That is absolutely not true. The safest levels might not grow hair. I am still evaluating the difference between 2,600 and 106 pg/ml which is just about as high and then about as low an adult female target as one can hit. Now my T levels have been 9 and 7 pmol which is very low but that not be enough just on its own. Now to mention that MtF's can do this for life, "XY's just in it for the hair" have usually a short time threshold in which to get results. Rarely do guys allocate more than one year of HRT to their efforts if they see minimal to no results. So low female targets might result in slower, growth with less shed possibility.
Remember, Bridge saw results right away. Many others moped for months and there were not a lot of other pictures shown. One female with PCOS apparently got no results whatsoever from HRT. She had a weird doll sort of icon. On the other hand in the main study which had only one person, I think both her E levels and T levels were far higher than mine, relatively. We know Bridge's protocols all appeared to grow hair and without delay. Someone else titrating themself might take, a bit like me, five years to reach the "magic" levels. Perhaps there is also a genetic factor while some get better regrowth and having diffuse thinning is probably easier to restore than say an NW5-NW7.
So the jury is still out and Janey knows juries.
Goddess bless and back to sleep,
