amanindia,
I realy think you should wait until AT LEAST 9TH months to see any noticable growth.and 12 months to see 80-90% of the result.and after 18 months the true final result.(based on my own experience)
I know some people see much more growth by 6-7th months.but there are many people who see no growth in 6th months.
I'm one of them,I had 2 sessions and I had no significant growth at 6th month.I started seeing improvements in 8-9th month and by 12th month I could really see the result however it took another 6 months after that for the hair to fully mature and thicken..clearly noticable difference between 12 months and 18th months for me.
you should not stress too much,just relax and wait and stay positive.people are different in term of growth.
good luck.
