The only true cure that will ever exist for male pattern baldness would be to find and destroy the gene that causes it before conception or at birth, the only thing we can hope for in our lifetime is that they will release a pill that works to re-open the hair follicles and causes hair to regrow, that is a long shot as hair follicles don't just go to sleep, they die out. That being said, the best we will probly get is a pill that is basically propecia but with out the sides and works better. Also something like rogain but stronger, or better yet, a pill that does what Propicia and rogain does combined with zero sides and works twice as good and keeps hair growing for a longer period of time after you get off.
Most likely we will be maintining our hair for the rest of our lives, if we stop, the hair will die and not come back.
You are clearly unaware of what is going on in the science right now. Also, a "cure" as I've said to exhaustion on these forums, is any treatment that relieves the symptoms of the disease — you don't need gene editing for that.
Humans are very emotional creatures. Based on history there will not be a cure for a very long time. Just use what exists and pretend things will stay how they are. There might not ever be a cure its a realistic possibility.
People need to quit using this frankly dumbass reasoning. Based on history, Propecia, Rogaine and transplants shouldn't exist. Based on history, Polio shouldn't have been vaccinated. History is not an indicator of technological or scientific progress in the least; you'd think people using computers and smartphones would know that.
In regards to your question about Tsuji, Michel: Organ Tech stated in their interview with Hairloss Talk that they are still on track to release the treatment to the public, starting in Japan, in 2020.
Histogen is in its final clinical phase (the first treatment to do so since Propecia!) in Mexico and is expected to be released in 2018 as is Shiseido's treatment (Japan) which could potentially be a permanent solution.
The Brotzu lotion is expected to be out 2017.
The way I see it is this:
In the next few years, there are going to be better options to maintain the hair that you have and combined with conventional transplants, it will see a great many people cured.
The 2020s will be the decade where people who've been bald for many years can finally get their hair back.
