Okay gentlemen, let me have my say!
First of all, I have been taking Dutasteride for over 2 years now and have also had a hair transplant. Although I have a "respectable" head of hair now and Dutasteride has defintely slowed the process down, I would not recommend anyone to go down that route. first of all, having the Hair Transplant means they treat your head like a pin cushion as 2200 grafts get inserted one by one. Secondly, you have a scar on the back of your head for life. I had some more surgery to have that reduced so that I can shave my head again. This makes it less noticeable, but doesn't eliminate the scar. Third, you'll have numbness in the back of your head and where the implants were inserted for a long time after. Finally, Dutasteride is a pain in the neck as you have to take it everyday.
My advice? Accept the stats. 20% of men experience noticeable hairloss by their 20's, 30% in their 30s, 40% in their 40s, and there's a 50% chance you'll be a slaphead by the time you're 50. In hindsight, I wish I had accepted this and saved myself considerable pain and money. There's only one treatment for baldness boys and thats a Gilette Mach 3 razor and an ability to walk around bald and proud! Hey,its not as if its unusual!
Plus, you can take as much Winnie, Dianabol, and Primo as you like and not have to worry about losing a single hair on your head as you haven't got any to lose anyhow!
Finally, since I grew my hair back, serveral people have told me "Hey, we preferred you bald - Go shave that head". I only wish I could, but in the summer, its all coming off no matter how pretty or otherwise the scar revision comes out!
