Wow! Love seeing stories like this. You were pretty much totally bald before and now you've got a good amount of hair and a strong hairline. Congrats!
I'm thinking that you should stay with strip for your 2nd HT since you tend to wear your hair a little longer in the back anyway. Also, you'll probably never need to really cut your hair super short the rest of your life. You had such amazing results with strip on the 1st HT, I'd just keep it consistent if I were you.
