21 considering hair transplant? Any advice tips?

[ukcali]

Hi everyone I am looking for some advice and suggestions.

My hair has been receding and thinning on top since my late teens. I have been using Minoxidil for about a year now and it doesn't appear to be working for me. I had a meeting with my dermatologist a few months back who agreed. Obviously that only leaves Propecia which I have more or less decided not to take as the potential side effects for me is just not something I would want to live with.

So I am now looking into a hair transplant. I have been using Nanogen as a cover up which has worked very well, however the problem is my hair line is receding, especially at my temples & crown + it's thinning on top. Therefore it's getting harder and harder to hide my hair loss. It won't be too long before I can't.

I would like to sort my hairline and temples so it will give me more styling options because at the moment I feel pretty limited.

My questions are:
.Will any surgeons do a transplant on a 21 year old? if not why not? I understand the reasoning behind waiting as long as possible but for me I don't see the benefit it waiting to go complete bald before getting a transplant
.One of my main concerns is about thickens of the transplanted hair. A lot of transplants look quite thing, for example Jason Gardner and Silvio Belisconi both seem to have very thin transplanted hair. What outcome is realistic in terms of thickness.

Any other advice would be greatly appreciated. Thanks.
