I agree with the two gentlemen above!!!
Can't believe you are even thinking about it yet, but that shows how the mind sometime can play tricks on you ;-)
I could understand your feeling if you were 16-20 years old, but since you've already had a transplant, I'd guess you're in your mid 20's or even older, and if so I think you still have a long way to go before needing to think about doing something else with your hair...
