To much exposure to moisture will ruin callus development. Rather than washing your hands several times a day, use an alcohol-based hand sanitizer. It works just as well but doesn't soften your calluses. Also, use dishwashing gloves religiously. Some people even wear rubber gloves in the shower. Personally, this seems a little excessive, but to each his own.
Practicing Tips
Despite how effective Finger Strong is at speeding up callus development, you will only develop great calluses if you actually play. Fortuantely, there are some licks that promote calluses more than others. Any riff or sequence that causes you to slide up and down the neck forces your fingertips to grow callsues. Equally important is bending. Whereas sliding provides the necessary friction, bending provides adeqaute pressure. So pick up your guitar and go for it. If you've never used a looper, look into it. A guitar looper is the best jam buddy you'll ever have.
This video is just an example of the type of movement that promotes calluses. Any variation on slides and bends will work just fine.
Using Finger Strong
When you're first developing your calluses, use Finger Strong three times daily, but only after you play. After you start to see significant calluses developing, use it only as needed for maintenance. To use Finger Strong, simply shake, spray, and shake. That is shake the bottle, spray your fingertips, and shake out your hand. Don't worry Finger Strong is formulated to dry quickly (just a few seconds).
One of the best ways to build calluses is to get lost in a practicing session. There is one website in particular that has awesome practicing tips and routines.
