Surgical mesh.

Okay, hear me out.

I have a 3x3in surgical mesh square laid across my lower abs from a hernia I gave myself squatting at the gym. I’ve never had any issues with it and I’ve completely forgotten it’s there. It’s made of a combination of polymers, but mostly polypropylene.
They placed it by making two circular incisions about the diameter of a pea and pushing it through one like a Kleenex through a straw, then used scopes with spider claws on the ends through either incision to spread it out flat and sew it down.

This gave me a few ideas that all revolve around a custom made surgical mesh that is laid subdermally underneath the scalp. Now I’m a chemistry major and not a doctor-to-be, but my understanding of anatomy tells me that it would be possible for a long term mesh to exist beneath the dermis and nerves and above the skull. In fact, many brain surgery patients already have such a thing.

There are also metal meshes used in skull reconstruction like this. An alternative to surgical mesh could be a biopolymer device similar to the picture below.

My first idea was: why not just load that bad boy up with 5ARs and AAs like one of those arm bar birth control implants and have it radiate finasteride goodness into the follicles in close proximity. This is idea was quickly dismissed after I realized there’s no possible way to keep any of it from going systemic in large quantities, as well as the fact that they’d need to be replaced every 5-8 years. This led me to my second idea.

We know certain chemicals interact with other chemicals in many ways. Some are rendered inert and benign, some react with each other and some are highly caustic. What if we identified a type of biocompatible complex polymer that rendered the actual chemical of finasteride inert? Then what we end up with is the ability to bathe the scalp in retarded amounts of finasteride without worrying about systemic effects.
This is when we get to bust out the fun chemistry problems and dink around with calculus. Unfortunately, thus far I have not been able to come up with a compound or structure that:

A.) Is biocompatible
B.) has a strong enough affinity for 5AR2 and/or the related enzymes as to prevent “leakage”
C.) will react with finasteride in such a way as to catalyze it into a biologically inert compound
D.) will not erode in an unacceptably short amount of time

It seems likely at this point such a polymer does not exist, or at least would take a team of researchers with a large-ish budget to develop.
But in true American fashion - what if we improvise? This brought me to my current train of thought..

What if we would modify a current topical AA to break down when it comes into contact with the mesh? Either into something completely inert, or something that we can currently deal with with existing medication? Let me put it another way.

________________________________
Chemical A is currently used orally and topically to treat male pattern baldness, but it’s side effects are undesirable. When Chemical A comes into contact with our surgical implant, it is converted into chemicals B, C and D. The side effects of these chemicals are equally undesirable. However, another medication currently used to treat ailment X works by inhibiting and destroying chemicals B, C and D.
_________________________________

At this point it is fairly well established that the Wnt/β-catenin pathway is the key to stimulating hair growth. According to a few research studies (summarized by Sonthalia et. al here https://www.researchgate.net/profil...Transplantation.pdf?origin=publication_detail) certain chemicals such as valporic acid are conducive to activation of this pathway. We also know that at least one of the current treatments for male pattern baldness being studied by pharmaceutical companies combines Wnt/β-catenin activating compounds with finasteride, so we know it’s possible.

“Thus, an understanding of these pathways has clearly opened a new option of targeted treatments for Androgenetic Alopecia through the modulation of the Wnt/β-catenin pathway. This includes drugs like valproic acid and analogs like lithium chloride and beryllium chloride, which have been shown to induce hair regeneration in murine model and promote human hair growth in in-vitro culture model” - Dr. Sonthalia

Okay, but, what does this have to do with surgical mesh?
Well, we know valporic acid DOES react with certain polymers and it DOES get broken down into less potent byproducts. To what extent are those byproducts harmful to the human body? Are there any current medications that can counteract them? Will combining valporic acid with finasteride cause finasteride to also act this way? These are the questions.

What all of this boils down to is a three-part treatment plan.
A.) a surgical mesh implant
B.) regular topical application of a specific topical solution
C.) a once daily pill

This all came to me this morning while I was doing homework in the library. I’d love to hear from you guys. Am I being completely stupid here? Am I daydreaming? From a chemistry standpoint, I believe it’s possible. I’d love to hear from some of the more medically minded about their opinions on the physical aspects. I’m gonna try to get my professor’s opinion on this at some point this week. I also have a thesis due in like two years and this might just be unique enough to get me a good grade.

If any chemistry bros wanna slide in my DMs and get autistic about the math and formulas, please do.

Hope everyone is having a good day.

we just need P-3074 a finasteride that reduces scalp dht but doesn't go very much systemic. hopefully thats actually possible to make
According to their published results the DHT inhibition was less than oral finasteride but still massive :(

I wouldn't call 5% massive(they said 1/15th) but the thing is the study to my knowledge was only 1 week and systemic absorption takes a while
Perhaps we read different studies?

“RESULTS: Change from baseline in scalp DHT was -70% for P-3074 o.d. and approx. -50% for P-3074 b.i.d. and the tablet. Serum DHT decreased by 60 - 70%. The doses of 100 and 200 μL P-3074 resulted in a -47/-52% scalp DHT reduction, similar to the 300 and 400 μL doses (i.e., -37/-54%). A -5.6% inhibition was observed for the vehicle. Serum DHT was reduced by only -24/-26% with 100 and 200 μL P-3074 and by -44/-48% with 300 and 400 μL P-3074.”

who the f*** is going to surgically implant a mesh that rests on their skull for the privledge of using topical finasteride? That's just going too far and the market for it would be so miniscule. The development of such a device would probably take longer than a de facto cure anyway. I don't see the practicality..... its simply too invasive.

