Do not shave before bathing. The skin just after shaving has a lot of micro trauma that cannot be seen by the naked eye and is more sensitive. At this time, take a bath immediately. The stimulation of bath solution, shampoo and hot water will easily cause discomfort or even redness in the shaving area.
It is not advisable to shave before exercise. During exercise, the blood circulation of the body is accelerated, and a large amount of sweat will stimulate the skin you have just shaved, causing discomfort and even infection. Wei Wen
