Before you start shaving, it is important to prep your skin and hair. This will help to reduce irritation and make sure that your shave is as smooth as possible. Here are a few things that you should do before shaving with a straight razor:
1. Soften your hair by either taking a hot shower or using a warm towel on your face for several minutes.
2. Apply shaving cream or soap evenly over the area you plan to shave. Be sure to use enough so that the hair is completely covered and lubricated.
3), Using a sharp straight razor, begin shaving in the direction of hair growth (usually downward). Take care not to press too hard against your skin—let the weight of the razor do most of the work . 4) After each stroke, rinse off any lather and stray hairs from blade before continuing 5) When finished, wash off remaining lather with cold water and apply aftershave balm or lotion

Do You Leave Shaving Soap In The Bowl?
The method that is most convenient for you is the one you should choose. To get the most out of your shaving soap, we recommend building the lather in a bowl or mug before applying, as it yields the maximum amount of lather per shave, which is best for a large area of shaving needs.