It would seem like it, but modern mesh implants are minimally invasive and take like 10 minutes in the OR. I mean.. I feel like most guys here would do it if it was an option. Women do much more for tit implants and nose jobs every day

sh*t, I’d let them cut off my scalp and drill on one of those titanium fuckers and sew it back on if it cured my baldness.:oops:

"
Androgenetic Alopecia is an androgen-dependent disorder, which leads to progressive miniaturization of hair follicles. It depends on an increased rate of conversion of testosterone into dihydrotestosterone (DHT) in scalp, through the action of 5α- reductase enzyme. Oral finasteride is an effective treatment for Androgenetic Alopecia, potentially associated with sexual side effects. A new topical formulation of finasteride (P-3074), vehicled in Hydroxypropyl Chitosan (HPCH) Technology, able to control the release of finasteride in hair and scalp, minimizing the systemic exposure, has been developed. A pharmacokinetic phase I study, tested P-3074 b.i.d. vs oral finasteride 1 mg o.d., revealing a finasteride systemic exposure 15 times lower in the topical formulation. A pharmacodynamic study compared P-3074 b.i.d. and o.d. vs oral finasteride 1 mg o.d. in DHT inhibition in scalp (vertex) and in serum. The results showed comparable serum/scalp DHT inhibitions across formulations, suggesting that the achievement of comparable levels of DHT inhibition vs the oral form could be attained by a lower dose of P-3074. A following dose-response study evaluated whether P-3074 lower doses could achieve consistent inhibitory effects on scalp DHT, minimizing the systemic effect. At doses up to 200 mcL, topically applied P-3074, allowed to significantly and consistently decrease DHT in scalp (comparable to oral finasteride)and only marginally in serum, potentially minimizing the untoward side effects linked to a systemic DHT reduction."

oOf that is some exciting sh*t right there brother

Sure, if it cured your baldness, but unfortunately current topical AA's do no such thing. Besides, this may complicate future potential hair transplants. I think some kind of Liposomal solution should be more feasible for most people. Some kind of solution that's suspended in the scalp and doesn't enter the bloodstream, but unfortunately i think the only reason treatments work in the first place is because of their systemic effects....
We need some kind of local androgen receptor antagonist, i think CB is the closest thing....

Respectfully I think you might be missing my point. What I am proposing is theoretical scalp DHT inhibition of 100%, which is an ipso facto cure. What prevents topical AAs from inhibiting DHT in large quantities isn’t the limitations of their formula but the systemic absorption.

I can’t comment on what it would do to a hair transplant though since I’m not a doctor, but a simple solution would be to get a hair transplant before this is done

Anyway I don't think that DHT droop itself is a problem, it is estrogen with is produced on higher level, because your body react on hormonal change. In some cases lucky ones, testostosterone level just jump up, and life you with higher libido, but in other, after some while(in my case 11 weeks) estrogen will be risen and that what is making typical side effect. Probably if we would take other steroids that inhibit estrogen, we would be good to go with f*****g finasteride, but I personally don't want to do that.

If i recall correctly, the polichem study only tested dht levels 1 week after beginning application, which is very suspect...... people are hypothesizing that systemic levels of Finasteride will eventually accrue on this treatment.

here is the study

https://www.ncbi.nlm.nih.gov/pubmed/26636418

METHODS:
Two randomized, parallel-group studies were conducted. Study I: 18 men received 1 mL (2.275 mg) P-3074, applied to the scalp once a day (o.d.) or twice a day (b.i.d), or 1 mg oral tablet o.d. for 1 week. Study II: 32 men received P-3074 at the dose of 100 (0.2275 mg), 200 (0.455 mg), 300 (0.6285 mg), or 400 (0.91 mg) μL or the vehicle o.d. for 1 week. Scalp and serum DHT and serum testosterone were evaluated at baseline and treatment end.


Is there anything more recent from these guys, where they measure blood markers over a longer period of time?

yeah phase 3 was 2 years. https://adisinsight.springer.com/drugs/800036658

it finished in march 2018 and they publish results within a year so they will be coming out soon. this could be great time if CB and this show effectiveness or a horrible time if they don't.

I think it’s likely Polichem will fall victim to the cumulative effect of finasteride. CB on its own however might not be a 100% cure but could still be a huge asset.

Hope I still have hair left :mad:

Actually this leads me to another thought.

Let's say that they're able to engineer a wonder topical that inhibits 100% of scalp 5ar2 and stays completely local. What then, stops the systemically circulating dht from 'floating' up into the scalp and attaching to the receptor? I know it's a massive oversimplification but its something ive pondered ever since ive heard about topical finasteride being trialed...

I think finasteride has a long half life in the dermis and coupled with the right vehicle could remain active between applications

Minoxidil is said to stay active for up to 22 hours in the skin

But finasteride inhibits the 5ar2 enzyme, it does not prevent the DHT hormone from docking to the receptor. DHT is still being produced within the body, can't it find its way to the scalp?

edit: i'm also quite wary of using serum dht as a reliable indicator, because we have 2 forms of 5AR, simply measuring serum DHT doesn't indicate which of the two enzyme's produced it. The reason this may be important is that 5AR most likely has other functions than just T ---> DHT conversion. Are there are other lab tests which directly measure 5ar2 activity....I know there are a few that measure overall 5AR, but im not sure if they distinguish between the two.... Is this just splitting hairs? If only Bryan were still alive, he would have definitely schooled me.

I believe the DHT that causes hair loss is converted almost exclusively in the scalp itself. Check me on that tho
