According to this article it is not allowed to shave with a regular razor while it is allowed to use an electric razor as well as a depilatory (i.e., a chemical substance used to destroy the hair in order to remove hair as well as prevent future unwanted hair growth). The reason given is that shaving pulls the hair taught and destroys the beard. If the beard can still regrow, unlike the result of continual usage of depilatory, how is the beard considered to be destroyed anymore than after using an electric razor?
Also if shaving against the grain (i.e., cutting the hair opposite to the natural direction of hair growth) pulls hair taught and cuts it below the skin why wouldn’t shaving with the grain be allowed as the hair and skin would not then be pulled taught?
Thank you for any insight or explanation.
