Alexander Fitzgerald was in his mid-30s when he noticed his hair was thinning at the sides.
The part-time model and journalist said it might not have have been hugely noticeable to others but, as a perfectionist, he found it annoying, and because of his work, he decided to look at his options.
He went for a consultation at Hair Restoration Blackrock, and after speaking with surgeon Maurice Collins, he decided to proceed with a hair transplant, involving removing a strip of skin containing hair from the back of his head.
"I'm very squeamish but it was utterly painless," he says.
"I just sat there for the best part of a day watching DVDs while all this was going on.
"It's a bit surreal as I was sitting eating lunch with a big bandage on my head," he says.
Alexander said that initially his head felt a bit itchy and tight, but he was given a spray to relieve that and stop him scratching.
He also had to avoid showers and exercise for several days to prevent getting wet while the skin healed.
"The end result was incredibly natural; it's not like you come out with an Afro or something," he says.
Alexander did not want to disclose how much he'd spent but considered it worthwhile for him.
"It's not something to be undertaken lightly but if you're concerned about hair loss, it is good to know there is a solution that could work," he says.
