He had his first HT in 2011? Thats nearly 5 years ago, so he was 24/25...and he had another one two years later.. would you get 2 HT by time your 30?
I don't see what being in spotlight has to do with it, you only get so much hair, and when he needs another one in 5/10 years, or a 4th one, they may find he doesnt have enough donor hair
then he has the rest of his life to live
