Yes, you are to keep your teeth in contact while mewing(keep them lightly together). Proper bite. Yes. No, this is why  your teeth are supposed to be in contact.  https://tmdocclusion.com/ , this is a debateful question. 

I hope for the best of you. I think it's amazing of you to record your progress.

Mewing stop hair loss? I really think we are going too far on what mewing can do....

I think we need to stop claming impossible achievment and results. This is very dangerous because once people  will realize that certain results are impossible to achive they could fall into the trap of cosmetic surgery, then depression, BDD up to even extreme consequences. I invite everyone, even the forum admin to moderate more the enthusiasts and less the skeptics. This forum had a great potential but now it's just starts to scare me. 

Thank you, Fred. I have been taking progress pics with my back and head against the wall, I hope thats okay. I will be taking these pics in the same lighting every month whenever possible. I appreciate the answers, have a good day. :)

I meant not only mewing but proper body posture, if that wasn't clear, Martinez. Since there are no negatives to improving body posture and mewing properly( as far as we know), it doesn't hurt to try them and see the results. 

try eating healthy, doing sports (preferably cardio) and working out/sleeping enough. your hair will grow back and stop falling out. make sure you don't pull on them too hard while styling/brushing etc. and massage your head daily with your fingers.

Its difficult to maintain all that in college life, atleast for me, but I will try, alfons. Thank you for the advice. I have had a bad sleeping pattern the last few years, that may have played a role in my hair loss.

My hair used to shed quite a bit when I used to massage with my fingers but I will try again now, with all the other things I am doing right now, maybe it might help.

Of course you have been clear. Mewing and good posture goes together this is what Mike Mew always said and this is practiced by everyone one this forum, but if you think your hair will regrowth by correcting your body and mouth posture you will be disappointed.

The causes of hair loss are well known and there are specialists who can identify and treat (where possible) the causes of the problem. The risk is to waste time with ineffective solutions when you could solve or limit the problem with a traditional approach.

With this, I absolutely do not want to change your mind, it's not my purpose. If you think that oral and body posture will regrow your hair, ok, but I feel the need to warn other users that this practice are nonsense and that if they have a real problem of hair loss timing is crucial. Before the actual cause of hair loss is identified, before you can prescribe a proper treatment, the more likely it is to slow down or stop hair loss. If you intervene incorrectly or do not intervene at all, you may find yourself bald within a few years or months.

Misinforming people can be very dangerous for their physical and mental health.

Wish you the best with your Mewing journey.

 

Questions

• Should I keep my teeth in contact while mewing? 
• Should I mew with proper bite or with my overbite (placement of jaw)? 
• I've read it's normal for my airways to be blocked while mewing. Will there be a time in the future I won't have problems breathing while mewing?
• Do I have to worry for my upper palate width to increase in such a way that my lower jaw will look slimmer than my upper jaw, and my teeth wont be able to touch?
• Is it possible for my hair to improve over time now that I'm practicing proper posture, as it would improve scalp circulation, therefore amplifying the effects of the hair supplement? (1)

Most of these questions are kind of intertwined with each other: on one hand, in order for your mandibular arch to keep up with the expanding upper jaw, it would be good to keep teeth in light contact as much as possible. On the other hand, keeping teeth together when the occlusion is unfavourable can temporarily aggravate the health issues that the poor jaw positioning was already causing (which can indeed include hair loss), until cranial structure is improved. Experiment with jaw positioning to see what works out for you. For  postural correction, temporarily jutting mandible forward is often helpful.

