I highly doubt anything groundbreaking is coming in the next 5 years. It isn't feasible. In the next 10 years the only hope for hair is Tsuji's method. If it comes out in 2020 I'll be over the moon, but it isn't happening. Not trying to anger people but please be realistic. Continuing to nuke DHT will be the only solution for the next 5-10 years. If I am wrong, I am very happy to eat my words.
