I switch hands. I found that I actually get a better shave when I use my left hand than my right, though I'm right handed. 
Here's a blogger that talks about his first HeadBlade experience...

My first experience was pretty much like the bloggers. But by following the advice given here and patience, using the HeadBlade with either hand and getting a great shave is no problem.
Hey guys, I thought i would give you my two cents.
I started with the Mach3 on the first shave. I then proceeded to try the headblade on the second shave. I went against the grain and let me tell you it was the closes shave i've ever had. The problem for me is that there were a few little bumps from the first shave and they got nicked and blead a little. I found that after each shave that i bled a little. I could be doing it wrong.
Having a lack of head shaving products in Aust there isn't much post-shave products designed for head shaving.
After the shave i rinse my head in cold water as everyone has been bragging about. That feels great but makes your head feel a little numb for a few minutes. I then apply some Aloe Vera moisturiser to my dome, let me tell you that it stings like a b*tch for a few minutes. Afterwards it feels great.
What does everyone do to combat dry skin and dandruf? or will this go away.
