on how to straighten your hair without using heat? (is that even a thing lol) ❤️❤️

  2. Yes!! I love this hair series! Plus, I'm trying to grow mine out and figure out how to take care of it so it's really helpful and the videos are coming at the perfect time

  3. 5 minute crafts: lady puts eggs in her hair
    Me: Laughing when imagining how she's going to tell the doctors how she got salmonella.

  4. I'm getting a protein tomorrow (protein is like a perm but makes your hair straight instead of curly) and it re rebuilds damaged hair and I'm cutting some thickness out of it cause it's sooo thick and curly and frizzy , so this really helped I've been struggling with my hair all my life but when I started putting time and effort into it, it started to grow more and become way healthier, if I prefer something is definitely getting a protein (you can search it up its really healthy for your hair)….. SORRY FOR THE LONG COMMENT

  5. All I've wanted sence I was very very young I've wanted long hair. When I was younger I had hair down to my butt and past. Then my younger sister cut it when she was like 5 and I was about 7 and we had to cut off a bunch of hair and it was about 3 to 5 inches under my shoulders and then I decided to cut my hair right above my shoulders for twin day and ever sence it has been really hard for me to grow my hair. I don't put my hair up tight and I take very good care of it it's been about 5 years sence I cut it to my shoulders it's grown less thank 8 inches. I was hoping you could give me some tips. My hair is a little frizzy and wavy. Plz tell me if you have any suggestions. 😊 Thx.

  6. i am getting a hair protein treatment on Saturday. i’m getting it because my hair falls out really easily and they know that i really want long hair. i don’t even remember the last time i curled/straightened my hair because that’s how much longer i want it. but thanks so much for the information! 💗💗

  7. If this were a hair science class I dont think anyone can hate this!Teacher Sarah, You may be onto something 🙂 I have straight hair the kind that keeps growing if you know how that is like. I do wanna know is, is it healthy or not to dye your hair often?

  8. Hi! You mentioned in the video, that you need nutrients to grow healthier hair. What products do you recommend?