Hair loss overall is a multidimensional issue where several unique and/or intertwined dysfunctions play out. Posture, hormones, cranial structure, stress, all of these influence each other to certain extent. What in particular is the root cause of hair loss varies from individual to individual, but there is no doubt in my mind that for some this cause is craniofacial dystrophy. The possibility of CFD-induced trigeminal nerve hypertonicity and subsequent hormonal-metabolic changes due to overaccumulation of a neuropeptide called "substance P" is explained in the following illuminating excerpt from a document @futuremodel shared in this thread:

It is my belief and clinical experience that the primary mechanism by which stressed bites impact health is by way of increased trigeminal nerve tonicity, which leads to elevated substance P .The trigeminal nerve has on average 100 times more dense “C fibers” than any other nerve. 
Other known mechanisms exist that could account for bite impact on your health are :

2-Jaw position influence on head posture,
3-Interaction of trigeminal nerve and upper cervical nerves (both go to same nucleus in brain (i.e. upper cervical is primary basis of chiropractic systemic theories),
4-Trigeminal vagal reflex,
5-Trigeminal vascular system (influence of trigeminal on brain blood flow),
6-trigeminal reticulo thalamic track (ascending sensory signal modulated by trigeminal nerve=why bite the bullet works), trigeminal influence on reticular activating system (ADD, ADHD, sleep disturbances),
7-Trigeminal proprioceptors influence on sympathetic nucleus in brain (dysautonomia, anxiety disorders),
8-Second order trigeminal proprioceptors influence on reticular formation (impacts sensory processing=movement disorders, cognition, diabetes, hyper and hypo conditions==leads to loss of homeostasis). 

There are more mechanisms but substance P is the main one. Substance P is a compound that few doctors know about.  Discovered in 1931, substance P has been researched extensively since 1980.  It is in fact a neuropeptide, a type of neurotransmitter that does not have a re-uptake mechanism.  So when secreted, in lingers in the body and has endocrine like side effects.
Its primary effect is that it opens up cell membranes, leading to loss of cell potential.  This causes the cell to become hyper sensitized (fibromyalgia, seizures,hyperacusis, photophobia, etc.) This allows viruses to invade cells (HIV), bacteria (Lyme disease), and calcium influx (cancer, chronic fatigue), as well as the cell’s insides to leak out (inflammation, leaky gut).  The scary thought here is that long term Substance P elevation may be a major factor in many types of cancer. Substance P is a known major modulator of bone metabolism (osteoporosis), stem cell differentiation (anemia, leukemia), neurocrine modulation (hypothyroidism, estrogen dominance, growth hormone imbalance), and movement modulation (Tourette’s, dystonia, Parkinson’s, tics, restless leg, gait disorders).  Substance P is a known major factor in drug addiction, alcoholism, depression, anxiety disorders, etc.  Substance P is known by researchers to be the primary mover in nausea, vomiting, migraine, asthma, allergies, and most skin disorders. 
Conceptionally, in a simplistic model, Substance P is the most primordial sensory system in the body, and all body functions rely on it foundationally.  So when its levels are off, most systems in the body go awry.  It impacts cell function dramatically which is the primary functioning unit in the body.”

With this in mind, it's not hard to see how mewing could, in the best case scenario, stop hair loss for some individuals. Whether or not reversing craniofacial dystrophy is enough to reverse hair loss would likely depend on the metabolic vigor of the individual in question, and how recent his hair loss had been. Areas of the scalp that have been bald for years will likely have poorer outcomes.

Do you experience other symptoms associated with trigeminal hypertonicity?

for hair loss try finesteride. it works wonders

I'm sorry for the delay!

Thank you for the detailed reply.

I am thinking of placing my mandibular arch in such a manner that most of my teeth remain in contact while mewing.

That post you linked was an informative read. Regarding trigeminal hypertonicity, I have chewed a lot of gum in the last few years, on some occassions for hours on end, maybe that counts?

Also, I've had terrible neck posture, like in that one video Dr. Mew describes how some individuals with slanted mandibular arches jut their chin out, making their jawline more parallel to the ground.

Hard to say, but I wouldn't say it's impossible. Chewing with recessed jaws can stress masticatory muscles like temporalis, creating chronic tension that constricts bloodflow. One of the major arteries supplying blood to the scalp goes across the temporalis muscle:

It's noteworthy that the areas direct on top of the temporal and occipital arteries are the least likely to go bald.
