Let's break this one down. So you did the research and it took you less than 6 months. Considering the many factors involved, the number of practitioners and the fact the work is permanent, I would think it would take a bit longer but OK. Some are just driven by the cost.
No, he is not the only one that can do 3500 grafts. This, by itself, does not mean he is good or bad, It all depends on what the patient's goal is. Post photos so we can see.'
Amazing result? How was it amazing?
Were your friends thinning exactly like you? Did they also need 3500 grafts?
Why is the hairline design so natural? Did you take photos?
No one can tell you had something done? After only 6 months you already have a full set of hair? Or no one can tell because nothing has grown yet? Which it it?
Why was the procedure easier? What did you think was going to happen?
4 years? Oh wait, I thought it was 6 months.....
Wasn't there a post just like this one a few months ago?
By posting fake reviews, which is exactly what this is, you are not only building distrusts for yourself but for the entire industry. Consider many people still think of transplants as plugs....add to that a group such as yourselves having to rely on fake reviews....
Why not look at the cases you've completed, (if any), and see if there is anything good there...Perhaps you can post results. Or hire competent staff.....
I agree with @jj51702, you might want to get on Finasteride now before your ht procedure as you still have a decent amount of hair that might succumb to shock loss.
And looking at your photos, for me it’s a tough call whether an HT is a good idea for you now as like JJ said, youre likely to need another procedure if you loose more hair as it does look like it miniaturizing, but your donor looks good and if you’re okay getting another HT when the rest of your native hair recedes then do what will make you happy.
How short the hair needs to be will depend on a number of factors as many have pointed out above...I think it depends on ethnicity. If you're Anglo, and the hair drops right away, 1/4" ought to be sufficient. If you are Asian, for example, the hair tends to stick out when short. It requires length, (and weight) to drop. So maybe an inch?
My suggestion is go to the barber and ask them to cut it as short as possible without being able to see the scars. Once you have the info you can then cut it yourself.
One last thing. The difference between a bad haircut and a good one is 1 week. So, if you do go too short, by mistake, it'll will be OK in a matter of days.
