Even a Great HT - how can you tell?

So let's say you get a very well done transplant - by one of the top doctors.

Can someone still tell if they look closely?

What are the indications - slightly different texture? Spacing of hair looks too even? Or does it depend upon the person?

Or is it virtually non-detectable unless one is knowledgeable in this area and looks very closely?

A hair transplant is virtually undetectable when done well.

but, a HT over-time may not look as good. especially unless one is committed to getting more procedures done and stay on meds. perhaps most pple that get an HT dont care abt how they'd look in 10 or 15 years. i have seen sme HTs that look ridiculous after first few years
