Everyone is different. Personally, my growth really came on from 5-7 months and I honestly think my result looked better at 7 months, than it does now. My yield on the right side is definitely weaker than the left, but hey, them's the breaks...at least I have a hairline I can style a bit now.
No matter what, you will benefit from the cosmetic improvement this HT will give you. It's money well spent.
There's nothing more demoralising than watching your appearance change, as your hairline recedes over the years... with that .."who the hell is that in the mirror..." feeling...:eek::eek:
Try not to over analyse it at the moment, as it is still very early.
A bit of JFM will sort out the Grey..
