Question regarding a 2nd Fue hair transplant

[Flyersfreak]

Ive read that it takes longer for the 2nd HT to come in, is that true? It may take longer to come in but at 18 months you still should see the full result?

I had my 2nd procedure done 2 years after my first one and I am 6 days away from my 6th month mark. Thanks.
