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?
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.
Hair loss is important in the IT field because age is frowned upon in our industry. It directly affects our career.
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.
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.
