Welcome mate, you've certainly come to the right place

I am 26 and started losing my hair when I was 13/14, I finally "lost it" just over 5 months ago, and let me tell you mate. I felt instant relief, I like you was not really depressed by it, but I was starting to think about it more then I liked, and was living in hats and stuff...
I'm sure your ears don't stick out any where near as far as you think they do. A lot of how we perceive ourselves is all in our head... That and no one is perfect anyway, and that is what makes us unique. I for one have scars all over my head from different reasons, but I think it just adds to the character of it all, that an no one even notices other the me anyway! If they do, then it is a good little conversation piece.
When it comes down to it, now you have the idea in your head, it is going to be there until you take the plunge. There are 2 ways you can go about it:
Firstly, the shock and awe method. Go grab some hair clippers and your favourite razor and cream and just "have at it". Then the deed is done. You'll be rocking the sly look in no time!
Secondly, you can gradually buzz cut it shorter over the next x period of time until you work your way down to going full sly.
The second method is probably less daunting but it really just depends on how you feel, who knows you might start out to buzz it down gradually, then realise you like the look and just finish it off.
If you decide to be bold and just shave it all off, stick with the 30 day rule, that way you give yourself and those around you time to adjust to the new you, the 30 days will also give you time to perfect your shaving routine and technique, because it's a little different.
