To TakingthePluge's comment of no growth, I would say I have had some growth, but very very disappointing. I had 2000 grafts from the front to the back. and it does not look like it.
At 3 months I contacted the doctor and told him how surprised how little change I had. The doctor reassured me, and informed me that a 2nd HT take 4 to 6 months.
I waited 8 months, and contacted the Doctor again, and the doctor agreed that my hair was "thin", and that I should wait 9 to 12 months, and possibly longer.
