You won't regret it. The hardest bit is seeing the new hair, then it falling out during the shed. I would recommend you try some lipogaine minoxidil as well. I buzzed my hair to a 3 during the process, but i was about a norwood 3 anyway, lucky at 47... Keep taking pictures, every month, as it's the best way to assess progress. Basically, it will fall out in the next few weeks and you'll see nothing for months. This is a depressing stage, as you're left thinking "f..k, that was a waste of money".... Then, it starts growing back and you'll have a hairline again. It's a waiting game. I hope you get a great resutl.
