Out of curiosity, what is wrong with the solutions available today? I see Elon Musk before and after and his procedure appeared to have gone great. Is that just because he could afford a more expensive procedure?
Musk had a hair transplant, which is quite expensive and a quite involved procedure. The results are also highly dependent on how bald you are, the type of hair you have, and even the doctor who does it. If you accidentally pick a bad doctor your hair transplant can end up looking awful. It also doesn't make your balding stop, so you may continue balding and need another hair transplant in the future. Hair transplants treats the symptom of hair loss but not the problem.
The holy grail would be a pill or lotion you could take and truly stop/reverse hair loss. There are some existing pills (finasteride) and lotions (rogaine) but they don't work for many, and have their own issues as well.
Plus, your head looks like shit for at least a week, maybe much longer, depending on individual. It's a gamble. And it thins out the hair in the back of your head (known as the "donor area"). That's probably why the back of Trump's head looks dodgy in the wind.
Hair loss is important in the IT field because age is frowned upon in our industry. It directly affects our career.
This is surely a sensitive topic and I hope I'm not being too insensitive here, but I've personally never frowned upon someone who has less hair than me. Even if my hair is thicker than that of most people, that only means I have less testosterone in my body that you. It means you are more of a man than I am. Everyone knows that. I say, own it!
I'm not saying people "should be" judged on hair, but in practice they are. If you look old, you score lower in IT interviews. I'm just reporting human nature, not making it. I don't have access to humanity's source code.
Fields like medicine and law value age. I'm jealous of those of fields. In IT you have a grey arrow on your back and have to consciously try to counter it, such as acting enthusiastic about dumb fads that management falls for.
Youngbees don't know better and lick them up with a smile: "Yum yum, block-chain q-bit microservice no-sql serverless node.js++ for our little contract tracking app! Woohoo!" I know better, but STFU to not look like an old-tech-loving geezer.
The holy grail in hair-loss would be one-time fix, or more optimistically, one pill a day.
Today, just to stall your hair-loss / keep hair, you'll need to be on minoxidil (foam / liquid, twice a day) and finasteride and/or dutasteride (pill). Though many will use more products - and as of lately, microneedling your scalp has gained popularity.
Some of these meds have adverse health effects, but in the end - they can be expensive and time-consuming, and results range from poor/no effect, to good.
A hair-transplant could cost you between $10k-$50k, depending on where you get one. Musk has had a HT, but probably needs to stay on the meds mentioned above, to halt any other loss that's going on.
Long story short: The current solutions are expensive and time consuming. It becomes a lifestyle / daily routine, like with other chronic illnesses. And the effects can disappear if/when you can no longer afford them.
