Welcome to the bald brotherhood Gabacho. Erikwillke said it all.
Welcome. I'll just reinforce that it's important to take is really slow the first few days until you get the hang of it and your scalp toughens a bit.
And very soon you'll be wondering why you waited so long ... even though you don't have thinning hair (thus, you are BBC - Bald By Choice).
Again, Welcome to the Sly world.
