Since Minoxidil does not improve the quality of hair, there is no point in using it any longer. I am already Norwood 0, now the estradiol will increase the thickness of my hair over time. I have already been through this a year ago, it is just that my hair was ruined by testosterone injections this spring, so I am doing it all over again. I think in about 8 months my hair will improve in quality and I will achieve the perfect hair I had at the end of last year and the beginning of this year. In any case, achieving the best possible hair is a matter of time, and it will happen next year.
