Before becoming a professional shaver, there are 3 basic things to understand.
Knowledge
Shaving is not Rocket Science but it is an art. There's a whole lot more to it than just plainly removing hair. People who see it like this are the ones often plagued with cuts, bruises, and other skin irritations. Deciding the level of reduction you want to achieve is usually the first step. Then proceed to wet Shaving techniques and get it right. You should know the direction of your hair and shave along with it. If you are not familiar with the direction, leave your hair to grow for a while and carefully observe it.
Shaving Products
There are lots of shaving products available in the market today. The most important wants needed for a good shave include, a good DE razor, shaving creams/soaps/gel, shaving brush, after shaves, etc. While there are Expensive shaving products out there, there are some inexpensive ones also. Don't get deceived that the more expensive, the better. There are less expensive products like those offered by Vikings Blade that still provide the same quality as others.
