I don't know have you heard of Dr. Takashi Tsuji, he basically invented hair cloning.
It's only on mouse so far, but human trials should start very soon.
We will have hair as thick as we want if it works, he said it will be released in 2020 in Japan.
Sounds little too early, but you know Japanese, they like to be on time.
