What if our hair never stopped growing!!! OMG!!

Hello welcome back all my

Hello welcome back all my Theorist to another What If Theories and in this episode we take a close look at Hair. Well more specifically how does hair grow? Have you ever thought to yourself I better make it to the barber my arm hair is too long...well while some of us do have long arm hair the fact is all body hair does stop growing. but What if it didn't? The Image of my favorite Wookie comes to mind however does Chewy get a hair cut all over? I mean it's actually part of a natural system that works really well for all animals and Humans that all hair stops growing at a certain point. Wolves don't need to get a hair cut it just naturally stops and the same goes for all other animals other wise we wouldn't be able to see our beloved pets as they would

all be giant chia pets. Or Han Solo would would have serious hair issues on the Falcon. Seems only Humans have a need for a barber as hair on our head is a slight exception to this rule and keeps growing for much longer but does eventually stop.

So hair actually functions in 3 stages the first stage is the Anagen phase or Growth Phase. Depending on the type of hair whether it's leg, eyebrow or your Head will determine the length of this first Anagen phase. For our eyebrows this phase is extremely fast only lasting about 45-90 days to stop growing while the hair on your head will continue to grow for an average of 2-7 years. The length of the Anagen phase is believed to typically be tied to genetics but other factors such as hormones and nutrition will have a big deal to do with what is going on in the hair folicles. With that being

said in extremely rare occasions the hair on someones head can sometimes have an extremely short Anagen phase leaving them without having to have an expensive Barber bill. Also with the tails of repunzel on extremely rare occasions the Anagen phase for hair can last over 10 years. Some of these extreme cases of different Anagen phases are ZHENG SHUSEN with world record 7.5 inch eye brow hair.

How Anagen phase works is where blood flow at the base of a hair follicle produces oxygen and stimulates specialized stem cells that begin to divide and grow forming keratinocytes that form the base of the hair. As the keratinocytes expand pushing their way to the surface of the skin the cells die releasing a protein called keratin which holds the strand of hair together. So when the hair finally breaks the surface of the skin the hair exposed is actually dead

thankfully which is why we don't experience pain when our hair is cut. Can you imagine Chewy getting a hair cut if it hurt. Poor chewy. Which brings us back to what we probably would look like if our body hair had a longer Anagen Phase. We would all be wookieish. Well thankfully as we evolved our ancestors only held onto Longer Head hair growth.

The second phase is the Catagen phase which last about 2 weeks where the Blood flow is cut off from the keratinocytes sites meaning there is no Wookie for us and hair growth has stopped. Then shrinking the follicle to a 6th of it's original size then pushing the remaining hair strand to the surface.

The third phase is Telogen or resting phase where the folicle remains dormant for 1-4 months. 10-15% of one's hairs on your head is in this phase at any given time. Finally the hair sheds and is released when the follicle diallates again starting the Anagen phase all over again. There is possible hope for our

aspiring Ewok's or Wookie hopefuls. Depending on how fast hair grows in the Anagen phase and how long it last will depend on your final hair growth. So with some lucky genetics, proper nutrition and hormones you are on your way to your favorite convention winning first prize..... As always thanks again for
