Cool Slick Agent, enjoy your stuff. As for useing the gillette blades on the headblade, you have to use the "Atra" blades, if you bought the "sensor or sensor exell" blades you will need the sensor adaptor, which if you send Mac an e-mail at mac@headblade.com he'll probably send them to you at no charge, but double or tripple blades is totaly up to you.
And as for useing regular shampoo and condidioner on your bare scalp, I'm not sure I would recomend that one, the Bald Guyz Wash & Shampoo along with their Condidioner was formulated with the Bald guy in mind, but I would recomend you send an e-mail (personal message) to The Head Bald Guy, that is his screen name here on the forum, and ask him, he can answere all your questions about all of their products. But don't forget about those Head Wipes by Bald Guyz, you can pick them up at your local Walgreens, you'll love them after a hard sweaty day of training and even in between your daily exercises.
All the best
Tom.
