Hey dude, I wish you the best of luck. I've certainly seen evidence (although anecdotal) on this site and elsewhere showing great results from situations more dire than yours.
In my case I've just reached NW2 at age 25. I've sort of been NW1.5 my whole life. My plan right now is an all out assault comparable to yours. However, my only source of hesitancy is eliminating all other causes from my life (poor nutrition and dry hair). I have a horrendous diet. A lot of fast food, soda, beer, processed junk. I rarely eat a balanced meal. I also need to hydrate more. When you were going through your transition was there anything diet or haircare wise you wish you could go back and redo? Do you think it could have played a role in the accelerated hair loss?
